A 35-year-old female patient with acetabular dysplasia underwent a Pol Le Cœur triple pelvic osteotomy (TPO). Twenty-eight years later, she presented with painful end-stage hip osteoarthritis and underwent total hip arthroplasty (THA). A press-fit cementless acetabular cup and a cemented straight femoral stem were implanted without complications. At 13-year follow-up, hip radiographs revealed no signs of prothesis instability and no signs of implant loosening. TPO may not completely prevent the progression of hip osteoarthritis. In this case, the patient developed progressive end-stage osteoarthritis 28 years after the osteotomy, requiring THA. Pol Le Cœur TPO is a viable treatment option for symptomatic acetabular dysplasia in younger adults with low-grade osteoarthritis, effectively delaying hip prosthesis implantation. Hybrid THA after TPO can yield very satisfactory clinical and radiographic outcomes at mid-term follow-up.
一名35岁髋臼发育不良的女性患者接受了波尔·勒科尔三联骨盆截骨术（TPO）。28年后，她出现疼痛性终末期髋骨关节炎并接受了全髋关节置换术（THA）。植入了压配式非骨水泥髋臼杯和骨水泥固定的直柄股骨柄，未出现并发症。在13年的随访中，髋关节X线片显示没有假体不稳定迹象，也没有植入物松动迹象。TPO可能无法完全阻止髋骨关节炎的进展。在本病例中，患者在截骨术后28年出现进行性终末期骨关节炎，需要进行THA。波尔·勒科尔TPO是年轻成人轻度骨关节炎有症状髋臼发育不良的一种可行治疗选择，可有效延迟髋关节假体植入。TPO术后的混合THA在中期随访时可产生非常令人满意的临床和影像学结果。
