Early outcome of hybrid external fixation for fracture of the distal tibia

Objective: To evaluate the early results of treatment when using hybrid ext ernal fixation for fractures of the tibial plafond. Design: Retrospective review of patients treated according to protocol. Pat ients treated with the hybrid fixator were compared with patients treated w ith open reduction and internal fixation. Setting: Orthopaedic trauma service of a Level I trauma center, with a sing le surgeon directing care. Patients/Participants: All patients with fractures of the distal tibia duri ng a five-year period (n = 63) were treated according to protocol, with spe cific criteria determining method of treatment. Eleven patients were lost t o follow-up, and three additional patients were not reviewed for other reas ons. Follow-up period averaged twenty months. Intervention: Fracture stabilization was accomplished with the use of a hyb rid external fixator (n = 34) or with internal fixation (n = 27), as determ ined by patient or fracture criteria. Two patients did not receive planned treatment. Main Outcome Measurements: Range of motion, clinical ankle score, and incid ence of complications. Results: Patients treated with hybrid fixation had lower clinical scores, s lower return to function, a higher rate of complications, more nonunions an d malunions, and more infections. Conclusions: Due to differences in patient populations, the superiority of either treatment method is uncertain; however, hybrid fixation did not seem to solve the problems inherent in severe pilon fractures. The sanguine res ults reported in the literature did not hold true in this group.
