摘　　要：目的:探讨高偏心距股骨柄假体在初次全髋关节置换中的应用。方法:2015年1月至2017年6月使用Corail高偏心距股骨柄假体(KHO型)行初次人工全髋关节置换的51例单侧髋关节病变者进行回顾性研究,女20例,男31例;年龄21~71(50.8±13.3)岁。分别在术后髋关节正位X线片上测量外展力臂、股骨偏心距、髋臼偏心距、下肢长短差异。记录患者手术前后的Harris评分及相关并发症,并分析假体的稳定性。结果:患侧股骨偏心距、联合偏心距、外展力臂均明显大于健侧(P<0.05)。患侧髋臼偏心距与健侧比较,差异无统计学意义(P>0.05)。17髋(33.3%)的股骨偏心距得到了正常重建,其中15例(88.2%)双下肢等长。34髋(66.7%)股骨偏心距大于健侧,34例(100%)双下肢等长。51例患者获随访,时间(42.3±7.3)个月,Harris评分由术前的(38.0±7.6)分提高至末次随访时的(92.1±3.1)(P<0.001)。结论:高偏心距Corail假体在在单侧初次全髋关节置换中虽未能正常重建股骨偏心距,但并不影响下肢长短的重建和假体的稳定性。Objective:To investigate the application of high offset femoral stem prosthesis in primary total hip arthroplasty.Methods:From January 2015 to June 2017,51 patients with unilateral hip diseases who underwent primary total hip arthroplasty with Corail high offset femoral stem prosthesis(KHO type) were selected for retrospective study,including 20 females and 31 males;the age ranged from 21 to 71 years old with an average of(50.8±13.3) years old.The abduction arm,femoral offset,acetabular offset and the length of lower limbs were measured on the positive X-ray film of hip joint after operation.Harris scores before and after operation and related complications were recorded,and the stability of prosthesis was analyzed.Results:The femoral offset,combined offset and abduction arm of the affected side were significantly greater than those of the healthy side(P0.05).The femoral offset of 17 hips(33.3%) was reconstructed normally,of which 15 cases(88.2%) had equal length of both lower limbs.The femoral offset of 34 hips(66.7%) was greater than that of the healthy side,and 34 cases(100%) had equal length of both lower limbs.All 51 patients were followed up for(42.3±7.3) months.The Harris score increased from38.0±7.6 before operation to 92.1±3.1 at the final follow-up(P<0.001).Conclusion:Although the high offset Corail prosthesis can not normally reconstruct the femoral offset in unilateral primary total hip arthroplasty,it does not affect the reconstruction of the length of lower limbs and the stability of the prosthesis.
