Partial wrist denervation versus total wrist denervation: A systematic review of the literature

The aim of this systematic review was to understand which procedure-total or partial wrist denervation-provides better results in terms of pain relief and function. This review was registered on PROSPERO (CRD42018088856). We searched the Medline (PubMed), Web of Science and Scopus databases. Twenty-one studies were included in this review. We assessed the quality of the studies using the Coleman Methodological Score. Data on demographics, surgical indications, diagnostic methods, follow-up periods, type and rates of complications, survivorship of the procedure, return to work, and outcome measures were recorded. A total of 1065 patients were included in this review; the mean quality of the studies included was considered poor. The outcomes could not be analyzed because none of the studies had reliable outcome data reported, but both procedures were effective in terms of pain relief and range of motion. Partial wrist denervation has an average subsequent procedure rate of 19%. Total wrist denervation had an average subsequent procedure rate of 4.7%. No complications were reported in any patient who underwent partial wrist denervation versus 20 patients who underwent total wrist denervation. Both partial and total wrist denervation are safe and reliable procedures that can provide good pain relief and preserve wrist range of motion. Total wrist denervation offers better long-term outcomes in term of pain relief, with fewer subsequent procedures being needed compared to partial denervation, and with a low complication rate.
