摘要
[目的]探讨3D打印辅助桥接系统个性化固定股骨粗隆间骨折的临床疗效.[方法]回顾性分析2017年1月-2021年9月采用3D打印辅助桥接系统固定股骨粗隆间骨折46例患者的资料,评价临床和影像学效果.[结果]所有患者均顺利完成手术,手术时间平均(78.3±16.2)min,术中出血量平均(210.2±113.3)ml,住院时间平均(13.1±5.0)d.随访12个月以上,与术后3个月相比,末次随访时疼痛VAS评分[(7.5±1.1),(2.1±0.9),(1.4±0.5),P＜0.001]显著减少,Harris评分[(77.3±3.5),(87.5±3.2),P＜0.001]和髋伸-屈ROM[(89.9±6.4)°,(124.3±7.9)°,P＜0.001]显著增加.影像学方面,与术前相比,术后骨折对位显著改善[优/良/可/差,(0/2/3/41),(15/24/6/1),(14/25/5/2),P＜0.001],颈干角[(93.7±3.9)°,(128.3±5.4)°,(126.2±5.2)°,P＜0.001]显著增加,所有病例均骨性愈合.[结论]3D打印结合桥接系统固定股骨粗隆间骨折近期效果满意,有利于个性化治疗.
Abstract
[Objective]To investigate the clinical efficacy of 3D printing assisted planning Ortho-Bridging system for personalized fixa-tion of femoral intertrochanteric fractures.[Methods]A retrospective research was done on 46 patients who had intertrochanteric fracture fixed with bridging system planned individually by 3D printing from January 2017 to September 2021.The clinical and imaging documents were evaluated.[Results]All patients were successfully operated,with the average operation time of(78.3±16.2)min,intraoperative blood loss of(210.2±1 13.3)ml,and hospital stay of(13.1±5.0)d,and followed up for more than 12 months.Compared with those 3 months postop-eratively,the pain VAS score significantly declined[(2.1±0.9),(1.4±0.5),P＜0.001],whereas Harris score[(77.3±3.5),(87.5±3.2),P＜0.001]and hip flexion-extesion range of motion(ROM)[(89.9±6.4)°,(124.3±7.9)°,P＜0.00 1]increased significantly at the latest fullow-up.Imag-ing,compared with those preoperatively,the fracture alignment significantly improved[excellent/good/can/poor,(0/2/3/41),(15/24/6/1),(14/25/5/2),P＜0.001],shaft-neck angle increased significantly 3 months postoperatively and the latest follow-up[(93.7±3.9)°,(128.3±5.4)°,(126.2±5.2)°,P＜0.001].All the patients got fracture healing at the latest follow-up.[Conclusion]This 3D printing assisted planning Ortho-Bridging system for fixation of femoral intertrochanteric fractures has satisfactory short-term consequence,which is conducive to personal-ized treatment.
