Abstract

Introduction: Severe acetabular bone defects can pose challenges in revision total hip replacement. The use of structural allografts and various sizes of grain allografts has been proposed as an alternative surgical technique for treating Paprosky type 3 acetabular defects. This study aimed to evaluate the long-term outcomes and potential complications associated with this approach.

Methods: A retrospective review was performed on 102 hip reconstructions in patients with major acetabular bone loss, including 81 cases of type 3A and 21 cases of type 3B according to Paprosky's classification. Surgical procedures involved the use of structural allografts and various sizes of grain allografts in both reinforcement ring group and cementless cups group.

Results: At a mean follow-up of 82.75 months, 76% of hips had no complications, while The others experienced pain changes in the cup position, post-operative dislocations, and infections. The mean pre-operative Modified Harris Hip Score improved in both groups at the last follow-up.

Conclusion: The use of structural allografts and various sizes of grain allografts for treating type 3 acetabular defects in revision total hip replacement showed promising long-term outcomes and a low rate of complications. Level of Evidence IV; Retrospective Case Series.

在帕普罗斯基 3 型中使用不同大小的谷粒异体移植的长期效果。

导言：严重的髋臼骨缺损会给翻修全髋关节置换术带来挑战。使用结构性异体移植和不同大小的颗粒异体移植作为治疗Paprosky 3型髋臼缺损的替代手术技术已被提出。本研究旨在评估这种方法的长期疗效和潜在并发症：方法：对102例髋臼骨严重缺损患者的髋关节重建进行了回顾性研究，根据Paprosky的分类，其中81例为3A型，21例为3B型。手术过程中，加固环组和无骨水泥髋臼杯组都使用了结构性异体移植物和不同大小的颗粒异体移植物：结果：在平均 82.75 个月的随访中，76% 的髋关节没有出现并发症，而其他髋关节则出现了髋臼杯位置疼痛变化、术后脱位和感染。在最后一次随访中，两组患者术前的平均修正哈里斯髋关节评分均有所改善：结论：在翻修全髋关节置换术中使用结构性异体移植物和不同大小的颗粒异体移植物治疗3型髋臼缺损显示出良好的长期疗效和较低的并发症发生率。证据级别IV；回顾性病例系列。
