Posterior Malleolus Fractures
Conditions
Brief summary
Patients with a posterior malleolar fracture were recruited and assigned to the direct reduction (DR) group or the indirect reduction (IR) group. Following reduction and fixation of the fracture, the quality of fracture reduction was evaluated in radiograph and CT images. Functional outcome was evaluated at the last follow-up.
Detailed description
Patients with a posterior malleolus fracture were recruited meeting the inclusion criteria of unstable and displaced posterior malleolar fractures requiring surgical management. Patients with open fractures or pathological fractures were excluded. Preoperative anteroposterior (AP), lateral, and mortise view radiographs as well as computed tomography (CT) scans were routinely obtained to evaluate the characteristic of the fracture. Patients were then assigned to the direct reduction (DR) group or the indirect reduction (IR) group. Following reduction and fixation of the fracture using the direct reduction technique or the indirect reduction technique, the quality of fracture reduction was evaluated in radiograph and CT images. Functional outcome,including AOFAS score, ankle range of motion were evaluated at the last follow-up.
Interventions
PROCEDUREdirect fracture reduction and fixation
In the DR group, the posterior malleolar fracture was reduced and fixed in a direct way via a posterolateral approach with the patients in prone position.
PROCEDUREindirect fracture reduction and fixation
In the IR group, the posterior malleolus was reduced through ligamentotaxis following open reduction and internal fixation of lateral and medial malleolar fractures. Percutaneous cannulated screws were used to fix the posterior malleolar in anterior-to-posterior direction.
