title: Crescentic transmalleolar osteotomy for optimal exposure of the medial talar dome.
abstract: A review of the literature suggests that surgical treatment of transchondral talar dome fractures affords superior results over lengthy conservative therapy. Medial lesions have been reported most often. The authors perform stress views in acute and chronic ankle injuries, as there are often associated ligament ruptures with suspected talar dome fractures, and routinely use an air-contrast radiographic technique for visualization of the continuity of the articular cartilage. An arthrogram is performed for definitive diagnosis of ligamentous injury. A new osseous surgical approach to the medial talar dome has been presented, entailing a crescentic osteotomy of the medial malleolus. The distinct advantage has proven to be enhanced exposure to the middle and posterior aspects of the medial margin of the talus. The configuration of the crescentic osteotomy is also amenable to internal fixation and tension band wiring has been recommended. Unrestricted access to the site of a medial transchondral talar dome fracture through this osteotomy is the benefit of a technically well-performed procedure.
