Trapeziectomy with or without a tendon-based adjunct: a registry-based study of 650 thumbs

Abstract

This study aimed to assess the outcomes after simple trapeziectomy and trapeziectomy with ligament reconstruction and/or tendon interposition based on data in the Swedish national healthcare quality registry for hand surgery (HAKIR). Six-hundred and fifty thumbs were included, and 265 were assessed up to 12 months after operation. There was significant and clinically relevant improvement in patient-reported measures (pain on load, pain on motion without load, pain at rest, stiffness, weakness, and ability to perform activities of daily living and the Quick Disabilities of the Arm, Shoulder and Hand score) and objective measures (strength and thumb mobility) at 3 and 12 months for all procedures. The use of the abductor pollicis longus tendon had better improvement in some respects compared with the use of flexor carpi radialis or extensor carpi radialis tendons. However, overall, the use of a tendon adjuncts yielded no better outcomes than simple trapeziectomy. Level of evidence: III.
