Abstract:
Objective To explore the efficacy of internal fixation of TightRope buckle steel plate with robot assistance for acute acromioclavicular joint dislocation.Methods From October 2022 to December 2023,17 patients with acute acromioclavicular dislocation admitted to our hospital were treated with robot assisted TightRope buckle steel plate fixation.According to the Rockwood classification,there were 2 patients with type Ⅱ and 15 patients with type Ⅲ.Preoperative planning was carried out by the robot's"super brain".During the surgery,under the guidance of the robotic arm,a hole was drilled from the clavicle to the coracoid process,and one end of the loop steel plate was pushed into the coracoid process to tighten the tail line,achieving the goal of resetting the acromioclavicular joint.Results The operations were successfully completed in all the 17 patients,with an operation time of 15-42 min(mean,27.9 min)and intraoperative blood loss of 5-25 ml(mean,10.4 ml).Postoperative DR showed that the acromioclavicular joint had been reduced.All incisions healed in one stage without any vascular or nerve related complications.On the second day after surgery,CT evaluation showed that the accuracy of clavicle drilling position was excellent in 12 cases and good in 5 cases and accuracy of coracoid process drilling was excellent in 9 cases,good in 7 cases,and poor in 1 case.All the 17 patients were followed up for 6-12 months,with an average of 10.4 months.On the second day and six months after surgery,there were no significant differences in the distance between the surface cortex below the acromion and the surface cortex below the distal clavicle on the affected and healthy side[0.15(0.00,0.50)mm vs.-0.40(0.70,0.70)mm,Z=-1.553,P=0.120;0.15(0.00,0.50)mm vs.0.20(-0.25,0.85)mm,Z=-0.466,P=0.641].At six months after surgery,the distance between the surface cortex below the acromion and the surface cortex below the distal clavicle on the affected side was significantly higher than on the second day[0.20(-0.25,0.85)mm vs.-0.40(0.70,0.70)mm,Z=-3.426,P=0.001].On the second day after surgery,the Visual Analogue Scale(VAS)score was 3.0(3.0,4.0)points,significantly lower than the preoperative score of 4.0(3.5,5.5)points(Z=-2.716,P=0.007).On the sixth month,the VAS score was1.0(0.0,1.5)points,significantly lower than the preoperative score(Z=-3.649,P=0.000)and on the second day after surgery(Z=-3.672,P=0.000).At the last follow-up,the Constant Murley score for shoulder joint function ranged 91-100 points,with an average of 94.3 points,all of which were excellent.The American Shoulder and Elbow Surgeons(ASES)score ranged 87-100 points,with an average of 96.7 points,the excellent and good rate being 100%(15 cases were excellent and 2 cases were good).Conclusion The use of robot assisted TightRope buckle loop steel plate internal fixation technology for the treatment of acute Rockwood type Ⅱ and Ⅲ acromioclavicular dislocation has good therapeutic effects.
