Anatomic femoral components are optimized for primary osteoarthritis, and few long-term results for their use are available for developmental dysplasia of the hip (DDH). We reviewed 135 uncemented total hip arthroplasties in which an anatomic femoral component was used in 106 patients with DDH, excluding femurs with neck-shaft angles of >160° and femurs with anteversion of >50°. The mean age of patients at surgery was 49.4 years (range, 33-66 years), and the mean duration of follow-up was 13.5 years (range, 10-18 years). No osteoporotic femurs were included in our study group. Despite 18 acetabular revisions, no femoral component was removed for any reason. No femoral loosening was seen at the final follow-up examination. An anatomic femoral component with circumferential porous coating can produce good clinical and radiologic findings in young patients with good bone quality who have DDH without excessive femoral deformity.
解剖型股骨假体针对原发性骨关节炎进行了优化,而对于发育性髋关节发育不良(DDH)患者使用解剖型股骨假体的长期结果,目前相关数据较少。我们回顾了 106 例 DDH 患者的 135 例非骨水泥全髋关节置换术,排除了颈干角>160°和前倾角>50°的股骨。手术时患者的平均年龄为 49.4 岁(范围 33-66 岁),平均随访时间为 13.5 年(范围 10-18 年)。我们的研究组中不包括骨质疏松性股骨。尽管进行了 18 次髋臼翻修,但没有因任何原因取出股骨假体。在最后一次随访检查时,未发现股骨松动。对于骨质量良好、无明显股骨畸形的年轻 DDH 患者,使用具有环形多孔涂层的解剖型股骨假体可以获得良好的临床和影像学结果。
