Prospective RCT of 153 thumbs randomized to simple trapeziectomy, trapeziectomy with palmaris longus interposition, or trapeziectomy with FCR ligament reconstruction and tendon interposition (LRTI), asking whether the added soft tissue procedures improve outcomes over trapezial excision alone at a minimum of 5 years (median 6 years, range 5–18 years).
