Wagner FC, Neumann MV, Wolf S, et al. - This study was intended to perform biomechanical comparison of these two procedures under dynamic loading conditions. In eight pairs of human cadaveric knee joints, a standardized 34-C3 fracture was created. They were fixed with a 3.5 mm anterior locking plate (LP) or cannulated screws with anterior tension band wiring (hybrid osteosynthesis, HO), following a randomization protocol. It was noted that biomechanical testing indicated significantly less fracture displacement following LP compared with HO both after the first and after 100 cycles. Compared with cannulated screws with anterior tension band wiring, it was noticed that anterior locking plate osteosynthesis of comminuted patellar fractures biomechanically gives better primary stability.
