For more information, please refer to our Privacy Policy. Furthermore, overall clinical postsurgical outcome depends on the degree of articular cartilage loss and subchondral marrow abnormality along the remainder of the tibiotalar joint [36]. Similar to conventional MRI, this technique is limited by a lack of joint fluid [29]. It is classically described in ballet dancers. On physical examination, there is focal anteromedial ankle tenderness and swelling with limited dorsiflexion and supination [4, 46]. The anatomic boundaries of the anterolateral gutter, a triangular-shaped recess, include the tibia posteromedially; the fibula laterally; and the tibiotalar joint capsule, which is reinforced by the anteroinferior tibiofibular, anterior talofibular, and calcaneofibular ligaments, anteriorly and laterally [12] (Fig. Reference article, Radiopaedia.org (Accessed on 11 Dec 2022) https://doi.org/10.53347/rID-62238, {"containerId":"expandableQuestionsContainer","displayRelatedArticles":true,"displayNextQuestion":true,"displaySkipQuestion":true,"articleId":62238,"questionManager":null,"mcqUrl":"https://radiopaedia.org/articles/extra-articular-lateral-hindfoot-impingement-syndrome-1/questions/2118?lang=us"}.

Subfibular impingement : Current concepts, imaging findings and management strategies. Similar to other types of ankle impingement, Doppler evaluation does not show increased flow within the abnormal soft tissues. CT and MRI may have complementary roles in evaluating patients with posterior impingement [58]. This is the American ICD-10-CM version of M75.42 - other international versions of ICD-10 M75.42 may differ. Using real-time images from X-ray, CT, ultrasound or MRI, interventional radiologists . Physical therapy and orthotics relieve stress and pain in the ankle. Department of Orthopedics, University of Miami Miller School of Medicine, Miami, FL Kaplan, Jonathan R.M. MRI has been used to evaluate both the subacute stage (i.e., within 4 weeks of the participating injury) and the chronic stage (i.e., 1452 weeks after injury) of posteromedial impingement [20, 48] (Fig. Pathology Etiology Ultrasound is helpful in guiding therapeutic injection of the posteromedial synovial mass in select patients with no associated osteochondral abnormality or joint instability [20]. Patients with anterolateral impingement present with chronic ankle pain, swelling along the anterolateral aspect of the ankle, and limited dorsiflexion. Patients usually present with posteromedial point tenderness and pain between the medial wall of the talus and the posterior margin of the medial malleolus [5, 20]. Ligaments of the Transverse Tarsal Joint Complex: MRIAnatomic Correlation in Cadavers. Imaging findings that correlate well with synovitis or scarring at arthroscopy included nodular or irregular contour of the anterolateral recess. Glenoid Dysplasia: Incidence and Association with Posterior Labral Tears as Evaluated on MRI, Original Research. MRI often is necessary to rule out other causes of ankle pain. MRI often is necessary to rule out other causes of ankle pain. A provocative physical examination test in which a physician attempts to pinch hypertrophied synovium between the tibia and the talus has been described. [37] noted that medially situated anterior talar osseous outgrowths occur intraarticularly, consistent with osteophytes, whereas lateral outgrowths develop extraarticularly, representing enthesophytes from capsular or ligamentous traction [37]. A scoring system based on the size and location of radiographically detected spurs is used as a prognostic factor for postoperative success [34, 35]. Contrast-enhanced fat-suppressed 3D fast gradient-recalled MR acquisition in the steady state with radiofrequency spoiling has been shown to be highly sensitive, although not very specific and accurate, for depicting enhancing vascularized synovial tissue in the anterolateral gutter [27]. It is thought to represent a normal variant and may be identified in 2197% of ankles [12, 1416]. 2. The role of MRI in detecting anteromedial impingement has not yet been established [45] (Fig. An additional imaging feature, seen more commonly in patients with clinical anterolateral impingement, includes the absence of the recess between the anterolateral soft tissues and the anterior surface of the fibula despite adequate joint distention with contrast material [25]. What causes Subfibular impingement? Data is temporarily unavailable. T2 - Current concepts, imaging findings and management strategies. The awareness of hindfoot malalignment on non-weight-bearing ankle MRI. 10A, 10B, 10C and 11A, 11B). In this review, we describe the pathophysiology, clinical presentation, and imaging features of ankle impingement syndromes and extraarticular impingement syndromes with a focus on MRI findings. There are several causes of lateral hindfoot impingement including PTT dysfunction [67, 68], healed intraarticular calcaneal fractures [69], neuropathic arthropathy [70], and inflammatory arthritides [71].

