Objective To evaluate the biomechanism of three kinds of internal fixations in treatment of complex tibial plateau fractures. Methods Eighteen human antiseptic cadaver tibial plateau specimens were used to make models of complex tibial plateau fracture (type Ⅵ fractures of Schatzker classification). The models were fixated with a lateral Golf-buttress plate (GP), modified dual plate (a lateral Golf-buttress plate plus a medial five-hole one-third tubular antiglide plate) (DP) or a lateral locking compression plate (LCP) respectively to compare strength, rigidity and stability of different fixation methods. Results The biomechanical strength, rigidity and stability in DP group and LCP group were better than those in GP group (P<0.05), while there was no statistical difference between LCP group and DP group (P>0.05). Conclusions Locking compression plate and modified dual plate are fairly ideal internal fixators for treatment of complex tibial plateau fractures. In the meantime, locking compression plate emphasizes conservation of soft tissues and blood supply, can better meet the requirement of the biological fixation of fracture and is the most ideal internal fixator at present.
