Acetabular fractures are accompanied by complications such as post-traumatic osteoarthritis (OA) of the hip and avascular necrosis (AVN) of the femoral head. The aim of the study was to evaluate improvement of life quality and functional recovery after total hip arthroplasty (THA) in patients with post-traumatic OA and AVN.
We retrospectively reviewed 23 patients with post-traumatic OA of the hip and AVN of the femoral head who undergone THA, out of 63 patients who were previously surgically treated for acetabular fractures. Final functional outcomes are defined according to the Merle d'Aubigné score, and the pain intensity according to VAS from 0 to 10.
Out of 63 patients with acetabular fractures from 2008 to 2018, we analyzed 23 (36.5%) patients, with an average age of 51.5 ± 13.8 years, who required THA due to post-traumatic OA and AVN of the femoral head. THA was done after the average of 4.28 years (range 1 to 8) from previous acetabular osteosynthesis. According to Merle d'Aubigné score, final functional outcomes before THA were moderate with average points of 4.86 (4-6). Post-THA final functional outcomes were excellent with an average point of 10.04 (10-12) (p < 0.001). The ratio of VAS before and after THA was 9.04:1.95(p < 0.001).
THA is a method which gives the best results in the treatment of post-traumatic OA of the hip and AVN of the femoral head after previous osteosynthesis of the acetabular fracture. After THA, life quality and functional status of a patient are significantly improved.
髋臼骨折常伴有创伤后髋关节骨关节炎（OA）和股骨头缺血性坏死（AVN）等并发症。本研究旨在评估创伤后 OA 和 AVN 患者行全髋关节置换术（THA）后生活质量和功能恢复的改善情况。
我们回顾性分析了 2008 年至 2018 年期间 63 例髋臼骨折患者，其中 23 例（36.5%）患者因创伤后髋关节 OA 和股骨头 AVN 接受了 THA。最终功能结果根据 Merle d'Aubigné 评分定义，疼痛强度根据 0 到 10 的视觉模拟评分（VAS）进行评估。
在 2008 年至 2018 年期间 63 例髋臼骨折患者中，我们分析了 23 例（36.5%）患者，平均年龄为 51.5±13.8 岁，由于创伤后髋关节 OA 和股骨头 AVN 需要接受 THA。THA 是在髋臼骨合成术平均 4.28 年后（1-8 年）进行的。根据 Merle d'Aubigné 评分，THA 前的最终功能结果为中度，平均得分为 4.86（4-6）。THA 后的最终功能结果为优秀，平均得分为 10.04（10-12）（p<0.001）。THA 前后 VAS 的比值为 9.04:1.95（p<0.001）。
THA 是治疗髋臼骨折骨合成术后创伤后髋关节 OA 和股骨头 AVN 的最佳方法。THA 后，患者的生活质量和功能状态显著改善。
