摘要
背景:人工全髋关节置换是目前成年人发育性髋关节发育不良疾病后期的终极治疗手段,但由于发育性髋关节发育不良的解剖结构变异复杂,使传统的全髋关节置换面临巨大挑战。目的:探讨在3D打印技术辅助下完成全髋关节置换治疗发育性髋关节发育不良的临床效果及安全性。方法:纳入2016年1月至2018年6月于沈阳医学院附属中心医院骨科接受初次人工全髋关节置换的20例发育性髋关节发育不良患者,随机分为2组,3D打印组10例在3D打印技术辅助下行全髋关节置换,传统置换组10例行传统全髋关节置换。记录2组患者的手术时间、出血量、并发症出现情况,术前及术后6个月对比Harris髋关节功能评分和疼痛目测类比评分。结果与结论:①与传统置换组相比,3D打印组手术时间及出血量均明显减少,差异均有显著性意义(P=0.000);②2组术后6个月目测类比评分、Harris髋关节功能评分均显著优于术前(P=0.000);③术后6个月,2组目测类比评分、Harris髋关节功能评分比较差异无显著性意义(P>0.05);④2组均无并发症发生;⑤说明3D打印技术辅助下行全髋关节置换与传统全髋关节置换治疗发育性髋关节发育不良均可取得较好的修复效果,但3D打印技术结合全髋关节置换的手术时间更短,出血量更少。
BACKGROUND: Total hip arthroplasty is the ultimate treatment for adult developmental dysplasia of the hip in the late stage of disease. However, due to the complicated anatomical variation of developmental dysplasia of the hip patients, the traditional total hip arthroplasty faces great challenges. OBJECTIVE: To explore the effectiveness and safety of three-dimensional (3D) printing technology-assisted total hip arthroplasty in the treatment of developmental dysplasia of the hip. METHODS: Twenty patients with developmental dysplasia of the hip, who underwent primary total hip arthroplasty in Department of Orthopedics, Central Hospital Affiliated to Shenyang Medical College from January 2016 to June 2018, were randomly divided into two groups. The 10 patients in the 3D printing group underwent total hip arthroplasty assisted by 3D printing technology, and 10 patients in the traditional operation group underwent traditional total hip arthroplasty. The operation time, blood loss, occurrence of complication, visual analog scale score and Harris hip joint function score before and 6 months after operation were recorded. RESULTS AND CONCLUSION:(1) Compared with the traditional operation group, the operation time and blood loss in the 3D printing group were significantly shortened, with significant differences (P=0.000).(2) Visual analog scale score and Harris hip joint function score were significantly higher at 6 months after operation than that before operation in both groups (P=0.000).(3) There was no significant difference in visual analog scale score and Harris hip joint function score between the two groups 6 months after operation (P > 0.05).(4) No complication occurred in both groups.(5) These results indicate that both 3D printing technology-assisted total hip arthroplasty and traditional total hip arthroplasty can achieve good clinical effects in the treatment of developmental dysplasia of the hip, but 3D printing technology combined with total hip arthroplasty has shorter operation time and less blood loss.
