BACKGROUND: Advanced proximal carpal row damage is common in rheumatoid arthritis (RA). Proximal row carpectomy (PRC) simplifies total wrist arthrodesis, obviating the need for an iliac bone graft. In theory, PRC also improves the chances of healing, as fusion of a single joint space is needed for the procedure to be successful. Potential effects of the loss of carpal height related to PRC are unknown. HYPOTHESIS: We hypothesised that PRC performed concomitantly with total wrist arthrodesis in patients with RA produces good clinical and radiological outcomes, without inducing loss of strength or digital deformities. MATERIAL AND METHODS: In 38 total arthrodeses of rheumatoid wrists, a clinical evaluation was performed, including a visual analogue scale (VAS) pain score, the Patient-Rated Wrist Evaluation (PRWE), grip strength, digital deformities, and patient satisfaction. A standard radiographic workup was obtained to assess healing and carpal height indices. RESULTS: After a mean follow-up of 50 months, the mean VAS pain score was 0.4 (range: 0-7), the mean PRWE score was 21 (range: 0-80.5), and grip strength as a percentage of the contralateral limb was 76%. The healing rate was 92% (35/38 wrists), and 34 (90%) patients reported being satisfied or very satisfied. No effects of carpal height loss on clinical or radiographic parameters was detected. DISCUSSION: Total wrist arthrodesis combined with PRC provides reliable and reproducible benefits. This study found no evidence of adverse effects related to the loss of carpal height. LEVEL OF EVIDENCE: IV, retrospective study.
