Radiopaedia.org, the wiki-based collaborative Radiology resource Treatment is determined by the site of the stress fracture and suitability for rehabilitation. The ligament is composed of two layers. Almost invariably, if the fracture involves a paranasal sinus, middle ear or mastoid air cells, then they will contain some blood, which is a helpful clue to the presence of an underlying fracture. Low-risk sites of a stress fracture are at low risk of complications and are under compressive stresses 10,11: lower limb: calcaneus, posterior medial tibial shaft, fibula, lateral malleolus, 2nd to 4th metatarsal shafts, Plain radiographs have poor sensitivity (15-35%)in early-stage injuries, which increases in late-stage injuries (30-70%), due to possible callus formation.. The relationship between fracture fragments can be described using the following terms. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. most hip fractures): 1. Strictly speaking, the fracture is misnamed and should more correctly be called "hangee" fracture. Avulsion fracture of the 5thmetatarsal styloid, also known as a pseudo-Jones fracture or a dancer fracture, is one of the more common foot avulsion injuries and accounts for over 90% of fractures of the base of the 5thmetatarsal. The term "hangman fracture" was introduced by Schneider in 1965 5. Strictly speaking, the fracture is misnamed and should more correctly be called "hangee" fracture. metastasis, bone cyst, etc). 3. The reason is due to the stickiness of clay. Risk factors such as diet, vitamin D and calcium should be addressed to prevent recurrence. An os subtibiale is a rare, genuine accessory ossicle and normal variant related to the posterior colliculus of the medial malleolus 1. Fracture of the coronoid process is thought to result from elbow hyperextension with either avulsion of the brachialis tendon insertion or shearing off by the trochlea 1.. 1991;21(5):367-8.

The Salter-Harris classification was proposed by Salter and Harris in 1963 1 and at the time of writing (June 2016) remains the most widely used system for describing physeal fractures.. "neck of femur fracture", may be written as "#NOF". The radiographic positions should be optimal for the evaluation on plain radiograph to be valid. Examples of soft tissue injuries include: vascular The term is sometimes used to describe intra Due to the aforementioned characteristics, the fracture typically resembles: Salter-Harris 3 fracture on AP Salter-Harris 2 fracture on lateral Small dislocations and the vertical fracture itself are frequently overlooked, and CT is advised if there is concern. Practical points. Fractures at low-risk sites are managed conservatively with analgesia, ice, reduced weight-bearing and modification of activities until pain resolves. Therefore, it is similar to a Colles fracture. In the lower (weight-bearing) limb, there is often a history of a recent increase of physical activity or significant alteration in the type or duration of normal athletic activity. Some authors use the term stress fracture synonymously with fatigue fracture, and thus some caution with the term is suggested. A Jones fracture is a fracture of the proximal metadiaphyseal junction of the fifth metatarsal bone that involves the 4th-5th metatarsal articulations. Treatment and prognosis Fractures in these regions can be classified as: intertrochanteric fracture; pertrochanteric: intertrochanteric, involving both trochanters; subtrochanteric fracture; greater trochanteric avulsion fracture Common Upper Extremity Fracture Eponyms: A Look Into What They Really Mean. Falls, motor vehicle collisions, pedestrian accidents, cycling and diving are common causes of injury 6,7. "neck of femur fracture", may be written as "#NOF". 3. The mechanism of injury is variable, and can occur both during flexion or extension, and with or without compression 5. Fractures can also occur, however, in a variety of other settings. 1985;67(2):217-26. ensure no carpal malalignment or fractures are present Functional weight-bearing such as Robert Jones bandage or elastic bandaging and stiff-soled shoes has better outcomes than non-weight-bearing in a short leg cast 5. It is interesting to note that the word chauffeur comes from the French for "someone who warms" the car engine. Radiographics. The fracture complex results from a direct blow to the malar eminence and results in three distinct fracture components that disrupt the anchoring of the zygoma.

