A Technique for a More Accurate Acromioclavicular Joint Reduction in Arthroscopic Coracoclavicular Stabilization of Acromioclavicular Joint Dislocation.

ABSTRACT: Loss of reduction is the most common complication following acromioclavicular dislocations treatment, with literature showing greater postoperative coracoclavicular distances associated with worse clinical results. We present a surgical gesture that aims to help surgeons achieve and secure an anatomic acromioclavicular reduction during coracoclavicular fixation. This technique has the possibility to improve radiological and functional results of acromioclavicular dislocation treatment.

Arthroscopic Coracoclavicular and Acromioclavicular Stabilization of Acute Acromioclavicular Joint Dislocation By Suspensory Fixation System.

Project description:Arthroscopic stabilization of acute acromioclavicular joint dislocations using coracoclavicular suspension techniques has become more popular, but lack of horizontal stability is a major concern that furthermore affects the final outcome. We present an arthroscopic technique to stabilize acute acromioclavicular joint dislocations in both the vertical and horizontal planes, with better results than conventional coracoclavicular suspension techniques.

Arthroscopic Technique for Stabilization of Chronic Acromioclavicular Joint Instability With Coracoclavicular and Acromioclavicular Ligament Reconstruction Using a Gracilis Tendon Graft.

Project description:We present an arthroscopic technique for stabilization of chronic acromioclavicular (AC) joint instability using a transclavicular-transcoracoidal button technique, combined with a coracoclavicular and AC ligament reconstruction using the gracilis tendon. This arthroscopic technique achieves an anatomic reduction of the clavicle without further implant removal. It ensures vertical and horizontal stabilization of the AC joint. Using a horizontal drill hole through the clavicle and looping the gracilis tendon graft around the coracoid avoids weakening of the coracoid with the risk of fracture.

Arthroscopic-Assisted Acromioclavicular Joint Dislocation Repair: A Modified Technique for Horizontal Stabilization Using Suture Anchors.

Project description:Acromioclavicular (AC) dislocation is a common lesion often resulting from a sports injury. Nowadays, treatment is still controversial mainly in grade III lesions according to the Rockwood classification. For most surgically treated AC acute dislocations, treatment is performed with an arthroscopic procedure that anatomically reconstructs the coracoclavicular ligaments. Increasing knowledge about AC joint biomechanics has underlined the importance of its horizontal stability through the superior and inferior AC ligaments. Moreover, the pattern of lesion tends to repeat itself, with the superior AC ligament being torn most frequently from the clavicular side in a peeling fashion. Therefore, the purpose of this note is to describe the technical aspects of additional horizontal stability through superior AC ligament repair using suture anchors.

Arthroscopic Acromioclavicular Joint Treatment With Coracoclavicular Fixation and Allograft Coracoclavicular Ligament Reconstruction for Acute Acromioclavicular Dislocations.

Project description:Treatment of severe acromioclavicular joint injuries remains controversial and has evolved over the past 4-plus decades. Although several variations on reconstruction exist, an ideal technique will likely use a combination of coracoclavicular ligament reconstruction with suture backup stabilization, minimal drill holes to reduce the risk of fracture, arthroscopic-assisted guidance for anatomic graft and suture placement in and around the coracoid, and fluoroscopic-aided reduction to ensure an anatomic acromioclavicular joint. The objective of this Technical Note is to describe an arthroscopic-assisted coracoclavicular ligament reconstruction with allograft using fluoroscopically guided and cerclage-controlled anatomic reduction of the acromioclavicular joint.

Arthroscopy-Assisted All-Suture Coracoclavicular and Acromioclavicular Joint Stabilization in Acute Acromioclavicular Joint Injuries.

Project description:The existing literature agrees on surgical management for Rockwood grade IV and V injuries, but there is no consensus which type of surgery is the most appropriate one. More than 150 surgeries have been described for this condition in the literature. In an injury of less than 3 weeks, most surgeons prefer suture-button devices for coracoclavicular stabilization. Recent biomechanical studies have demonstrated that coracoclavicular stabilization provides good vertical stability but poor horizontal stability of acromioclavicular joint. Hence, they recommend acromioclavicular stabilization along with coracoclavicular stabilization. The use of a suture-button device for coracoclavicular stabilization requires special implants and instruments along with high surgical skills to drill precisely placed holes in the clavicle and the coracoid in order to avoid fractures from the drill hole. Due to relatively smaller clavicle and coracoid in Asian population, making holes in the clavicle and the coracoid has increased risk of fracture. We describe a technique in which no drill holes are made in the clavicle or the coracoid. In our technique, suture tape is used, which is looped around the coracoid and the clavicle, and the limbs are tied over the clavicle to maintain the coracoclavicular distance. The remaining limbs of suture tape is further looped through the tunnels made in acromion and tied over the acromion to augment the acromioclavicular ligament. The potential advantages of this technique are no costly implant and instruments are required, avoidance of complications associated with drill holes in coracoid and clavicle, both coracoclavicular and acromioclavicular joints are stabilized, direct repair of the acromioclavicular ligament can be performed, and no need of second surgery for implant removal.

All-Endoscopic Treatment of Acromioclavicular Joint Dislocation: Coracoclavicular Ligament Suture and Acromioclavicular Ligament Desincarceration.

