REVIEW
L Nové-Josserand, P Clavert
Glenoid exposure is agreed to be a difficult step, but is also a key step in total shoulder arthroplasty, both anatomic and reverse. It conditions unhindered use of the ancillary instrumentation and thus correct glenoid component positioning. The main stages comprise arthrotomy, by opening the rotator cuff, humeral head cut, and inferior glenohumeral release, enabling shifting of the humerus and good exposure of the glenoid cavity. The two main approaches are deltopectoral and anterosuperior transdeltoid. Using the deltopectoral approach, arthrotomy is performed through the subscapularis muscle, by various techniques...

BACKGROUND: Biomechanical and clinical success of the superior capsule reconstruction (SCR) using fascia lata (FL) grafts has been reported. In the United States, human dermal (HD) allograft has been used successfully for SCRs; however, the biomechanical characteristics have not been reported. METHODS: Eight cadaveric shoulders were tested in 5 conditions: (1) intact; (2) irreparable supraspinatus tear; (3) SCR using FL allograft with anterior and posterior suturing; (4) SCR using HD allograft with anterior and posterior suturing; and (5) SCR using HD allograft with posterior suturing...

Paul Sethi, Wm Grant Franco
Massive, irreparable rotator cuff disease is a challenging problem to treat, especially in the younger active patient. This condition allows the deltoid to generate anterosuperior translation and shoulder dysfunction. Ideally, this dysfunction may be improved with rotator cuff repair. However, in the setting of irreparable rotator cuff disease, normal function is challenging to restore. Superior capsule reconstruction theoretically improves function by recentering the humeral head and improving glenohumeral kinematics...

CONTEXT: Following a baseball pitching bout, changes can occur to glenohumeral range of motion that could be linked to injury. These effects are in part due to the posterior shoulder's eccentric muscle activity, which can disrupt muscle contractile elements and lead to changes in muscle cross sectional area (CSA), as measured by ultrasound. OBJECTIVE: To assess changes in muscle CSA, and range of motion immediately before and after pitching, and days 1-5 following pitching...

BACKGROUND: Glenohumeral dislocation is the most commonly encountered adult joint instability. The epidemiology in the United Kingdom and worldwide is unclear and often limited to young, active groups that are not representative of general populations. Information regarding epidemiology and outcome from a first dislocation is useful for trauma service planning and patient counseling. We calculated the incidence of shoulder instability after a first dislocation in our urban population and investigated predictors of recurrent instability...

BACKGROUND: Both anatomic (TSA) and reverse total shoulder arthroplasty (RTSA) are common interventions for glenohumeral arthrosis, with the goal of relieving pain and restoring mobility. Understanding shoulder arthroplasty motion and frequency is of interest in evaluating effectiveness and in predicting bearing wear for implant development and optimization. The purpose of this study was to measure and compare the total daily shoulder motion of patients after TSA and RTSA. METHODS: Thirty-six human subjects who had undergone shoulder arthroplasty wore a custom instrumented garment that tracked upper extremity motion for the waking hours of 1 day...

BACKGROUND: Current evidence suggests that corticosteroid injection alone expedites the recovery of pain-free ROM in patients with adhesive capsulitis compared to physiotherapy or placebo. However, it remains unclear whether the addition of hydrodilatation with corticosteroid provides improvement in pain-free ROM as well as pain relief. OBJECTIVE: Review the literature to determine whether the combined intervention of hydrodilatation and corticosteroid injection expedites restoration of pain-free range of motion (ROM) compared to a control of corticosteroid injection in patients with adhesive capsulitis...

BACKGROUND: Acromioclavicular joint (ACJ) dislocations are common injuries of the shoulder associated with physical activity. The diagnosis of concomitant injuries proves complicated due to the prominent clinical symptoms of acute ACJ dislocation. Because of increasing use of minimally invasive surgery techniques concomitant pathologies are diagnosed more often than with previous procedures. METHODS: The aim of this study was to identify the incidence of concomitant intraarticular injuries in patients with high-grade acromioclavicular separation (Rockwood type III - V) as well as to reveal potential risk constellations...

Background: Quantifying glenohumeral bone loss is key in preoperative surgical planning for a successful Bankart repair. Hypothesis: Simple radiographs can accurately measure bone defects in cases of recurrent shoulder instability. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: A true anteroposterior (AP) view, alone and in combination with an axillary view, was used to evaluate the diagnostic properties of radiographs compared with computed tomography (CT) scan, the current gold standard, to predict significant bone defects in 70 patients...

Glenoid rim fractures, accompanied by acute glenohumeral dislocation or subluxation usually results in persistent instability. Traditionally open reduction and internal fixation has been recommended in displaced intra-articular glenoid fractures. However, open reduction is difficult, and it may not be possible to address the associated intra-articular soft-tissue injuries. A few reports of arthroscopic-assisted fixation of these fractures have been recently published. The most anatomic method for addressing an acute glenoid rim lesion is a reduction (either open or arthroscopic) and internal fixation...

Background: Arthroscopy has rapidly transformed the treatment of anterior shoulder instability over the past 30 years. Development of arthroscopic equipment has permitted the investigation and diagnosis of the unstable shoulder, and fixation methods have evolved to promote arthroscopy from an experimental procedure to one of first-line mainstream treatment. Methods: Key research papers were reviewed to identify the fundamental principles in patient diagnosis and appropriate selection for arthroscopic treatment...

Referral for shoulder joint replacement in patients with glenohumeral arthrosis may be delayed in the primary sector. When non-surgical first-line treatment has little effect on pain and quality of life, patients should be referred for orthopaedic specialist assessment. New trends regarding shoulder prosthesis are under way as indicated by data from the Danish Shoulder Alloplasty Registry from the latest decade with an increase in number and quality. Changed demographic composition in favour of the elderly makes focus on the importance of shoulder prosthesis regarding research and treatment algorithm...

The labrum contributes to passive glenohumeral joint stability. Cadaveric studies have demonstrated that this has position and load dependency, which has not been quantified under physiological loads. This study aims to validate subject-specific finite element (FE) models against in vitro measurements of joint stability and to utilise the FE models to predict joint stability under physiological loads. The predicted stability values were within ± one standard deviation of experimental data and the FE models showed a reduction in stability of 10-15% with high, physiological, loads...

BACKGROUND: Brachial plexus injury is a complex entity that often results in partial recovery. Most studies to date have focused on improving shoulder abduction. However, a recent technique has been outlined-one that transfers the lower trapezius to improve the external rotation of the shoulder. The primary objective of this study was to evaluate the gains in external rotation of the shoulder in patients who have undergone transfer of the lower trapezius; secondarily, we assessed the range of motion in the elbow and shoulder joints, as well as the muscle strength and quality of life...
