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

RECRUITINGPatient-Rated Wrist Evaluation
The PRWE comprises 15 questions to measure wrist pain and disability in daily activities. In PRWE patients rate wrist pain and disability from 0 to 10 and it consists two subscales: Pain and Function (0=best possible outcome, 10=worst possible outcome)
Time frame: 12 months
Michigan Hand Outcome Questionnaire
A hand-specific outcomes instrument that contains six distinct scales: (1) overall hand function, (2) activities of daily living, (3) pain, (4) work performance, (5) aesthetics, and (6) patient satisfaction with hand function.
Time frame: 12 months
Pain Catastrophizing Scale
A pain catastrophizing scale comprising of three subscales: (1) Helplessness, (2) Rumination, and (3) Magnification
Time frame: 12 months
Pain (Visual Analogue Scale)
The VAS is derived by health care professional question of pain in scale 0 to 10 (0=no pain, 10=worst possible pain)
Time frame: 12 months
Global improvemen
Global rating to treatment effect will be evaluated by question: "How would you rate the function of your hand compared to the situation before the treatment?". The options are in 5-step Likert scale from (-2) Much worse to (+2) Much better
Time frame: 12 months
Grip strength
Grip strength is measured with a dynamometer in kg as the mean of three measurements. It will be numbered in kg and percentage of the unaffected side
Time frame: 12 months
Wrist and hand (thumb) range of motion (ROM)
ROM is measured on both hands with a handheld goniometer in degrees.
Time frame: 12 months
Cost-utility
Quality-adjusted life years/months measured as a change in EQ-5D
Time frame: 12 months
Carpal Kinematics
Evaluated from preoperative and compared to 1-year postoperative 4-dimension cone-beam tomography - the wrists are imaged in 7 different postures to reproduce carpal movement, the pre and postoperative scans will be compared to evalueate the effect of trapeziectomy on carpal kinematics (e.g. scapholunate angle, lunotriquetral angle, metacarpal subsidence)
Time frame: 12 months
Beck Depression Inventory
21-item, self-report rating inventory that measures characteristic attitudes and symptoms of depression
Time frame: 12 months
