Achondroplasia (ACH) is the most common form of hereditary dwarfism and presents with multiple musculoskeletal anomalies but is not normally associated with premature hip arthritis. Developmental dysplasia of the hip (DDH) is a spectrum of disease resulting in shallow acetabular depth and a propensity for chronic femoral subluxation or dislocation; it is among the most common causes of premature arthritis. This case report describes the diagnosis of symptomatic DDH in a patient with ACH and highlights difficulties of primary total hip arthroplasty (THA) as a treatment option. Intraoperative radiographic imaging is advised to ensure proper prosthesis placement. Femoral osteotomy may aid visualization, reduction, and avoidance of soft tissue injury. Concomitant ACH and DDH is a challenging problem that can be successfully treated with modified THA.
软骨发育不全（ACH）是遗传性侏儒症最常见的形式，表现为多种肌肉骨骼异常，但通常与髋关节过早关节炎无关。发育性髋关节发育不良（DDH）是一系列疾病，会导致髋臼深度变浅以及慢性股骨半脱位或脱位的倾向；它是过早关节炎最常见的原因之一。本病例报告描述了一名ACH患者出现症状性DDH的诊断，并强调了初次全髋关节置换术（THA）作为一种治疗选择的困难。建议术中进行放射影像学检查以确保假体正确放置。股骨截骨术可能有助于改善视野、复位以及避免软组织损伤。ACH和DDH并存是一个具有挑战性的问题，可通过改良的THA成功治疗。
