| 词条 | Spica splint |
| 释义 |
A spica splint is a type of orthopedic splint used to immobilize the thumb and/or wrist while allowing the 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 or a scaphoid fracture. It is also suitable for post-operative use or after removal of a hand/thumb cast. A spica splint may consist of a metal enclosed in a fabric or moulded thermoplastic, which is pliable and can be moulded according to the shape and size of the hand. Velcro strips are used to secure and maintain the splint on the hand and help in comfortably fitting the splint to a variety of hands. Even injuries like metacarpal fractures and wrist fractures can benefit from spica splints. Thumb Spica splints (cock-up splints) are used for acute injuries like sprains and fractures. A dynamic cock-up splint is a special kind of spica splint, which is used in nerve palsies of the hand for preventing contractures and physical therapy. Thermoplastic splints are heat-sensitive; very hot water (above 60 °C) or prolonged exposure to direct sunlight can cause the material to lose its shape.
