摘要:
目的：探讨3D打印技术在髋关节置换术中的应用。方法：对130例行髋关节置换术患者的临床资料进行回顾性分析，按照手术方法不同分为传统手术组（n=70）和3D打印组（n=60），比较两组手术情况、影像学指标、手术前后髋关节功能评分、下肢力线、并发症发生率。结果：3D打印组术中出血量少于传统手术组，手术时间、下床时间及住院时间均短于传统手术组（P<0.05）；3D打印组臼杯外展角偏差、前倾角偏差、髋关节旋转中心的垂直距离及水平距离偏差均小于传统手术组（P<0.05）；3D打印组术后3个月髋关节功能Harris评分高于传统手术组（P<0.05）；3D打印组术后3个月下肢力线低于传统手术组（P<0.05）；两组并发症发生率比较差异无统计学意义（P>0.05）。结论：3D打印技术辅助髋关节置换术的效果与传统手术相当，但其能够减少术中出血量，缩短手术时间、下床时间及住院时间，提升术后髋关节的稳定性，改善下肢力线。
Abstract:
Abstract: Objective To explore the application of 3D printing technology in hip replacement. Methods The clinical data of 130 patients who underwent hip replacement were retrospectively analyzed. According to different surgical approaches, the patients were divided into traditional surgery group (n=70) and 3D printing group (n=60). The evaluation indexes of surgery, imaging indexes, scores of hip function before and after surgery, force line of lower limbs and incidence of complications were compared between two groups. Results The intraoperative blood loss in 3D printing group was less than that in traditional surgery group, and moreover, the operation time, leaving bed time and hospitalization time were shorter than those in traditional surgery group (P<0.05). The deviations of acetabular cup abduction angle and anteversion angle as well as the vertical and horizontal distance deviations of hip rotation center in 3D printing group were smaller than those in traditional surgery group (P<0.05). At 3 months after surgery, compared with traditional surgery group, 3D printing group had a higher Harris score of hip function (P<0.05) and a lower force line of lower limbs (P<0.05) and no significant difference was found in the incidence of complications between two groups (P>0.05). Conclusion The effects of 3D printing technology and traditional surgery are comparable on assisting hip replacement. However, the former can reduce intraoperative blood loss, shorten operation time, leaving bed time and hospitalization time, improve stability of postoperative hip joint, and improve force line of lower limbs.
