摘要:


文题释义:

髋关节翻修:人工髋关节置换后由于假体磨损、感染、创伤等原因,导致人工关节配件发生松动移位,引起髋关节再次出现疼痛症状和功能受限,影响患者的生活质量及工作能力。为了缓解疼痛、重建髋关节功能,需再次手术将原来松动的人工髋关节配件取出,安装新的人工髋关节假体。
髋臼骨缺损的Paprosky分型:Ⅰ型,髋臼骨缺损极少,旋转中心无明显移位,髋臼前后柱及顶部承重结构完整;Ⅱ型,髋臼中等骨缺损,前后柱完整,髋臼顶部及内侧壁存在骨丢失,仍能为髋臼杯提供足够支撑(ⅡA型旋转中心上移< 3 cm,髋臼顶部结构完整,ⅡB型髋臼旋转中心发生上移及内移,骨缺损位于髋臼上缘;ⅡC型髋臼旋转中心发生内移,骨缺损位于髋臼内侧);Ⅲ型,髋臼存在严重骨缺损,无法为髋臼杯提供足够支撑,并常伴有骨盆不连续(ⅢA型旋转中心侧上方移位,Kohler线完整,骨缺损在髋臼10点到2点位置;ⅢB型旋转中心内后移位,Kohler线不完整,骨缺损在髋臼9点到5点位置)。

摘要
背景:髋臼顶部骨缺损是人工髋翻修过程中常见而又复杂的挑战,因为该部位的骨缺损会影响翻修术中髋臼杯的初始稳定性以及中长期稳定性。
目的:评估髋臼阻挡螺钉联合颗粒打压植骨技术重建髋关节翻修过程中髋臼顶部骨缺损的效果。
方法:选择2018年3月至2022年12月佛山市中医院收治的11例人工全髋关节置换后髋臼杯松动合并髋臼顶部Paprosky ⅢA型骨缺损患者,均采用髋臼阻挡螺钉联合颗粒打压植骨技术重建骨缺损。记录并对比翻修前和翻修后末次随访的髋关节Harris评分、满意度评分以及双下肢长度差;通过X射线片评估翻修后髋臼杯以及髋臼阻挡螺钉的状态。
结果与结论:①11例患者随访时间为20-72个月;②截止到术后末次随访,所有患者的髋关节Harris评分、满意度评分以及双下肢长度差与翻修术前比较,均有显著改善(P < 0.001);③末次随访X射线片提示所有患者髋臼杯周缘都有良好的骨长入,没有髋臼杯再次松动的情况发生;④所有髋臼杯阻挡螺钉在术后末次随访X射线片上均没有发生移位或者断裂;⑤结果表明,髋臼阻挡螺钉联合颗粒打压植骨是重建髋关节翻修过程中髋臼顶部骨缺损一种简便而有效的技术,不仅有助于人工髋关节翻修过程中髋臼杯初始稳定性的实现,也有利于加强髋臼杯的中远期稳定性。

Abstract: BACKGROUND: Bone defect at the top of acetabulum during revision total hip arthroplasty is a common and complex challenge, because it often affects the initial and mid-term to long-term stability of the acetabular cup during revision surgery. 
OBJECTIVE: To evaluate the effect of bone defect reconstruction at the top of acetabulum with cup blocking screws and impaction bone grafting during revision total hip arthroplasty.  
METHODS: Between March 2018 and December 2022, 11 patients with acetabular cup loosening and acetabular top Paprosky IIIA bone defect after total hip arthroplasty in Foshan Hospital of Traditional Chinese Medicine were selected. All patients were reconstructed with acetabular blocking screw combined with particle impaction bone grafting technology. Harris score, satisfaction score, and leg length discrepancy were recorded and compared before revision and at the final follow-up after revision. X-ray films were observed to evaluate the condition of acetabular cups and blocking screws.
RESULTS AND CONCLUSION: (1) All 11 patients were followed up for 20-72 months. (2) Harris score, satisfaction score, and leg length discrepancy were significantly improved at the last follow-up (P < 0.001). (3) Last postoperative X-ray films showed good bone ingrowth around the cup and no acetabular loosening in all patients. (4) No cup blocking screw was found to be broken or displaced in last postoperative X-ray films. (5) All these results imply that cup blocking screws combined with impaction particulate bone grafting is a simple and reliable technique in reconstructing the bone defect at the top of acetabulum during revision. This technique can not only simplify the achievement of initial stability during revision, but can also strengthen the mid-term to long-term stability of the cup.
