The purpose of this study was to document the DSN's anatomy and measure the oblique course it takes with regard to the middle scalene muscle to improve clinicians' ability to locate the site of DSN entrapment so that appropriate management can be implemented. 2005;57:120-7. Your message has been successfully sent to your colleague. This case implies that combined suprascapular neuropathy might contribute to scapular winging. Clinically, a winged scapula can be easily diagnosed by typical physical findings. The cause of this may be: Paralabral ganglion cyst - pressing on the nerve Thickening and/or bony ossification (bony change) of the overlying ligament (Superior Transverse Scapula Ligament - STSL). Dorsal scapular nerve: Origin, course and function | Kenhub A fluoroscopic (x-ray)-guided or ultrasound-guided injection into the area of the nerve at the suprascapular notch may confirm irritation of the nerve if it significantly reduces pain, even temporarily.

Thus, patients with a history of severe COPD are often provided an alternative anesthetic modality. Curr Rev Musculoskelet Med 2008;1:11. Which muscles does the suprascapular nerve innervate? The suprascapular nerve arises from the upper trunk of the brachial plexus which is formed by the union of the ventral rami of the fifth and sixth cervical nerves.After branching from the upper trunk, the nerve passes across the posterior triangle of the neck parallel to the inferior belly of the omohyoid muscle and deep to the trapezius muscle. Learn. Epub 2012 Nov 1. He worked as a cook for 6 years and used his right arm strenuously to cook. Match.

The dorsal scapular artery is a branch of either the transverse cervical artery (from the thyrocervical trunkoff the first part of the subclavian artery)or an independent branch from the third (or less commonly second)part of the subclavian artery. A typical cause is a cyst which occurs as the result of a blow-out of the joint capsule. This creates a potential point of entrapment of the nerve and this can lead to signs and symptoms commonly experienced with DSN injury. The nerve can also be irritated from excessive traction. 1993 Feb; [PubMed PMID: 8439031], Kato K, Innervation of the scapular muscles and its morphological significance in man. The nerve may also be stretch in the case where there is a large rotator cuff tear. From the trunk it passes inferiorly (downwards) under the trapezius muscle towards the superior (top) edge of the scapula, otherwise known as the shoulder blade. Acta Orthop Belg 1990;56:6257. However, the results showed right dorsal scapular neuropathy combined with suprascapular neuropathy. 2006 Sep;22(9):1009-13. The supraspinatus rotator cuff muscle is then retracted away from the nerve and the transverse scapular ligament is then released, while giving caution to preserving both the suprascapular nerve and artery nearby. A direct branch is most likely to pass between the upper and middle trunks of the brachial plexus while an indirect branch is most likely to pass above the upper trunk. We report a case of atypical winged scapula caused by dorsal scapular neuropathy combined with suprascapular neuropathy, which has rarely been reported. The course of the artery also varies as it passes between the trunks of the brachial plexus. Entrapment Neuropathies of the Shoulder | Radiology Key A nerve lesion leads to lateral displacement of the vertebral border of the scapula and to rhomboid atrophy (difficult to detect). This can occur due to winging of the scapula. There were no suspicious signs or symptoms of infection at that time. Wolters Kluwer Health Dorsal Scapular Nerve Entrapment - YouTube Two lower images: After the nerve and vessel are dissected away from the ligament, the transverse scapular ligament (TSL) is then cut, allowing decompression of the suprascapular nerve (SSN) as seen below.

Dorsal scapular nerve entrapment is a very under-recognized cause of neck and shoulder pain. Here, the nerve splits, with one thick branch staying with the supraspinatus and one heading towards the other muscle it supplies, the infraspinatus. Demographic and comorbidity data are shown in Table 1. On needle electromyography, abnormal spontaneous activities were found in the right supraspinatus and infraspinatus muscles. modify the keyword list to augment your search. The dorsal scapular nerve (DSN) is a motor nerve arising from the ventral ramus of the C5 nerve root. Patients usually feel deep pain over the top and back of the shoulder. [1], The dorsal scapular nerve innervates the rhomboid major and minor muscles, which provide scapular retraction, elevation, and medial rotation of the inferior scapular angle. This condition may result from weakness of the muscles which control the scapula or injury to the nerve which makes the scapular muscles work properly. The authors alone are responsible for the content and writing of the article.

Isolated dorsal scapular nerve injury is uncommon, with the mechanism believed to be injury to the scalene muscles (10). This is a common site of the nerve entrapment or compression. 52 year old bodybuilder and weight lifter one year after suprascapular nerve release and partial repair of a massive rotator cuff tear. It then goes underneath the muscles of the rotator cuff to which it gives small nerve branches.. Entrapment of the SPN, classically referred to as Wartenberg syndrome, typically occurs secondary to friction between the mid-forearm muscle bellies and tendons as the nerve exits the deep fascia. EDX can aid in diagnosis of DSN entrapment and hydrodissection may be a reasonable treatment option.
