We report our early experience in acetabular reconstruction for significant bone loss and pelvic discontinuity using custom triflange acetabular components.
Retrospective consecutive review of all patients treated at our specialist tertiary unit with significant acetabular defects () and pelvic discontinuity who were reconstructed with custom triflange implants. The primary outcomes were radiographic failure and complications.
17 patients (17 hips) were included; 3 males/14 females with a mean age of 72 years (range 61-83). The average follow-up was 3.6 years (2-7 years). Bony defects were 3B in 13/17 hips (76%) with pelvic discontinuity encountered in the majority of cases 15/17 hips (88%) and intra-pelvic failed components in 11/17 (64%). At final follow up, no radiographic failures were observed although three patients developed complications (17.6%); haematoma requiring washout out; intra-operative ilium fracture; and recurrent dislocation in one patient.
Our experience suggest that acceptable outcomes can be achieved with custom implants for this group of challenging patients, although longer follow up is needed to monitor future implants' failure.
我们报告使用定制三翼髋臼组件进行髋臼重建以治疗严重骨丢失和骨盆连续性中断的早期经验。
对在我们的专科三级医疗单位接受治疗的所有髋臼严重缺损（）和骨盆连续性中断且使用定制三翼植入物进行重建的患者进行回顾性连续分析。主要结局指标为影像学失败和并发症。
纳入17例患者（17髋）；男性3例/女性14例，平均年龄72岁（范围61 - 83岁）。平均随访3.6年（2 - 7年）。13/17髋（76%）存在3B型骨缺损，大多数病例（15/17髋，88%）出现骨盆连续性中断，11/17（64%）存在盆腔内植入物失败。末次随访时，虽有3例患者出现并发症（17.6%），但未观察到影像学失败；血肿需冲洗；术中髂骨骨折；1例患者复发性脱位。
我们的经验表明，对于这组具有挑战性的患者，定制植入物可取得可接受的结果，尽管需要更长时间的随访来监测未来植入物的失败情况。