Project description:Acute acromioclavicular (AC) joint dislocations are common and difficult to manage. The physiopathologic pattern begins with the rupture of the AC ligaments, then the coracoclavicular (CC) ligaments, and with an invasion of the clavicle through the deltotrapezial fascia. Therefore, we tend to perform a true suture of the CC ligaments, along with a release of the AC ligaments from the joint. We thus propose an all-endoscopic CC ligament suture and AC joint release. It starts with glenohumeral exploration enabling a repair of concomitant lesions when necessary. Dissection of the coracoid process is made, along with the lateral border of the conjoint tendon, medially the pectoralis minor tenotomy, and plexus brachial exposition and protection. Superiorly the CC ligaments are tagged and exposed. A major difference with others procedure then arises. We dissect the inferior and superior surfaces of the clavicle and the AC joint, although we maintain the continuity between the deltotrapezoid fascia and the AC ligaments. The AC dislocation is reduced under endoscopic control performing a true suture of the CC ligaments by the mean of 2 suture tapes and dog bones. After surgery, a shoulder brace is used for 6 weeks. Physiotherapy then begins.

Arthroscopic Coracoclavicular Ligament Stabilization Using Coracoid Cortical Suspension in Acute Acromioclavicular Joint Injury; Precision of Drill Tunnel.

Project description:Acute acromioclavicular joint separation is a common injury of the shoulder. There are several methods for treating this condition; however, there is no gold standard established. Herein, we propose an arthroscopic method for the treatment of acute acromioclavicular joint separation using a simple cortical suspension device at the coracoid base via a transclavicular-transcoracoidal tunnel and tieing the suture at the clavicle. This method has the advantages of making a precision drilling tunnel using small implants and small stab incisions, with better cosmetic results and less implant irritation.

Arthroscopic Acromioclavicular Joint Reconstruction Using Knotless Coracoclavicular Fixation and Soft-Tissue Anatomic Coracoclavicular Ligament Reconstruction.

Project description:Acromioclavicular joint injuries are one of the most common shoulder injuries, and there are a variety of treatment options. Recently, there have been newer arthroscopic techniques that have addressed coracoid and clavicle fracture risk by using a knotted suture-button fixation through a single, small bone tunnel with additional looped soft-tissue graft stabilization. Although clinical outcomes have been good to excellent, there have still been instances of knot and hardware irritation. The described technique builds on the latest advances and achieves an anatomic coracoclavicular (CC) reconstruction through a single knotless CC fixation device with additional soft-tissue allograft reconstruction of the CC ligaments. This technique minimizes the risks of coracoid and clavicle fractures and knot and hardware irritation while maintaining excellent stability.

Clinical outcomes of arthroscopic and navigation-assisted two tunnel technique for coracoclavicular ligament augmentation of acute acromioclavicular joint dislocations.

Project description:BackgroundThe purpose of this study was to present a navigated image-free augmentation technique for the acromioclavicular joint (ACJ) and coracoclavicular (CC) ligaments and to report the clinical and radiological outcomes.MethodsFrom 2013 to 2018, 35 eligible patients were treated with our navigated image-free ACJ- and CC-augmentation technique. The average follow-up was 3 years. Follow-up evaluations included the Constant-Murley Score, subjective shoulder value, Taft score, and the acromioclavicular joint instability (ACJI) score. The patients' quality of life was assessed using the EuroQol-5D (EQ-5D) questionnaire. In addition, in accordance with the instability criteria, radiographs were evaluated before surgery, after surgery, and during follow-up.ResultsOverall, 25 patients (71%) suffered an acute type V disruption, 5 (14%) had a type IV disruption, and 5 (14%) had an acute Rockwood type IIIb injury. The mean Constant-Murley Score was 90 (range: 56-100; p = 0.53) on the injured side, and the mean subjective shoulder value was 92% (range: 80-100%). The mean Taft and ACJI scores were 10 (range: 4-12) and 86 (range: 34-100), respectively and the mean EQ-5D was 86 (range: 2-100). The mean CC difference of the injured side was 4 mm (range: 1.9-9.1 mm) at follow-up, which was not significantly different than that of the healthy side (p = 0.06). No fractures in the area of the clavicle or the coracoid were reported.ConclusionsThe arthroscopic- and navigation-assisted treatment of high-grade ACJ injuries in an anatomical double-tunnel configuration yields similar clinical and radiological outcomes as the conventional technique using an aiming device. Precise positioning of the navigation system prevents multiple drillings, which avoids fractures.

All-Arthroscopic Technique for Reconstruction of Acute Acromioclavicular Joint Dislocations.

Project description:Acromioclavicular joint dislocations are a common injury particularly among contact sports players. There has been an increasing trend toward arthroscopic management of these injuries. To date, these reconstructions have primarily addressed superoinferior instability by reconstructing the coracoclavicular ligaments. We describe an all-arthroscopic technique for reconstruction of the coracoclavicular ligaments using Arthrex ABS TightRopes (Arthrex, Naples, FL), with additional stabilization of the superior acromioclavicular joint capsule using an anchor-based suture bridge to address anteroposterior instability.
