Retrospective case series reporting long-term functional and patient-reported outcomes of trapeziectomy with palmaris longus interposition combined with dynamic transfer of the APB and opponens pollicis origins to the FCR tendon for Eaton stage 3–4 thumb CMC osteoarthritis, with average 9-year follow-up in 22 patients.
When counseling patients on basal joint arthroplasty options, this technique — APB and opponens transfer to FCR plus tendon interposition.
Offers a dynamic stabilization alternative to standard LRTI that achieves equivalent grip recovery and high satisfaction at nearly a decade of follow-up, without formal ligament reconstruction or bone tunnels.
The one caveat: revision cases (e.g., after failed silastic implant) carry higher residual instability risk and warrant specific informed consent.
