Abstract
INTRODUCTION Recent studies demonstrated the utility of perineural injection with platelet-rich plasma (PRP) and 5% dextrose (D5W) as novel strategies for treatment of carpal tunnel syndrome (CTS). The present study comprised a prospective, randomized, single-blind, head-to head comparative trial to compare the six-month outcome of perineural injection with PRP or D5W in patients with moderate CTS. METHODS Fifty-two patients with unilateral moderate CTS were enrolled and randomized into two groups: the PRP group received a single 3-cc perineural injection of PRP under ultrasound guidance and dextrose group received a single 3-cc perineural injection of D5W under ultrasound guidance. The Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) score was used as the primary outcome. Secondary outcomes included cross-sectional area (CSA) of the median nerve and electrophysiological assessments. Evaluations were performed at baseline and at 1, 3, and 6 months post-injection. RESULTS All patients (26 patients per group) completed the study. Compared with the dextrose group, the PRP group demonstrated significant reductions in BCTQ-function at 3 months (p = 0.044), distal motor latency at 6 months (p = 0.028), and CSA at 3 and 6 months (p = 0.010 and 0.018, respectively). CONCLUSIONS A single perineural injection of PRP reduced the CSA of the median nerve more effectively than injection of D5W at 3 and 6 months post-injection for patients with moderate CTS.
