Ape hand deformity is a deformity in humans who cannot move the thumb away from the rest of the hand. It is an inability to
opponens pollicis muscle function. The name "ape hand deformity" is misleading, as some apes do not have opposable thumbs.[citation needed
]
It can occur with an injury of the
thenar muscles and opponens pollicis muscle.[2]
Ape hand deformity is one aspect of median nerve palsy, which is usually caused by deep injuries to the arm, forearm and wrist area.[citation needed]
