Complex Tibial Plateau Fractures: Primary Fixation Using the Ilizarov External Fixator. A Two-year Study at Civil Hospital Karachi, Pakistan.

Background The proximal tibia with the meta-diaphysis junction is a critical weight-bearing area. An injury around this region may be restricted to the tibia or associated with a significant soft-tissue injury. The objective of the present study is to assess the results of closed reduction and Ilizarov external fixation in the management of complex tibial plateau fractures. Patients and methods The study included 26 patients with high-energy tibial plateau fractures (Schatzker types V and VI). The ages ranged from 23 to 60 years, with an average of 35 years. The trauma was a road traffic accident in 19 cases and a fall from a height in eight cases. The fractures were closed in 18 cases and open in five. The open fractures were Gustilo-Anderson type I in three cases and type II in five cases. Soft-tissue injuries associated with closed fractures were classified according to the Tscherne system. The follow-up period averaged 24 months. The average time of surgery was 85 mins (range: 60-120 min). The mean time to union was 12 weeks. At the final follow-up, the average total range of knee flexion was 120° (range: 0-170°). Results Results were satisfactory in 22 cases and unsatisfactory in four cases according to Rasmussen's knee functional score. Complications included pin-tract infection in 10 cases, an extension lag in three cases and varus deformity of about 17° in one case. Conclusion Hybrid external fixation is a good method for the treatment of comminuted tibial plateau fractures. It allows for early joint movement and reduces the risk of serious complications.
