The suprascapular nerve originates from the upper trunk of the brachial plexus or less frequently from the root of C5. It runs a short way and crosses the suprascapular notch. It innervates the supraspinatus muscle and the acromioclavicular and glenohumeral joints. Then, it crosses the lateral edge of the spine of the scapula passing through the spinoglenoid notch, and innervates the infraspina...

We describe a case of suprascapular nerve entrapment caused by protrusion of an intraosseous ganglion of the glenoid into the spinoglenoid notch. A 47-year-old man with left shoulder pain developed an intraosseous cyst in the left glenoid, which came into contact with the suprascapular nerve. The area at which the patient experienced spontaneous shoulder pain was innervated by the suprascapular...

The concept of the study was to find the correlation between the morphometry of the suprascapular notch and basic anthropometric measurements of the human scapula. The measurements of the human scapulae included: morphological length and width, maximal width and length projection of scapular spine, length of acromion, and maximal length of the coracoid process. The glenoid cavity was measured i...

Arthroscopic suprascapular nerve decompression at the suprascapular notch is a technically demanding surgical procedure with a steep learning curve. The aim of this Technical Note is to describe important pearls for an arthroscopic decompression of the suprascapular nerve relying on the palpation of the coracoclavicular ligaments before starting the arthroscopic visualization. This reduces the ...

The objective of this study was to measure the maximum superior and inferior lengths of the suprascapular notch with the help of a Vernier caliper and to classify the notches accordingly into four types. This is an observational study, conducted from January to December 2009 at Islamic International Medical College, Rawalpindi. Two hundred and fifty dried human scapulae were procured and measur...

Anatomical textbooks usually cite the thyrocervical trunk, which arises from the first part of the subclavian artery, as the most common origin of the suprascapular artery [1, 2]. Variations concerning the origin of the suprascapular artery are rare but have been documented arising from all three parts of the subclavian artery, the costocervical trunk, the axillary artery, and the internal thor...

Compression of SupraScapular Nerve (SSN) was first described by Thomas in 1936 (Thomas 1936). However, Thompson and Kopell described SupraScapular Nerve (SSN) entrapment occurring at the transverse scapular notch (Thompson and Kopell 1959). Aiello et al differentiated between entrapment of this nerve at the Suprascapular notch and entrapment at the Spinoglenoid notch (Aiello, Serra et al. 1982)...

BACKGROUND The existence of sensory branches of the suprascapular nerve (SSN) has recently been reported, and sensory disturbance at the lateral and posterior aspect of the shoulder has been focused on as a symptom of SSN palsy. We have performed arthroscopic release of SSN at the suprascapular notch in patients with sensory disturbance since 2006. The purposes of this study were to introduce t...

BACKGROUND In this article, we describe a case report of using real-time, high-resolution ultrasound guidance to facilitate blockade of the suprascapular nerve. We describe a case report and technique for using a portable ultrasound scanner (38 mm broadband (13-6 MHz) linear array transducer (SonoSite Micromaxx SonoSite, Inc. 21919 30th Drive SE Bothwell W. A..)) to guide suprascapular nerve bl...

INTRODUCTION The concept of the study was to compare the morphometry of the suprascapular notch (SSN) in females and males because its size and shape may be a factor in suprascapular nerve entrapment. MATERIAL AND METHODS The measurements of 81 scapulae included morphological length and width, maximal width and length projection of the scapular spine, and width and length of the glenoid cavit...
