“…The position of the tunnel was defined by the landmarks on the superior clavicle and coracoid, which were approximately 3.5 cm medial to the AC joint, equidistant between the anterior and posterior edges of the clavicle, and the midpoint of the inferior coracoid base 3 , 6 , 23 . In this group, the guide was the surgeon's finger.…”

“…Acromioclavicular (AC) joint dislocation is common among young and active sportsmen 1 , accounting for nearly half of all athletic shoulder injuries 2 . Surgical treatment is generally considered necessary in higher grades (IV–VI) of coracoclavicular (CC) ligament disruption, according to the Rockwood classification 1 , 3 , 4 . Many surgical techniques have been described to restore the anatomic relationship of the lateral clavicle to the acromion 5 , 6 , 7 , 8 .…”

“…In open surgery, transclavicular‐transcoracoid drilling in a traditional AC joint reconstruction is relatively less difficult because a large incision from the lateral end of the clavicle to the coracoid process enables direct visualization of all necessary structures around the AC joint 12 , 13 . However, this technique is associated with several problems such as a more obvious scar, slower soft tissue healing, and residual instability 3 , 14 . Minimally invasive procedures have been recently introduced for AR to avoid large incisions and extensive soft tissue dissection 8 , 15 , 16 .…”

Objectives: Ensuring the accuracy of transclavicular-transcoracoid drilling in the anatomical reconstruction of the coracoclavicular ligament complex with minimally invasive incisions remains a major problem for inexperienced surgeons. The purpose of this study was to design an assembly guide device for transclavicular-transcoracoid drilling with minimally invasive incisions, to manufacture the finished product, and to compare its feasibility and accuracy with the existing C-shape guide devices and free-hand techniques.Methods: An assembly-type guide device was designed and produced using computer-aided design and threedimensional printing. The specimen data of 54 human shoulders from 27 gross specimen (14 males and 13 females) treated by free-hand drilling, C-shape device drilling, and assembly-type guide device drilling from October 2018 to January 2021 were analyzed in a controlled laboratory study. Fifty-four human shoulder specimens were randomly assigned into free-hand (n = 18), C-shape (n = 18), and assembly (n = 18) groups by drawing lots for transclavicular-transcoracoid drilling by three inexperienced surgeons. After the drilling procedure was completed and the devices were removed, the operation outcomes were assessed and evaluated. Distances from the tunnel edge to the coracoid's medial (d m ) and lateral (d l ) edges, operation time, and tunnel location zones on the coracoid's inferior surface of all specimens in the three groups were measured to evaluate the surgical accuracy and efficiency.

“…Therefore, for young patients with high activity levels, surgery is recommended [ 3 ]. The most commonly used surgical procedure is an internal fixation with the double Endobutton technique [ 8 – 11 ]. However, the procedure can be complicated by collar plates trapped in the bone channel, fractures of the rostral process or clavicle, and loosening of the knot after the operation [ 12 ].…”

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.
