Abstract Background Numerous surgical methods have been used for acromioclavicular joint reconstruction.In this study, we analyzed the clinical and radiographic outcomes of truly anatomic coracoclavicular ligaments reconstruction (TACCR) and truly anatomic acromioclavicular ligaments reconstruction (TAACR) using suture anchor and Endobutton fixation for treatment of acromioclavicular joint dislocation. Methods 48 patients (mean age 49 years) with severe acromioclavicular joint dislocation. The patients were classified as Rockwood type III (n=28), IV (n=3) and V (n=17). All patients were operatively treated using anchor moored positioning technique by suture anchor and Endobutton fixation. Clinical and radiographic evaluation include the visual analog scale (VAS), Constant scores (CS) and American Shoulder and Elbow Surgeons (ASES) scores and radiographic outcomes. Results The mean follow-up was 34 months. The VAS decreased from 5 preoperatively to 0 at 24 months (P < .001). The CS and ASES scores improved from 43, 44 preoperatively to 96, 97 at 24 months separately (P < .001). Meanwhile, 47 patients (97.9%) demonstrated stable anatomical fixation on final postoperative radiographs. Loss of reduction occurred in 1 patient (2.1%), but was not correlated with functional outcome. Conclusions Anchor moored positioning technique with Bi-directional fixations by suture anchor and Endobutton fixation represents a new and reliable treatment of AC joint dislocation.

Abstract Purpose This study aimed to assess the biomechanical stability of a novel internal fixation system of EndoButton plate combined with suture anchor in treating acromioclavicular joint dislocation in the cadaveric specimens. In addition, it provides a new method for the clinical treatment of acromioclavicular joint dislocation. Methods Twelve complete shoulder joint specimens were randomly divided into groups A, B, C, and D (n = 3). Firstly, a quasi-static non-destructive circulation experiment was carried out of coracoclavicular ligament until its function failed. Four different internal fixation materials were used to reduce and fix the acromioclavicular joint. Group A was treated with 3.5 mm clavicular hook locking compression plates, Group B with 5 mm suture anchor Group C with 10 mm Endo-button plate, and Group D with a novel combination of 5 mm suture anchor and 10 mm Endo-button plate. Fluoroscopy was performed to undertake the X-ray of the restored acromioclavicular joint, to evaluate the internal fixation position and acromioclavicular joint reduction. Finally, the shoulder joint was fixed firmly on an electronic universal testing machine (100KN) with a self-made stationary fixture, to conduct a destructive static tensile mechanical test of each specimen vertically at a 100 mm/min load speed. The stress-deformation curve was recorded using a computer connected with the universal mechanical testing machine, and the failure strength and reasons for internal fixation were also recorded. Results The average load-to-failure of the coracoclavicular ligament in groups A, B, C, and D was 373.4 ±0.57 N, 373.6 ±0.62 N, 374.4 ±0.68 N, and 373.9 ±0.15 N, respectively (P>0.05). After internal fixation failure, Group A showed two specimens with clavicular fracture, and one with acromial fracture, with an average load-to-failure of 409.8 ±2.92 N. Group B and D showed three specimens with prolapse of anchor, with average load-to-failure of 293.5 ±4.10 N and 374.2 ±0.40 N, respectively. Group C showed three specimens with basilar coracoid fracture, with average load-to-failure of 373.2 ±2.35 N. Statistical differences existed in the biomechanical load of internal fixation failure among the four groups. Group D was statistically different from Group A and Group B, but not Group C. Conclusion The newly designed EndoButton plate combined with suture anchor for coracoclavicular ligament reconstruction was found to boast simple operation and has high feasibility. Thus it was found effective in the reduction of acromioclavicular joint and treatment of acromioclavicular joint dislocation and fitted the biomechanical characteristics of the acromioclavicular joint.

Abstract Purpose Double-endobutton technique, as a widely accepted strategy for the treatment of acromioclavicular joint dislocation, is undergoing constant improvement. This study aims to assess the clinical effect of a modified single-endobutton combined with the nice knot in the fixation of Rockwood type III or V acromioclavicular joint dislocation. Methods From January 2016 to June 2019, 16 adult patients (13 males and 3 females) with Rockwood type III or V acromioclavicular joint dislocation were treated with a modified single-endobutton technique combined with the nice knot in our department. The age ranged from 18 to 64 years old with an average of 32.8 years old. Operative time, intraoperative blood loss, post-operative clinical outcomes and radiographic results were recorded and analyzed. Preoperative and last follow-up scores in the Constant-Murley Scale, Neer score, Rating Scale of the American Shoulder and Elbow Surgeons and VAS scale and complications such as infection, re-dislocation, implant loosening, medical origin fracture and hardware pain were recorded and evaluated. Results Sixteen patients were followed up for 6 to 18 months with an average of 10.3 months. The operative time was 50–90 min with an average of (62.5 ± 3.10) min. The intraoperative blood loss was 30–100 ml, with an average of (55.0 ± 4.28) ml. The complications, such as wound infection, internal fixation failure and fractures, were not found in these cases. According to Karlsson criteria, there were excellent in 14 cases, good in 2 cases at the final follow-up. The mean VAS score of the patients was 5.88 ± 0.26 preoperatively, compared with 0.19 ± 0.14 at the final follow-up evaluation. The difference was statistically significant (P < 0.05). The mean Constant score was 45.5 ± 2.0 preoperatively, compared to 94.0 ± 0.73 at the final follow-up evaluation. The difference was statistically significant (P < 0.05). Patients had statistically significant preoperative and postoperative AC (acromioclavicular distance) and CC (coracoclavicular distance) distances (P < 0.05); 6 months postoperatively the AC(P = 0.412) and CC(P = 0.324) distances were not statistically significant compared to the healthy side. Conclusion Nice knot provides a reliable fixation for the single-endobutton technique in the treatment of acromioclavicular dislocations. The modified single-endobutton technique combined with the nice knot can achieve good clinical outcomes in the treatment of Rockwood type III or V acromioclavicular joint dislocation.
