A hand imitating an<unk> . The metacarpophalangeal joints of the 4th and 5th fingers are extended and the Interphalangeal joints of the same fingers are flexed. An<unk> , also known as<unk>  hand, or spinster's<unk>  is a deformity or an abnormal attitude of the hand that develops due to<unk>  nerve damage causing paralysis of the lumbricals. A<unk>  hand presents with a hyperextension at the metacarpophalangeal joints and flexion at the proximal and distal interphalangeal joints of the 4th and 5th fingers. The patients with this condition can make a full fist but when they extend their fingers, the hand posture is referred to as<unk>  hand. The ring- and little finger can usually not fully extend at the proximal interphalangeal joint (PIP). This can be commonly confused with the "hand of benediction or pope's blessing", which is caused by proximal (at elbow level) median nerve damage.
