Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Decrease of the symptomatology related to the STT OA	Quality of life related to STT OA evaluated using Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire (0 = no disability, 100 = most severe disability); a decrease of 25% of the score is expected between subject's inclusion and the 12-month postoperative visit	12 months
Secondary	Absence of inflammatory reactions and good local tolerance of the implant	No inflammatory reactions (oedema, erythema, necrosis, ulceration and/or delayed wound healing), no adverse effects or serious adverse effects.	Through study completion (12 months)
Secondary	Decrease of pain related to STT OA	Pain evaluated from 0 (no pain) to 10 (worst imaginable pain) on a visual analog scale (VAS)	1 month, 3 months, 6 months, 12 months
Secondary	Improvement of functional activities involving the thumb	Functional activities involving the thumb evaluated from 0 (best) to 56 (worst) using the Buffet score developed by the Besançon University Hospital	1 month, 3 months, 6 months, 12 months
Secondary	Increase of thumb strength	Thumb strength measured in kg by two-point pinch strength test using a pinch gauge	3 months, 6 months, 12 months
Secondary	Increase of grip strength	Grip strength measured in kg by grip strength test using a dynamometer	3 months, 6 months, 12 months
Secondary	No apparent joint space anomaly	Joint space evaluated on radiography using Crosby's classification	12 months
