An orthosis which covers the hand and forearm, which secures the wrist joint. It is most often used to correct the placement of the radiocarpal joint from excessive bending in the hand or elbow.
With very small children, an orthosis with a support for the fingers and thumb is often used, allowing for the use of separators for the fingers. With older patients, an orthosis without support for the fingers is often used, in order to facilitate manual function of the limb.
As with the lower limbs, a rigid orthosis is often used as well as an orthosis with a therapeutic wrist joint in order to release the contracture of this joint. These are constructed of thermoplastic materials, breathable fabrics, and resins which result in a significantly reduced weight for the orthosis.
