ObjectivesTo present a case series of patients with posterior bicondylar tibial plateau fractures treated by direct exposure and buttress plate fixation through posterior inverted L-shaped approach.MethodsBetween August 2007 and July 2010, eight middle aged patients were identified to have posterior bicondylar tibial plateau fractures. All the eight patients underwent direct fracture exposure, reduction under visualization, and buttress plate fixation through posterior inverted L-shaped approach.ResultsAll the cases were followed for an average of 28.1 months (24-36 months). All the cases had satisfactory reduction except one case, which had a 3-mm stepoff postoperatively. None of the complications such as infection, necrosis of the skin incision or the loosening and breakage of the internal fixator occurred. The average radiographic bony union time and full weightbearing time were 11.5 weeks (10-14 weeks), and 13.8 weeks (11-17 weeks) respectively. The average range of motion of the affected knee was from 3.6° to 127.8° at 1 year after the operation.ConclusionsThe posterior inverted L-shaped approach would not involve osteotomy, tendotomy or division of muscles, while allowing satisfied visualization of the entire posterior aspect of tibial plateau and appropriate placement of hardware. This approach is a safe and effective way for the treatment of posterior bicondylar tibial plateau fractures.
