CHRISOFIX® ORTHOSES FOR

SADDLE JOINT

World-class Orthoses Developed and Patented in Switzerland

Effective immobilization of thumb is the precondition of optimal efficacy

The osteoarthritis of the thumb is one of the most frequent degenerative joint disorders (3-4 times more frequent by
females than males). The prevalence of patients with active symptoms is assumed to be about 10% of the population
over 60 years. The leading symptom is pain at base of thumb which occurs by grasping or peak-catching (taking the
objects between thumb and index finger, opening a bottle, turning key, etc.). Sudden sharp pain may result in dropping
of the grabbed object. In most cases, the symptoms develop gradually. Constant discomfort and symptom-free periods
may vary over years. The pain might persist at rest, too and the alteration may result eventually in deformities.

THUMB SADDLE JOINT ORTHOSIS FOR OSTEOARTHRITIS

INDICATION

For night and rest use

Immobilisation of the metacarpophalangeal (MCP) and saddle joints of the thumb. Especially, for saddle joint osteoarthritis (rhizarthrosis), distorsions, post-fracture stages of the thumb, and following surgery related to this region, even as night splint.

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 adjustments, readjustments (e.g. after soft tissue swelling is reduced) can be made without removing the orthosis.

Place the hand into the preshaped orthosis.
Shape the orthosis to the hand with gentle pressure, and close the ring around the thumb.
Fasten the bandages on the back of hand and the wrist.

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.
