Résultats fonctionnels et qualité de vie après révision décompression du canal carpien

This study describes functional outcomes, patient satisfaction, and health-related quality of life (HRQoL) following open revision carpal tunnel decompression (CTD) for recurrent carpal tunnel syndrome (CTS). Postoperative results were available for 16 hands in 15 patients (100% at mean follow-up at 19.9 months). This was a prospective study at a single-centre serving a population of 360,000. QuickDASH, patient satisfaction, and EQ-5D-5L questionnaires were collected pre and postoperatively for patients undergoing revision CTD over a five-year period (2013–2018). The incidence of revision CTD was 0.9 per 100,000 patients per year. Fifteen patients reported recurrent and 1 patient-reported persistent symptoms. Median time to revision was 12.5 years (interquartile range 6.7–15.7 years). Mean preoperative and postoperative quickDASH was 57.7 and 36.1, respectively. The overall mean improvement in QuickDASH was 28.1. The mean improvement in EQ-5D-5L was 0.17. Thirteen patients (81.8%) were satisfied. The Net Promoter Score was 87.5. This study confirms the widely-held view that patients with late-presenting CTS can expect to enjoy a similar improvement in function and HRQoL as patients undergoing primary CTD. Recurrent CTS presents following a long symptom-free period after primary CTD, and hand function regresses to a similar level of disability. These results can be used to counsel patients who are considering revision surgery.
