Use of a Treated, Devitalized and Sterile Umbilical Cord Amniotic Membrane in the Treatment of STT Osteoarthritis

Evaluation of the Treatment of Symptomatic Scaphotrapeziotrapezoidal (STT) Osteoarthritis With a Treated, Devitalized and Sterile Amniotic Membrane of Umbilical Cord Placed in Joint Interposition

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: SclerFIX-IP; Treated, devitalised and sterile graft of umbilical cord amniotic membrane	Biological: SclerFIX-IP; Decellularized, viro-inactivated, freeze-dried and sterile allogeneic graft of amniotic membrane of umbilical cord used as an interposition implant in the STT joint

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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 Outcome Measures

Outcome Measure	Measure Description	Time Frame
No apparent joint space anomaly	Joint space evaluated on radiography using Crosby's classification	12 months
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)
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
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
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
Increase of grip strength	Grip strength measured in kg by grip strength test using a dynamometer	3 months, 6 months, 12 months
