Abstract
Tibial plateau fractures represent 1 % of all body fractures (1) and 5–8 % of lower limb fractures (2).
The incidence shows a bi-modal distribution, with a first peak encountered in the second to fifth decade males with highenergy trauma such as motor vehicle accidents and a second peak in the fifth to seventh decade commonly females, during lowenergy trauma as in osteoporotic fracture (3).
In osteoporotic elderly patients, this fracture represents as much as 10 % of all fractures (4).
Several fracture classifications exist, and the most widely used is the Schatzker classification.
Lateral plateau fractures are more frequent than medial. Schatzker type II (also known as split-depression type) is the most frequent and is responsible for 25–33 % of plateau fractures (5) and 50–84 % of lateral plateau fractures. (6)
Several fixation methods were used to treat tibial plateau fractures.
In our study we used subchondral screws (Raft construct) for split depression tibial plateau as surgical technique to treat a group of 12 male and 8 female patients with an average age of 46,8 ± 11.5 years (range, 22– 62 years). The etiology of injuries was as follows; 10 were road traffic accident and 6 falls from height 4 were twisting trauma. Mean time from hospitalization to operation was 4.75 days (range, 2-10 days).
The goal of treatment for intra-articular fractures is to restore joint mobility, joint stability, articular surface congruence, and axial alignment, and to avoid posttraumatic osteoarthritis.
The use of a periarticular raft plate in anatomically reduced splitdepression tibial plateau fractures provides sufficient rigidity and prevents collapse.
The radiological and functional results are promising. The functional results were all good or excellent according to KSS and There was no significant loss of knee range of motion and stability.
Active and passive rehabilitation started two weeks after the operation.
The integrity of the articular surface and bone healing was assessed using follow up radiographs.
After significant bone healing was achieved, Partial and full weight bearing were encouraged at 6 and 10 weeks, respectively, at the outpatient clinic.
The patients fully returned to their daily activities without significant disability, at 3-6 months, the average was 4 months.
