Final answer:
The best type of splint for an anticipated deformity with an elbow burn is a posterior long arm splint.
Step-by-step explanation:
When treating a burn injury to the elbow, the best type of splint to use would be a posterior long arm splint. This type of splint immobilizes the entire arm from the hand to the upper arm, providing stability and support. It helps to prevent any further damage, reduces pain, and promotes healing.
In the case of an anticipated deformity with an elbow burn, the posterior long arm splint can help to maintain proper alignment of the bones, preventing any misalignment or deformity.
