Abstract: Objective: To study the application of T-model or L-model steel plate in treatment of complicated fracture of tibial plateau.Methods: Eighteen cases were treated by surgery from 1997 to 2002.The fracture was fixed with the T-model or L-model steel plate,the intact articular surface recovered and the spongy bone or artificial bone below the collapse of articular surface implanted simultaneously.Results: The follow-up time was 6 to 32 months and the curative effects were good.Conclusions: The complicated fracture of tibial plateau can be treated by open reduction,fixation with T-model or L-model steel plate and bone grafting.
