![]() ![]() In addition, the ambiguity of its symptoms makes PLT pathologies a diagnostic challenge. The duration between injury and diagnosis of PLT tear ranges from 6 to 48 mo. Due its low incidence, peroneus tendon pathologies are often overlooked and often misdiagnosed. In contrast, Sobel et al did not report any PLT ruptures in a cadaveric study of 124 ankles. #Palpation n peroneus series#Dombek et al documented 5 cases of isolated peroneus longus tears in their series of 40 patients with peroneus tendon pathologies. Its incidence remains ill-defined and the condition has only been described in case series or cadaveric studies. Due to the PLT’s role in mid and hindfoot stability, surgical correction is often warranted with most authors achieving reproducible results. Non-surgical management rarely yield acceptable outcomes. Patients who are able to relate an initiating injury are defined as acute whilst patients who were unable to are classified as chronic. ![]() PLT pathologies can present acutely or insidiously, typically presenting with chronic pain. In addition, anatomical variability such as the presence of an os peroneum in approximately 20% of the population may predispose to PLT rupture. Varus deformities of the hindfoot or lateral ankle ligamentous laxity can subject the PLT to increased tension and frictional forces at transitional points described above. Incompetence of the superior peroneal retinaculum over the fibula groove can predispose PLT subluxation. These sites are potential sources of attrition and avascularity. ![]() The tendon travels within the posterior fibula groove, passes under the peroneal tubercle of the calcaneus and bends sharply along the cuboid groove before inserting medially at the base of the first metatarsal. The peroneus longus undertakes a tortuous course from its origin at the proximal tibia and fibula to its insertion at the first metatarsal and medial cuneiform. The mechanism of injury is due to a combination of mechanical and anatomical factors. Ruptures of the peroneus longus tendon (PLT) are rare. ![]()
