双柱拉力螺钉固定治疗横断髋臼骨折

目的　回顾分析双柱拉力螺钉固定治疗横断髋臼骨折的疗效。方法　 1 3例髋臼横断骨折分别采用Smith Peterson入路或者后外侧K -L入路结合前侧髂腹股沟入路行切开复位 ,前后柱拉力螺钉沿其功能轴固定。术后平均随访 4年 2个月 ,按照美国矫形外科医师协会 (AAOS)标准评估患髋功能。结果　 1 3例中 1 2例获解剖复位 ,1例复位欠佳。术中、术后无严重并发症。患髋术后功能优良率为 85 %。结论　双柱拉力螺钉固定技术是一种治疗髋臼横断骨折的有效方法 ,但技术要求较高 ,应严格掌握手术适应证

Internal Fixation for Bi-columns with Lag Screw in Transverse Acetabular Fracture

Objective To analyse retrospectively outcome of internal fixation with lag screw for bi columns in transverse acetabular fracture.Methods Thirteen cases of transverse acetabular fractures were treated with open reduction and internal fixation using Smith Peterson approach or K-L approach combined with ilioinguinal approach.Both anterior and posterior columns were fixed with lag screws.The average follow up was 4 years and 2 months,and the function of each joint was evaluated according to the criteria proposed by American Academy of Orthopaedic Surgeons(AAOS).Results Twelve of 13 fractures obtained anatomic reduction,another one was identified as unsatisfactory reduction.No severe intraoperative or postoperative complications occurred.According to the AAOS criteria,the rate of excellent and good for joint function was 85%.Conclusion Internal fixation of transverse acetabular fracture with lag screws for bi columns is one of the effective but technically demanding methods,surgical indication should be properly manipulated.
