Ⅰ期全髋置换术治疗合并股骨头或股骨颈骨折的髋臼骨折

目的 探讨全髋关节置换术(total hip arthroplasty,THA)治疗合并股骨头或股骨颈骨折的髋臼骨折方法、手术特点和疗效.方法 对7例合并股骨头或股骨颈骨折的髋臼骨折行Ⅰ期THA.髋臼骨折按AO分型:A型1例,B型3例,C型3例.股骨头骨折1例,股骨颈骨折6例.伤后7～21 d接受THA,5例行髋臼复位内固定后采用生物型髋臼,2例金属加强环配合骨水泥固定髋臼,股骨侧均采用生物型固定.结果 6例得到随访,平均随访时间3年9个月(2年3个月～6年5个月),出现脱位1例,经手法复位后未再脱位,1例出现异位骨化.所有随访患者髋关节功能均有明显改善,Harris评分术前平均48分,术后提高到91分.随访期内未发现假体松动.结论 THA是治疗合并同侧股骨头或股骨颈骨折髋臼骨折的有效方法,能显著改善关节功能,避免多次手术.

One stage treatment of acetabular fractures combined with ipsilateral femoral head or neck fractures with total hip arthroplasty

Objective To discuss method,operative characters and curative effect of total hip arthroplasty(THA)in treatment of acetabular fractures combined with ipsilateral femoral head or neck fractures.Methods One stage THA was done in seven patients with acetabular fractures combined with ipsilateral femoral head fracture(one patient)or femoral neck fractures(six patients)7-21 days after fractures.There were five males and two females,at age range of 41-65 years(average 50 years).According to AO classification,there were one patient with type A fracture,three with type B and three with type C.Of all,five patients received biological acetabular replacement after reduction and internal fixation of acetabular fracture and two received PMMA acetabular replacement with metal enforcement ring.All patients received biological femoral stem.Results Of all,six patients were followed up for from 2 years and 3 months to 6 years and 5 months(mean 3 years and 9 months),which showed heterotopic ossitlcation in one patient and dislocation in one who recovered after manipulative reduction.The Harris score was increased from mean prooperative 48 points to mean postoperative 91 points.X-ray found no loosening of prosthesis during follow-up.Conclusions THA can improve function of hip joint significantly,avoid further operation and lessen the burden of patients mentally and economically and hence is effective in treatment of acetabular fracture combined with ipsilateral femoral head or neck fractures.
