We present a case of concurrent rotator cuff tear and axillary nerve palsy resulting from anterior dislocation of the shoulder and a large glenoid rim fracture-a "terrible tetrad." A 61-year-old woman fell on her right shoulder. Radiographs showed anterior dislocation of the shoulder with a glenoid rim fracture, and an MRI two months after injury revealed a rotator cuff tear. Upon referral to o...

BACKGROUND There is no consensus for the optimal postoperative rehabilitation protocol after rotator cuff repairs. OBJECTIVE To determine if there is sufficient level I or II evidence available in the literature for establishment of a uniform, optimal rotator cuff rehabilitation protocol. DATA SOURCES A systematic review of level I and II English-language, prospective, randomized controlled...

BACKGROUND The etiology of rotator cuff disease is age related, as documented by prevalence data. Despite conflicting results, growing evidence suggests that distinct scapular morphologies may accelerate the underlying degenerative process. The purpose of the present study was to evaluate the predictive power of 5 commonly used radiologic parameters of scapular morphology to discriminate betwee...

The subacromial bursa is recognized as a site associated with the shoulder pain caused by rotator cuff disease in the middle-aged and elderly. Substance P is contained in primary afferent nerves, and its quantity increases during chronic pain. The amount of substance P in the subacromial bursa of patients with rotator cuff disease was examined. Radioimmunoassay and immunohistochemistry were emp...

BACKGROUND Microvascular blood flow in the tendon plays an important role in the pathogenesis of rotator cuff abnormalities. There are conflicting views about the presence of a hypovascular zone in the supraspinatus tendon. Besides, no studies have looked at the pattern of blood flow around a partial-thickness tear. Our aim was to measure microvascular blood flow in normal and a range of pathol...

When revising failed double-row and suture-bridge rotator cuff repairs medial failures represent a potential feature. In the presence of a compromised healing environment, patch augmentation becomes a logical adjunct from a mechanical and biological point of view. A reproducible step-by-step revision technique is described that reinforces the weak central cuff area with an absorbable synthetic ...

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...

Akbari A1 1. Assistant Professor, Department of Physiotherapy, Faculty of Medicine, Zahedan University of Medical Sciences Abstract Background: Shoulder pain is the third most prevalent cause of musculoskeletal disorder after low back and cervical pains. Most of the shoulder symptoms are attributed to the rotator cuff. The objective of this study was to compare the effects of low-power ...

background: magnetic resonance imaging (mri) has long been considered a perfect imaging study for evaluation of shoulder pathologies despite occasional discrepancies between mr reports and arthroscopic findings. in this study we aim to evaluate impact of imaging center as an indicator of image quality on accuracy of mri reports in diagnosis of rotator cuff tendon pathologies. methods: we review...

The incidence of acromioplasty has increased dramatically in recent decades, but its role in rotator cuff surgery has been debated. Neer popularized the extrinsic theory of rotator cuff pathology, where mechanical compression of the coracoacromial arch leads to tearing of the rotator cuff. Under this theory, acromioplasty is advocated to modify acromial morphology as an essential part of rotato...
