目的 探讨可吸收带线锚钉治疗O’Driscoll Ⅰ、Ⅱ型冠状突骨折的初步疗效。方法 回顾性分析 2017-01至2021-01陆军第八十二集团军医院骨科收治的O’Driscoll Ⅰ、Ⅱ型冠状突骨折的46例患者临床资料,根据患者不同手术方式,分为可吸收带线锚钉固定方式治疗组(锚钉组)和克氏针组(克氏针组),每组23例。比较两组患者手术时间、首次自主活动时间、术后并发症及肘关节活动度,并通过肘关节Mayo评分(MEPS)评价临床效果。结果 46例均顺利完成手术。锚钉组手术时间[(119.00±5.82)min]与克氏针组[(110.47±11.38)min]比较,差异无统计学意义。两组均完成随访,锚钉组首次自主活动时间(13.78±1.53)d明显早于克氏针组的(19.78±0.95)d, 差异有统计学意义(P<0.05);末次随访时,锚钉组肘关节屈曲活动度为(121.91±8.99)°,明显优于克氏针组的(101.95±4.38)°;锚钉组前臂旋转度为(130.34±5.40)°,也明显优于克氏针组的(103.21±6.06)°,差异均有统计学意义(P＜0.05);且锚钉组 MEPS评分优良率为91.3％,明显高于克氏针组的优良率(60.9％),差异也具有统计学意义(P＜0.05)。结论 采用可吸收带线锚钉治疗O’Driscoll Ⅰ、Ⅱ型冠状突骨折临床效果显著、固定牢靠、操作简单,利于早期功能锻炼。

Objective To investigate the preliminary effect of absorbable suture anchor in the treatment of O ’Driscoll type Ⅰ and Ⅱ coronary process fractures. Methods The clinical data of 46 patients with O ’Driscoll type Ⅰ and Ⅱ coronary fractures admitted to the Department of Orthopedics of the 82nd Group Hospital of PLA Army from January 2017 to January 2021 were retrospectively analyzed, and the patients were divided into absorbable suture anchor fixation group(anchor fixation group) and Kirschner pin fixation group(Kirschner pin fixation group) with 23 cases in each group according to the surgical methods. The operation time, first voluntary activity time , postoperative complications and elbow joint motion were compared between the two groups, and the clinical effect was evaluated by elbow Mayo score(MEPS). Results All the 46 cases successfully completed the operation. There was no significant difference in operation time between the anchor group [(119.00±5.82) min] and the Kirschner group [(110.47±11.38) min]. Both groups were followed up satisfactorily. The first voluntary activity time of the anchor group (13.78±1.53)d was significantly earlier than that of the Kirschner group (19.78±0.95)d, with statistical significance (P<0.05). At the last follow-up, the elbow flexural motion in the anchor group was (121.91±8.99), which was significantly better than that in the Kirschner group (101.95±4.38). The forearm rotation of the anchor pin group was (130.34±5.40), which was also significantly better than that of the Kirschner pin group (103.21±6.06)], with statistical significance (P<0.05). In addition, the excellent and good rate of MEPS score in anchor pin group was 91.3%, which was significantly higher than that in Kirschner pin group (60.9%), and the difference was statistically significant (P<0.05). Conclusions The treatment of O ’Driscoll type Ⅰ and Ⅱ coronary fractures with absorbable suture anchor is characterized by clinical effect, stable fixation and simple operation, which is conducive to early functional exercise.
