Incision is made over border of lateral malleolus; peroneal tendon exploration would require a posterolateral longitudinal incision; Surgeons care for peroneal tendons, sural nerve and lesser saphenous vein (which might be ligated), and branches of the superficial peroneal nerve;
A bimalleolar fracture is a fracture of the ankle that involves the lateral malleolus and the medial malleolus. Studies have shown [ 1 ] that bimalleolar fractures are more common in women, people over 60 years of age, and patients with existing comorbidities.
Lateral malleolus, medial malleolus, posterior malleolus, bimalleolar, trimalleolar [1] Causes: Rolling the ankle, blunt trauma [2] Diagnostic method: X-rays based on the Ottawa ankle rule [2] Differential diagnosis: Rheumatoid arthritis, gout, septic arthritis, Achilles tendon rupture [2] Treatment: Splinting, casting, surgery [1] Frequency ~1 ...
Bone tenderness along the distal 6 cm of the posterior edge of the tibia or tip of the medial malleolus, OR; Bone tenderness along the distal 6 cm of the posterior edge of the fibula or tip of the lateral malleolus, OR; An inability to bear weight both immediately and in the emergency department for four steps.
A trimalleolar fracture is a fracture of the ankle that involves the lateral malleolus, the medial malleolus, and the distal posterior aspect of the tibia, which can be termed the posterior malleolus. The trauma is sometimes accompanied by ligament damage and dislocation. [1]
A fractured fibula in addition to detaching the medial malleolus will tear the tibiofibular syndesmosis. [2] The combined fracture of the medial malleolus, lateral malleolus, and the posterior margin of the distal end of the tibia is known as a "trimalleolar fracture". [3] An example of Pott's fracture would be in a sports tackling injury.
The calcaneofibular ligament is a narrow, rounded cord, running from the tip of the lateral malleolus of the fibula downward and slightly backward to a tubercle on the lateral surface of the calcaneus. It is part of the lateral collateral ligament, which opposes the hyperinversion of the subtalar joint, as in a common type of ankle sprain. [1]
The posterior talofibular ligament runs horizontally between the neck of the talus and the medial side of lateral malleolus calcaneofibular ligament; The calcaneofibular ligament is attached on the posteromedial side of lateral malleolus and descends posteroinferiorly below to a lateral side of the calcaneus.
