Answer :
Final answer:
The MOST appropriate splinting position for a Boutonniere deformity is option 3: proximal interphalangeal joint in extension and the distal interphalangeal joint in flexion.
Explanation:
The MOST appropriate splinting position for a Boutonniere deformity is option 3: proximal interphalangeal joint in extension and the distal interphalangeal joint in flexion. A Boutonniere deformity is characterized by flexion of the proximal interphalangeal joint and extension of the distal interphalangeal joint.
Immobilizing the proximal interphalangeal joint in extension and the distal interphalangeal joint in flexion helps to correct the deformity and promotes healing by maintaining the correct alignment of the fingers.
