BACKGROUND Suprascapular nerve entrapment with isolated paralysis of the infraspinatus muscle is uncommon. However, this pathology has been reported in volleyball players. Despite a lack of scientific evidence, excessive strain on the nerve is often cited as a possible cause of this syndrome. Previous research has shown a close association between shoulder range of motion and strain on the supr...

The suprascapular nerve (SSN) emerges from the upper trunk of the brachial plexus (C5-C6) and provides the majority of the sensory innervation to the glenohumeral and acromioclavicular joints. In addition, it provides motor innervation to the supraspinatus and infraspinatus muscles [1]. Blockade of the SSN was first described in 1941 by Wertheim and Rovenstine [2] and, since then, has been used...

In inclined U-notches, the mixed mode (I + II) loading occurs and the mode ratio can be increased by varying the notch angle. In this paper, the effect of the inclined U-notch geometry, i.e. the notch depth, the notch angle, the notch root radius, and the position of the notch with respect to supports, on the mode ratio (KII/KI) have been studied. Three-point bending and plane strain condition ...

Skin thickness (epidermis-dermis) across the deltoid, suprascapular, waist and thigh as possible body sites for a new microdelivery system for intradermal (id) inoculation were evaluated using 20 MHz ultrasound echography in 205 women and 137 men aged 18-70 years, in three ethnic groups: Caucasian, Asian and Black. Mean skin thickness was 2.54 mm at the suprascapular, 2.02 mm at the deltoid, 1....

INTRODUCTION Massive rotator cuff tears may be present in patients with minimal pain and good function, or in patients with significant pain and disability.5,6,14,26 In the latter case, arthroscopic repair, either partial or complete, has been demonstrated to improve function.3,11,20,21 The mechanism of recovery is believed to be associated with an improved rotator cuff function due to at least...

Entrapment neuropathy of the suprascapular nerve (SNE), although a recognised clinical entity, is a relatively rare cause of shoulder pain and subjective weakness in the athlete involved in overhead sports like volleyball and badminton. This study deals with the presentation and management of four unusual cases of suprascapular nerve entrapment in volleyball players. Four male volleyball player...
