Objective To summarize the clinical results of treatment of tibia plateau fracture. Methods Forty-six cases of tibial plateau fractures were treated with operation from Oct. 2007 to Oct. 20l2 in General Hospital of PinGdinGshan Coal Industry Groud. AccordinG to Schatzker classification,6 cases were typeⅠ,8 were type Ⅱ,6 were type Ⅲ,4 were type Ⅳ,l2 were type Ⅴ,and l0 were type Ⅵ. Patients in type Ⅰwere treated with open reduction and fixation with screws,other types were treated with open reduction and internal fixation combined with anatomy or lockinG plates and screws. And bone Grafts were used when severe bone defect after reduction. Results Forty-six cases were followed up from 6 months to l8 months( averaGe 8. 5 months ) . AccordinG to the Rasmussen knee score standard,the satisfactory rate was 89. l%( 4l/46 ). Conclusion Different methods of operative treatment of tibia plateau fracture is recommended accordinG to the type of fractures,quality of the bone and the combination of injury. Soft tissue protection should always be kept in mind durinG operation. Delayed operation,Good restitution and fixation,early exercise of joint and late weiGht loadinG are the key factors in the treatment of tibial plateau fracture.

Objective To explore the therapeutic effect of two-stage delayed open reduction and internal fixation on Pilon fractures.Methods The clinical data of 38 patients with type Ⅱ and type Ⅲ Pilon fracture were analyzed retrospectively.According to the Ruedi-Allgower classification,there were 18 cases with type Ⅱand 20 cases with type Ⅲ fracture.All patients underwent temporary fixation with calcaneal traction or external fixation for 7 to 17 days,and then they were treated with delayed surgery when the soft tissue injuries subsided.Results Follow-up was performed for 10 to 18 months.Based on the Mazur classification,the ankle function in 12 cases was excellent,18 cases as good,6 cases as fair and 2 cases as poor,with a satisfactory rate of 78.9％.Conclusion Two-stage delayed open reduction and internal fixation is a reasonable and effective procedure in treating type Ⅱ and type Ⅲ Pilon fractures with advantages of few complications and satisfactory ankle function.
