“…The continuous loop device can eliminate the possibility of knot breakage or slippage, and MRI suggested a robust healing response, which can be recommended both for chronic and acute dislocations [9]. Although the use of double endobutton plate technique for the treatment of Rockwood III-VI dislocations has been widely recognized, the improvement of the double endobutton technique has never stopped [8,9,10]. According to reset requirement during operation, our novel double endobutton can adjust loop length for satisfying different individual operative methods.…”

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.

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.

“…Acromioclavicular (AC) joint dislocation, a shared injury that accounts for approximately 9%-12% of shoulder girdle injuries (27), has received much attention in recent years. This injury is common in certain populations, such as teenagers and athletes, and its incidence is raising with the increase of traffic accidents and sports injuries (25). Depending on the rupture of ligaments and varying degrees of injury to the deltoid and trapezius muscles and fascia, Rockwood proposed a classification of AC joint dislocation to include type I to VI in 1984 (2).…”

“…Particularly, using grafts like tendon graft (4), or synthetic materials, such as anchors (23) and endobutton with suture (20, 25), to drill transosseous tunnels in the coracoid process and the clavicle for restoring the primitive anatomy of CC ligament has become the current tendency over the years (19). However, despite multiple clinical studies have indicated effective clinical and radiographic outcomes of the transclavicular-transcoracoid drilling technique (14,20), there is no gold standard for precisely how to create transosseous tunnels (14,19), which means a surgeon might reconstruct CC ligament from experience or in a routine manner of his own, so as to it is quite a few differences between the reconstructed ligament and the native CC ligament.…”

Background: Although the optimal surgical technique for treatment of acromioclavicular (AC) joint dislocation still remains controversial, reconstruction of the coracoclavicular (CC) ligament has become the current tendency, particularly the transclavicular-transcoracoid drilling technique. The study investigated the anatomical characteristic of CC ligament by obtained anatomical parameters based on magnetic resonance imaging (MRI), for guiding surgeons to create transosseous tunnels precisely in reconstructing CC ligament. Material/Methods : Four hundred and eighty MRI scans of left shoulders from patients (ages from 11 years to 80 years, mean age of 51 years) were analyzed for the study. Some anatomical parameters were defined and measured in images of the coronal and sagittal plane, including four angles and seven distances. All measurement results were analyzed by SPSS 20.0. Results : In the coronal plane, the distance form the midpoint of AC joint to the insertion at the clavicle of male patients was greater than the average value of female patients. In the sagittal plane, in addition to the diameter of insertion at the coracoid process, other average distance values of male patients were greater than the average values of female patients, which were significantly different (P<0.05). Conclusion : These anatomical parameters obtained from MRI could completely describe the anatomical characteristic of CC ligament, which are beneficial for the reconstruction of CC ligament to create transosseous tunnels accurately, contributing to reduce the incidence of postoperative complications and promote the operative treatment of AC joint dislocation.
