Background

Surgical management of periacetabular bone metastases is challenging. The Harrington Plus reconstruction is a modification of the original Harrington rod technique. An intrapelvic suprapectineal plate is used, with the aim of reconstructing a disrupted anterior column and reducing the risk of failure in cases where there is extensive medial bone loss.

Methods

A retrospective review of the 13 patients who have undergone the Harrington Plus procedure to date was performed. Mobility status, EQ5D and Oxford Hip scores were assessed.

Results

There was a significant improvement in mobility status, EQ5D and Oxford Hip Scores at 6 months postoperatively (p < 0.05). Two patients returned to theatre for debridement of infection. There were no postoperative dislocations, cup medialisation or cases of loosening of the prosthesis. No patient required revision arthroplasty surgery.

Conclusion

The Harrington Plus procedure produces a reliable construct that allows patients with extensive periacetabular metastatic defects to fully weight-bear. Careful patient selection and multidisciplinary management is essential.

Harrington plus 重建骨盆和髋臼转移

背景

髋臼周围骨转移的手术治疗具有挑战性。Harrington Plus 重建是对原始 Harrington 棒技术的修改。使用骨盆内耻骨上骨板，目的是重建破坏的前柱，并在出现大量内侧骨丢失的情况下降低失败的风险。

方法

对迄今为止接受 Harrington Plus 手术的 13 名患者进行了回顾性研究。评估了活动状态、EQ5D 和牛津髋关节评分。

结果

术后 6 个月时，活动状态、EQ5D 和牛津髋关节评分有显着改善（p < 0.05）。两名患者返回手术室进行感染清创。没有术后脱位、杯子内侧或假体松动的情况。没有患者需要翻修关节成形术。

结论

Harrington Plus 手术产生了一种可靠的结构，使患有广泛髋臼周围转移性缺损的患者能够完全负重。仔细的患者选择和多学科管理是必不可少的。
