Abstract: Objective 　To compare the difference of clinical effect between Kirschner wire loop plate and anatomical locking plate combined with ligaments suspended for the treatment of Neer IIb distal clavicle fracture.　Methods　According to different fixation methods, 46 patients with Neer IIb distal clavicle fracture who received treatment were divided into an observation group (22 patients with Kirschner wire loop plate) and a control group (24 patients with anatomical locking plate combined with ligaments suspended). Operation time, fluoroscopy frequency, intraoperative blood loss, incision length, fracture healing time, hospital stay, VAS pain score and Constant function score of shoulder joint and other indicators were evaluated.　Results　Intraoperative blood loss, incision length and fracture healing time in the observation group were significantly lower than those in the control group (P<0.05). While the operation time and fluoroscopy times in the observation group were significantly higher than those in the control group (P<0.05). There was no significant difference in the hospital stay between the two groups (P>0.05). The gap distance of beak lock in the observation group was lower than that in the control group (P<0.05). There were no statistical difference in the immediate VAS score and Constant function score between the two groups (P>0.05). At 3 months follow-up, the VAS score and the Constant function score of shoulder joint in the observation group were better than control group (P<0.05).　Conclusions　Kirschner wire loop plate for the treatment of Neer IIb distal clavicle fracture is safe and effective, and can effectively improve the quality of life of patients, which is worthy of extensive clinical promotion.
