Abstract

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.
