INTRODUCTION
The custom triflange acetabular implant (CTAI) has been described to address catastrophic pelvic osteolysis, but long-term outcome data is scarce.
METHODS
Revision-free survivorship after revision THA with a CTAI was retrospectively reviewed in seven patients.
RESULTS
Mean and median follow-up time were 7.39 (1.61-16.8) years and 7.50 years, respectively. Revision-free survivorship was 85.7% (6/7). One patient underwent revision for recurrent dislocations. All patients were able to ambulate at recent follow-up- 2/7 without assistance.
CONCLUSIONS
The CTAI is a viable option for patients with catastrophic pelvic osteolysis. There is a high complication rate, but the incidence of revision is low.
引言
定制三翼髋臼植入物（CTAI）已被描述用于治疗灾难性骨盆骨溶解，但长期结果数据稀缺。
方法
对7例接受CTAI翻修全髋关节置换术（THA）后的无翻修生存率进行回顾性研究。
结果
平均随访时间和中位随访时间分别为7.39（1.61 - 16.8）年和7.50年。无翻修生存率为85.7%（6/7）。1例患者因复发性脱位接受翻修手术。所有患者在最近一次随访时均能行走，其中2/7无需辅助。
结论
CTAI是治疗灾难性骨盆骨溶解患者的可行选择。并发症发生率高，但翻修率低。
