ScaphoTrapezioTrapezoid OsteoArthritis (STT OA)
Brief summary
The aim of this open, prospective, multicenter trial is to evaluate the use of a sterile, devitalized, processed umbilical cord amniotic membrane implant placed in joint interposition in the treatment of STT osteoarthritis.
Interventions
Decellularized, viro-inactivated, freeze-dried and sterile allogeneic graft of amniotic membrane of umbilical cord used as an interposition implant in the STT joint

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Decrease of the symptomatology related to the STT OA | 12 months | 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 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Decrease of pain related to STT OA | 1 month, 3 months, 6 months, 12 months | Pain evaluated from 0 (no pain) to 10 (worst imaginable pain) on a visual analog scale (VAS) |
| Improvement of functional activities involving the thumb | 1 month, 3 months, 6 months, 12 months | Functional activities involving the thumb evaluated from 0 (best) to 56 (worst) using the Buffet score developed by the Besançon University Hospital |
| Absence of inflammatory reactions and good local tolerance of the implant | Through study completion (12 months) | No inflammatory reactions (oedema, erythema, necrosis, ulceration and/or delayed wound healing), no adverse effects or serious adverse effects. |
| Increase of grip strength | 3 months, 6 months, 12 months | Grip strength measured in kg by grip strength test using a dynamometer |
| No apparent joint space anomaly | 12 months | Joint space evaluated on radiography using Crosby's classification |
| Increase of thumb strength | 3 months, 6 months, 12 months | Thumb strength measured in kg by two-point pinch strength test using a pinch gauge |
