Xiapex In a normal joint, cartilage covers the end of the bones and serves as a shock absorber to allow smooth, pain-free movement. In osteoarthritis OA, or "degenerative arthritis" the cartilage layer wears out, resulting in direct contact between the bones and producing pain and deformity. One of the most common joints to develop OA in the hand is the base of the thumb. The thumb basal joint, also called the trapeziometacarpal TMC joint, is a specialized saddle-shaped joint that is formed by a small bone of the wrist trapezium and the first bone of the thumb metacarpal.

The saddle shaped joint allows the thumb to have a wide range of motions, including up, down, across the palm, and the ability to pinch.

Pressure and movement such as twisting will produce pain at the joint.

A grinding sensation may also be present at the joint. X-rays are used to confirm the diagnosis, although symptom severity often does not correlate with x-ray findings. Severe bilateral rhizarthrosis: joint destruction, deformity and bone contact Less severe thumb arthritis will usually respond to non-surgical care such as : Avoiding activities that cause pain, if possible.

Splinting rigid and non-rigid splints. Limited steroid injection and viscosuplementation Surgery is a last resort, as the symptoms often stabilise over the long term and can be controlled by the non-surgical treatments above.

Patients with advanced disease or who fail non-surgical treatment may be candidates for surgical reconstruction. A variety of surgical techniques are available that can successfully reduce or eliminate pain.
