Background: The clinical evaluation of the patient with shoulder instability can be challenging. The pathological spectrum ranges from the straightforward "recurrent anterior dislocation" patient to the overhead athlete with a painful shoulder but not clear instability episodes. Advances in shoulder arthroscopy and imaging have helped in understanding the anatomy and physiopathology of the symptoms. The aim of this general article is to summarize the main examination manoeuvres that could be included in an overall approach to a patient with a suspicion of instability...

We report a case of a 15-year-old boy with chronic intermittent left shoulder pain due to an undiagnosed lesser tuberosity avulsion fracture, an associated biceps pulley injury and intra-articular dislocation of the long head of the biceps tendon. Lesser tuberosity avulsion fractures are rare injuries that are difficult to detect on clinical exam and radiographically, which may lead to delayed diagnosis and chronic shoulder instability. Few reports describe dislocations or subluxations of the biceps tendon in association with lesser tuberosity avulsions in children...

TECHNIQUE: The treatment of bone defects in primary shoulder arthroplasty has evolved due to more detailed diagnostic tools, 3D planning and expanded indications for reverse shoulder arthroplasty. Glenoid bone defects combined with chronic posterior subluxation of the humeral head are gradually being treated by glenoid reconstruction and reverse implants even if the rotator cuff is still intact. The treatment of advanced bone loss due to glenoid loosening has been facilitated by bone augmentation using a cementless fixation as proposed by Norris...

PURPOSE OF REVIEW: The goal of this paper is to provide an overview in evaluating the patient with suspected or known anteroinferior glenohumeral instability. RECENT FINDINGS: There is a high rate of recurrent subluxations or dislocations in young patients with history of anterior shoulder dislocation, and recurrent instability will increase likelihood of further damage to the glenohumeral joint. Proper identification and treatment of anterior shoulder instability can dramatically reduce the rate of recurrent dislocation and prevent subsequent complications...

Background Shoulder subluxation is a common post-stroke complication affecting up to 80% of the stroke subjects. The pathomechanics at the skeletal level does not provide the structural base for the neural-motor recovery. The management of subluxed shoulder has always been a challenge, complicating the motor and functional recovery. Objective To review the available studies of rehabilitation interventions for reduction of subluxed shoulder and to explore the evidence for impact of subluxation on motor recovery...

BACKGROUND: There is a low incidence of posterior instability which is present in only 2% to 10% of all unstable shoulders. The posterior instable shoulder includes different manifestations like fixed dislocation, recurrent subluxation or dislocation. METHODS: Research and online content related to posterior instability is reviewed. Natural history, clinical evaluation and imaging are described. RESULTS: An awareness of the disorder, together with a thoughtful evaluation, beginning with the clinical history, usually leads to proper diagnosis...

BACKGROUND: Failed shoulder instability surgery is mostly considered to be the recurrence of shoulder dislocation but subluxation, painful or non-reliable shoulder are also reasons for patient dissatisfaction and should be considered in the notion. METHODS: The authors performed a revision of the literature and online contents on evaluation and management of failed shoulder instability surgery. RESULTS: When we look at the reasons for failure of shoulder instability surgery we point the finger at poor patient selection, technical error and an additional traumatic event...

BACKGROUND: It is estimated that approximately 5% of glenohumeral instabilities are posterior. There are a number of controversies regarding therapeutic approaches for these patients. METHODS: We analyse the main surgery alternatives for the treatment of the posterior shoulder instability. We did a research of the publications related with posterior glenohumeral instability. RESULTS: There are conservative and surgical treatment options. Conservative treatment has positive results in most patients, with around 65 to 80% of cases showing recurrent posterior dislocation...

BACKGROUND: The delayed management of patients with shoulder instability may increase the prevalence and severity of concomitant intra-articular shoulder injuries resulting from persistent subluxations and dislocations. HYPOTHESIS: Patients with a longer delay from the initial dislocation event to undergoing magnetic resonance imaging (MRI) or magnetic resonance arthrography will demonstrate more subluxations or dislocations and a greater amount of intra-articular shoulder damage...

