We compared patient satisfaction and clinical effectiveness of 3D-printed splints made of photopolymer resin to conventional fibre glass casts in treating distal radial fractures. A total of 39 patients with minimally displaced distal radius fractures were included and randomized. Of them, 20 were immobilized in a fibre glass cast and 19 in a 3D-printed forearm splint. The 3D-printed splints were custom-designed based on forearm surface scanning with a handheld device and printed in-house using digital light processing printing technology. Patient satisfaction and clinical effectiveness were assessed with questionnaires 1 and 6 weeks after the initiation of immobilization. Fracture healing, pain, range of motion, grip strength and the DASH and PRWE scores were assessed up to 1-year follow-up. 3D-printed splints proved to be equally well tolerated by the patients and equally clinically effective as conventional fibre glass casts although there was a higher rate of minor complications. 3D-printed splints present a safe alternative, especially in young, active patients, for non-operative treatment of distal radial fractures.

我们比较了 3D 打印光聚合树脂夹板和传统玻璃纤维夹板治疗桡骨远端骨折的患者满意度和临床疗效。共纳入 39 例轻度移位的桡骨远端骨折患者，并进行随机分组。其中 20 例采用玻璃纤维夹板固定，19 例采用 3D 打印前臂夹板固定。3D 打印夹板是根据手持设备对手前臂表面进行扫描定制的，并使用数字光处理打印技术在内部打印。在固定开始后 1 周和 6 周，使用问卷评估患者满意度和临床疗效。直至 1 年随访时，评估骨折愈合情况、疼痛、活动范围、握力以及 DASH 和 PRWE 评分。尽管 3D 打印夹板的轻微并发症发生率较高，但患者耐受性和临床疗效与传统玻璃纤维夹板相当。3D 打印夹板是一种安全的替代方法，尤其适用于年轻、活跃的非手术治疗桡骨远端骨折患者。
