ABSTRACT
Objective To compare the biomechanical stabilities of 2 fixations for oblique split fractures of tibial plateau. Methods Oblique split fractures of the medial tibial plateau were simulated by osteotomy in 6 pairs of fresh tibia of adult swine. One fracture of each pair was fixed with 3 lag screws parallel to the articular surface whereas the contralateral site was stabilized with 3 lag screws vertical to the fracture line. The maximum anti. Compression load, the maximum power consumption at the maximum load.the load and power consumption at the 2 mm subsidence of articular surface were measured and recorded. Results There were no significant differences between the 2 groups in the maximum anti-compression load. The maximum power consumption at the maximum load, the load and power consumption at the 2 mm subsidence of articular surface. Conclusion Vertical fixation may not provide a biomechanical advanrage over the parallel fixation in stabilizing oblique split fractures of tibia plateau.
