Injury to the acetabular triradiate physeal cartilage is a rare but potentially serious injury. When it occurs in young children acetabular growth may be delayed, leading to incongruency of the hip and subsequent subluxation. This series reviews 5 patients who sustained injury to the triradiate cartilage and subsequently developed acetabular dysplasia. The radiographic appearance of post-traumatic dysplasia is distinctly different than that of developmental dysplasia. In post-traumatic dysplasia the acetabular teardrop width and inner wall of the acetabulum is significantly increased with the femoral head being lateralized. Four patients have undergone acetabular reconstruction, with 3 patients having a periacetabular osteotomy and 1 having a Chiari osteotomy. The remaining patient with posttraumatic dysplasia has severe and symptomatic osteoarthritis and awaits a total hip replacement.
髋臼三辐射骨骺软骨损伤是一种罕见但可能严重的损伤。当它发生在幼儿身上时，髋臼生长可能会延迟，导致髋关节不协调并随后出现半脱位。本系列回顾了5例三辐射软骨损伤并随后发展为髋臼发育不良的患者。创伤后发育不良的影像学表现与发育性发育不良明显不同。在创伤后发育不良中，髋臼泪滴宽度和髋臼内壁显著增加，股骨头向外移位。4例患者接受了髋臼重建，3例患者进行了髋臼周围截骨术，1例进行了Chiari截骨术。其余患有创伤后发育不良的患者患有严重且有症状的骨关节炎，等待全髋关节置换。
