Selective denervation of the wrist for chronic pain: a systematic literature review.

Selective denervation of sensory nerve branches to the wrist is a palliative surgical treatment option for patients with chronic wrist pain when preserving the range of motion and function is preferred. Treatment varies from partial isolated denervation of the posterior interosseous nerve to extensive 'complete' denervations. This study aimed to provide an overview of the literature regarding treatment outcomes in the domains of pain, grip strength, patient satisfaction and return to work. MEDLINE (PubMed), EMBASE and Cochrane databases were systematically searched and identified 993 studies, of which 12 were eligible for analysis. Denervation resulted in high 'return to work' rates (up to 94%), patient satisfaction (up to 92%), increased grip strength (7%-64%) and improved average pain scores (36%-92%). Treatment outcomes of both partial and complete denervations were favourable; however, variations in outcomes suggest the need for improving evidence regarding surgical technique and nerve identification.
