Abstract: Background: Trapeziectomy with ligament reconstruction and tendon interposition (LRTI) with the flexor carpi radialis (FCR) tendon is one of the most common procedures for the treatment of trapeziometacarpal osteoarthritis. We modified the LRTI, using the palmaris longus (PL) tendon instead of the FCR tendon. The aim of this retrospective study was to evaluate the clinical outcomes of trapeziectomy with our modified LRTI procedure at a mean follow-up of 5 years. Methods: Fourteen thumbs in 13 patients (12 women) with a mean age of 64 years (range, 50 to 77 years) were available for assessment for a mean duration of 62 months (range, 41 to 97 months). The patients were evaluated subjectively and objectively. Results: The modified LRTI procedure provided good pain relief, motion, strength, and stability without any severe complications related to the PL tendon harvesting. Radiography showed that compared to the preoperative status, the trapezial space decreased by about 40% at the final follow- up. Conclusions: The modified LRTI procedure provided significant subjective and objective improvements without severe complications particularly related to the harvesting of the PL tendon. This procedure is a valuable surgical option for trapeziometacarpal osteoarthritis and could be a useful salvage modality if the FCR tendon ruptures during the conventional LRTI procedure.