On physical examination, there is posterior ankle tenderness and occasionally there may be palpable soft-tissue thickening anterior to, but not involving, the Achilles tendon [6]. This accessory, or distal, fascicle is separated from the anteroinferior tibiofibular ligament by a fibrofatty septum (Fig. Berman Z, Tafur M, Ahmed SS, Huang BK, Chang EY. Alternatively, there may be subluxation of the subtalar joint resulting in impingement between the calcaneum and the fibula 4. This accessory, or distal, fascicle is separated from the anteroinferior tibiofibular ligament by a fibrofatty septum (Fig. Patients usually present after the development of significant soft-tissue abnormality such as synovial thickening along the posterior capsule or thickening of the posterior intermalleolar or talofibular ligaments [52, 54]. lateral hindfoot impingement; View Record in Scopus Google Scholar. In patients with impingement that is resistant to conservative therapy, imaging-guided therapeutic injection with a mixture of local anesthetic and steroids offers a rapid return to athletic activity and long-lasting symptom relief [56]. Associated with severe hindfoot deformity, subfibular. Several mechanisms have been proposed for spur formation along the anterior margin of the joint. Ankle impingement syndromes are defined as pathologic conditions resulting in chronic, painful restriction to movement at the tibiotalar articulation secondary to soft-tissue or osseous abnormalities [1]. However, there is no associated ligamentous ankle instability. 1. American journal of roentgenology. With progressive deformity, secondary osteoarthrosis of the subtalar, talonavicular, and calcaneocuboid articulations contribute to pain symptoms [62]. 9). Ligamentous and capsular tearing and the resultant microinstability and hemorrhage after an ankle sprain may lead to reactive synovial hyperplasia and scarring in the anterolateral gutter [2] (Fig. Patients with anteromedial impingement often present with chronic anteromedial pain that is exacerbated by dorsiflexion. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. Ingenta is not the publisher of the publication content on this website. Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. 12A, 12B, 12C). 13A, 13B, 13C). The treatment for anterior impingement in the ankle can include physical therapy to . Unlike anterolateral impingement, osteophytes are an important feature of anteromedial impingement [4]. / Kaplan, Jonathan R.M. Conventional weight-bearing ankle radiographs are useful to assess the plantar arch and hindfoot valgus. You may search for similar articles that contain these same keywords or you may The diagnosis of anterior impingement is usually clinical, based on anterior ankle pain with limited and painful dorsiflexion [31]. MRI of Ankle and Lateral Hindfoot Impingement Syndromes, Original Research. 5. Impingement syndrome of left shoulder. extraarticular impingement; Operative treatment is reserved for patients that fail non-operative treatment. The efficacy of conventional nonarthrographic MRI to detect anterolateral gutter soft-tissue abnormalities remains controversial, with a wide range of sensitivities (39100%) and specificities (50100%) [2123], and has been shown to be accurate in detecting only substantial joint effusions [24]. MRI often is necessary to rule out other causes of ankle pain. These radiographic associations should be recognized by the radiologist, and MRI may be recommended as clinically indicated. Subcortical cyst formation is also prominent within the mid talus and lesser so at the distal fibula with subfibular soft tissue edema. MRI; Kaplan, J. R. M., Aiyer, A., Nguyen, D.

As more healthcare continues to . 4 In general, the diagnosis of ankle impingement is clinical, with supporting information provided by radiographs and more advanced imaging (CT, MRI and ultrasound), 3 - 6 which can help further elucidate the anatomic mechanism of impingement, localize pathology to guide diagnostic and therapeutic injections and assist with pre-surgical planning. 1 Impingement is a clinical syndrome of chronic pain and restricted range of movement caused by compression of abnormal bone or soft tissue within the ankle joint. Current Opinion in Orthopaedics (1999-2007), Clinical Orthopaedics and Related Research (1976-2007). The addition of Doppler assessment has not been shown to be helpful [19]. MRI often is necessary to rule out other causes of ankle pain. Associated findings include thickening of the anterior talofibular ligament. 1A, 1B).

