Patients may experience poorly localised, transient pain in the wrist, ie where the sensory branch of the AIN is mapped in the brain. The pain is sometimes referred into the cubital fossa and elbow pain has been reported as being a primary complaint.⁠ The characteristic severe impairment of the pincer movement of the thumb and index finger is most striking. Clinical signs In a pure lesion of the<unk><unk>  nerve there is weakness of the long flexor muscle of the thumb (Flexor pollicis longus), the deep flexor muscles of the index and middle fingers (Flexor digitorum profundus I & II), and the pronator quadratus muscle. There is no sensory deficit since the<unk><unk>  nerve has no cutaneous branch to skin, but there is a large sensory branch to the volar carpus, and transient wrist pain may be experienced.
