Posterolateral bone graft of the tibia.

Abstract

A series of 30 high-energy tibial diaphyseal fractures in 30 patients were treated with posterolateral bone grafting (1984-1987). All of the fractures were open, a majority being Gustillo Type III with significant soft-tissue injury, comminution, or segmental bone loss. The common mechanisms of injury included motorcycle, pedestrian versus automobile, and motor vehicle accidents. Nineteen of 30 fractures were treated with a posterolateral bone graft within six months of the initial injury, and 11 of 30 were grafted after established nonunion. Union was obtained in 29 of 30 fractures (97%). Healing time from the time of grafting ranged from three to 12 months, with an average of 4.7 months. One patient had a below-knee amputation because of uncontrolled chronic osteomyelitis, drainage, and nonunion. Posterolateral bone grafts consistently produced rapid healing of delayed union as well as established nonunion.
