Overview

Ultrasound-guided perineural injection (PIT) of 5% dextrose (D5W) hydrodissection has been widely used in the treatment of peripheral entrapment neuropathies. However, there are few studies investigating the efficacy of PIT using D5W HD for dorsal scapular nerve (DSN) entrapment. Generally, the DSN entrapment causes the stiffness of the major and minor rhomboideus(2). In clinical practice, the investigators observed that ultrasound-guided PIT using D5W HD combined with needle release of major and minor rhomboideus significantly relieved the pain of scapular region. Therefore, the investigators aimed to evaluate the 6-month efficacy of this procedure for the participants with DSN entrapment.

Outcomes

Primary Outcomes

visual analogue scale (VAS)

VAS is the most common tool to evaluate discomfort for patients with peripheral entrapment neuropathies, with scores ranging from 0 (no pain) to 10 (intolerant pain)

Time frame: before treatment, as well as 1, 3, 6 months post treatment
