The extremes of shoulder mobility required for competitive overhead athletes, particularly in the position of abduction and external rotation, place this cohort at particular risk. Anatomically, the suprascapular nerve is most prone to entrapment at the level of the suprascapular or spinoglenoid notch; the axillary nerve is most prone to entrapment as it traverses the confines of the quadrilateral space.<\/jats:p><jats:p>Radiographs should be ordered as a primary imaging study to evaluate for obvious pathology occurring along the course of the nerves or for pathology predisposing the patient to nerve injury. Magnetic resonance imaging plays a role in not only identifying any mass-compressing lesion along the course of the nerve, but also in identifying muscle signal changes typical for denervation and\/or fatty atrophy in the distribution of the involved nerve.<\/jats:p>","DOI":"10.1055\/s-0042-1742752","type":"journal-article","created":{"date-parts":[[2022,5,24]],"date-time":"2022-05-24T22:33:05Z","timestamp":1653431585000},"page":"114-122","source":"Crossref","is-referenced-by-count":2,"title":["Entrapment Neuropathies of the Shoulder"],"prefix":"10.1055","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7306-3374","authenticated-orcid":false,"given":"Erin F.","family":"Alaia","sequence":"additional","affiliation":[{"name":"Musculoskeletal Division, Department of Radiology, NYU Langone Health, New York, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael S.","family":"Day","sequence":"additional","affiliation":[{"name":"WellSpan Orthopedic Group, Chambersburg, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael J.","family":"Alaia","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, NYU Langone Orthopedic Hospital\/NYU Langone Health, New York, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2022,5,24]]},"reference":[{"issue":"01","key":"ref1","doi-asserted-by":"crossref","first-page":"72","DOI":"10.1007\/s00167-003-0443-y","article-title":"Compression of the suprascapular nerve by a ganglion cyst of the spinoglenoid notch: the arthroscopic solution","volume":"12","author":"S Lichtenberg","year":"2004","journal-title":"Knee Surg Sports Traumatol Arthrosc"},{"issue":"02","key":"ref2","doi-asserted-by":"crossref","first-page":"e13","DOI":"10.1016\/j.jse.2010.09.004","article-title":"The suprascapular nerve and its articular branch to the acromioclavicular joint: an anatomic study","volume":"20","author":"N A Ebraheim","year":"2011","journal-title":"J Shoulder Elbow Surg"},{"issue":"03","key":"ref3","doi-asserted-by":"crossref","first-page":"500","DOI":"10.1016\/j.jse.2007.10.008","article-title":"The sensory branch distribution of the suprascapular nerve: an anatomic study","volume":"17","author":"W Vorster","year":"2008","journal-title":"J Shoulder Elbow Surg"},{"issue":"11","key":"ref4","doi-asserted-by":"crossref","first-page":"665","DOI":"10.5435\/00124635-200911000-00001","article-title":"Suprascapular neuropathy","volume":"17","author":"D P Piasecki","year":"2009","journal-title":"J Am Acad Orthop Surg"},{"key":"ref5","volume-title":"Gray's Anatomy E-Book: The Anatomical Basis of Clinical Practice. 41st ed","author":"S Standring","year":"2016"},{"issue":"223","key":"ref6","first-page":"126","article-title":"Suprascapular nerve entrapment.