REVIEW
Peter Domos, Caio Santos Checchia, Gilles Walch
The management of primary osteoarthritis of the shoulder has been well investigated. However, the etiology and management of posterior humeral head subluxation in the context of primary glenohumeral osteoarthritis remain controversial. The finding of static posterior subluxation of the humeral head before the development of posterior bone erosion of the glenoid in young men with radiographic findings of primary osteoarthritis has been described as arthrogenic posterior subluxation of the humeral head. It demonstrates the earliest form of the osteoarthritic evolution, and an excessive glenoid retroversion is the only probable cause of this static subluxation, although this is controversial...

HYPOTHESIS: We hypothesized that National Football League (NFL) players sustaining a shoulder destabilizing injury could return to play (RTP) successfully at a high rate regardless of treatment type. METHODS: We identified and evaluated 83 NFL players who sustained an in-season shoulder instability event while playing in the NFL. NFL RTP, incidence of surgery, time to RTP, recurrent instability events, seasons/games played after the injury, and demographic data were collected...

BACKGROUND: Flail shoulder can occur following a brachial plexus injury and is characterized by painful subluxation of the glenohumeral joint and the inability to independently position the hand in space. The present study aimed to report the clinical outcomes following glenohumeral arthrodesis for late reconstruction of flail shoulder in patients with traumatic supraclavicular brachial plexus palsy. METHODS: Seven patients were included in the present study and were followed-up for a mean of 98 months (range 27 months to 197 months)...

BACKGROUND: Shoulder dislocation is often the first symptom of Ehlers-Danlos syndrome (EDS). Whether it occurs in early-onset EDS is unknown. In most cases, surgical failure leads to the diagnosis. We aimed to determine whether clinical symptoms can signal the presence of EDS at a first dislocation. MATERIALS AND METHODS: In this retrospective study, we analyzed clinical and radiologic data for 27 patients with EDS and shoulder instability and a control population of 40 consecutive non-EDS patients undergoing surgery for an unstable shoulder...

In posterior shoulder instability (recurrent dislocation, involuntary posterior subluxation or voluntary subluxation that has become involuntary), surgery may be considered in case of failure of functional treatment if there are no psychological contraindications. Acromial bone-block with pediculated deltoid flap, as described by Kouvalchouk, is an alternative to iliac bone-block, enabling triple shoulder locking by the blocking effect, the retention hammock provided by the deltoid flap and posterior capsule repair...

BACKGROUND: The management of posterior shoulder instability remains controversial. Consequently, for a symposium on this topic, the French Arthroscopy Society (SFA) conducted a prospective multicentre study comparing outcomes of operative and non-operative treatment. OBJECTIVE: To compare outcomes after operative versus non-operative treatment of posterior shoulder instability. HYPOTHESIS: The surgical treatment of posterior shoulder instability may achieve better clinical outcomes than non-operative treatment in selected patients...

BACKGROUND: Painful posterior shoulder instability (PPSI) is the least common of the three clinical patterns of posterior shoulder instability. PPSI is defined as pain combined with anatomical evidence of posterior instability but no instability events. MATERIAL AND METHOD: We studied a multicentre cohort of 25 patients with PPSI; 23 were identified retrospectively and had a follow-up of at least 2 years and 2 patients were included prospectively. Most patients engaged in sports...

BACKGROUND: Functional shoulder instability (polar type III) is caused by underactivity of rotator cuff and periscapular muscles, which leads to subluxation or dislocation during shoulder movement. While surgical treatment has shown no benefits, aggravates pain, and frequently diminishes function even further, conservative treatment is often ineffective as well. OBJECTIVES: The aim was to investigate the effectiveness of a "shoulder pacemaker" device that stimulates underactive muscles in patients with functional instability during shoulder movement in order to re-establish glenohumeral stability...
