The Evans technique is a surgical procedure to treat the mechanical instability of the lateral ankle ligaments. [1] [2]In the Evans procedure, [3] the peroneus brevis muscle is separated from its musculotendinous compound and its proximal end is sutured to the peroneus longus.
The Broström operation (or Broström-Gould technique) is a repair of ligaments on lateral ankle. It is designed to address ankle instability. More importantly, it is primarily used to repair the anterior talofibular ligament (ATFL) in the ankle. It is thought that the majority of patients regain most function in their ankles.
The surgery is also performed in severe cases of pulverized or infected open fractures. Generally, the surgical procedure involves making an anterolateral incision, stripping the ligaments from both malleoli and the calcaneus so that the foot can be displaced posteriorly.
Certain fracture patterns are stable and are thus treated without surgery similarly to ankle sprains. Unstable fractures require surgery, most often an open reduction and internal fixation (ORIF), which is usually performed with permanently implanted metal hardware that holds the bones in place while the natural healing process occurs.
Ligaments of the ankle. In medicine, the Ottawa ankle rules are a set of guidelines for clinicians to help decide if a patient with foot or ankle pain should be offered X-rays to diagnose a possible bone fracture. Before the introduction of the rules most patients with ankle injuries would have been imaged.
X-ray of trimalleolar fracture repair with plate and nails. Surgical repair using open reduction and internal fixation is generally required, and because there is no lateral restraint of the foot, the ankle cannot bear any weight while the bone knits.
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]
posterior talofibular ligament; 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.