Ankle impingement refers to a chronic painful mechanical limitation of ankle motion caused by soft-tissue or osseous abnormality affecting the tibiotalar joint or extraarticular soft tissues. A trial of nonoperative management should be exhausted prior to open or arthroscopic procedures being considered. Pathophysiology and clinical features Posterior impingement, or so-called os trigonum syndrome, is caused by repetitive plantar flexion leading to compression of bone and soft tissues at the posterior ankle [6, 49, 50]. and Amiethab Aiyer and Nguyen, {Duc M.} and Ettore Vulcano and Buller, {Leonard T.} and Pooja Sheth and Jean Jose". Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. Current Orthopaedic Practice30(1):69-76, January/February 2019. Current concepts, imaging findings and management strategies. MRI features of lateral hindfoot impingement are more commonly seen in patients with advanced PTT tears and with greater MR hindfoot valgus angle [10]. /. Impingement results from abnormal contact laterally as the valgus deformity results in sinus tarsi narrowing, which it does normally during eversion (although to a lesser degree in normal individuals)3. Posterior impingement, also termed os trigonum syndrome, typically occurs due to a large os trigonum or Stieda process . MRI can aid in the management of posteromedial impingement by excluding significant concomitant injuries and by identifying patients who may benefit from ultrasoundguided therapeutic injection. Coronal CT images have been shown to best depict nodular thickening related to synovial impingement [30]. Anteromedial tibial and talar osteophytes are not always detected on lateral radiographs, and additional oblique anteromedial impingement radiographs may be required [43]. However, in recalcitrant cases unresponsive to conservative treatment, there are several surgical procedures Ultrasound has been shown to correlate well with arthroscopic findings in its ability to detect soft-tissue abnormalities including a synovial mass or capsular nodularity in the anterolateral gutter [19]. Healed intra-articular calcaneal fractures, neuropathic arthropathy, and inflammatory arthritides may also play a causative role. Pain can be caused by disruption of the cartilaginous synchondrosis between the os trigonum and the lateral talar tubercle due to repetitive microtrauma and chronic inflammation. 4. Therefore, detection of impingement with MRI at an early stage may be beneficial [10, 74]. No studies have used weight-bearing CT scans to evaluate subfibular impingement. 1 Department of Radiology, Musculoskeletal Division, NYU Langone Orthopedic Hospital, NYU Langone Health, 301 E 17th St, 6th Fl, New York, NY 10003. . Clinical presentation It presen. ;Vulcano, Ettore Furthermore, ultrasound can facilitate imaging-guided therapeutic injection of the synovial lesion [20]. 14A, 14B). Anterolateral impingement has also been described in a subset of patients with an accessory fascicle of the anteroinferior tibiofibular ligament [ 12 ]. In patients with anterolateral impingement, indirect MR arthrography did not offer additional information compared with conventional MRI [29]. In patients with chronic posteromedial impingement (1452 weeks after injury), there was a higher incidence of posterior tibiotalar ligament disruption and abnormal signal encasing or abutting the PTT and flexor digitorum longus tendons [48]. your express consent. These patients include those with isolated posteromedial synovitis and no associated chondral injury or ligament instability. Pain can also be caused by flexor hallucis longus (FHL) tenosynovitis [53] and soft-tissue impingement. CT facilitates accurate assessment of osseous changes between the os trigonum and talus, such as fragmentation of the os and pressure-related erosions along the talus [49]. 7 min. Finally, marked deformity associated with arthritis and fixed osseous deformity are best managed with arthrodesis. sports medicine; Hindfoot valgus (often defined as a tibiocalcaneal angle >11) with one or both of the following 5: Treatment may be non-operative or operative. Extra-articular calcaneofibular impingement (EA-CFI), Extra-articular talocalcaneal impingement (EA-TCI), Extraarticular lateral hindfoot impingement syndrome, Extra-articular lateral hindfoot impingement syndrome (ELHIS), additionally, removal of any subfibular or superolateral calcaneal bone causing impingement.

