Introduction Inflammatory arthritis frequently affects the wrist, resulting in pain and disability. This study aims to investigate the long-term outcome of patients who underwent posterior interosseous nerve (PIN) denervation for inflammatory arthritis of the wrist. Method xForty consecutive wrists (36 patients) treated with PIN denervation were identified (mean follow-up 47 months; mean age 62.6 years, 77.5% female). Pain and function scores were objectively measured using the patient-rated wrist-evaluation (PRWE) questionnaires. Data was compared for pre-operation and post-operation (early and long term). The Student’s t test was used to compare differences between groups for continuous data, whilst the sign test was utilised for pairwise comparisons. The p value was set at 0.05 for all comparisons. Results Three patients died during the course of this study from causes unrelated to wrist surgery, resulting in 93% follow-up. PRWE questionnaires demonstrated a significant improvement following PIN denervation (median pain pre-op 42 vs post-op 16 ( p
