“…There has been an exponential increase in the number of publications on surgical AC joint reconstruction and repair over the past few years[ 2 ]. Recent studies have concentrated on minimally invasive or arthroscopic anatomical reconstruction of the CC ligaments[ 2 , 7 , 13 , 58 , 76 ]. Although many improvements have been made, some questions still remain: How many drill holes are needed in the coracoid and clavicle?…”

A direct force on the superior aspect of the shoulder may cause acromioclavicular (AC) dislocation or separation. Severe dislocations can lead to chronic impairment, especially in the athlete and high-demand manual laborer. The dislocation is classified according to Rockwood. Types I and II are treated nonoperatively, while types IV, V and VI are generally treated operatively. Controversy exists regarding the optimal treatment of type III dislocations in the high-demand patient. Recent evidence suggests that these should be treated nonoperatively initially. Classic surgical techniques were associated with high complication rates, including recurrent dislocations and hardware breakage. In recent years, many new techniques have been introduced in order to improve the outcomes. Arthroscopic reconstruction or repair techniques have promising short-term results. This article aims to provide a current concepts review on the treatment of AC dislocations with emphasis on recent developments.

“…With this limited exposure of the coracoid and minimally invasive approach, a surgeon can place the suture anchors by using the bone tunnel to maintain AC joint well [22]. The 3-tunnel reconstruction technique faithfully restored these insertion points on the clavicle and dominated the movement of the graft on the coracoid process, which was closer to restoring the natural movement of the shoulder than the CC sling technique [11].…”

Background: Finding ideal bone tunnel location is key to reconstruction of the coracoclavicular (CC) ligament, which has become a fundamental surgical method for acromioclavicular (AC) joint dislocation. The study aims to explore virtual model vs. real model of accurate bone tunnel location in coracoclavicular (CC) ligament reconstruction based on 3-dimensional (3D) navigation module printing technology.Methods: Eighty human shoulders including clavicle and scapula were scanned by dual-source computed tomography (CT). CT scans of shoulder joints including clavicle and scapula were imported, the acromioclavicular joints were repositioned to form a whole model, and find the best bone tunnel through digital optimization design by Mimics 19.0 software. In Geomagic Studio software, forming the clavicle navigation module, which was generated for 3D printing. Then 10 parameters of a real bone tunnel and virtual bone tunnel can be measured and compared.Results: Eighty human shoulders including clavicle and scapula were designed and printed successfully. Then 10 parameters of the real and virtual bone tunnels were recorded and compared. No difference was significantly found between the real and virtual bone tunnels in 10 measurements (p>0.05).Conclusions: The accuracy of bone tunnel location for CC reconstruction in adult shoulders based on 3D printing navigation module technology is reliable.

“…The Endobutton plate was initially used to reconstruct the cruciate ligament of the knee joint, and then gradually became an implant for the surgical treatment of acromioclavicular joint dislocation. Many clinical investigators have used Endobutton plate for single-bundle coracoclavicular ligament reconstruction, and achieved some short-term therapeutic effects (22)(23)(24)(25). However, with the in-depth anatomical study of the stable structure of the acromioclavicular joint, some researchers believe that double-bundle anatomical reconstruction is the key factor for postoperative stability of the acromioclavicular joint and it is necessary to reconstruct the two branches of the coracoclavicular ligament: the trapezoid ligament and the conus ligament.…”

Acromioclavicular joint dislocation is a common sports injury disease, surgical treatment to restore the acromioclavicular joint stability, including stability and vertical stability level. However, vertical stability is often neglected. So we did a retrospective study enrolled 38 patients using Endobutton reconstruction and suture repair (Group A) with those using single Endobutton (Group B). The perioperative assessments contained coracoclavicular distance (CCD), Constant-Murley shoulder joint score, University of California at Los Angeles (UCLA) shoulder joint score and the difference between bilateral CCD 12 months postoperatively. The evaluation of group A was significantly better than group B. Constant-Murley scores and UCLA shoulder scores preoperatively were significantly higher than those after operation. The postoperative CCD of the two groups was lower than that before surgery. CCD between the affected shoulder and another postoperatively was no difference in group A, but was different in group B. The difference of postoperative CCD of the two groups was different. Afterward, we evaluated the stress and deformation around the acromioclavicular joint by finite element analysis and found that the stress dispersion and displacement reduction enhanced the stability of acromioclavicular joint. Thus, reconstruction of coracoclavicular ligament with Endobutton and sutures repair can increase the stability of acromioclavicular joint.
