OBJECTIVE: The purpose of this study was to describe the 3-dimensional deformities of midshaft clavicle fractures, which had been treated nonoperatively, using computed tomography (CT) surface matching. METHODS: Twenty-one patients with unilateral midshaft clavicle fracture, who had been treated nonoperatively, were enrolled and evaluated retrospectively. The 3-dimensional deformity of the fractured clavicle was evaluated by CT surface matching. CT scans of 21 age- and sex-matched patients with initial traumatic shoulder dislocation or proximal humeral fracture were enrolled as a control group, and the differences in 3-dimensional deformities and lengths of the clavicles between the fracture group and the control group were evaluated...

BACKGROUND: Although recent evidence suggests that any prior shoulder surgery may cause inferior shoulder arthroplasty outcomes, there is no consensus on whether previous rotator cuff repair (RCR) is associated with inferior outcomes after reverse total shoulder arthroplasty (RTSA). PURPOSE: To retrospectively compare outcomes in patients who underwent RTSA with and without previous RCR. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Patients with prior RCR and those without previous shoulder surgery (control) who underwent RTSA for cuff tear arthropathy or irreparable cuff tear were retrospectively identified from a prospective database...

INTRODUCTION: The literature review revealed that nowadays only about 15 cases of bilateral shoulder dislocation associated with the fracture of the upper end of the humerus have been published. The triad of lesional mechanism designated by the triple syndrome E composed of epilepsy, electrocution, and external trauma was the circumstances noted in which these fractures dislocations occur with migration of the two humeral heads either forward or backward. CASE REPORT: An architect of 36-year-old, right-handed, was admitted in emergency department for loss of knowledge of progressive installation...

BACKGROUND: The recommended initial treatment for multidirectional instability (MDI) of the shoulder is a rehabilitation program, yet there is very low-quality evidence to support this approach. Purpose/Hypothesis: The purpose was to compare the Watson MDI program and Rockwood Instability program among patients with nontraumatic, nonstructural MDI. The hypothesis was that the Watson MDI program would produce clinically and statistically superior outcomes over the Rockwood Instability program...

INTRODUCTION: The Cunningham technique has been shown to be an effective and simple method to reduce a dislocated shoulder. It is based on the theory that the humeral head remains outside the glenoid fossa due to tension in the long biceps tendon. In the beginning of 2013 doctors at the emergency department in Landspitali University Hospital (LUH) in Reykjavik were instructed in the Cunningham method for reduction of anterior dislocation without sedation. The goal of this retrospective study was to evaluate the impact of its induction with regards to number of attempts, successful relocations, sedation, use of analgesics and length of stay in the ED...

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 rotational muscles act as dynamic stabilizers of the glenohumeral joint, and the recovery of muscle strength plays an important role in stabilizing the joint during postoperative rehabilitation. However, temporal changes in muscle strength after arthroscopic Bankart repair have not been clarified. PURPOSE: To better understand the temporal recovery of shoulder rotational muscle strength after arthroscopic Bankart repair. STUDY DESIGN: Case series; Level of evidence, 4...

PURPOSE OF THE REVIEW: The goal of this review is to provide a guide on surgical decision-making options for complex anterior shoulder instability using a case-based approach. RECENT FINDINGS: Arthroscopic Bankart repair is well documented for having successful outcomes in patients with isolated labral tear involvement with minimal bone loss. Latarjet is a generally accepted procedure in patients with 20-30% glenoid bone loss. When bone loss exceeds that which cannot be managed through Latarjet, a range of options exist and are highly dependent upon the extent of osseous deficiency on both the glenoid and humeral sides, surgeon experience, and patient-specific factors...

INTRODUCTION: Powerful contractions during epileptic seizures may cause shoulder dislocation and instability. The aim of the study is to evaluate the functional and radiographic results of the Latarjet procedure for anterior shoulder dislocation in patients with epilepsy and compare the functional results of these patients with the results of patients without epilepsy. HYPOTHESIS: Is latarjet procedure effective in epileptic patients as non-epileptic patients with anterior shoulder instability? MATERIAL AND METHOD: 11 shoulders of 9 patients with epileptic seizures causing anterior shoulder instability were evaluated retrospectively...

BACKGROUND: Bony deficiency of the anteroinferior glenoid rim as a result of a dislocation can lead to recurrent glenohumeral instability. These lesions, traditionally treated by open techniques, are increasingly being treated arthroscopically as our understanding of the pathophysiology and anatomy of the glenohumeral joint becomes clearer. Different techniques for arthroscopic management have been described and continue to evolve. While the success of the repair is surgeon dependent, the recent advances in arthroscopic shoulder surgery have contributed to the growing acceptance of arthroscopic reconstruction of glenoid bone defects to restore stability...

BACKGROUND: There is no universally accepted definition of "contact" or "collision" sports in the literature. The few available studies evaluating contact and collision sports consider them to be synonymous. However, athletes in collision sports purposely hit or collide with each other or with inanimate objects with greater force and frequency than in contact sports, which could jeopardize functional outcomes. PURPOSE: To compare the functional outcomes, return to sports, and recurrences in a series of contact and collision athletes with a first-time anterior shoulder dislocation treated using arthroscopic stabilization with suture anchors...

BACKGROUND: A Hill Sachs lesion is a posterior-superior bony defect of the humeral head caused by a compression of the hard glenoid rim against the soft cancellous bone in the context of an anterior instability episode. The presence of these humeral defects increases with the number of dislocations and larger lesions are associated with a greater chance of development of recurrent instability and recurrence after surgery. Also its location and pattern, in particular the so-called engaging Hill-Sachs, are associated with poor prognosis...

BACKGROUND: The glenohumeral joint is a ball-and-socket joint that is inherently unstable and thus, susceptible to dislocation. The traditional and most common anatomic finding is the Bankart lesion (anterior-inferior capsule labral complex avulsion), but there is a wide variety of anatomic alterations that can cause shoulder instability or may be present as a concomitant injury or in combination, including bone loss (glenoid or humeral head), complex capsule-labral tears, rotator cuff tears, Kim´s lesions (injuries to the posterior-inferior labrum) and rotator interval pathology...

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: The shoulder is the most complex joint in the body. The large freedom of motion in this joint is the main cause of instability. Instability varies in its degree, direction, etiology and volition and there is a large spectrum of conditions. METHODS: Based on literature research and also in our own experience, we propose to elucidate the reader about the natural history of instability and its importance for the appropriate management of this pathology, by answering the following questions: What happens in the shoulder after the first dislocation? Which structures suffer damage? Who are the patients at higher risk of recurrence? How does the disease evolve without treatment? Will surgical treatment avoid future negative outcomes and prevent degenerative joint disease? Who should we treat and when? RESULTS: 80% of anterior-inferior dislocations occur in young patients...

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: Traumatic anterior instability of the shoulder is a common condition associated with a high recurrence rate in young adults. Operative treatment reduces the risk of recurrence. Several studies have compared arthroscopic and open shoulder instability repair. The purpose of this paper is to perform a review of the literature where both techniques are compared in the repair of the anterior shoulder instability without bone loss. METHODS: Prior to arthroscopy, recurrent dislocations were managed by open repair...

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...
