A significant rim defect encountered during revision surgery can make stable cementless cup fixation difficult. One approach to this problem is to medialize the acetabular cup to improve the degree of rim contact. In this study, we investigate this technique, termed the medial protrusio technique, for acetabular fixation in revision hip arthroplasty. A retrospective review of 25 patients (25 hips) who underwent medialization was performed. Clinical and radiographic evaluation was performed. At an average follow-up of 6.6 years, the overall patient function and satisfaction were good to excellent, with a mean Harris hip score of 85.2. This demonstrates that the medial protrusio technique can be a valuable option in addressing acetabular cup failure.
在翻修手术中遇到明显的边缘缺损会使非骨水泥杯固定变得困难。解决这个问题的一种方法是将髋臼杯向内侧移位，以提高边缘接触的程度。在这项研究中，我们研究了这种技术，称为髋臼内侧移位技术，用于翻修髋关节置换术中的髋臼固定。对 25 名（25 髋）接受内侧化的患者进行了回顾性研究。进行了临床和影像学评估。平均随访 6.6 年后，患者的整体功能和满意度良好至优秀，平均 Harris 髋关节评分为 85.2。这表明髋臼内侧移位技术在处理髋臼杯失败方面是一种有价值的选择。
