SOT Thumb Orthosis

The orthosis is designed to restrict movements in CMC and MCP joints, support the hand’s arch and position the thumb’s joints and muscles in a comfortable and desirable resting position. To avoid overstretched ligaments that can lead to subluxation in the joint. The orthosis has an adjustable aluminum core that can easily be shaped to fit individual anatomy. The orthosis can be adjusted as the contracture changes. The orthosis can be machine washed with cover attached at 40oC. The smooth design makes it an excellent alternative to custom made thumb orthosis.

When extra support is needed for the wrist, the SOT Thumb orthosis can be used together with a wrist brace, such as 35204 Selection Soft or 35207 Selection Open Wrist. For patients with adduction contracture that has developed due to forearm fracture immobilization, SOT thumb orthosis combined with a wrist orthosis may be advantageous for night-time treatment.

Recommended Range Of Application:

Osteoarthritis*, rheumatoid arthritis, adduction contracture of the thumb, overload injury of the CMC joint.
