RhizoLoc® Product


Stabilizing orthosis for stabilization of the thumb saddle and first metacarpophalangeal joints.

Following thumb joint injuries, such as tears or sprain to the collateral ligaments ("skier's thumb"), or for indications of osteoarthritis (arthrosis of first carpometacarpal joint) or irritation, RhizoLoc stabilizes the thumb saddle and metacarpophalangeal joint. A Velcro® tab allows the mobility of the joint to be limited as treatment requires.

  • comfortable and stable
  • easy to put on and take off
  • breathable material

Good news for skier's thumb sufferers!

The RhizoLoc thumb orthosis has an individually adaptable aluminum stay which stabilizes the thumb saddle and metacarpophalangeal joint. This allows for optimal healing of the affected collateral ligaments. A special Velcro tab can be adjusted in order to limit the movement of the metacarpophalangeal joint and to immobilize it as treatment requires.

Secure and comfortable

With its Velcro® fastenings, the orthosis can easily be put on and taken off by the patient. The orthosis can be adapted to the patient's individual thumb size by means of the adjustable thumb tab. The breathable material with its integral pores allows air to circulate, thereby preventing the skin underneath from becoming sweaty or itchy. The RhizoLoc therefore sits securely in an anatomically correct and comfortable position on the hand for effective therapy.