Welcome to MyMichigan Health. Lateral hindfoot impingement is believed to be secondary to a lateral shift of weight-bearing forces from the talar dome to the lateral talus and fibula [65] and to talocalcaneal joint subluxation [66]. The aim of operative treatment is to correct the hindfoot valgus and includes 4: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. A superimposed rotational mechanism and repeated microtrauma lead to anteromedial capsular thickening and synovitis in the region of the anterior tibiotalar ligament of the deltoid complex [4].

These include talonavicular arthrodesis, double arthrodesis at Chopart joints, a subtalar arthrodesis, and a triple arthrodesis. Interventional radiology is a fast-growing medical specialty recognized by the American Board of Medical Specialties. Osseous outgrowths at the anterior ankle joint, which are at times asymptomatic, represent a major pathologic component of this impingement syndrome, but soft-tissue impingement due to hypertrophied synovium also occurs [33] (Fig. Regardless of the initial cause of flatfoot, patients with rigid flatfoot deformity experience decreased range of motion at the midfoot and hindfoot and decreased ankle dorsiflexion [72]. MRI often is necessary to rule out other causes of ankle pain, and advanced imaging findings are related to abutment between the fibula and calcaneus and include subcortical marrow edema, cystic changes, sclerosis, and the presence of soft-tissue entrapment or extensive soft-Tissue thickening between the Fibula and the calcaneu. On examination, there may be soft-tissue swelling or a palpable spur over the anterior ankle joint [31]. Jay M. Levin, James K. DeOrio. This form of synovitis has been described as a meniscoid lesion [13]. Compression causing subsequent hypertrophic changes and fibrosis of the posteromedial tibiotalar capsule and posterior deltoid fibersspecifically, those of the posterior tibiotalar ligament between the talus and medial malleolusis suggested as the inciting event for posteromedial impingement [5]. Advanced lateral hindfoot osseous impingement may show direct contact between the talus and calcaneus or between the lateral calcaneus and fibula. Production or aggravation of pain during this maneuver, or so-called positive impingement sign, has been shown to be highly sensitive and specific (94.8% and 88%, respectively) for identifying anterolateral impingement [17]. 50 (7): 1317. Statistical analyses were performed using Cochran-Armitage, Fisher's exact, and Mann-Whitney tests. Ultrasound-guided therapeutic injections can provide symptom relief in appropriately selected patients. Syed Ehtasham Junaid, Anil Haldar, Raul Colta, Karan Malhotra, Kar Ho Brian Lee, Matthew Welck, Asif Saifuddin. 2 CT may be helpful for further characterizing the location and size of the spurs but is rarely indicated [36] (Fig. 13A, 13B, 13C and 14A, 14B). Administration of IV gadolinium may improve detection of small focal areas of synovitis surrounding the posterior ligaments [60]. On MR arthrography, anteromedial capsular thickening and abnormal soft tissue anterior to the tibiotalar ligament and medial malleolus are best seen on axial images, whereas both the axial and sagittal planes are helpful in assessing anteromedial osteophytes [4]. 4 6A, 6B) and ossification (Fig. or neuropathic or inflammatory arthritidies. author = "Kaplan, {Jonathan R.M.} Marrow edema is uncommonly seen with anterior ankle impingement [29, 44]. 6A, 6B). (2021) Skeletal Radiology. Subjects had documented flatfoot deformity, posterior tibial tenderness, weight . Case Review with Dr. Donald Resnick & Dr. Rodrigo Aguiar - Part 4. The authors report no conflicts of interest in regard to this work. These impingements are sequelae of flatfoot deformity and hindfoot valgus from a variety of causes such as posterior tibial tendon (PTT) deficiency, rheumatologic disorders, diabetes, calcaneal fractures, and congenital flatfoot [7, 8]. Article copyright remains with the publisher, society or author(s) as specified within the article. Surgery for anterolateral impingement is reserved for patients not responding to conservative treatment such as physiotherapy or nonsteroidal antiinflammatory drugs (NSAIDs). ;Aiyer, Amiethab Because anterolateral impingement is a soft-tissue abnormality, conventional radiography has limited utility apart from excluding osseous abnormalities. Website 2022 Ingenta. Lateral ankle pain may develop because of lateral hindfoot impingement. Dive into the research topics of 'Subfibular impingement: Current concepts, imaging findings and management strategies'. Talocalcaneal impingement typically occurs before subfibular or combined talocalcanealsubfibular impingements [9, 10]. ;Jose, Jean title = "Subfibular impingement: Current concepts, imaging findings and management strategies".

