The reconstruction of large acetabular defects in revision hip arthroplasty represents a challenge to the surgeon and increases the complexity of the case. There are different options to overcome the problem of acetabular deficiency. In the elderly low demand patients, the main objective of revision surgery is to provide pain relief, allow immediate full weight bearing, and an early return to function.
This article presents our experience in acetabular revision surgery using a novel technique of two stage cementation and screw augmentation in low demand patients. We report on the surgical technique and present the early results in 10 patients.
There were 6 females and 4 males with average age of 83.8 years. Patients were followed up for an average of 18.1 months. All patients were pain free and full weight bearing at the time of the final follow up with radiographs showing maintenance of implant position. None of the patients underwent revision surgery and there were no radiographic signs of failure detected in the early follow-up period.
This is a suitable technique in the management of large acetabular defects in revision hip arthroplasty, especially in the low demand patient population. It is a simple cost-effective technique that reduces the complexity of the acetabular revision, operative time, and morbidity associated with prolonged complex revision surgery.
髋关节翻修术中大髋臼缺损的重建对外科医生来说是一项挑战，会增加手术的复杂性。有多种方法可解决髋臼缺损问题。对于需求较低的老年患者，翻修手术的主要目标是缓解疼痛、允许立即完全负重并早日恢复功能。
本文介绍了我们在需求较低的患者中使用两阶段骨水泥固定和螺钉增强新技术进行髋臼翻修手术的经验。我们报告了手术技术并展示了10例患者的早期结果。
患者中有6名女性和4名男性，平均年龄为83.8岁。患者平均随访18.1个月。在最后一次随访时，所有患者均无疼痛且完全负重，X线片显示植入物位置保持良好。没有患者接受翻修手术，在早期随访期间未发现X线片上的失败迹象。
这是一种适用于髋关节翻修术中大髋臼缺损处理的技术，尤其适用于需求较低的患者群体。它是一种简单且经济有效的技术，可降低髋臼翻修的复杂性、手术时间以及与长时间复杂翻修手术相关的发病率。
