A posterolateral approach is usually used for these patterns. Comminution and impaction may be observed at the articular margin of the fractured fragment or, more commonly, at the posterior aspect of the distal tibial articular surface. Closed fracture of lateral malleolus of left fibula Closed fracture of left lateral malleolus Left ankle lateral malleolus fracture ICD-10-CM S82.62XA is grouped within Diagnostic Related Group(s) (MS-DRG v 40.0): 562 Fracture, sprain, strain and dislocation except femur, hip, pelvis and thigh with mcc 563 Fracture, sprain, strain and. The displaced fracture fragment usually remains attached to the posterior tibiofibular ligaments. An anterolateral approach is usually used for these patterns. Comminution and impaction may be present at the fracture site, in the distal tibiofibular joint, or at the lateral aspect of the distal tibial articular surface. b) that separate the anterolateral (Chaput) fragment that remains hinged on the anterior tibiofibular ligament. Sagittal lateral split depression fractures (fig.An anteromedial or direct medial approach is usually used for these patterns, but if it is a more oblique fracture involving the posteromedial tibia a posteromedial approach may be preferred. Common sites for occult fractures include the hip, shin, upper arm, and the bones of the ankle, foot, wrist, and spine. Additionally, there can be impaction of the medial aspect of the stable distal tibial articular surface that must be addressed at the time of fixation. Frequently there is an independent osteochondral fragment at the fracture entry site into the ankle joint. In these patterns, impaction and comminution at the medial shoulder of the ankle joint is common. The surgical approach is dependent on the fracture location and the associated articular impaction or comminution. These fractures are partial articular, involving both splitting and depression of the joint surface.
