Background: Many surgical procedures are proposed to manage shoulder instability with recurrent dislocation but there is still a high rate of failure or complications. Repairs are often limited to anterior part of inferior glenohumeral ligament but some authors are reporting better clinical results if its posterior band is also repaired. This biomechanical study aimed to investigate the impact of a supplementary posterior injury compared with an isolated anterior injury and to analyze the contribution of a posterior repair of the inferior glenohumeral ligament compared with an isolated anterior repair.

Purpose: Optimal treatment of chronic unstable acromioclavicular (AC) joint dislocations (stage 3-5 according the Rockwood classification) is still debated. Anatomic coracoclavicular (CC) reconstruction is a reliable option in terms of two-dimensional radiographic reduction, clinical outcomes, and return to sports, but there remain concerns regarding anterior-posterior stability of the AC joint with CC ligament reconstruction alone. The aim of the present study was to describe the mid-term results of a new hybrid technique with CC and AC ligament reconstruction for chronic AC joint dislocations. Read More

Backgroud: Coracoacromial ligament transfer is the traditional procedure for treating chronic acromioclavicular separation, but it is significantly inferior to ligament reconstruction according to biomechanical and clinical studies. However, ligament reconstruction carries the risk of complications of graft loosening and peri-tunnel fractures. Currently, there is no ligament reconstruction procedure optimal for preventing such complications. Read More

Missed or chronic bilateral anterior shoulder dislocation is a rare presentation, usually secondary to epileptic attack. We present herein an exceptional case of this injury pattern, associated with bilateral displaced fracture of the coracoid process, and unilateral rupture of the long head of biceps. Treatment consisted of open reduction through osteotomy of the lesser tuberosity, with additional stabilization of the glenohumeral joint, using the Latarjet procedure by transposition of the coracoid fragment with its attached conjoint tendon to the antero-inferior glenoid rim.

Background: Glenoid lateralization has been shown to be the most imortant factor in maximizing passive range of motion and shoulder stability while preventing scapular impingement and notching. We aimed to evaluate mid- to long-term functional and radiologic outcomes after bony increased-offset-reverse shoulder arthroplasty (BIO-RSA) using a Grammont-style (medialized) humeral implant.

Methods: The study included 143 consecutive shoulders (140 patients; mean age, 72 years) treated with a BIO-RSA for rotator cuff deficiency. Read More

More than 100 surgical techniques have been described for the reconstruction of the coracoclavicular ligament complex. None of the techniques appears superior, but double-button fixation for acute high-grade acromioclavicular dislocations has become an attractive option. The clinical outcomes are good to excellent, and the return to physical activity and sport is above 90%. Read More

Background: The conventional AO hook locking compression plate (LCP) (Synthes, Solothurn, Switzerland) has only three holes for lateral fragments; therefore it is not suitable for use during the fixation of small-comminuted fragments in some cases. Recently, a novel hybrid hook LCP (TDM, Seoul, Korea) was developed to overcome this limitation. Here, we evaluated the clinical and radiologic outcomes of a novel hybrid hook LCP for Neer type V distal clavicle fractures compared to the outcomes of a conventional AO hook plate. Read More

Background: Shoulder pseudodislocation, or "drooping shoulder," presents with acute pain and deformity of the joint, with radiographs demonstrating inferior subluxation of the humeral head relative to the glenoid fossa. The diagnosis must be made promptly and distinguished from true glenohumeral dislocation, both to avoid unnecessary attempts at closed reduction and to facilitate investigation of the underlying cause, which may include septic arthritis, hemarthrosis, or other emergent etiologies. Point-of-care ultrasound (POCUS) may be useful in the evaluation of emergency department (ED) patients with suspected pseudodislocation. Read More

Purpose: This novel arthroscopic subscapular sling procedure stabilizes the shoulder using a semitendinosus graft to create a sling around the subscapular tendon, which provides both static and dynamic stability. The aim of the study was to evaluate the biomechanical stability of the subscapular sling procedure in human cadaveric shoulders. The hypothesis was that the sling offers an equal stabilizing effect and range of motion compared to an arthroscopic Bankart repair. Read More

Chronic acromioclavicular joint dislocations (ACJDs) develop when there is failure of conservative treatment, failed surgical treatment of acute ACJD, or simply missing the treatment in the acute healing phase. There is wide agreement that mechanical fixation alone in chronic ACJD is not sufficient and biological augmentation is necessary. Various arthroscopic techniques for reconstruction of the coracoclavicular ligament have been described, but allografts are expensive, are not available in all centers, carry the risk of disease transmission, and are "dead tissue" with a poor capacity for healing.

Background: Open dislocation of the glenohumeral joint is a very rare complication with only six cases described in the literature. Most cases resulted in severe complications like avascular necrosis of the humeral head or septic arthritis with poor functional results. The "mandatory" treatment of choice is surgery, with accurate debridement and reconstruction of the damaged soft tissues. Read More

Background: Nonoperative management of complete acromioclavicular (AC) joint dislocation has yielded reasonable results, although patients may report dissatisfaction with the outcome. The purpose of this prospective, randomized, controlled trial was to compare patient outcome following nonoperative care versus operative treatment with open reduction and tunneled suspension device (ORTSD) fixation for acute, type-III or IV disruptions of the AC joint.

Methods: Sixty patients aged 16 to 35 years with an acute type-III or IV disruption of the AC joint were randomized to receive ORTSD fixation or nonoperative treatment, following a power analysis to determine sample size. Read More

In the field of traumatic shoulder dislocations, this report of a 61-year-old female patient discusses the case of an acute locked superior shoulder dislocation in conjunction with a chronic rotator cuff arthropathy resulting from a low-energy fall on the outstretched and abducted arm. Radiological assessment revealed a complex combination of associated bony injuries including a fracture of the upper part of the glenoid and an impaction fracture of the inferior articular surface of the humeral head. Closed reduction and immobilisation were not successful in obtaining joint stability. Read More

Department of Orthopaedic Surgery, University of Utah, Salt Lake City, UT, USA.

Background: Instability is the most common complication after reverse total shoulder arthroplasty (rTSA). In the native glenohumeral joint, in addition to full dislocations, more subtle forms of instability exist. However, the incidence of more subtle forms of instability, the factors associated with instability, and the effect of instability on validated outcome scores after rTSA remain poorly understood.
