Targeted partial arthroscopic trapeziectomy with temporary distraction: a retrospective study with 5-year follow-up.

Targeted partial arthroscopic trapeziectomy with temporary distraction is a minimally invasive treatment for trapeziometacarpal osteoarthritis. We performed a retrospective single centre study from March 2011 to May 2022 and included patients with at least 5 years of follow-up. A failure was defined as a patient requiring a second procedure. Of the 28 patients with at least 5 years of follow-up, 23 were reviewed. Five of the 23 patients underwent revision surgery with a 5-year survival rate of 78%. There was a significant improvement in pain and the Quick Disabilities of the Arm, Shoulder and Hand (Q-DASH) score. There were three postoperative complications, one with complex regional pain syndrome, and two with hyperesthesia in the distribution of the sensory branch of the radial nerve. Targeted partial arthroscopic trapeziectomy with temporary distraction is a feasible temporary solution for early stage trapeziometacarpal joint osteoarthritis. However, there remains a 20% risk of failure. Level of evidence: IV.
