摘要:


文题释义:

髋关节翻修术:髋关节置换是一种把人工设计的关节假体置入体内以代替病变髋关节的手术技术,置入的关节假体具有一定的寿命,根据不同情况有不同的生存周期。医生将第1次人工关节置换术称为初次置换,把同一关节的第二次置换称为翻修术。翻修常见的原因有:机械性松动、感染、骨折、人工关节不稳定、磨损、骨溶解、假体断裂等。翻修的部位有单纯髋臼侧、单纯股骨侧和全髋关节翻修。
髋臼骨缺损的Paprosky分型:PAPROSKY教授于1994年提出髋臼骨缺损分型。Ⅰ型:髋臼缘无骨缺损或假体移位;Ⅱ型:髋臼缘有缺损,但起支撑作用的髋臼柱完整,假体向上内侧或上外侧移位小于2 cm(Ⅱa型指旋转中心上移< 3 cm,髋臼顶部结构完整;Ⅱb型指旋转中心出现上移及内移,髋臼上缘有缺损;Ⅱc型指旋转中心内移,髋臼内侧壁骨缺损);Ⅲ型:上方移位大于2 cm,坐骨和内壁缺损严重[Ⅲa型为Kohler线完整,假体30%-60%的支撑需植骨提供(骨缺损位置:10点到2点位置),Ⅲb型为Kohler线不完整,大于60%的假体支撑需植骨提供(骨缺损位置:9点到5点位置)]。

背景:随着接受人工全髋关节置换的患者越来越多,出现髋臼侧松动伴不同程度骨缺损的患者日趋增加,治疗方式有多种,包括结构植骨、颗粒植骨加钛网重建、钽金属垫块重建、Jumbo杯、Cup-Cage技术等。
目的:总结个性化生物臼杯翻修全髋关节置换后髋臼侧松动的近期临床疗效,为髋关节翻修提供一种可行的方法。
方法:选择2017年3月至2019年3月解放军第九八九医院平顶山医疗区收治的全髋关节置换后髋臼侧松动11例患者,其中男7例,女4例;年龄55-71岁,均采用个性化生物臼杯进行髋臼侧翻修并进行3年随访,记录术前和末次随访的髋关节Harris评分、目测类比评分和双下肢绝对长度差,观察X射线片表现,评估髋关节功能恢复状态和骨长入情况。
结果与结论:①所有患者均由同一医生主刀完成,随访满3年,无丢失病例,其中1例出现坐骨神经症状,口服甲钴胺片,6个月恢复;②末次随访的髋关节Harris评分、目测类比评分和双下肢绝对长度差与术前比较,差异有显著性意义(P < 0.05);③末次随访X射线片显示有良好的骨长入;④结果表明,应用个性化生物臼杯翻修全髋关节置换后髋臼侧松动可获得假体的初始稳定性、恢复理想的关节功能和较好的骨长入,为髋关节翻修提供一种可行的方法。

Abstract: BACKGROUND: More and more patients received the total hip arthroplasty, and the acetabular loosening occurrence is increasing day and day. Commonly used operative methods include structural bone graft, morselized bone grafting and titanium mesh reconstruction, tantalum metal pads reconstruction, Jumbo cup and Cup-Cage technology.  
OBJECTIVE: To summarize the clinical effect of the individual biological acetabular cup application in acetabular loosening after total hip arthroplasty and supply a feasible method for the hip revision.
METHODS: Eleven patients with acetabular loosening after the total hip arthroplasty undergoing acetabular revision used individual biological acetabular cups admitted at Pingdingshan Medical District Second Department of Orthopedics, the 989 Hospital of Chinese People’s Liberation Army Joint Logistics Support Force between March 2017 and March 2019 were included in this study. Of them, there were 7 men and 4 women, with the age of 55-71 years. The individual biological cups were used in the hip revision surgery and followed up for 3 years. Harris score, visual analogue scale score and absolute length difference of both lower limbs were recorded preoperatively and at final follow-up. X-ray films were observed to assess hip functional recovery and bone ingrowth.  
RESULTS AND CONCLUSION: (1) All patients were underdone by the same doctor, followed up for 3 years and none lost. Among them, one case had symptoms of sciatic nerve, orally took mecobalamin tablets and recovered in 6 months. (2) Harris score, visual analogue scale score and absolute length difference of both lower limbs were significantly improved during the last follow-up (P < 0.05). (3) Last X-ray films showed good bone ingrowth. (4) These results imply that the individual biological acetabular cup application in acetabular loosening after total hip joint arthroplasty can restore the primary stability, restore ideal joint function and better bone ingrowth, and provide a feasible method for hip revision.

Key words: biological acetabular cup, revision, individual, bone defect, total hip arthroplasty, hip function recovery
