Splint

A splint is a supportive device, often made of rigid material, foam, or moldable plastic, that holds an injured limb or joint in place. Unlike a cast, which fully encircles the limb, a splint usually covers only part of it and can sometimes be removed or adjusted, which makes it useful for injuries that may swell, for early-stage fractures, or for situations where a temporary or adjustable level of support is needed.

Splints are commonly used right after an injury, before a definitive treatment plan is set, or for less severe fractures, sprains, and soft tissue injuries that don't require full immobilization. They are also used during parts of fracture healing or recovery from certain procedures, and sometimes after hardware removal or surgery as the area regains strength.

The choice between a splint, a cast, or another form of immobilization depends on the type and location of the injury, how stable it is, and how healing is progressing. These decisions, along with how long a splint should be worn and when it's safe to resume normal activity or weight-bearing, are best made by the treating doctor or orthopedic provider, since removing support too early or keeping it on too long can both affect healing.
