Subcutaneous Peroneus Longus Tendon Rupture Associated with OS Peroneum Fracture.

Bilateral peroneus longus tendon rupture through a bipartite os peroneum.

Peroneus longus rupture with associated involvement of the os peroneum is an uncommon injury, and a small number of cases have been reported. Several mechanisms of injury have been suggested, but the most accepted theory is due to an inversion force placed on a cavovarus foot type. The sesamoid often becomes the focal point of the mechanical stresses and may fracture. Although the purpose of th...

Plantar Rupture of Peroneus Longus Tendon Associated to Os Peroneum Fracture: A New Method of Treatment

Most peroneal tendon ruptures are the result of an inversion ankle sprain. Usually tears of the peroneal tendons are partial ruptures called longitudinal tears. Partial and complete rupture of peroneus longus tendon do occur but are far less common than injuries seen in peroneus brevis. The weakest point of peroneus longus tendon is the point where it changes direction and rounds the plantar su...

Progressive retraction of a fractured os peroneum suggesting repetitive injury to the peroneus longus tendon

The os peroneum is an accessory ossicle within the peroneus longus tendon. Prior reports have discussed fracture of the os peroneum with associated tears of the peroneus longus tendon. When the ossicle fractures, there can be varying degrees of retraction of the tendon, which can be diagnosed by malposition of the ossicle or the ossicle fragments. We report a case of a man with recurrent eversi...

Painful Os Peroneum Syndrome: Underdiagnosed Condition in the Lateral Midfoot Pain

Os peroneum is an accessory ossicle located within the peroneus longus tendon. The painful os peroneum syndrome (POPS) results from a wide spectrum of conditions, including fractures, diastases, and other causes. POPS can result in tenosynovitis or discontinuity of the peroneus longus tendon with a clinical presentation of pain in the lateral aspect of the midfoot. Authors report a typical case...
