Objective To investigate the efficacy of looped plate combined with suture anchor in the treatment of acro-mioclavicular joint dislocation.Methods The 23 patients with acromioclavicular joint dislocation were treated with looped plate combined with suture anchor.The occurrence of complications,pain VAS,Constant score,and shoulder joint activity were recorded.Results All patients were followed up for 13~26 months.There were no signs of numb-ness or nerve damage after surgery,and no complications such as stress fractures occurred;two cases experienced slight pain and limited mobility when lifting the shoulder joint,while one case experienced slight detachment of the in-ternal fixation due to premature exercise,these cases were not performed with special treatment due to their minimal impact on shoulder joint function.Pain VAS,Constant score and shoulder joint range of motion:they were all better than preoperation at 6 weeks and 3 and 12 months after surgery(P<0.05);the postoperative outcomes got better over time,and the differences had statistical significance(P<0.05).At the last follow-up,the patients had no obvious pain in the shoulder joint and returned to normal life.The Constant score was used to evaluate shoulder joint function:ex-cellent in 16 cases,good in5,fair in2,with an excellent-good rate of 21/23.Conclusions The treatment of acromi-oclavicular joint dislocation with looped plate combined with suture anchor has the advantages of little postoperative activity impact,no need to remove internal fixation,and good recovery of shoulder joint activity.
