Intrinsic plus hand: Painful Finger flexion and extension

Intrinsic plus hand describes a rare and painful contracture of the intrinsic hand muscles with excessive flexion at the metacarpophalangeal joints and extension at the interphalangeal joints. Resulting from many causes to include trauma and neurologic injury, intrinsic plus hand can involve any number of fingers. Emergency department (ED) assessment should include evaluation for cerebrovascular injury, infection, compartment syndrome, and deep vein thrombosis (DVT). Conservative splinting is generally unsuccessful and ultimately requires operative intervention.
