Clinical analysis of anatomic titanium plate internal fixation in treatment of calcaneus intra-articular fracture

Objective: To investigate the technique and curative effect of calcaneus intra-articular fracture treated with open reduction anatomic titanium plate internal fixation and bridging bone grafting.Methods: 48 cases(56 feet) sanders type Ⅱ-Ⅳ calcaneus intra-articular fracture(type Ⅱ 28 feet,type Ⅲ 21 feet,type Ⅳ 7 feet) were treated with open reduction anatomic titanium plate internal fixation and bridge bone grafting.The reconstruction of the articular facet was observed by X-ray examination at Borden position post-operatively.Also,the Bohler′s angle,Gissane′s angle and Peries′s angle were measured before and after operation.Results: The cases were followed up for 6 to 36 months.The Bohler′s angle,Gissane′s angle and Peries′s angle were all significantly recovered.The differences were statistically significant when compared with pre-operative data(P0.01),but not statistically significant with the healthy side(P0.05).According to the Maryland evaluation system,the total effective rate was 83.9%(47/56).Conclusion: It is an effective approach to treat Sanders type Ⅱ-Ⅳ calcaneus intra-articular fracture with anatomic titanium plate internal fixation and bridging bone grafting.The fixation is reliable,with few post-operative complications and promising curative effect.
