Abstract: Objective  To investigate the clinical effect of Tossy Ⅲ acromioclavicular dislocation treated by suture anchor and suture bridge technique. 
Methods  Sixty-four cases of fresh TossyⅢ acromioclavicular dislocation were randomly divided into observation group and control group, 32 cases in each group, the observation group treated by suture anchor and suture bridge technique;the control group treated by using clavicular hook plates.The functional recovery time of the two groups was compared, the joint function was evaluated, and the complications were observed. 
Results  Sixty-four cases were followed up  for 6-18 months, with an average of 12 months. The excellent and good rate in the observation group was higher than that in the control group according to the Lazzcano evaluation standard(P＜0.05). Daily activity time of observation group was shorter than that of control group, the difference was statistically significant(P＜0.01). The incidence of postoperative complications in the observation group was lower than that in the control group(P＜0.05). 
Conclusion  The treatment of TossyⅢ acromioclavicular joint dislocation by suture anchor and suture bridge is a simple and effective method. Combined with early postoperative functional training,satisfactory clinical results can be obtained.
