additional electronic search(including MEDLINE

EMBASE and CBM)

and hand-searched for corresponding Chinese Journals.Data were extracted and evaluated.Results:Two published trials including a total of 144 patients met the inclusion criteria for the review

while another

maybe

had slight bias.The mate analysis demonstrates that non-operative managements are better than operative managements according to return subjects to normal walking and take part in athletic sports

and that there have no different between the two methods according to rehabilitation of the physical function.Complications also have been reported in it.Conclusion:Conservative and surgical treatments being used to treat acromioclavicular dislocation
