BACKGROUND: It has been indicated that rotator cuff tears, especially large or massive ones, can cause suprascapular neuropathy. When such a diagnosis has been established, it is still unknown whether an arthroscopic release of the superior transverse scapular ligament during cuff repair can change the course of this neuropathy. METHODS/DESIGN: This is a single-center, double-blinded randomized controlled trial for which 42 patients with large or massive repairable rotator cuff tears and suprascapular neuropathy will be recruited and followed up at 6 and 12 months...

BACKGROUND: When closed by the superior transverse scapular ligament (STSL), the suprascapular notch (SSN) creates an osseo-fibrous tunnel which acts as a pathway for the suprascapular nerve (SN). Anatomical variations are common in this region, and these can increase the risk of neuropathy by restricting the space for nerve passage. The aim of this study is to identify any correlation between the area reduction coefficient parameters and the SN and vessel arrangements in the SSN region...

AIMS: Our aim was to describe the atypical pattern of increased fatty degeneration in the infraspinatus muscle compared with the supraspinatus in patients with a massive rotator cuff tear. We also wished to describe the nerve conduction and electromyography findings in these patients. PATIENTS AND METHODS: A cohort of patients undergoing surgery for a massive rotator cuff tear was identified and their clinical records obtained. Their MRI images were reviewed to ascertain the degree of retraction of the torn infraspinatus and supraspinatus muscles, and the degree of fatty degeneration in both muscles was recorded...

The spectrum of clinical and electrophysiological features in hereditary neuropathy with liability to pressure palsies (HNPP) is broad. We analyze a series of Brazilian patients with HNPP. Correlations between clinical manifestations, laboratory features, electrophysiological analyze, histological and molecular findings were done. In five cases, more than one episode occurred before diagnosis. Median nerve in the carpal tunnel at the wrist, ulnar nerve in its groove at the elbow, fibular nerve in the head of the fibula at the knee, radial nerve in its groove of the humerus and suprascapular nerve in its notch at the supraspinous fossa were found as focal neuropathies...

Supra-scapular nerve (SSN) damage is a rare, but classical diagnosis that can often be overlooked since the nonspecific clinical history and examination commonly lead to the misdiagnosis of another shoulder disorder. This article details the etiopathology, the patients at risk, the reasons for consultation and the clinical aspects of suprascapular neuropathy; it also outlines its diagnostic and therapeutic approaches.

Type 2 superior labral anterior to posterior (SLAP) lesion is a common cause of shoulder pain requiring surgical operation. SLAP tears are often associated with paralabral cysts, but they rarely cause nerve compression. However, we experienced two cases of type 2 SLAP-related paralabral cysts at the spinoglenoid notch which were confirmed as isolated nerve entrapment of the infraspinatus branch of the suprascapular nerve by electrodiagnostic assessment and magnetic resonance imaging. In these pathological conditions, comprehensive electrodiagnostic evaluation is warranted for confirmation of neuropathy, while surgical decompression of the paralabral cyst combined with SLAP repair is recommended...

BACKGROUND: The suprascapular notch is a clinically important site because it is the main site of injury and compression of the suprascapular nerve. Its shape and size are the most important factors in the aetiopathology of suprascapular nerve neuropathy. This article reports the first computed topography (CT) study on the correlation between the diameters of the suprascapular notch and anthropometric measurements of the human scapula. MATERIALS AND METHODS: A total of 130 scans of shoulders by a helical 32-row multidetector CT scanner were retrospectively analysed...

Rotator cuff (RC) disease is an extremely common condition associated with shoulder pain, reduced functional capacities, and impaired quality of life. It primarily involves alterations in tendon health and mechanical properties that can ultimately lead to tendon failure. RC tendon tears induce progressive muscle changes that have a negative impact on surgical reparability of the RC tendons and clinical outcomes. At the same time, a significant base of clinical data suggests a relatively weak relationship between RC integrity and clinical presentation, emphasizing the multifactorial aspects of RC disease...

