Abstract:【Objective】 To compare the effects of minimally invasive single-incision endobutton plate with clavicle hook plate in the treatment of Rockwood Ⅲacromioclavicular joint dislocation. 【Methods】 A total of 33 patients with Rockwood Ⅲ acromioclavicular joint dislocation who were treated in our hospital from January 2016 to January 2018 were selected and divided into the endobutton plate group (the observation group,16 cases)and the clavicle hook plate group(the control group,17 cases) according to the random number table.The perioperative indicators, operating time, hospital stays, intraoperative blood loss, length of the incision, shoulder pain(visual analogue scale,VAS) score,shoulder function Constant-Murley score and postoperative complications were compared between the two groups. 【Results】 The length of the incision and hospital stays in the observation group were shorter than those in the control group (P<0.05). The intraoperative blood loss in the observation group was less than that in the control group (P<0.05). After 1 week,1 month,3 months, 6 months and the last time of follow- up,the Constant-Murley score of the observation group was higher than that of the control group and the VAS score of the observation group was lower than that of the control group (P<0.05). The complication rate of the observation group was 12.5%(2/16), which was significantly lower than that of control group 52.9%(9/17), and the difference was statistically significant (P<0.05). 【Conclusion】 For patients with Rockwood Ⅲ acromioclavicular joint dislocation, Single-incision double button plate fixation obtains less complications, fewer operative trauma and good shoulder joint function, which is an ideal treatment.
