BACKGROUND: The synergistic effect of the acromioclavicular (AC) capsule and coracoclavicular (CC) ligaments on AC joint stability has gained recent recognition for its importance. Biomechanical and clinical studies have shown the benefit of combined reconstruction with multiple variations of surgical techniques for AC capsule augmentation. The ideal configuration remains unknown for such capsular repair aimed at achieving optimal stability with anatomic reconstruction. HYPOTHESIS: Primary AC joint stability can be restored by AC capsule augmentation, while position of the additional suture construct is critical...

PURPOSE: To introduce an arthroscopically assisted coracoclavicular (CC) fixation technique using multiple low-profile devices to evaluate the clinical and radiologic outcomes in patients with acute high-grade acromioclavicular (AC) joint dislocation. METHODS: Between July 2014 and September 2015, cases of AC joint dislocation that were treated with arthroscopic CC fixation using multiple low-profile devices with a minimum follow-up of 24 months were included. We measured the vertical coracoclavicular distance (CCD) on the anteroposterior view and the horizontal acromioclavicular distance on 3-dimensional computed tomography images to evaluate the changes in radiologic outcomes before and after surgery...

BACKGROUND: Acromioclavicular joint dissociation may not be a common injury, yet it may cause limitations in activity. Types IV, V, and VI dissociations need operative repair. In this study, a simple technique is advocated to reduce and maintain reduction of the acromioclavicular joint using no. 5 nonabsorbable suture material while the resutured coracoclavicular (CC) ligament heals. METHODS AND METHODS: Twenty-one patients (16 men and five women) with types IV and V acromioclavicular joint dissociation were studied...

BACKGROUND: Currently, no clinical midterm results have been reported on arthroscopically assisted reduction of the acutely dislocated acromioclavicular (AC) joint using suture-button devices for fixation. HYPOTHESIS: Athroscopically assisted reduction of the acutely dislocated AC joint yields satisfactory clinical outcomes without loss of reduction, clavicle migration, or AC joint degeneration at midterm follow-up evaluation. STUDY DESIGN: Case series; Level of evidence, 4...

PURPOSE: We described a novel all-arthroscopic technique of coracoclavicular ligament reconstruction and reported the early clinical and radiologic results of this procedure. METHODS: We performed all-arthroscopic coracoclavicular ligament reconstruction in 10 consecutive patients (8 men and 2 women; mean age, 41 years) with a symptomatic chronic and complete acromioclavicular (AC) joint dislocation (Rockwood type III or IV). Four patients had undergone surgery previously: two had initial pinning of the acute AC joint separation, and two had a subsequent Mumford procedure...

INTRODUCTION: Numerous static and dynamic techniques have been described for the management of acute acromioclavicular (AC) joint dislocation. To date, no standard technique has been established and several complications have been described for each of these techniques. The purpose of the present study was to evaluate the functional and radiographic outcomes of acute AC joint reconstruction after a mini-open technique using the double-button fixation system. PATIENTS AND METHODS: Twelve patients with acute AC joint dislocation treated with the double-button fixation system by one surgeon were retrospectively reviewed...

Shoulder injuries, including acromioclavicular (AC) joint separations, remain a common reason for presentation to the emergency room. Although the diagnosis can be made apparent through proper history and physical examination by the emergency medicine physician, ascertaining the degree of injury can be difficult on the basis of clinical evaluation alone. While there is consensus in the literature that low-grade AC joint injuries can be treated with conservative management, high-grade injuries will generally require surgical intervention...

BACKGROUND: Dislocation of the acromioclavicular joint is one of the most common shoulder problems in general orthopaedic practice. The question of whether surgery should be used remains controversial. OBJECTIVES: To assess the relative effects of surgical versus conservative (non-surgical) interventions for treating acromioclavicular dislocations in adults. SEARCH STRATEGY: We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (to February 2009), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2009, Issue 1), MEDLINE (1966 to February 2009), EMBASE (1988 to February 2009), and LILACS (1982 to February 2009), trial registries and reference lists of articles...

Acromioclavicular (AC) joint injuries are common in athletic populations and account for 40% to 50% of shoulder injuries in many contact sports, including lacrosse, hockey, rugby and football. The AC joint is stabilized by static and dynamic restraints, including the coracoclavicular (CC) ligaments. Knowledge of these supporting structures is important when identifying injury and directing treatment. Management of AC injuries should be guided by severity of injury, duration of injury and symptoms, and individual patient factors...

The aim of this review is to address controversies in the management of dislocations of the acromioclavicular joint. Current evidence suggests that operative rather than non-operative treatment of Rockwood grade III dislocations results in better cosmetic and radiological results, similar functional outcomes and longer time off work. Early surgery results in better functional and radiological outcomes with a reduced risk of infection and loss of reduction compared with delayed surgery. Surgical options include acromioclavicular fixation, coracoclavicular fixation and coracoclavicular ligament reconstruction...

BACKGROUND: Whilst there is little debate over the treatment of Rockwood grade V and VI acromioclavicular dislocation, the management of grade III acromioclavicular dislocation remains less clear. The purpose of this study was to compare the clinical outcomes of patients managed operatively and non-operatively following grade III acromioclavicular dislocation. MATERIALS AND METHODS: A systematic review of published and unpublished material was conducted. All included studies were reviewed against the PEDro appraisal tool...

Injuries to the acromioclavicular joint are common but underdiagnosed. Sprains and minor subluxations are best managed conservatively, but there is debate concerning the treatment of complete dislocations and the more complex combined injuries in which other elements of the shoulder girdle are damaged. Confusion has been caused by existing systems for classification of these injuries, the plethora of available operative techniques and the lack of well-designed clinical trials comparing alternative methods of management...

BACKGROUND: Operative treatment of acromioclavicular joint injuries is recommended for higher degree dislocations. Recently a new option has become available with the minimally-invasive tight rope technique. Whereas clinical studies justify the medical use, risks and benefits remain unclear. Therefore, this study analyzed these facts associated with this procedure and compared them to K-wire fixation. MATERIAL AND METHODS: A retrospective analysis was performed of patients surgically treated either with the TightRope™-technique (TR) or K-wires (KW) for a first event isolated Rockwood type III or higher acromioclavicular joint dislocation between 2004 and 2011...

BACKGROUND AND PURPOSE: Long-term outcome after surgery for grade-V acromioclavicular joint dislocation has not been reported. We performed a retrospective analysis of functional and radiographic outcome 15-22 years after surgery. PATIENTS AND METHODS: We examined 50 patients who were treated at our hospital between April 1985 and December 1993. Various methods of stabilization were used: K-wires (n = 36), 4.5-mm screw (n = 12), or biodegradable screw (n = 2). Osteosynthesis material was removed after 6-8 weeks...

PURPOSE: To conduct a systematic review of the literature in relation to 3 considerations in determining treatment options for patients with acromioclavicular (AC) joint dislocations: (1) operative versus nonoperative management, (2) early versus delayed surgical intervention, and (3) anatomic versus nonanatomic techniques. METHODS: The PubMed database was searched in October 2011 using the single term acromioclavicular and the following search limits: any date, humans, English, and all adult (19+)...

Acromioclavicular joint (ACJ) separation injuries are common injuries among sporting populations. ACJ separations are graded according to severity from grade I being a mild sprain to grade VI, which is severe dislocation with displacement. There is consensus in the literature that grade I-III ACJ separations are managed conservatively and grades IV-VI are managed surgically. Despite conservative care being recommended for lesser grades of injury, there is very little evidence in the literature as to what constitutes conservative care...
