RESULTS: Os peroneum fragment separation of 6 mm or more or displacement of the proximal fragment by 10 mm or more on a lateral radiograph or 20 mm or more on an oblique radiograph was associated with full-thickness peroneus longus tendon tear in seven of seven patients (100%). Arch Trauma Res. Lamm BM, Myers DT, Dombek M, Mendicino RW, Catanzariti AR, Saltrick K. Magnetic resonance imaging and surgical correlation of peroneus brevis tears. Peroneus brevis. Background: Nonunion of classic Jones fractures has typically been attributed to the precarious vascular anatomy of the proximal fifth metatarsal. Dr Jbara also discusses the mechanism of injury as well as the classification systems and X-ray evaluation of adult talar, calcaneal, midfoot, base of 5th, stress, and sesamoid fractures. Despite what should be a simple entity, controversy exists, as well as confusion in the literature, with the term Jones fracture sometimes liberally (and incorrectly) applied to this fracture. Content is reviewed before publication and upon substantial updates. It usually does not reach the tarsometatarsal (metatarsocuboid) joint, but occasionally does. With this knowledge, we propose a novel classification based on the injury mechanism, which can serve as a reference for clinical treatment and diagnosis. The peroneus brevis tendon is anterior to the peroneus longus at the level of the fibula, contained in a shallow groove at the posterior fibula and held in place by the peroneal retinaculum.

Background: Lacking rational basis for the postoperative treatment of fifth metatarsal avulsion fractures. Together the tendons wrap around the lateral malleolus, specifically within the retromalleolar groove of the distal fibula. MATERIALS AND METHODS: MR images, medical records, and surgical findings were retrospectively reviewed in the cases of 12 patients who underwent surgery because of suspected peroneal tendon tear (14 tendons). The peroneus brevis tendon is positioned between the peroneus longus tendon and the retromalleolar groove of the fibula, likely predisposing it to injury from mechanical wear, particularly in dorsiflexion. It can be caused by traumatic traction (repetitive long-term or a single high impact traumatic traction) of the ligament or tendon. 4. This can result in .

It helps with flexion, the ability to point your foot away from the body, as well as eversion, which is tilting the sole of the foot away from the body. Conclusion: The lateral band of the plantar fascia and peroneus brevis play a major role, either separately or together, in avulsion fractures of the fifth metatarsal base. Ultrasound has a high sensitivity (100%) and specificity (85%) for identifying tendon tears 3: MRI has variable reported accuracy for clinically or surgically confirmed injury, with positive predictive value as low as 48% 2 and sensitivity/specificity as high as 83% and 75%, respectively 7. 4. Other severe injuries of tendon include tear or avulsion. These conditions may arise: Treatments for sprains, dislocations, or other conditions of the peroneus brevis range from physical therapy to pharmaceutical treatments and surgeries.

Peroneal Tendon Tears and Instability represent a spectrum of traumatic injuries to the lateral ankle that include tenosynovitis, tendinopathy, tendon tears and/or tendon instability. The peroneus brevis and peroneus longus tendons are rarely torn simultaneously. Gray's Anatomy for Students: With STUDENT CONSULT Online Access, 3e. Insertion. Other anatomical variants can predispose to injury: As the brevis tear develops, the longus tendon moves anteriorly, which further antagonises the injury and prevents healing. After rounding the lateral malleolus of the ankle, it terminates at the fifth metatarsal bone of the upper and outer side of the foot. Gray's Anatomy for Students: With STUDENT CONSULT Online Access, 3e. Some authors believe that it is due to the lateral cord of the plantar aponeurosis which also inserts at the base, rather than the peroneus brevis tendon 2. These fibers arise from the distal side (farthest from the middle of the body) of the fibula, next to the anterior intermuscular septum (a band of tissue dividing the lateral and anterior or front-facing compartments of the leg).

Pathology Traditionally this avulsion fracture has been ascribed to the insertion of peroneus brevis and is caused by forcible inversion of the foot in plantar flexion, as may occur while stepping on a curb or climbing steps. The peroneus brevis, sometimes called the fibularis brevis muscle, is the shorter and smaller of two lateral leg muscles running down the outer sides of each lower leg. An avulsion fracture is where a fragment of bone is pulled away at the ligamentous or tendinous attachment. Specifically, this muscle is associated with two different activities: The location of the peroneus brevis makes it particularly prone to injury problems. This can be remembered using the memory aid: "brevis closer to bone" (closer to the bones of the ankle, anteromedial to the peroneus longus tendon). Cadaveric studies have shown a prevalence of ~25% (range 11-37%)6. Avulsion fracture of the 5th metatarsal styloid. Acute injuries of the peroneus brevis tendon include tendinitis; avulsion of the insertion with or without bone fragment, i.e., styloid fracture of the fifth metatarsal; lacerations; and acute dislocation with or without a "rim fracture." Chronic lesions Injuries to the peroneal tendons are common. Usually tendons tears occur longitudinally. Lateral surface of styloid process of 5th metatarsal base. The peroneus brevis is composed of striated skeletal muscle fibers, which are the type that you can voluntarily control. At approximately two-thirds of the way down the fibula, the peroneus brevis coalesces into a broad flat tendon. The purpose of the present study was to evaluate the influence of the peroneus brevis (PB) tendon on the stability of fractures of the proximal fifth .

Pathology Traditionally this avulsion fracture has been ascribed to the insertion of peroneus brevis and is caused by forcible inversion of the foot in plantar flexion, as may occur while stepping on a curb or climbing steps. Besides biological factors (i.e., poor vascularization), mechanical instability induced by the pull of the peroneus brevis tendon (PBT) contributes to deficient Jones fracture healing. Despite this theory, the operative treatment of these fractures utilizes biomechanical solutions. In general, these fractures can be treated conservatively, and heal well 2. Jones fracture (metaphyseal-diaphyseal junction): Fracture line extends into or towards the articulation between the bases of the 4th and 5th metatarsals (measuring from the proximal tip of the 5th metatarsal, >0.5 cm and <1.5 cm) Have relative poor blood supply, heal more slowly, and are prone to delayed union and nonunion. Small published case series include patients ranging from 13 to 65 years of age 2,4. 1.