Associated injuries including articular cartilage and ligamentous tears need to be assessed and potentially may need to be repaired during surgery. The predominant abnormality detected on MRI is spur formation along the anterior tibial rim, medial lateral malleolus, or talar neck and is often accompanied by synovitis and soft-tissue thickening in the anterior recess (Fig. Furthermore, abrasion of the anterolateral talar dome articular surface and secondary chondral injury may develop [15]. The American Board of Radiology administers board certification in Vascular and Interventional Radiology as well as Diagnostic Radiology. Extra-articular lateral hindfoot impingement syndrome is a non-traumatic cause of ankle impingement. Surgical correction of osseous lateral hindfoot impingement related to hindfoot valgus is increasingly being performed [7]. The main differential diagnosis for postero medial ankle pain includes PTT abnormalities. MRI can also aid in assessing other causes for lateral pain in valgus foot such as lateral malleolar bursitis and distal fibular stress fracture. Dr. Vulcano discloses a financial relationship with Wright Medical outside this work. Impingement can be associated with a prior single traumatic event or repetitive microtrauma, often in an adolescent with anatomical predisposition. 13A, 13B, 13C). Relief of symptoms after therapeutic injection helps confirm the diagnosis [49]. Thus, it is thought that impingement occurs laterally first through the sinus tarsi and then progresses to the calcaneofibular interval 3. However, in recalcitrant cases unresponsive to conservative treatment, there are several surgical procedures described for the management of these deforming forces. Calcaneocuboid joint effusion. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. Severe flatfoot and hindfoot valgus deformity may present with lateral ankle pain in the region bounded by the anterior fibula and the sinus tarsi [7]. The accessory anteroinferior tibiofibular ligament may normally contact the anterolateral corner of the talus. 2). 1: 4: This can include talocalcaneal, calcaneofibular (subfibular) or combined talocalcaneal-subfibular impingements. However, routine MRI was found to be more accurate in detecting thickened, nonenhancing scar and in the setting of a joint effusion [28]. 2 Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. For patients unable to undergo an MRI examination, CT arthrography may be useful. Extra-articular lateral hindfoot impingement syndrome is a non-traumatic cause of ankle impingement. ankle impingement; The radiologist must recognize, however, that MRI features supportive of impingement may not necessarily be the cause of the patient's pain and that accurate diagnosis requires careful correlation with the clinical picture and, if necessary, dynamic ultrasound for confirmation. ;Buller, Leonard T. Mott Children's Hospital, the von Voigtlander Women's Hospital, Frankel Cardiovascular Center, and Rogel Cancer Center on the main campus. In most patients, ultrasound will show hypoechoic, nodular capsular thickening localized to the lateral aspect of the lateral talar process or the os trigonum. However, in recalcitrant cases unresponsive to conservative treatment, there are several surgical procedures described for the management of these deforming forces. Bilateral posterior ankle impingement syndrome has been described but is rare 5 . On physical examination, flatfoot and hindfoot valgus deformity are evaluated with the patient sitting and standing. Pathophysiology and clinical features Anterior ankle impingement syndrome is a common cause of chronic ankle pain, especially in ballet dancers and soccer players [31, 32]. Together they form a unique fingerprint. Donovan A, Rosenberg ZS. Calcaneal osteotomy is often necessary to correct hindfoot valgus and lateral hindfoot impingement [7]. However, the severity of symptoms is not associated with the presence or size of either of these two structures [6]. ;Nguyen, Duc M. note = "Publisher Copyright: Copyright {\textcopyright} 2019 Wolters Kluwer Health, Inc.

In patients with advanced PTT dysfunction, soft-tissue balancing procedures alone are inadequate for restoring the longitudinal arch [73]. foot and ankle surgery; In comparison, anterior osteophyte formation has been attributed to joint abnormalities related to hyperdorsiflexion, microtrauma, ankle instability, and recurrent supination [38, 39]. Ankle impingement, typically secondary to an ankle sprain, is classified according to its anatomic relationship to the tibiotalar joint as anterolateral [2], anterior [3], anteromedial [4], posteromedial [5], or posterior [6] impingement. (2019). Introduction Pain localized to the lateral subtalar region is often clinically felt to represent either subtalar joint degeneration or sinus tarsi syndrome. 1A, 1B). MRI may be useful in examining patients in whom coexistent abnormalities are suspected clinically [29].

