The aim of this study was to explore the efficacy of a novel intramedullary fixation technique using the ortho-bridge system (OBS) for midshaft clavicle fractures.
A total of 63 patients were included in this study: 35 underwent plate internal fixation (LP group) and 28 underwent OBS intramedullary fixation (OBS group). Surgical time, intraoperative blood loss, incision length, fracture healing time, removal of the internal fixation agent, visual analog scale (VAS) score for shoulder pain, Constant-Murley shoulder score and complication occurrence were compared between the two groups.
Preoperative general data, such as sex, age and fracture type, were not significantly different between the two groups (P > 0.05). However, the OBS group exhibited better outcomes than the LP group exhibited in terms of surgical time, intraoperative blood loss and total incision length (P < 0.05). Additionally, the OBS group exhibited a significantly shorter fracture healing time and internal-fixation removal time than the LP group exhibited (P < 0.05). The VAS scores on postoperative day 1, week 1, month 1 and month 3 were lower in the OBS group than in the LP group (P < 0.05). Furthermore, the Constant-Murley shoulder scores at 1, 3, and 6 months postoperatively were higher in the OBS group than in the LP group (P < 0.05), with no significant difference at 1 year after surgery (P > 0.05). None of the patients in the OBS group experienced scarring of the surgical incision, and 6 patients in the LP group experienced scarring of the surgical incision. Finally, the complication incidence in the OBS group was lower than that in the LP group.
For midshaft clavicle fractures, OBS intramedullary fixation is better than locking-plate internal fixation because it led to less trauma, a faster recovery, better efficacy, and better esthetic outcomes and comfort. Therefore, this technique may have potential as a novel treatment for midshaft clavicle fractures.

本研究旨在探讨使用 Ortho-Bridge 系统（OBS）进行锁骨中段骨折的新型髓内固定技术的疗效。
本研究共纳入 63 例患者：35 例行钢板内固定（LP 组），28 例行 OBS 髓内固定（OBS 组）。比较两组患者的手术时间、术中出血量、切口长度、骨折愈合时间、内固定取出时间、肩关节疼痛视觉模拟评分（VAS）、Constant-Murley 肩关节评分和并发症发生情况。
两组患者术前一般资料（性别、年龄和骨折类型）比较差异无统计学意义（P>0.05）。但 OBS 组在手术时间、术中出血量和总切口长度方面均优于 LP 组（P<0.05）。此外，OBS 组骨折愈合时间和内固定取出时间均明显短于 LP 组（P<0.05）。OBS 组术后第 1、1 周、1 个月和 3 个月的 VAS 评分均低于 LP 组（P<0.05）。此外，OBS 组术后 1、3 和 6 个月的 Constant-Murley 肩关节评分均高于 LP 组（P<0.05），术后 1 年两组比较差异无统计学意义（P>0.05）。OBS 组患者切口均无瘢痕形成，LP 组 6 例切口有瘢痕形成。最后，OBS 组并发症发生率低于 LP 组。
对于锁骨中段骨折，OBS 髓内固定优于锁定钢板内固定，因为它导致的创伤更小、恢复更快、疗效更好、美容效果和舒适度更好。因此，该技术可能为锁骨中段骨折提供一种新的治疗方法。
