Spica splint

A spica splint is a type of orthopedic splint used to immobolize the thumb and/or wrist while allowing other digits freedom to move. It is used to provide support for thumb injuries (ligament instability, sprain or muscle strain), gamekeeper's thumb, osteoarthritis, de Quervain's syndrome, thumb sprains, post-operative use, and post-removal of casting of the hand/thumb.
