摘要
Background: Trabecular metal augments (TMAs) have been extensively used in revision total hip arthroplasty (THA) to address acetabular bone defects. However, limited data exists regarding TMA utilization during primary THA. This study aims to assess the clinical and radiographic outcomes of TMAs used during primary THA. Methods: A single-institution retrospective case series of primary THA patients treated with TMA between 2010 and 2019 was performed. Patient demographics, complications, and revisions were recorded. Cup position, center of rotation, leg length, and radiolucent lines were assessed radiographically. The Kaplan-Meier method was used to compute implant survivorship. Results: Twenty-six patients (30 hips) were included with average age of 52.6 +/- 15.3 years (range: 22-78) and mean follow-up of 4.1 +/- 2.1 years (range: 2.0-8.9). Most TMAs were indicated for developmental dysplasia of the hip (n 1/4 18; 60.0%). On average, hip center of rotation was lowered 1.5 +/- 1.3 cm and lateralized 1.2 +/- 1.5 cm, while leg length and global offset were increased by 2.4 +/- 1.2 cm and 0.4 +/- 1.0 cm, respectively. At final follow-up, 3 hips (10.0%) required revision: one (3.3%) for aseptic loosening and 2 (6.7%) for instability. No patients had progressive radiolucent lines at final follow-up. Five-year survival with aseptic loosening and all-cause revision as endpoints was 100% (95% confidence interval: 90.0%100.0%) and 92.1% (95% confidence interval: 81.3%-100.0%), respectively. One patient required revision for aseptic loosening after the 5-year mark. Conclusions: Trabecular metal augmentation during primary THA demonstrates satisfactory early to midterm outcomes. TMA is a viable option for complex primary THA when bone loss is encountered or secondary support is required. Level of Evidence: Level IV. (c) 2024 The Authors.
