CASE-REPORT - FRACTURE OF THE POSTERIOR MEDIAL TUBERCLE OF THE TALUS SECONDARY TO DIRECT TRAUMA

Isolated fracture of the posterior medial tubercle of the talus is a r are injury, generally thought to result from a pronation-dorsiflexion force causing avulsion of the insertion of the posterior talotibial li gament. Originally described by Cedell, the fracture has subsequently been reported three times to our knowledge, with all cases being attri buted to indirect trauma. We describe an isolated fracture of the post erior medial tubercle of the talus caused by direct trauma. The fractu re of the posterior medial tubercle remained ununited, failed to respo nd to conservative therapy, and was treated successfully with surgical excision.
