Novel 3-point positioning technique combined with the TightRope system for treating acute Rockwood type III acromioclavicular joint dislocation

Figure 1 Schematic diagram of the three-point positioning technique.

Figure 2 Comparisons between preoperative and postoperative clinical evaluations. Comparisons between preoperative and postoperative scores. A: American Shoulder and Elbow Surgeons score; B: Shoulder and Elbow score; C: University of California, Los Angeles score; D: Constant-Murley score; E: Visual Analog Scale score; F: Shoulder Pain and Disability Index score. ^aP < 0.001, this shows that there was a significant difference before and after surgery using the Student’s t-test (P < 0.05); ^bP < 0.001, this shows that there was a significant difference before and after surgery using the Mann-Whitney U test (P < 0.05). ASES: The American Shoulder and Elbow Surgeons score; DASH: Shoulder and Elbow score; UCLA: University of California, Los Angeles score; CMS: Constant-Murley score; VAS: Visual Analog Scale score; SPADI: Shoulder Pain and Disability Index score.
