The aim of the study was to evaluate the efficacy custom 3D-printed osteosynthesis plates in the treatment of intercondylar humeral fractures.Thirteen patients with distal intercondylar humeral fractures were randomized to undergo surgery using either conventional plates (n = 7) or 3D-printed plates (n = 6) at our institution from March to October 2014. Both groups were compared in terms of operative time and elbow function at 6 month follow-up.All patients were followed-up for a mean of 10.6 months (range: 6-13 months). The 3D-printing group had a significantly shorter mean operative time (70.6 ± 12.1 min) than the conventional plates group (92.3 ± 17.4 min). At the last follow-up period, there was no significant difference between groups in the rate of patients with good or excellent elbow function, although the 3D-printing group saw a slightly higher rate of good or excellent evaluations (83.1%) compared to the conventional group (71.4%).Custom 3D printed osteosynthesis plates are safe and effective for the treatment of intercondylar humeral fractures and significantly reduce operative time.
本研究的目的是评估定制3D打印接骨板治疗肱骨髁间骨折的疗效。2014年3月至10月，13例肱骨远端髁间骨折患者在我院被随机分为两组，分别使用传统接骨板（n = 7）或3D打印接骨板（n = 6）进行手术。在6个月随访时，比较两组的手术时间和肘关节功能。所有患者平均随访10.6个月（范围：6 - 13个月）。3D打印组的平均手术时间（70.6 ± 12.1分钟）明显短于传统接骨板组（92.3 ± 17.4分钟）。在最后随访期，两组肘关节功能良好或优秀的患者比例无显著差异，尽管3D打印组的良好或优秀评估率（83.1%）略高于传统组（71.4%）。定制3D打印接骨板治疗肱骨髁间骨折安全有效，且能显著缩短手术时间。
