<prompt> All of the following show ulnar nerve injury EXCEPT:Clawing of medial 2 digitsAbductor pollicis palsyAdductor pollicis palsyWeak grip  <response>: Ans. B Abductor pollicis palsyRef: BDC, 6th ed. vol. I pg. 109-110, 120 In ulnar nerve palsy grip is weak due to paralysis of intrinsic muscles all interossei, lateral 3rd 4th lumbricals, hypothenar and adductor pollicis muscles. Sensory supply of ulnar nerve is medial 1 12 fingers. Abductor pollicis is supplied by median nerve. Finger drop i.e. loss of extension of metacarpophalangeal joint is seen in Radial Posterior interosseous nerve palsySigns of Ulnar Nerve palsy remembered as BCDEF Book testFromet sign: While holding the book between thumb and rest of hand, there is overaction of flexor pollicis longus due to adductor pollicis nerve palsy. Claw hand: Clawing of medial 2 digits Card test: for testing palmar interossei, i.e. adduction of fingers. PAD aDDuctor pollicis paralysis: Adduction of thumb lost Egawas test: To test dorsal interossei i.e. abduction of fingers DAB. Froment signExtra Mile In low ulnar nerve palsy forearm muscles are spared but the clawing is more as compared to high ulnar n. palsy this phenomenon is known as ulnar paradox. Lower the lesion, more the clawing.
