“…[2][3][4][5][6] In a patient with SSN palsy caused by entrapment of the SSN at the suprascapular notch, pain and sensory disturbance in the upper lateral shoulder improved after an open release of the SSN, suggesting the presence of a cutaneous branch of the SSN. 4 In 7 patients with SSN palsy, 6 had sensory disturbance and heat sensation at the posterior aspect of the shoulder and axilla, which improved after puncture of the ganglion and further surgery.…”

Purpose. To determine the association of the area of sensory disturbance with the area of suprascapular nerve (SSN) palsy in healthy volunteers and patients with SSN palsy. Methods. Five male and one female and healthy volunteers aged 23 to 44 (mean age, 32.2) years underwent an experiment of distal and proximal SSN block (at the spinoglenoid notch and suprascapular notch, respectively). A pinprick test was performed to determine pain sensation and the area of sensory disturbance. In addition, records of 21 male and 19 female patients aged 21 to 75 (mean, 54.1) years who underwent arthroscopic SSN release for SSN palsy were reviewed. The same pinprick test was performed. Results. After distal SSN block, 5 volunteers had a sensory deficit in the area below the scapular spine only, and one had no sensory deficit. After proximal SSN block, the sensory deficit spread to both lateral and medial sides above and below the scapular

“…They found complete nerve recovery in four out of six patients. Oizumi et al [17] performed an arthroscopic release in 18 patients with a rotator cuff tear and all had complete recovery from SSN palsy, although the diagnosis was clinical and no NC/EMG studies were done. Lafosse et al [1] mention unpublished data of 29 massive rotator cuff tear cases accompanied by SSN neuropathy, where no statistical difference was found between patients who underwent nerve release and patients who did not; however, no further data or tables are provided and the cases are anecdotal.…”

BackgroundIt 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/designThis 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. Nerve function will be measured by nerve conduction and electromyography studies preoperatively and at the selected follow-up periods. Patients will be randomly divided into equally numbered groups, the first one being the control group. Patients of this group will undergo arthroscopic repair of the rotator cuff without combined arthroscopic release of the superior transverse scapular ligament; in the second group the ligament will be released. The primary objective is to test the null hypothesis that arthroscopic repair of large/massive rotator cuff tears in patients with combined suprascapular neuropathy provides equivalent outcomes to one-stage arthroscopic cuff repair where the superior suprascapular ligament is additionally released. The secondary objective is to search for a relation between rotator cuff tear size and degree of suprascapular nerve recovery. The tertiary objective is to demonstrate any relation between rotator cuff muscle fatty infiltration grade and degree of suprascapular nerve function. Patients, clinicians during follow-up clinics and the neurologist will be blinded to the type of surgery performed.DiscussionTo the best of our knowledge, we are unaware of any prospective, randomized double-blinded studies with similar objectives. So far, the evidence suggests a positive correlation between massive rotator cuff tears and suprascapular neuropathy. However, there is mixed evidence suggesting that neuropathy can be effectively treated with rotator cuff repair with or without release of the superior transverse scapular ligament.Trial registrationClinicalTrials.gov registration number NCT02318381; date of initial release: 5 December 2014.Electronic supplementary materialThe online version of this article (doi:10.1186/s13063-016-1672-y) contains supplementary material, which is available to authorized users.

“…Its sensory territory, which varies widely, is located at the posterior and superior aspect of the shoulder over the glenohumeral joint space [14]. In addition, a posterior capsular branch contributes to sensation from the glenohumeral joint, particularly its proprioception.…”

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. The potential relevance of concomitant rotator-cuff tears remains debated. Less common causes include tumours, scapular fractures, and direct trauma involving traction. Early diagnosis and treatment are crucial to avoid the development of irreversible muscle wasting. Endoscopic surgery to treat the various causes of suprascapular nerve compression has superseded open nerve release.
