Thumb Basal Joint (CMC I) Arthritis - Preoperative Anxiety/Depression, Outcome Instruments, Carpal Cinematics and Cost-utility

Thumb Basal Joint (CMC I) Arthritis - Preoperative Anxiety/Depression, Outcome Instruments, Carpal Kinematics and Cost-utility

A project aiming to promote evidence based practice when treating thumb basal joint (CMC I) arthritis. We will aim to: 1) provide the minimal clinical difference of two general outcome instruments, 2) evaluate the association between pre-operative anxiety and/or depression and outcomes following trapeziectomy, 3) evaluate the effect of trapziectomy on carpal cinematics, 4) determine the cost-utility-ratio of trapeziectomy
