3D printing technology assisted scapula modified Judet approach for the treatment of scapular frac-tures

目的探讨3D打印技术辅助肩胛骨改良Judet入路手术治疗肩胛骨骨折的疗效。方法前瞻性收集2016年10月到2020年6月广州医科大学附属顺德医院骨外科收治的63例肩胛骨骨折患者,年龄17~59岁,其中男性40例,女性23例,随机分成2组,对照组(30例行)改良Judet入路手术,研究组(33例)行3D打印技术辅助下的改良Judet入路手术,比较两组围术期一般指标、术后肩关节功能恢复及并发症发生情况。结果研究组手术时间[(96±16)min]、术中出血量[(263±19)mL]及术中透视次数[(4.2±0.9)次]均明显小于对照组[(145±24)min、(342±35)mL、(8.5±2.1)次](P<0.001);两组患者复查X线片提示骨折均愈合,两组骨折愈合时间比较差异无统计学意义[(7.9±1.8)vs(8.6±2.0)个月](P>0.05);研究组肩关节功能优良率为81.82%,明显高于对照组(66.67%),组间比较差异有统计学意义(P<0.05);两组术后并发症发生情况无明显差异(P>0.05)。结论3D打印技术辅助改良Judet入路手术治疗肩胛骨骨折可缩短手术时间,减少术中出血量,降低医患射线暴露风险,提升术后肩关节功能效果。

Objective To explore the effect of 3D printing technology assisted scapular modified Ju-det approach for the treatment of scapular fracture.Methods We prospectively collected 63 patients with scapula fractures from October 2016 to June 2020 in the Department of Orthopedics,Shunde Hospital Affiliat-ed to Guangzhou Medical University,aged 17-59 years,including 40 males and 23 females,They were ran-domly divided into 2 groups,the control group(30 cases)with modified Judet approach and minimally inva-sive surgery.Group(33 cases)underwent a modified Judet approach minimally invasive surgery assisted by 3D printing technology,and compared the two groups'perioperative general indicators,postoperative shoul-der function recovery and complications.Results The operation time[(96±16)min],intraoperative blood loss[(263±19)mL]and intraoperative fluoroscopy times[(4.2±0.9)times]in the study group were significant-ly shorter than those in the control group[(145±24)min],(342±35)mL,(8.5±2.1)times](P<0.001);The X ray films of the two groups showed that the fractures healed,and there was no significant difference in the fracture healing time between the two groups[(7.9±1.8)vs(8.6±2.0)months](P>0.05);The excellent and good rate of shoulder joint function in the study group was 81.82%,which was significantly higher than that in the control group(66.67%),and the difference between the two groups was statistically significant(P<0.05).Conclusion 3D printing technology assisted by modified Judet approach minimally invasive surgery for scapular fractures can shorten the operation time,reduce intraoperative blood loss,reduce the risk of doc-tor-patient radiation exposure,and improve postoperative shoulder joint function.
