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.

Conditions

Osteoarthritis Hand

Keywords

ScaphoTrapezioTrapezoid OsteoArthritis (STT OA)

Outcome Measures

Primary Outcomes (1)

• 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 Outcomes (6)

• Absence of inflammatory reactions and good local tolerance of the implant

  Through study completion (12 months)

• Decrease of pain related to STT OA

  1 month, 3 months, 6 months, 12 months

• Improvement of functional activities involving the thumb

  1 month, 3 months, 6 months, 12 months

• Increase of thumb strength

  3 months, 6 months, 12 months

• Increase of grip strength

  3 months, 6 months, 12 months
