What is arthrosis of the shoulder?
Arthrosis is the type of arthritis more commonly known as osteoarthritis. It is the medical term for chronic and slowly progressing wear and tear of a joint, the condition occurs when the cartilage that lies in the joint space between your bones begins to deteriorate.

TM arthrodesis The optimal position of arthrodesis is approximately 20○ of radial abduction and 40○ of palmar abduction. It can be accomplished by several surgical techniques.
What is Trapeziometacarpal osteoarthritis?
Trapeziometacarpal osteoarthritis, also known as osteoarthritis at the base of the thumb or as rhizarthrosis, is a reparitive joint disease affecting the first carpometacarpal joint (CMC1). This joint is formed by the trapezium bone of the wrist and the first metacarpal bone of the thumb.

It is diagnosed by a thorough history, physical examination, and radiographic evaluation. While radiographs are used to determine the stage of disease, treatment is dependent on symptom severity.