BACKGROUND: The suprascapular notch (SSN) is the most common site of suprascapular nerve neuropathy, which may be brought on by the presence of a deep, narrow SSN and structures restricting the space for the nerve. The anterior coracoscapular ligament (ACSL) is a fibrous band extending on the anterior side of the suprascapular notch. As it may tighten the osteo-fibrous tunnel for the nerve, it has been proposed as a new anatomical risk factor in its entrapment. However, this structure occurs in up to 60% of patients, many of whom do not demonstrate any nerve injury...

UNLABELLED: Subclavius posticus is a rare anomalous muscle that traverses from the costal cartilage of the first rib posterolaterally to the superior border of the scapula. We present an athlete who presented with incapacitating suprascapular nerve compression associated with a subclavius posticus diagnosed by MRI. Symptoms were relieved, and function was restored by decompression of the nerve and excision of the anomalous muscle. We present this case to bring awareness of the subclavius posticus as an anatomic variant and a potential additional source for compression in suprascapular neuropathy...

OBJECTIVE. In this article, we will review the normal anatomy and imaging features of various neuromuscular abnormalities related to suprascapular neuropathy. CONCLUSION. Suprascapular neuropathy can be difficult to distinguish from rotator cuff pathology, plexopathy, and radiculopathy. Electrodiagnostic studies are considered the reference standard for diagnosis; however, high-resolution 3-T MR neurography (MRN) can play an important role. MRN enables direct visualization of the nerve and simultaneous assessment of the cervical spine, brachial plexus, and rotator cuff...

STUDY DESIGN: Resident's case problem. BACKGROUND: Acromioclavicular joint pathology is reported to be present in up to 30% of all patients complaining of shoulder dysfunction. The operative approach to treating acromioclavicular joint disease often includes a distal clavicle excision and, in circumstances of acromioclavicular joint instability, reconstruction of the coracoclavicular and/or the acromioclavicular ligament. Surgical complications for these procedures are rare, but potentially include suprascapular neuropathy secondary to the course of the suprascapular nerve posterior to the clavicle prior to entering the supraspinatus fossa...

Focal neuropathies represent a rare but clinically important and potentially challenging aetiology of pain in athletes. Diagnostic ultrasound is commonly used in the evaluation of nerve entrapments, and has several advantages over other imaging modalities, including high resolution, portability, lack of ionising radiation, low cost, point-of-care access, ease of contralateral comparison and capability of Doppler and dynamic imaging techniques. In this review, we discuss the use of ultrasound for the evaluation of injuries to the brachial plexus including 'stingers,' suprascapular nerve, ulnar nerve, radial nerve, common fibular nerve, tibial nerve and interdigital nerves of the foot at selected common sites of entrapment...

Suprascapular nerve entrapment was first described in 1959 by Kopell and Thompson. Although rare, this condition is among the causes of poorly explained shoulder pain in patients with manifestations suggesting a rotator-cuff tear but normal tendons by imaging studies. Suprascapular nerve entrapment may cause 2% of all cases of chronic shoulder pain. Among the many reported causes of suprascapular nerve entrapment, the most common are para-labral cysts, usually in the spinoglenoid notch, and microtrauma in elite athletes...

BACKGROUND: The suprascapular notch (SSN), bridged by the superior transverse scapular ligament (STSL), creates a pathway for the suprascapular nerve (SN). Morphological variations in the SSN region are common and can increase the risk of neuropathy by constricting the space for the nerve. The aim of this study was to establish new objective parameters that take this complex morphology into account. METHODS: The SSN region of 100 formalin-fixed cadaveric shoulders was dissected...

BACKGROUND: Pain in the shoulder is a common problem in overhead sports and at times goes along with atrophy of the supra- and infraspinatus muscles. A neuropathy of the suprascapular nerve is one possible reason. The aim of the study was to examine the suprascapular nerve in Austrian high-performance beach volleyball players. METHODS: In this cross-sectional study, 18 high-performance beach volleyball players were included. An electrophysiological examination was performed consecutively...
