Agnew splint

A splint for fractures of the patella and metacarpus.

air splint

A lightweight splint for immobilizing fractured or injured extremities. It is usually an inflatable cylinder, open at both ends, that becomes rigid when inflated, thus preventing the part confined in the cylinder from moving.
SYN: SEE: blow-up splint; SEE: inflatable splint
Descriptive text is not available for this imageBecause of the tendency for the air cast to straighten out the limb as it is inflated, this device should not be used to immobilize joint dislocations or fractures with gross displacement.

finger splint

A padded strip of malleable metal or plastic used to immobilize a fractured finger. As an alternative, the injured finger is often “buddy taped” to an adjoining finger for support.

Any orthosis that lacks movable parts and is used for positioning, stability, protection, or support.

Stromeyer splint

SEE: Stromeyer splint

sugar tong splint

A splint commonly used instead of a cast to immobilize a Colles fracture after it has been reduced. The splint permits the affected arm to swell without being compressed within the confines of the cast yet maintain its alignment. Follow-up diagnostic images of the fracture are typically obtained 5 to 7 days after placement of the splint to ensure that adequate reduction of the fracture is maintained.

temporary removable splint

Any of a variety of splints for temporary or intermittent support and stabilization of the teeth.

tenodesis splint

A splint allowing pinching and grasping movements through wrist extensors.
SYN: SEE: wrist-driven flexor hinge hand splint

Thomas splint

SEE: Thomas splint

traction splint

A splint that provides continual traction to a midshaft lower extremity fracture.

vacuum splint

A negative-pressure splint to immobilize the extremities or torso after an injury. It may be used to safely transport the injured person. The splint consists of a nylon appliance filled with Styrofoam-like beads. The appliance is fitted around the injured body part and air is removed using a vacuum pump. As air is removed, the appliance conforms to the body part without straightening the limb.
