Eхperience of endoscopic decompression of the suprascapular nerve

Abstract

Relevance. Suprascapular nerve neuropathy is a commonly spread pathology, caused by traction force trauma or compression in scapular notch area. In case of failure of conservative treatment standard surgical procedure is neurolysis (decompression) of suprascapular nerve in scapular notch. This procedure can be done open or endoscopically.
 Goal. Evaluate the results of endoscopic decompression of suprascapular nerve in scapular notch area.
 Material and methods. We operated 10 patients for the period from 2015 to 2021 year with the clinical situation of posttraumatic suprascapular nerve neuropathy. The mean age of patients was 52,311.8. To all the patients was performed shoulder joint and subacromial space arthroscopy, decompression of suprascapular nerve in scapular notch area. Statistics was made according to Mann-Whitney U-test.
 Results. According to VAS-scale the severity of pain syndrome before the surgery was 61,5 cm., 6 months after the surgery decreased to 2 0.5 cm (p0.05). According to DASH scale the dysfunction of the of shoulder joint before the surgery was 70,2 5,8 points, 6 months after the surgery decreased to 10 4,8 points (p0.05). Range of motion in a shoulder joint before the surgery was: flexion 155 14,4, abduction 140 42, external rotation 12 5,6; 6 months after the surgery: flexion 174 15,6, abduction 175 14,4, external rotation 48 9.
 Conclusion. The results do let us characterize the method of endoscopic decompression of suprascapular nerve as a low-traumatic and effective technique, which promotes restoration of function of suprascapular nerve and shoulder joint, elimination of pain syndrome from shoulder area.
