chrisofix product features

Sharp pain, provoked by certain movements of the thumb may draw attention to saddle joint arthritis.

The most common symptom accompanying saddle joint arthritis is sharp pain provoked by strong grasping or pinching. Another typical symptom is that due to the degeneration of the cartilage, the joint is deformed, and the bones that make up the saddle joint may bulge out. 

It is important to recognize these symptoms in time and to take them seriously in order to retain pain free and adequate function of our hand. 

  • Place the forearm into the ready to use orthosis. 
  • Adjust the orthosis to the hand and wrist with gentle pressure, and close the ring around the thumb. 
  • Fasten the bandage around the wrist, on back of the hand and forearm. 

Thanks to the special innovative structure of Chrisofix® saddle joint orthoses with aluminium core – that makes up the frame of the orthosis – it provides adequate stability while maintaining the opportunity for precise and exact fitting.
