BACKGROUND: This retrospective study examines long-term follow-up results after complete denervation of the wrist. PATIENTS AND METHODS: Between 1994 and 2000 a total of 61 complete wrist denervations of 59 patients (median age at operation 46 years) were performed. In 2009 29 patients with 30 complete wrist denervations took part in a follow-up examination after an average of 10 years. The mobility of the wrist and the grip force were examined. Pain and satisfaction with the operation were determined by means of a visual analogue scale (VAS) (0-100). The patients were asked about pain reduction and how long it lasted. Further the DASH and the Mayo Wrist Score were evaluated. Radiographs of the denervated wrist were performed and the degree of the degenerative osteoarthritis was determined according to Knirk and Jupiter. RESULTS: In 7 of the 36 patients examined, a partial or total wrist arthrodesis was performed. These patients were excluded from the study. Pain was improved in 28 of the 30 denervated wrists examined, in 22 the improvement lasted until the follow-up examination, whereas in 6 the pain increased after a median of 90 months. The median pain intensity was 10 at rest and 50 with activity; the satisfaction was 90. The median of the extension/flexion was 81% and the grip force 82% in comparison to the opposite hand. The DASH Score was 25 and the Mayo Wrist Score 73. CONCLUSION: Complete denervation of the wrist according to Wilhelm is a treatment option for the chronically painful wrist and can lead to good grip force, mobility, sufficient pain reduction and satisfaction in the long term.
