INTRODUCTION: Surgical indication for acromioclavicular joint (ACJ) injuries still represents a reason for shoulder and trauma debate. In high-grade injuries, surgery is advocated because some of the non-operatively managed patients may have persistent shoulder pain that could make them unable to return to their previous activity. It has been shown that many of the patients with high-grade ACJ injuries that are managed non-operatively involve the development of scapular dyskinesis, situation that may result in loss of strength and weakness...

INTRODUCTION: The clavicle, humerus and acromioclavicular (AC) joint separately are very commonly involved in traumatic injuries around the shoulder. Acromioclavicular joint dislocation with distal clavicle fracture is a well recognized entity in clinical practice. AC joint dislocation with mid shaft clavicle fracture is uncommon and only few cases have been reported in literature. However, to the best of our knowledge, this is the first case report to describe an acromioclavicular dislocation with ipsilateral mid shaft clavicle, mid shaft humerus and coracoid process fracture...

We observed the clinical course, in the short-medium term, of patients with voluminous type II acromio-clavicular (AC) joint cyst who underwent aspiration and steroid injection regarded as the only possible treatment to avoid possible skin complications. Four patients (7.4% of cases described in literature) (3F-1M ; mean age 83 years, range : 78-87 years) with a voluminous ( > 7 cm) oval, no mobile, no fluctuant cyst overlying the AC joint, were retrospectively observed. The patients, judged by the anesthesiologist as ASA 3-4 patients, were merely submitted to cyst aspiration and steroid injection...

Traumatic glenohumeral joint dislocation and acromioclavicular joint subluxations tend to occur in young active males. Use of the coracoid process either as a transfer in recurrent instability or in suspensory reconstructions of the coracoclavicular ligaments have gained popularity. However this requires careful consideration in the event of concomitant injuries if they both require surgery.

Stabilizing the acromioclavicular joint in the vertical and horizontal planes is challenging, and most current techniques do not reliably achieve this goal. The BiPOD repair is an arthroscopically assisted procedure performed with image intensifier guidance that reconstructs the coracoclavicular ligaments as well as the acromioclavicular ligaments to achieve bidirectional stability. Repair is achieved with a combination of 2-mm FiberTape (Arthrex, Naples, Florida) and 20-mm Poly-Tape (Neoligaments, Leeds, England) to achieve rigid repair, prevent bone abrasion, and promote tissue ingrowth...

Acromioclavicular joint separations are a common cause of shoulder pain in the young athletic population. In high-grade injuries, acromioclavicular joint reconstruction procedures may be indicated for functional improvement. There is currently no gold standard for the surgical management of these injuries. Multiple reconstructive options exist, including coracoclavicular screws, hook plates, endobutton coracoclavicular fixations, and anatomic ligament reconstructions with tendon grafts. This article aims to review pertinent acromioclavicular joint anatomy and biomechanics, radiographic evaluation, classification system, as well as reconstruction options, outcomes, and complications...

OBJECTIVES: To define when an ultrasound examination of the shoulder can be considered complete and how many examinations currently performed in Italy are actually complete according to that definition. MATERIALS AND METHODS: Reports and images of previously performed ultrasound examinations of the shoulder of patients seen in 2014 for interventional procedures were reviewed for the following items, according to guidelines published by the European Society of Musculoskeletal Radiology: long biceps, subscapularis, supraspinatus, external rotators, acromioclavicular joint, subacromial bursa, subacromial space, coraco-acromial ligament, and the posterior recess...

BACKGROUND: Horizontal instability impairs clinical outcome following acute acromioclavicular joint (ACJ) reconstruction and may be caused by insufficient healing of the superior acromioclavicular ligament complex (ACLC). However, characteristics of acute ACLC injuries are poorly understood so far. Purposes of this study were to identify different ACLC tear types, assess type-specific prevalence and determine influencing cofactors. METHODS: This prospective, cross-sectional study comprised 65 patients with acute-traumatic Rockwood-5 (n = 57) and Rockwood-4 (n = 8) injuries treated operatively by means of mini-open ACJ reduction and hook plate stabilization...

PURPOSE: The aim of this study was to evaluate the outcome of a minimally invasive surgical technique for the treatment of patients with acromioclavicular joint dislocation. METHODS: Sixteen patients with complete acromioclavicular joint dislocation were enrolled in this study. All patients were asked to follow the less active rehabilitation protocol post-operatively. Computed tomography with 3-D reconstruction of the injured shoulder was performed on each patient post operatively for the assessment of the accuracy of the suture anchor placement in the coracoid process and the reduction of the acromioclavicular joint...

BACKGROUND: Recent biomechanical and clinical studies have demonstrated the effectiveness of suture button and pulley-type fixations for surgical treatment of acromioclavicular instability. Concerns remain that such procedures can "overconstrain" (overreduce the lateral clavicle in relation to the acromion to a nonphysiological position) the joint. PURPOSE/HYPOTHESIS: The purpose of this study was to investigate the intra-articular pressure of native and reconstructed acromioclavicular (AC) joints in relation to the configuration of the joint...

BACKGROUND: There has been a trend to reconstruct the coracoclavicular (CC) ligaments anatomically for management of acromioclavicular (AC) joint dislocations. PURPOSE: The aim of this study was to determine the location and orientation of the CC ligaments for anatomic reconstruction of the AC joint. METHODS: The subjects were a total of 40 shoulders from 20 Chinese cadavers. Two K-wires were drilled through the insertion center of the conoid and trapezoid ligaments respectively...

OBJECTIVE: The aim of this study was to compare the therapeutic efficacy of high-power pain threshold (HPPT) ultrasound therapy applied to the trigger points and dry needling (DN) in myofascial pain syndrome. DESIGN: Sixty-one patients were randomly assigned to an HPPT (n = 30) and dry needling (n = 31) groups. The primary outcome measures were the Visual Analog Scale (VAS) and Neck Pain and Disability Scale (NPDS), both at 1 week and 4 weeks after treatment. The secondary outcome measures were the number of painful trigger points, range of the tragus-acromioclavicular joint, the Short Form-36, the Beck Depression Inventory, the Beck Anxiety Inventory, and sonoelastographic tests after a 1-week treatment...

This review article describes injuries that occur in the upper extremities of athletes less commonly than those typically discussed with shoulders and elbows. A survey of osseous, musculotendinous, ligamentous, and neurovascular injuries is presented along with associated imaging findings and standard treatment options. This article does not focus on the classic throwing injuries of the shoulder or elbow; the goal is to survey injuries in throwing sports that involve structures away from the glenohumeral, acromioclavicular, or elbow joints...

Surgical management of acute unstable acromioclavicular joint injuries should be focused on realigning the torn ends of the ligaments to allow for healing potential. The most widely utilized treatment methods incorporate the use of metal hardware, which can alter the biomechanics of the acromioclavicular joint. This leads to a second surgical procedure for hardware removal once the ligaments have healed. Patients with unstable acromioclavicular joint injuries managed with arthroscopy-assisted procedures have shown good and excellent clinical outcomes, without the need for a second operation...
