3D 打印联合Y 型板与重建板治疗 肩胛骨骨折的疗效比较

Scapular fractures treated with 3D printing and Y-type plates or reconstruction plates

摘要:

目的 观察3D 打印联合Y 型锁定板与非3D 打印重建接骨板治疗肩胛骨体部合并颈部和/ 或 肩胛冈基底部不稳定骨折的临床疗效。方法 回顾性分析2013 年7 月—2016 年7 月汉中市中心医院肩胛骨 体部合并颈部和/ 或肩胛冈基底部不稳定骨折30 例，分为3D 打印Y 型锁定板固定组12 例（A 组）和非3D 打印重建接骨板固定组18 例（B 组）。对两组手术时间、术中失血量、Constant 肩关节功能及并发症情况进 行分析。结果 两组手术时间、术中失血量及肩关节功能比较，差异有统计学意义（P <0.05）；术后无感染、 骨折不愈合及医源性血管神经损伤等并发症发生。结论 在3D 打印模型精准指导下，Y 型锁定板处理不稳 定性肩胛骨骨折能缩短手术时间，减少术中失血量，效果良好，优于重建锁定板。

Abstract:

Objective To observe the clinical efficacy of 3D printing and Y-type locking plates or reconstruction locking plate in unstable fractures of scapular body with the neck and/or the basilar part of scapula spine. Methods This is a retrospective study of 30 patients with unstable fractures of scapular body and neck and/or the basilar part of scapula spine treated in the Hanzhong Central Hospital in Shaanxi Province from July 2013 to July 2016. Among them, 12 patients received 3D printing and Y-type locking plates (Group A) and 18 patients received reconstruction locking plates (Group B). The operative time, intraoperative blood loss, Constant shoulder function and complications were analyzed. Results The two groups are compared in the operative time, intraoperative blood loss and shoulder joint function, and the differences are statistically significant (P<0.05). No complications such as infection, fracture nonunion, iatrogenic vascular and nerve injury occurred after operation. Conclusions Under the precise guidance of the 3D printing model, the treatment of unstable scapular fracture with Y-type locking plate has shorter operation time, less intraoperative blood loss and better clinical effect than that with reconstruction locking plate.
