Total hip arthroplasty (THA) in the adolescent patient has historically shown relatively poor survivorship. This study reports the results of THA in young patients using contemporary ceramic bearings. Twenty-four THAs were performed using ceramic bearing surfaces in patients 20 years old or younger (mean, 16.4; range, 12-20). Average follow-up was 52 months (range, 25-123 months). The survival rate was 96%, with 1 revision for a loose acetabular component. Other complications included a peroneal nerve palsy that resolved and 2 dislocations in 1 patient. Postoperatively, the Modified Harris Hip Score mean was 93.4 (range, 66-100). This study shows promising results at short-term to midterm follow-up in very young patients who undergo THA using ceramic-on-ceramic components.
全髋关节置换术（THA）在青少年患者中的历史生存率相对较低。本研究报告了使用当代陶瓷轴承进行年轻患者 THA 的结果。24 例 20 岁或以下（平均年龄 16.4 岁；范围 12-20 岁）的患者接受了陶瓷轴承表面的 THA。平均随访时间为 52 个月（范围 25-123 个月）。生存率为 96%，1 例髋臼组件松动需要翻修。其他并发症包括腓总神经麻痹（已缓解）和 1 例脱位。术后，改良 Harris 髋关节评分平均为 93.4（范围 66-100）。这项研究在使用陶瓷对陶瓷组件进行 THA 的非常年轻的患者中，在短期至中期随访中显示出了有前途的结果。
