As surgeons' comfort with the direct anterior approach (DAA) for total hip arthroplasty continues to increase, there is a growing interest in performing complex surgeries through this approach. Acetabular bone loss and/or pelvic discontinuity in the primary or revision setting often requires specialized implants such as a cup-cage construct. We describe our surgical technique for implanting modified cup-half cages through the DAA and show 2 case examples of how this technique was utilized in the setting of complex acetabular bone loss. In our experience, this is an effective method for complex total hip arthroplasty, with the potential added benefits of the DAA of reduced soft-tissue dissection, direct measurement of leg length, and ease of fluoroscopic navigation for implant positioning.
随着外科医生对全髋关节置换术直接前路（DAA）的操作熟练度不断提高，人们越来越有兴趣通过这种入路进行复杂手术。初次或翻修手术中髋臼骨丢失和/或骨盆连续性中断通常需要特殊植入物，如髋臼杯-骨笼结构。我们描述了通过DAA植入改良半髋臼杯骨笼的手术技术，并展示了2个在复杂髋臼骨丢失情况下应用该技术的病例。根据我们的经验，这是复杂全髋关节置换术的一种有效方法，具有DAA的潜在额外益处，即减少软组织剥离、直接测量腿长以及便于在透视引导下进行植入物定位。
