Trapeziumectomy And Mini Tightrope Stabilization Of The First Metacarpal For Thumb Carpometacarpal Osteoarthritis : A Prospective Case Series.

Our purpose was to investigate the short-term results of trapeziumectomy and stabilization of the first metacarpal by using the TightRope© device, at a maximum follow-up of 1 year post-op. This is a novel method in treating first carpometacarpal joint osteoarthritis and an alternative to the variety of other methods that have been previously reported. We recruited 21 patients and assessed them at regular intervals, comparing pre-operative and postoperative variables. We recorded all complications during the study period. There was a statistically significant improvement in pain, hand grip and tip pinch power and functional outcome scores. Patients were very satisfied at 12 months after surgery. No significant change in thumb opposition was noted. There was subsidence of the first metacarpal at 1 year after surgery. Despite the existence of a significant number of alternative procedures, we feel that the procedure described in this paper has promising short-term results and is safe.
