To analyze the clinical efficacy of manual reduction combined with 3D printing small splint external fixation and synchronous manual reduction combined with traditional small splint external fixation in the treatment of humeral shaft.
Between January 2021 and December 2022, 40 patients with humeral shaft fractures were treated with 3D printing small splints and traditional small splints. They were divided into 3D group and traditional group according to different fixation methods. Among them, there were 15 males and 5 females in the 3D group, aged from 20 to 52 years old with an average of (36.3±15.6) years old. In the traditional group there were 17 males and 3 females, aged from16 to 51 years old with an average of (32.9±17.2) years old. The occurrence of complications, duration of fracture healing, rate of fracture healing, subjective evaluation scores for brace comfort at 1 week and 4 weeks, as well as the Constant-Murley shoulder function score and Mayo elbow function score at 8 weeks and 16 weeks were compared between the two groups.
All patients were followed up for 16 weeks. The 3D group did not experience any complications, while there were two cases of complications in the traditional group. However, this difference was not found to be statistically significant (=2.105, =0.146). The fracture healing time of the 3D group (90.1±4.5) days was significantly shorter compared to that of the traditional group (93.3±3.8) days (<0.05). The subjective evaluation scores for brace comfort in the 3D group (53.7±2.3) points and (62.8±1.1) points were significantly higher than those in the traditional group (45.6±2.4) points and (52.3±1.4) points at 1 and 4 weeks after reduction (<0.05). After 8 weeks of reduction, the Constant-Murley shoulder function score in the 3D group was(68.1±5.3) points, which demonstrated a statistically significant improvement compared to the traditional group(54.3±4.9) points (<0.05). However, at 16 weeks post-reduction, there were no significant differences observed between the two groups (>0.05). The Mayo elbow function score of the 3D group (84.1±7.5) points was significantly superior to that of the traditional group (79.5±6.8) points at 8 weeks post-reduction (<0.05). However, there was no statistically significant difference between the two groups at 16 weeks post-reduction (>0.05).
For humeral shaft fractures with conservative treatment indications, manual reduction combined with 3D printed small splints is a good choice for treatment. The patient's comfort level is higher, which can not only reduce the occurrence of complications, but also improve the fracture healing rate and joint function to a certain extent, and improve the patient's quality of life.
分析手法复位联合3D打印小夹板外固定与同步手法复位联合传统小夹板外固定治疗肱骨干骨折的临床疗效。
2021年1月至2022年12月，对40例肱骨干骨折患者采用3D打印小夹板和传统小夹板治疗。根据固定方法不同分为3D组和传统组。其中，3D组男15例，女5例，年龄20～52岁，平均（36.3±15.6）岁。传统组男17例，女3例，年龄16～51岁，平均（32.9±17.2）岁。比较两组并发症发生情况、骨折愈合时间、骨折愈合率、复位后1周和4周支具舒适度主观评价得分，以及复位后8周和16周的Constant-Murley肩关节功能评分和Mayo肘关节功能评分。
所有患者均随访16周。3D组未发生任何并发症，传统组有2例并发症。但差异无统计学意义（χ²=2.105，P=0.146）。3D组骨折愈合时间（90.1±4.5）天，明显短于传统组（93.3±3.8）天（P<0.05）。复位后1周和4周，3D组支具舒适度主观评价得分（53.7±2.3）分和（62.8±1.1）分，明显高于传统组（45.6±2.4）分和（52.3±1.4）分（P<0.05）。复位后8周，3D组Constant-Murley肩关节功能评分为（68.1±5.3）分，与传统组（54.3±4.9）分比较差异有统计学意义（P<0.05）。但复位后16周，两组间差异无统计学意义（P>0.05）。复位后8周，3D组Mayo肘关节功能评分（84.1±7.5）分，明显优于传统组（79.5±6.8）分（P<0.05）。但复位后16周，两组间差异无统计学意义（P>0.05）。
对于有保守治疗指征的肱骨干骨折，手法复位联合3D打印小夹板是一种较好的治疗选择。患者舒适度较高，不仅能减少并发症的发生，还能在一定程度上提高骨折愈合率和关节功能，改善患者生活质量。
