【 摘 要 】

Category:HindfootIntroduction/Purpose:Lateral column lengthening is commonly used to treat foot deformities. The original Evans osteotomy was described to be done 1 to 1.5 cm proximal to the calcaneocuboid joint. A modified Evans osteotomy described by Hintermann is done in the sinus tarsi just anterior to the posterior facet. The suggested advantages of the modified osteotomy are: more stability of the anterior fragment, less probability of injuring the spring ligament, preserving the function of peroneus longus because the osteotomy is posterior to its sulcus, and a better correction. However, no studies have assessed the risk of spring ligament injury, posterior facet injury and middle facet injury. This cadaveric study was done to assess the medial exit point of the osteotomy in relation to the medial structures.Methods:The modified Evans osteotomy was performed by the author who is a foot and ankle consultant in 20 fresh frozen lower limb specimens. Ten were complete lower limb specimens and ten were...
