Scapular nerve entrapment

Compression of the scapular nerve is one of the most common causes of shoulder pain. Some scholars abroad believe that the eigens account for 1% to 2% of all patients with shoulder pain. In 1909, Ewald described a posttraumatic suprascapular neuritis. In 1926, Foster reported 16 cases of suprascapular neuropathy. In 1948, 4 of the 136 shoulder pain cases reported by Parsonage and Turner had suprascapular neuritis. These are the earliest reports of scapular nerve entrapment. In 1959, Kopell and Thompson gave a detailed description of the compression of the scapular nerve on the notch of the scapula, and called it suprascapular nerve entrapment (SNE). In the future, reports on the scapular nerve entrapment gradually increased. In 1982, Aiello et al reported a case of SNE entrapment at the glenoid notch on the scapula. In 1987, Ferretti and others reported cases of SNE in volleyball players. In recent years, there have been reports of atrophy of the subscapular muscle and some special cases of entrapment.