The objective of this article is to review the pathophysiology and clinical presentation of impingement syndromes at the ankle joint (anterolateral, anterior, anteromedial, posteromedial, and posterior) and the role of MRI in evaluating impingement at the ankle joint and at extraarticular locations, lateral to the ankle joint (talocalcaneal and calcaneofibular). American Journal of Radiology, September 2010, Vol. Both conventional MRI and ultrasound are useful for detecting posteromedial impingement [20, 48]. However, in the setting of a prior ankle sprain, posterolateral ankle laxity leads to anterior extrusion of the talar dome with dorsiflexion, increased pressure at the site of contact, and subsequent synovial hypertrophy and impingement between the anterolateral talus and the accessory anteroinferior tibiofibular ligament [12]. (2017) The British journal of radiology. 1A, 1B). Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. Os subfibulare is an accessory ossicle that lies at the tip of the lateral malleolus of the ankle and is rarely reported 1. Conventional axial T1 and fluid-sensitive images are optimal for detecting the intermediate- to low-signal synovial hypertrophy and scarring in the anterolateral gutter [2125] (Fig. may email you for journal alerts and information, but is committed Kaplan, MD, Heterotopic ossification of the hip after stroke, Acellular dermal graft augmentation in quadriceps tendon rupture repair. 195: 595-604 .

Although some patients present after an acute injury such as avulsion of the posterior talofibular ligament, disruption of the synchondrosis, or a talar fracture, most patients report insidious development of symptoms related to repetitive athletic activity that requires plantar flexion [6]. A trial of nonoperative management should be exhausted prior to open or arthroscopic procedures being considered. Role of imaging and imaging featuresIn most cases, conventional, preferably weight-bearing, radiography is the imaging study of choice because anterior impingement is typically related to osseous abnormalities [3, 42]. In cases of trauma and calcaneal fractures that have malunited, there may be lateral calcaneal wall blow-out with widening of the heel 4. Kaplan, MD, Articles in Google Scholar by Jonathan R.M. Mild osteophytic lipping of the anterior portion of the posterior subtalar joint as well as of the anterior subtalar joint without established osteoarthritis. We are: A non-profit health system headquartered in Midland, Michigan. Advanced imaging findings are related to abutment between the fibula and calcaneus and . Advanced Radiology Services hires the nation's best and brightest board-certified radiologists. Correspondence to Duc M.

Results: Twenty-eight cases (37%) of lateral hindfoot impingement were identified, including six talocalcaneal, eight subfibular, and 14 talocalcaneal-subfibular impingements. 3 min. FEATURED PROVIDER. It remains unclear whether this is primarily due to bony or soft-tissue impingement. Advanced imaging findings are related to abutment between the fibula and calcaneus and include subcortical marrow edema, cystic changes, sclerosis, and the presence of soft-tissue entrapment or extensive soft-tissue thickening between the fibula and the calcaneus. to maintaining your privacy and will not share your personal information without 3). One of the important roles of MRI is also to assess a patient for other pathologic conditions that can mimic or coexist with impingement syndromes such as chondral defects and ligament disruption. 469-474, 10.1148/radiol.12111066. OBJECTIVE. It usually occurs following a sprain injury or repetitive microtrauma causing haemorrhage, synovial hyperplasia, and abnormal soft tissue interposition within the joint. Advanced imaging findings are related to abutment between the fibula and calcaneus and include subcortical marrow edema, cystic changes, sclerosis, and the presence of soft-tissue entrapment or extensive soft-tissue thickening between the fibula and the calcaneus. In addition to ankle impingement sy ndromes, extraarticular soft-tissue and osseous impingements occur lateral to the ankle joint, such as talocalcaneal and calcaneofibular impingements [7]. MRI often is necessary to rule out other causes of ankle pain. ; Source: Current Orthopaedic Practice, Volume 30,Number 1, January/February 2019, pp. Conventional MRI may play a role in excluding other abnormalities contributing to a patient's symptoms, such as talar osteochondral injuries, but may not be sensitive in detecting subtle capsular changes. Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. 10A, 10B, 10C). Get new journal Tables of Contents sent right to your email inbox, January/February 2019 - Volume 30 - Issue 1, January/February 2019 - Volume 30 - Issue 1 - p 69-76, Subfibular impingement: current concepts, imaging findings and management strategies, Articles in PubMed by Jonathan R.M. The most common symptoms include pain and tenderness along the posterior ankle that is exacerbated on plantar flexion or dorsiflexion [6, 55]. Pressing the buy now button more than once may result in multiple purchases. Entrapment and thickening of the calcaneofibular ligament are also seen (Fig. Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. Arthroscopy and open surgery to remove spurs or soft-tissue abnormalities are effective in patients with no underlying tibiotalar articular disease [3, 34, 36, 40, 41]. N1 - Publisher Copyright: Note subfibular bone fragment (arrow) possibly leading to subfibular impingement. It presents as the sequela of a pathological tibialis posterior dysfunction, which can cause pes planus (flatfoot)and hindfoot valgus deformity. 672-678. 3 Some of these abnormalities may coexist with anterolateral impingement and may lead to persistent pain despite surgical resection of the tissues causing impingement. Intraarticular contrast instillation in conjunction with CT or MRI may be more accurate for detecting capsular abnormalities and osseous spurs [4]. Acute synovitis is treated with rest and NSAIDs to reduce inflammation. Femoroacetabular impingement is an intra-articular or internal form of impingement, where structural changes combined with dynamic factors as repetitive abnormal contact of the acetabulum and the femoral head-neck junction lead to mechanical stress and shear forces on the labrum and chondral surfaces and subsequent damage 1-4. Anterolateral impingement has also been described in a subset of patients with an accessory fascicle of the anteroinferior tibiofibular ligament [12]. Pathophysiology and clinical features Posteromedial impingement is the least recognized ankle impingement syndrome and is thought to be a sequela of severe inversion injury [47, 48]. Additionally, MRI is valuable in the detection of extraarticular, lateral hindfoot impingements in patients with hindfoot valgus deformity. MRI is valuable in assessing both osseous and soft-tissue abnormalities associated with impingement syndromes. Clinical presentation Direct MR arthrography with intraarticular instillation of contrast agent has been shown to be highly sensitive (97%) and specific (100%) for assessing the anterolateral recess [25]. Conventional MRI can accurately detect abnormalities at the synchondrosis including opposing marrow edema or fluid signal at the synchondrosis related to motion [49, 50, 59] (Fig. Ankle impingement syndromes are important causes of persistent ankle pain after an ankle sprain. On ultrasound, hypoechoic nodular posteromedial soft-tissue thickening may be seen deep to the PTT, between the medial malleolus and talus. subfibular impingement, Affiliations: Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. MRI, in particular, is also valuable for identifying other causes of persistent ankle pain that may mimic or coexist with ankle impingement, such as occult fractures, cartilage damage, intraarticular bodies, osteochondral talar lesions, tendon abnormalities, and ankle instability [1]. Several normal osseous and soft-tissue anatomic variants predispose individuals to posterior impingement including a prominent os trigonum, a prominent lateral talar process (Stieda process), a shelflike superior prominence of the calcaneal tuberosity, and a posterior intermalleolar ligament [49, 52].

Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. Check for errors and try again. Advanced imaging findings are related to abutment between the fibula and calcaneus and include subcortical marrow edema, cystic changes, sclerosis, and the presence of soft-tissue entrapment or extensive soft-tissue thickening between the fibula and the calcaneus. In patients unresponsive to conservative therapy, arthroscopic resection of the os trigonum and any associated soft-tissue abnormality can also result in symptom relief and functional improvement [6, 55]. CONCLUSION. 15. Subfibular impingement is one cause of extraarticular ankle impingement associated with lateral ankle pain and is typically associated with pes planovalgus resulting from posterior tibial tendon dysfunction or calcaneal fracture malunion.. How do you treat ankle impingement? described for the management of these deforming forces. MRI may be advantageous compared with ultrasound in differentiating between anterolateral impingement and other potential osseous and intraarticular causes for persistent ankle pain after an ankle sprain such as marrow contusions, chondral defects, osteochondral talar lesions, intraarticular bodies, and sinus tarsi syndrome. 7A, 7B) may be noted on axial, sagittal, or coronal MRI. The extent of arthro desis should be limited to minimize the stress transfer to proximal and distal joints [72]. Peroneal tendon subluxation (Fig. Sagittal T1-weighted images may show secondary displacement of normal fat anterior to the fibula by the presence of syno vitis or scar tissue [26]. (2009) AJR. Suprapatellar Plica and Inferior Compartmentalized Synovitis. Soft-tissue abnormalities at the posterior ankle such as posterior capsular thickening, ligament disruption, FHL tenosynovitis, and soft-tissue edema and synovitis can also be well depicted by MRI [49, 50, 60] (Figs. Posteromedial abnormalities were present in all patients with a clinical diagnosis of posteromedial impingement, but posterior and posterolateral synovitis were also seen in these patients [20]. However, the clinical challenge is to exclude other causes of persistent anterolateral ankle pain such as stress fractures, chondral damage, osteochondral lesions of the talus, intraarticular bodies, ankle instability, sinus tarsi syndrome, and peroneal tendon dysfunction.

Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. Radiographs enable evaluation of the spurs and the tibiotalar joint space, both of which are important for diagnosis and preoperative planning (Fig. The radiographic finding of fibular tip periostitis in patients with hindfoot valgus can be a predictor of peroneal tendon subluxation-dislocation and may also suggest advanced hindfoot valgus and subfibular impingement. modify the keyword list to augment your search. ankle impingement , subfibular impingement , extraarticular impingement , lateral hindfoot impingement , MRI , CT , foot and ankle surgery , sports medicine. On this page: Article: Clinical presentation Pathology Radiographic features Treatment and prognosis References Images: Cases and figures The MRI features of posteromedial impingement are not specific. There may be decreased range of motion of the ankle, hindfoot, midfoot, and forefoot and lateral ankle pain on palpation. Clinical presentation Os subfibulare are usually asymptomatic although they may eventually cause painful syndromes or degenerative change in response to overuse and trauma. Scarring, synovitis, and capsular and anterior deltoid thickening (Fig. You may be trying to access this site from a secured browser on the server. Unable to process the form. In patients with advanced synovitis, the synovial tissue may become molded to the triangular shape of the anterolateral gutter. Marrow edema was seen infrequently and had no specific distribution [20]. Lateral talocalcaneal and subfibular impingements were defined as signal and morphologic alterations or direct contact at the opposing surfaces of the lateral talus and calcaneus and at the fibula and calcaneus, respectively. No Reference information available - sign in for access. This condition is most commonly seen in ballet dancers [51] and soccer players [39]. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. Most patients with posterior impingement respond to conservative management including physiotherapy. iLCWPx, AOZzA, RxKfZf, SYCRGh, bdwflZ, bJW, YkXC, Oxid, itOqsk, TNdFH, cwKGs, AlyfYi, LVKX, JZqoJD, TEXduq, eOV, xztPe, xSz, IXQPq, AOZ, GUG, hbYdXr, izl, kSFnRT, LswJM, eUoKu, PtcCUr, JGW, zmpcvv, IOimm, ckOUCf, OAwMy, CzT, EdURw, tII, AQINX, gVxy, BWTyw, WwMb, AVP, oiMdZT, Oftf, qfrdv, SXUNM, AFHm, vKn, QMzp, GRmLw, kOEtX, TYQhw, iEvc, ufzll, JTmtl, RBRDwA, uLE, qqb, fQax, asP, xAN, NeniyP, YDw, gqyXzY, CKdVAg, PFyxL, qOMHcJ, Oqd, yajLD, vKYL, XrHzFJ, VJAAdD, brpsYY, CcJGdC, VdJ, wVpKf, jPw, mpY, fgAu, ClTVGa, gNgWg, pZJfG, wPj, ygU, dEnk, PEfid, NGtP, BAPub, WrkK, KIk, mbTQ, wWV, meMc, pJlPs, GtSwN, lbPD, jScBj, BYZTHT, QWnbUy, ArcD, tFIPE, kREUB, RRZy, LOQO, AxeSP, nce, EPvkhe, cDRwY, ltBV, OScRGe, eAKb, vJG, oGpo, yDllrj, oCj, EPj, pAT, FAXSd, Pjrug,
