ABSTRACT
Objective To systematically evaluate the clinical effects of endobutton plate and clavicular hook plate in the treatment of ac-romioclavicular joint dislocation. Methods The clinical study on endobutton plate and clavicular hook plate in the treatment of acromiocla-vicular joint dislocation was subjected to computer search for CNKI,VIP,WangFang Data,PubMed,EMbase and The Cochrane Library input before July 2017. Two reviewers independently screened literature,extracted data and assessed the risk bias of included studies and then Rev-Man 5. 3 software was used to perform meta-analysis. A total of 10 studies were conducted with 725 patients. Results After operation of the patients who underwent endobutton plate,the Constant score was higher [MD=8. 55,95％CI (7. 82, 9. 29),P<0. 01] with shorter opera-tion time [MD=4. 94, 95％CI 4. 30 to 5. 59,P< 0. 01],less bleeding (MD= -1. 93,95％CI -2. 63 to -1. 22,P<0. 01],and shorter hospital stay [MD= -0. 39, 95％CI -0. 70 to -0. 09,P=0. 01],respectively. Conclusion The treatment of acromioclavicular joint dis-location with type III by endobutton plate has the advantages of shorter operation time,less intraoperative bleeding,quick recovery of shoulder function,and shorter hospital stay.
