Abstract: Objective：To compare the early clinical effects of dissect Distal clavicle fracture(DCF) through Clavicular hook plate and Distal clavicle plate.Methods：To choose between August 2015 and January 2019 xiehe hospital affiliated to tongji medical college huazhong university of science and technology of clavicle admitted in orthopaedic clinical data of 114 patients with distal closed fracture were analyzed retrospectively,according to the surgery fixed in a different way,it can be divided into the anatomy of the collarbone steel group(52 cases,control group) with clavicular hook plate group(62 cases,the experimental group);with the control group of 32 cases.VAS scores were analyzed and compared between the two groups in terms of intraoperative operation time,bleeding volume,length of hospital stay,perioperative period and 1year postoperative followup.Results：The patients in both groups were followed up,and the followup time of the control group was 12~18 months [(14.5±2.4) months].Experimental followup time was 14~20 months [(16.5±3.8) months;generally have no obvious difference between two groups(P>0.05);perioperative VAS scores also had no statistical significance(P>0.05);the control group(9) [1] on the incidence of complications is slightly lower than the experimental group [4](6) incidence(P<0.05);the shoulder joint activity score group(85.7±12.6) is better than that of control group(80.1±10.2) score(P<0.05).Conclusion：Anatomical collarbone steel plate with clavicular hook plate distal clavicle fractures can get good healing rate,Although there was no significant difference between the two perioperative indexes,the clavicular hook plate had a certain advantage in recovering the range of motion of the shoulder compared with the anatomical clavicular plate.
