Patient satisfaction and outcomes of partial wrist denervation in inflammatory arthritis.

This study highlights the effectiveness of PIN denervation as a simple alternative to wrist arthrodesis due to long-term improvement in pain and preservation of function. We recommend this procedure in the presence of a positive diagnostic PIN infiltration test to avoid wrist arthrodesis for as long as possible. In patients with predominantly ulnar-based wrist pain, the outcome is less predictable and this subgroup of patients should be counselled about the possibility of subsequent salvage wrist fusion. Key Points • One of the largest study cohorts which report on the outcome of the wrist PIN denervation procedure with over 2-year follow-up • Clinical outcomes of success are enhanced with the use of validated, objective patient-reported outcome measures relating to overall satisfaction, pain relief and function. • Long-term outcomes are compared to pre-operative and immediate post-operative outcome scores, demonstrating the benefits of PIN denervation and the longevity it provides.
