Abstract:
ObjectiveThe study aims to determine whether the horizontal posterior displacement of the distal clavicle in patients with acromioclavicular joint dislocation can be corrected via the application of modified intraoperative axillary fluoroscopy. MethodsFrom February 2019 to April 2021， 50 patients with Rockwood type Ⅲ acromioclavicular joint dislocation eligible for inclusion were randomly divided into two groups： the normal （32 cases） and the experimental （18 cases）. The conventional anteroposterior position radiographs were obtained to detect the surgery effect on the patients in the normal group. In experimental group， modified intraoperative axillary radiographs were obtained， with the concept of polar coordinates introduced to reduce the horizontal posterior translation of the clavicle. Then we compared the perioperative parameters， such as average operative time， intraoperative blood loss between the two groups. The Constant score was used for assessing the postoperative function of the shoulder joint in the follow-up visits. ResultsNo statistically significant difference was found in gender， age， duration of injury， underlying diseases， intraoperative blood loss and operative time between the two groups. The postoperative shoulder function score of the experimental group was higher than that of the normal group. ConclusionsThe application of modified intraoperative axillary fluoroscopy is recommendable for accurately reducing posterior translation of the distal clavicle， and meanwhile helpful for the precise placement of the clavicular plate.
