OK sign. An inability to oppose the tips of the thumb and index finger due to weakness involving the flexor pollicis longus and the flexor digitorum profundus to the index finger. The patient is only able to touch the finger pads together, not the tips, forming a crude triangle rather than a circle. The OK sign appears in lesions involving the anterior interosseous nerve or the anterior interosseous fascicles in the median nerve, usually in the brachial plexus or the upper arm.
