【摘要】：【目的】探讨Ribbed解剖型生物固定股骨柄假体(Ribbed柄)的设计特征及其与临床疗效关系。【方法】对2010年3月至2012年3月因髋关节疾病,在我院采用Ribbed柄行全髋关节置换(THA)术的患者进行回顾性分析。共获完整资料者52例(52髋),男20例,女32例;手术时年龄22~78岁,平均59岁。随访时间2~4年,平均3.1年。评估手术前后Harris评分、术后大腿疼痛率、术中骨折发生率、切口愈合情况、脱位及翻修等。影像学重点评估股骨柄髓腔充填率、股骨柄假体下沉、假体周围放射学透亮线、骨长入、应力遮挡及骨溶解等。【结果】术中股骨骨折发生率5.8%;所有切口均一期愈合;无髋关节脱位及翻修病例;大腿疼痛率为5.8%,均于术后1年消失;末次随访时,平均Harris评分由术前48分提高到末次随访时96分。术后X线片示所有患者股骨髓腔充填满意,平均充填率:正位片上干骺端、中段和远端分别为91%、88%和86%,侧位片上干骺端、中段和远端分别为88%、85%和81%;末次随访时,49髋(92.4%)为稳定性骨长入固定,3髋为稳定性纤维长入固定,股骨侧及髋臼侧假体周围均未见骨溶解;5髋(9.6%)发生股骨柄假体下沉,但均2 mm;所有患者均出现不同程度的应力遮挡现象,其中1度31髋、2度19髋、3度2髋,无4度应力遮挡发生。【结论】Ribbed柄设计符合生物学固定要求,术后能够获得生物学骨长入稳定,可取得满意的临床疗效和影像学结果。
[Abstract]:[Objective] to investigate the Ribbed anatomical biological fixation of femoral stem prosthesis (Ribbed handle) the design features and its relationship with clinical efficacy. [method] on March 2010 to March 2012 for hip disease in our hospital with Ribbed handle for total hip arthroplasty (THA) patients were retrospectively analyzed. 52 cases received complete data (52 hips), male 20 cases, female 32 cases; surgery at age 22~78 years old, average 59 years old. The follow-up time was 2~4 years, average 3.1 years. The evaluation of the Harris score before and after surgery, postoperative thigh pain rate, the incidence of fracture, wound healing, dislocation and revision. The imaging focus evaluation of femoral medullary cavity filling rate, femoral prosthesis subsidence, periprosthetic radiology radiolucent lines, bone ingrowth, stress shielding and osteolysis. [results] intraoperative femoral fractures occurred in 5.8%; all incisions healed; no dislocation of the hip and thigh pain rate revision cases; 涓，
