“…Furthermore, it is easy to measure these two diameters on a plain radiograph. The projection in which the SSN is visualized clearly is the anteroposterior projection with the X-ray tube angled 15-308 caudally (Edeland and Zachrisson, 1975). In addition, because of its simple character, our method is easy to remember and use.…”

“…Kopell and Thompson (1959) originally described SN entrapment syndrome at the SSN. Many causes and conditions have since been correlated with neuropathy of the SN, such as fractures of the scapula (Edeland and Zachrisson, 1975;Solheim and Roaas, 1978;Antoniadis et al, 1996), blunt trauma to the shoulder region (Rengachary et al, 1979b;Antoniadis et al, 1996), anterior glenohumeral dislocation (Zoltan, 1979), ganglion cysts (Antoniadis et al, 1996;Rochwerger et al, 1996), lipomas (Hazrati et al, 2003), and other tumors (Fritz et al, 1992). There have also been reports of anomalous passage of the suprascapular artery through the SSN (Tubbs et al, 2003), a hypertrophied subscapularis muscle covering the anterior surface of the SSN (Bayramoglu et al, 2002), angular changes of the superior transverse scapular ligament (STSL) due to the attachment of the omohyoid muscle to the ligament (Bayramoglu et al, 2003), and increased tension on the SN due to retraction of the rotator cuff after a massive tear (Albritton et al, 2003).…”

The present study proposes a simple and reproducible method to classify the morphology of the suprascapular notch (SSN), on the basis of specific geometrical parameters that clearly distinguish one type from another. Four hundred twenty-three dried scapulas from the Department of Anatomy in the University of Cologne, Germany, were examined. Five types of SSN were observed: type I, without a discrete notch, 35 (8.3%); type II, a notch that was longest in its transverse diameter, 177 (41.85%); type III, a notch that was longest in its vertical diameter, 177 (41.85%); type IV, a bony foramen, 31 (7.3%); type V, a notch and a bony foramen, 3 (0.7%). For the vertical diameter, we took the maximal diameter of the notch perpendicular to the imaginary line that joins the two superior corners of the notch. For the transverse diameter, we took the diameter perpendicular to the midpoint of the vertical diameter. This classification based on the vertical and the transverse diameters of the SSN suggested a clear distinction of the notch types. This simple classification included all the anatomical variations of the SSN. Using this method, the clinician will be able to define easily and quickly the notch type on a plain radiograph, and perhaps be able to correlate suprascapular nerve entrapment with a specific type of SSN.

“…This nerve may be acutely damaged as a result of trauma, with or without fracture of the shoulder. 10,39 It is less often damaged by stretching due to forced forward rotation of the scapula around the chest wall, or it may be chronically compressed by a bone callous, gangliar or synovial cyst, and hypertrophy of the upper or lower transverse scapular ligaments. In the latter case, only the infraspinatus muscle is affected.…”

“…[1,2] It may occur trauma, repetitive overhead activities, or in the setting of a massive rotator cuff tear due to a traction injury. [3–6] Another reason for injury of the nerve can be compression from a mass lesion such as a paralabral ganglion cyst. Other masses such as synovial sarcoma, Ewing sarcoma, and chondrosarcoma have been reported.…”

Rationale:Suprascapular nerve compression is a rare but important entity that is often missed in clinical practice. Nerve dysfunction caused by an intraosseous ganglion of the glenoid is extremely rare, to the best of our knowledge, only 1 case of suprascapular nerve entrapment due to an intraosseous ganglion cyst has been reported previously in the published literature.Patient concerns:We report a 61-year-old woman who had complained right shoulder pain that lasted over 3 years which was exacerbated by overhead activities.Diagnoses:We diagnosed it as suprascapular nerve entrapment at the spinoglenoid notch caused by an intraosseous ganglion of the scapula.Interventions:Plain X-ray, computed tomography, magnetic resonance imaging (MRI), and electromyography (EMG) of the shoulder.Outcomes:She undertook surgical excision with curettage of the cyst. The infraspinatus fossa dull pain subsided immediately after surgery. No recurrence of the cystic lesion was noted on follow-up plain radiograph and MRI performed 18 months postoperatively. Shoulder external rotation strength was graded as 5 of 5.Lessions:Intraosseous ganglion of the glenoid can cause compression of the suprascapular nerve when the lesion is expanded toward the spinoglenoid notch. The EMG study confirmed compression of the suprascapular nerve. The patient showed clinical and radiologic improvement after surgical decompression with no recurrence.
