UNLABELLED The present study sought to identify full-thickness rotator cuff tears liable to induce an acromiohumeral distance (AHD) of less than 6 mm. The hypothesis was that, less than 6mm AHD is found exclusively in association with total full-thickness infraspinatus tear. MATERIALS A continuous single-center series recruited 109 shoulders, free of glenohumeral osteoarthritis, presenting wi...

The aim of this study was to investigate the correlation critical shoulder angle (CSA) in rotator cuff arthropathy patients with number damaged tendons and muscle fatty degeneration. Rotator were included study. True antero-posterior radiographs (Grashey view) used measure by first author. angles measured on radiographs. Magnetic resonance images (MRI) same assessed terms tendon involvements de...

AIM To evaluate whether implant design, glenoid positioning, and other factors influenced instability and scapular notching in reverse total shoulder arthroplasty. METHODS We retrospectively reviewed records of patients who had undergone reverse total shoulder arthroplasty by the senior author from July 2004 through October 2011 and who had at least 24 mo of follow-up. The 58 patients who met...

Patients with rotator cuff tears have varying degrees of symptom expression. Our purpose was to evaluate the differential firing patterns of the rotator cuff, deltoid, and scapular stabilizer muscle groups in normal control subjects and in patients with symptomatic and asymptomatic 2-tendon rotator cuff tears. Eighteen subjects were evaluated: six normal subjects and twelve with 2-tendon cuff t...

The aim of this presentation is to discuss the current literature and opinions on the biomechanics of the rotator cuff and relate this to the clinical relevance in rotator cuff tears. I intend to cover: Relate Biomechanics to Clinical Relevance 1. Cuff Mechanics 2. Tendon Anatomy – layers, microanatomy, blood supply 3. Pathomechanics of cuff tears The shoulder complex comprises 30 muscles. Thes...

BACKGROUND Calcific tendinitis can be a substantial cause of pain and dysfunction in the shoulder, and the pathophysiology is unclear. Recent studies have shown a link among nerve ingrowth, neovascularization, and pain in tendinopathy. The aim of this study was to determine whether there is evidence of neoinnervation and/or neovascularization in calcific tendinitis lesions of the shoulder. ME...

The rationale to anatomically repair this tendon is to restore the functional biomechanics of the shoulder. Clinical and imaging assessment are required before undertaking arthroscopy. In this way, associated pathologies of the biceps and labrum may be successfully addressed. The arthroscopic repair of the tendon implies to use suture anchors and reinsert the tendon itself over the footprint. R...

INTRODUCTION A new arthroscopic shoulder stabilisation procedure is proposed, which for some patients could be an alternative to the arthroscopic Latarjet procedure. METHODS The objective was to stabilize the shoulder by making a sling around the subscapularis tendon, using a hamstring graft and enhancing the anterior rim of the glenoid with the same graft. The anatomical feasibility of the s...
