Abstract：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.
