Objective To analyze the surgical indications and surgical techniques of cemented femoral revision. Methods We retrospectively studied 45 cases (19 males and 26 females) at ages of 59-67 years (average 64 years) receiving the cemented femoral revision from January 1998 to December 2001. Among them, there were 9 cases with stem loosening and 7 with acetabular arthritis after femoral head replacement; 17 with stem loosening, 2 with stem fractures and 10 with stem/cup loosening after total hip...

Objective To analyze the surgical indications and surgical techniques of cemented femoral revision. Methods We retrospectively studied 45 cases (19 males and 26 females) at ages of 59-67 years (average 64 years) receiving the cemented femoral revision from January 1998 to December 2001. Among them, there were 9 cases with stem loosening and 7 with acetabular arthritis after femoral head replacement; 17 with stem loosening, 2 with stem fractures and 10 with stem/cup loosening after total hip replacement. All patients were revised in one stage. Cemented components were used and bone grafts adopted when necessary. Results After operation, there did not exist infection, dislocation or neurovascular complication. Six months later, patients could walk without crutches. Posterior to a follow-up for average 23 months (6-40 months), all hip joints functioned well and the Harris score increased from preoperative 35.0 to postoperative 88.5. Conclusions Loosening is one of the commonest reasons in revising hip arthroplasty. The cemented femoral revision is suitable for those with senile osteoporosis and failed cementless reconstruction and those who need allograft prosthetic composites and reimplantation for sepsis with antibiotic-impregnated bone cement. Revision arthroplasty demands skilled surgical techniques and advanced surgical tools. Preoperative planning is one of essential steps.

目的 探讨非感染性股骨侧骨水泥假体翻修术的手术指征及手术技巧。 方法 回顾性分析 1998年 1月~ 2 0 0 1年 12月接受股骨侧骨水泥假体翻修术患者 45例 ,其中男 19例 ,女2 6例 ;年龄 5 9~ 67岁 ,平均 64岁。翻修原因中 ,人工股骨头置换术后柄松动 9例 ,髋臼磨损 7例 ,全髋置换术后柄松动 17例 ,柄断裂 2例 ,髋臼松动或臼松动或臼柄松动 10例。所有病例均Ⅰ期翻修 ,采用骨水泥假体 ,有骨质缺损者同时植骨。 结果 术后无一例发生伤口感染、脱位和神经血管并发症 ,术后 6个月 ,患者可弃拐行走。随访 6~ 40个月 ,平均 2 3个月 ,患者髋关节功能良好 ,Harris评分由术前 3 5 .0分提高至术后 88.5分。 结论 假体松动是人工关节翻修术的主要原因。在翻修假体的选择上 ,骨水泥假体主要适用于老年骨质疏松患者、需长段异体骨复合人工假体患者、非骨水泥假体翻修失败患者及关节感染需在翻修术中使用抗生素骨水泥患者。翻修手术对手术技巧和手术设备要求较高 ,术前计划必不可少

The occurrence of prosthetic joint infection depends mainly on the status of the body, and the number and toxicity of bacteria. Two-stage revision arthroplasty is a common and effective procedure in controlling prosthetic joint infection. Besides, antibiotics is also indispensable during the procedure. However, the timing of two-stage revision arthroplasty, which is the intervals between the first stage and the second stage, has not come to an agreement yet.

人工关节置换术后由于机体全身和局部抵抗力降低 ,容易并发感染。在此过程中 ,细菌的数量、毒力和机体的抵抗力是三个最重要的因素 ,而细菌粘附是决定性起始步骤。Ⅱ期翻修术治疗是人工关节置换术后感染常用的治疗方法 ,即第一期对感染彻底清创 ,取出人工关节假体、骨水泥等异物 ,间隔一定时间后 ,第二期再植新假体。其主要优点在于感染清除率高 ,如在翻修间隔期使用暂时性关节替代系统如PROSTALAC等 ,再植新假体后关节功能可较好地保留。选择合适的抗生素以合适的方式给药是Ⅱ期翻修术治疗的重要组成部分 ,尤其是局部抗生素缓释系统的应用可显著提高感染清除率。但是 ,Ⅱ期翻修术治疗的时机即间隔期的长短尚无一致意见 ,原因在于缺乏实验依据和理论指导 ,根本在于尚未建立有效的动物模型。

Objective:To analyze the causes of revision total hip arthroplasty,and to evaluate the efficacy of total hip prostesis in cementless revision arthroplasty.Methods:Thirty-six patients,aged 35~78(mean 50)and 26 were male and 10 female,with 42 hips revised.The revision was undertaken,on average,at 6 years and 3 months(3 months~16 years)after the primary arthroplasty.The causes for revision surgery were:hip pain without loosening in 11 hips,infection in 2 hips,aseptic loosening in 27 hips,malposition of the stem prosthesis in 2 hips.Forty stems were revised with a tapered,rectangular grit-blasted titanium stem.Results:Except for the 8 patients,who underwent acetabular reconstruction with Schneider or Muller cups and bone graft,had to walk without loading on the surgery hip,all the patients could take walk by the help of crutchs with unconstrained loading 3 days postoperatively.The mean follow-up period was 22 months(range 6-66 months).The mean preoperative Harris' hip score(HHS)was 5-54(32.6) compared with the postoperative HHS of 56-98(87.5).Radiographic evaluation of the revised components demonstrated no evidence of loosening or subsidence,and could provide evident trabecular remodeling of both the graft and the host bone.No patients needed a second revision for any reason.Conclusion:Except for aseptic loosening,the most common cause of revision is hip pain reduced by unipolar and bipolar hip prosthesis.The results of revision arthroplasty with a tapered,rectangular grit-blasted titanium stem combined with a conical threaded or Schneider/Muller cups inserted without cement were excellent and encouraging at short-term follow-up.