As a historical note, there are four methods of judicial hanging, and the process is more complicated than may be evident at first glance. 3. orbital blow-out fracture; frontal process of the maxilla; Nasal septal hematoma should also be actively assessed. Low-risk sites of a stress fracture are at low risk of complications and are under compressive stresses 10,11: ribs. It is for this reason that the 5 th metatarsal base must be included in the lateral ankle projection of an ankle series, especially when performed for an Fracture. Stress fractures normally present with worsening pain with a history of minimal or no trauma. A Jones fracture is a fracture of the proximal metadiaphyseal junction of the fifth metatarsal bone that involves the 4th-5th metatarsal articulations. Looser zones are also a type of insufficiency fracture. Anterior cruciate ligament (ACL) avulsion fracture or tibial eminence avulsion fracture is a type of avulsion fracture of the knee. Bone and Joint Disorders. Insufficiency fractures are a type of stress fracture, which are the result of normal stresses on abnormal bone. Smith fractures, also known as Goyrand fractures in the French literature 3, are fractures of the distal radius with associated volar angulation of the distal fracture fragment(s). These type of fractures are more common in children, especially aged 5-10 years, due to the elasticity of their bones. bone scans) visualizes bone metabolic changes. ankle and foot: medial malleolus, talus, navicular, 2 nd to 4 th metatarsal necks, 2nd metatarsal base, 5 th metatarsal, hallux sesamoid. Giauque A, Bittle M, Braman J. The mechanism of injury is variable, and can occur both during flexion or extension, and with or without compression 5. The pattern of fracturing depends on the location, direction and kinetic properties of the impact as well as intrinsic features of the skull 2-4. This typically involves separation of the tibial attachment of the ACL to variable degrees. Facial fractures are also discussed separately. A Shepherd fracture refers to a fracture of the lateral tubercle of the posterior process.

Most commonly fractures occur in the setting of a normal bone with acute overwhelming force, usually in the setting of trauma. The Wrist, Diagnosis and Operative Treatment. Mallet finger refers to injuries of the extensor mechanism of the finger at the level of the distal interphalangeal joint (DIP).They are the most prevalent finger tendon injury in sport. Unable to process the form. For example, someone who lives alone may not be able to do so without the use of one arm. The reason is due to the stickiness of clay. The superficial layer has variable attachments and crosses two joints while the deep layer has talar attachments and scapular fracture; clavicle fracture; distal radial fracture (especially Colles fracture) Treatment and prognosis. The complex of the medial collateral ligaments of the ankle joint is collectively called deltoid ligament.It attaches the medial malleolus to multiple tarsal bones. Unable to process the form. CT or MR may be more sensitive than conventional radiographs for detection of avulsion injuries. They should not be confused with fatigue fractures which are due to abnormal stresses on normal bone, or with pathological fractures, the result of diseased, weakened bone due to The use of MRI grading system for bone stress injuries is helpful for predicting recovery time (important especially for athletes). For example, someone who lives alone may not be able to do so without the use of one arm. 1. The superficial layer has variable attachments and crosses two joints while the deep layer has talar attachments and crosses one joint: It should be noted that cartilaginous injuries cannot be detected radiologically and that imaging of simple nasal bone fractures often adds little to patient management. He succeeded Abraham Colles (Colles fracture) as Professor of Surgery at Trinity College, Dublin. There are two classification systems 5,6. CT.

Historically ultrasound was not considered to be the first-line modality to diagnose fractures and has been more commonly used for children. A distance of greater than 6 mm suggests ligamentous injury. Skull fractures are best imaged with CT of the brain. In reality, the majority of fractures that involve the physis have at least a small fragment of metaphysis associated with them and are therefore type II injuries. CT of the skull should be obtained volumetrically with small (<1 mm) voxels and be able to be reconstructed in multiple planes. Males are affected more commonly than females with a median age of injury of 56 years. CT may be useful in differentiating stress fractures from a bone tumor or osteomyelitis if the plain radiographs are negative and bone scans are positive. Anderson and D'Alonzo 4. 2011;14(2):198-208.

It is interesting to note that the word chauffeur comes from the French for "someone who warms" the car engine. Differential diagnosis Radiographic features. Most commonly fractures occur in the setting of a normal bone with acute overwhelming force, usually in the setting of trauma. 7. 4. MRI is the most sensitive modality for detecting stress fracture, and may also be useful for differentiating ligamentous/cartilaginous injury from a bony injury. A Hill-Sachs defect is the terminology of preference over other terms, such as Hill-Sachs lesions, and Hill-Sachs fractures 14.. Repeat dislocations lead to larger defects, which can result in an "engaging" Hill-Sachs defect, which engages the anterior glenoid when the shoulder is abducted and externally rotated 4 (see article: on-track and off-track Falls, motor vehicle collisions, pedestrian accidents, cycling and diving are common causes of injury 6,7.
