    摘要:

    [目的] 介绍3D打印个性化假体在髋关节翻修置换术中治疗复杂髋臼缺损的手术技术及临床疗效。[方法] 应用个性化髋臼假体对11例复杂髋臼缺损患者实施髋关节翻修术,行髋关节后外侧切口,充分显露髋臼,通过螺钉多维度固定髋臼假体并重建其解剖对位关系。 [结果] 11例患者均顺利完成手术,无严重并发症。随访36个月。末次随访时,患髋的疼痛及功能均较术前显著改善,VAS疼痛评分及髋关节功能Harris评分平均为(0.82±0.40)及(86.82±2.48)。术后36月定制髋臼假体的生存率达到100%。[结论] 3D打印个性化假体在髋翻修术中治疗复杂髋臼缺损的临床疗效良好。

    Abstract:

    [Objective] To introduce the surgical technique and clinical effect of 3D printing personalized prosthesis in the treatment of complex acetabular defects in hips revision. [Method] Eleven patients with complex acetabular defects underwent hip revision with personalized acetabular prosthesis. The posterior lateral incision of the hip was performed to fully expose the acetabulum. The acetabular prosthesis was fixed in multiple dimensions by long screws and its anatomical alignment was reconstructed. [Result] All 11 patients completed the operation successfully without serious complications. The patients were followed up for 36 months. At the last follow-up, the pain and function of the hip were significantly improved compared with those before operation. The average VAS pain score and Harris score of hip function were (0.82±0.40) and (86.82±2.48). Survival rate of pterygoid acetabular prosthesis was 100% within 36 months. [Conclusion] The clinical effect of 3D printing personalized prosthesis in the treatment of complex acetabular defects in hip revision surgery is good.
