Saddle joint orthosis – Night use



For night and rest use  Chrisofix world class orthoses - night

The night use version of the saddle joint orthesis (long Rizorthezis) serves to fixate the base joint of the thumb MCP-metacarpophalangeal joint) and the saddle joint (CMC). It may also be used to good effect in cases of saddle joint arthritis for night time splinting and also for fixation of the metacarpal of the thumb or the saddle joint following injury, sprains or even in the rehabilitation phase following fractures.

It may also be utilized as complementary treatment to surgery performed on fractures of the thumb metacarpal (Benett, Rolando, Winterstein fractures).

Application and adjusting

The ready to adjust Chrisofix® orthoses have to be adjusted directly on the injured/diseased body part. The rough adjustment (bending) has to be performed on a non-injured limb of similar size. Fine adjust-ments, readjustments (e.g. after soft tissue swelling is reduced) can be made without removing the orthosis.

  • 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 on back of the hand, around the wrist and forearm.

To remove the orthosis, it is not necessary to open the strap on the thumb and back of the hand; the hand can simply be pulled out from and later shifted back into the fixation. Frequent bending and stretching of the orthosis can damage its stability; these must be restricted to the necessary minimum.
