Treatment of high-energy intra-articular fractures of tibia with Ilizarov external fixator in adults: A tertiary centre experience.

Abstract

To evaluate the clinical and radiological outcomes of the Ilizarov fixator in the proximal and distal fractures of the tibia. This retrospective study reviewed 59 patients having high-energy intra-articular proximal and distal tibia fractures associated with severe soft-tissue injury, who were managed surgically with an Ilizarov fixator. The functional outcome was evaluated by using the American Orthopaedic Foot and Ankle Society scoring system (AOFAS) and the Association for the Study and Application of the Method of Ilizarov (ASAMI) Italy scoring system for tibial plateau and plafond fractures respectively. The most common mode of injury was road traffic accidents. According to the Gustilo open fracture classification, there were 16 patients with grade-I and nine with grade II open fractures. The remaining had closed fractures. According to the Schatzker classification of plateau fractures, 20 were graded as type V and 15 as type VI. According to the AO classification of plafond fractures, 12 fractures were graded as Type-43C1, 5 as Type-43C2, and 7 as Type-43C3. There was delayed union in 11 proximal and four distal fractures, all of which achieved union without additional bone grafting. In proximal fractures, according to AOFAS, out of 35, 26 had an acceptable while nine had a fair result. In distal fractures, according to ASAMI, out of 24, 16 had an acceptable while five had fair results. There were 192/448 wires in 58 patients with pin site infection; all were superficial and settled. Posttraumatic joint arthrosis was noted in nineteen. The postoperative clinical and radiological outcome indicated that primary Ilizarov external fixator is a reliable minimal invasive surgery and definitive fixation method for high-energy intra-articular proximal and distal tibial fractures with compromised soft-tissue. It also offers early stabilisation and painless joint motion without a high rate of complications.
