Although bone anchors can help to repair soft tissues to bone, they are not without potential problems. A group of 214 consecutive total hip arthroplasties performed through a direct lateral approach using bone anchors for abductor mechanism repair was evaluated at 8 to 12 (mean 10.2) years. Complications included anchor migration from the bone in 18 (8.4%) patients, a unique pattern of symptomatic progressive osteolysis involving the lateral aspect of the greater trochanter in 8 (3.7%) patients, and pathological fracture of the greater trochanter in 1 (0.5%) patient. Three patients (1.4%) with trochanteric osteolysis required surgical intervention including removal of the anchors, debridement and reattachment of the abductor mechanism and repair of a pathological fracture. Considering these complications, as well as the significant cost, bone anchors are not recommended for abductor mechanism repair when using the direct lateral approach for total hip arthroplasty.
尽管骨锚有助于将软组织修复至骨骼，但它们并非没有潜在问题。对一组连续214例通过直接外侧入路进行全髋关节置换术并使用骨锚修复外展肌机制的患者进行了8至12年（平均10.2年）的评估。并发症包括18例（8.4%）患者的骨锚从骨骼中移位，8例（3.7%）患者出现一种独特的有症状的进行性骨质溶解模式，累及大转子外侧，1例（0.5%）患者发生大转子病理性骨折。3例（1.4%）发生转子骨溶解的患者需要手术干预，包括取出骨锚、清创、重新附着外展肌机制以及修复病理性骨折。考虑到这些并发症以及高昂的成本，在采用直接外侧入路进行全髋关节置换术时，不建议使用骨锚修复外展肌机制。
