Hand-based thumb spica casting.
A hand-based thumb spica cast can be used to protect the metacarpophalangeal (MCP) and interphalangeal (IP) joints of the thumb after uncomplicated ulnar collateral ligament (UCL) sprains and certain other thumb injuries. The cast allows continued participation in many activities, letting the patient grip an implement and move the wrist joint but immobilizing the thumb joints.
