To evaluate the use of hybrid total hip replacement (THR), using a cementless acetabular component and a cemented femoral component.
Prospective case series.
Client-owned dogs (n = 71).
Consecutive clinical cases that had hybrid THR were studied. Radiographic features, pain scores, and lameness scores were recorded pre- and postoperatively. Longer term outcome was assessed by owner questionnaire.
Hybrid THRs (n = 78) were performed in 71 dogs. Four cases (5%) had major postoperative complications; 3 were resolved after revision surgery, and 1 owner requested an explantation. No other major complications were identified on follow-up radiographs (67 THR) at 12 weeks. On clinical follow up (77 THR) at 4 weeks, lameness had improved in 68, was unchanged in 8, and was worse in 1. Pain had decreased in 72, was unchanged in 4, and was worse in 1. At 12 weeks (69 THR) compared with preoperative status, lameness had improved in 67 and was unchanged in 2. Pain had improved in 68 and was unchanged in 1. Longer term follow-up (mean, 16 months) was available for all hips. No further complications were reported. Owner satisfaction was good for 76 THRs and reasonable for 2.
Hybrid THR can be performed successfully with a low complication rate and represents an alternative to either entirely cemented or cementless implantation.
评估使用非骨水泥髋臼组件和骨水泥股骨组件的混合全髋关节置换术（THR）的应用情况。
前瞻性病例系列研究。
宠物犬（n = 71）。
对连续接受混合THR的临床病例进行研究。记录术前和术后的影像学特征、疼痛评分和跛行评分。通过主人问卷调查评估长期结果。
71只犬接受了78例混合THR。4例（5%）出现严重术后并发症；3例经翻修手术后得到解决，1位主人要求取出植入物。在12周时的随访X光片（67例THR）上未发现其他严重并发症。在4周时的临床随访（77例THR）中，68例跛行情况改善，8例无变化，1例恶化。72例疼痛减轻，4例无变化，1例恶化。与术前状态相比，在12周时（69例THR），67例跛行情况改善，2例无变化。68例疼痛改善，1例无变化。所有髋关节均有更长时间的随访（平均16个月）。未报告进一步的并发症。76例THR的主人满意度良好，2例满意度一般。
混合THR可以成功实施，并发症发生率低，是全骨水泥或非骨水泥植入的一种替代方案。
