ADDUCTOR MUSCLE TEST ( ADDUCTOR POLLICIS )
BOOK TEST =
ASK PATIENT TO HOLD BOOK BETWEEN THUMB AND INDEX FINGER , THERE WILL BE FLEXION AT IP JOINT OF THUMB , THIS WILL BE MORE PRONOUNCED WHEN EXAMINER TRIES TO PULL THE BOOK
ABDUCTOR MUSCLE TEST
ASK TO PLACE HAND ON TABLE AND ABDUCT THE THUMB AGAINST RESISTANCE
FLEXOR MUSCLES TEST
ASK TO PALMAR FLEX THE WRIST AGAINST RESISTANCE
INTEROSSEI TEST
CARD TEST
EGAWA TEST
TEST FOR 1ST DORSAL INTEROSSEI
CARD TEST
INABILITY TO HOLD CARD BETWEEN TWO EXTENDED FINGERS WHEN EXAMINER TRIES TO PULL CARD
EGAWA TEST
PALM PLACED FLAT ON TABLE AND PATIENT ASKED TO MOVE MIDDLE FINGER SIDEWAYS
1ST DORSAL INTEROSSEI TEST
PATIENT ASKED TO ABDUCT INDEX FINGER AGAINST RESISTANCE
SCREENING TEST FOR ULNAR NERVE
TIP OF LITTLE FINGER ( AUTONOMOUS ZONE ) TESTED FOR SENSATION .
TARDY ULNAR NERVE PALSY
LATE ULNAR NERVE INJURY
CAUSE = CUBITUS VALGUS DEFORMITY , MEDIAL EPICONDYLE # , MALUNION OR NON UNION OF LATERAL EPICONDYLE , DISLOCATION OF ELBOW , RECURRENT SUBLUXATION , NERVE CONTUSION
CLINICAL FEATURES = TINGLING , NUMBNESS , WEAKENING OF MUSCLES , TINEL PERCUSSION POSITIVE
TT = SUPRACONDYLAR OSTEOTOMY , TRANSPOSITIONING OF ULNAR NERVE
CLAW HAND
HYPEREXTENSION OF MP JOINT , FLEXION OF IP JOINT .
TYPES =
TRUE ULNAR CLAW HAND : MEDIAN NERVE AND ULNAR NERVE INVOLVED
ULNAR CLAW HAND : ONLY ULNAR NERVE INVOLVED
CAUSE =
ULNAR NERVE PALSY
MEDIAN NERVE PALSY
LEPROSY
COMPARTMENT SYNDROME OF HAND
ULNAR PARADOX
HIGHER THE LESION IN ULNAR NERVE LESS IS THE DEFORMITY AND VICE VERSA
WHEN ULNAR NERVE IS INJURED IN HIGHER LEVEL , THEN MEDIAL HALF OF FDP IS ALSO INJURED SO THERE IS LESS FLEXING AT IP JOINT , SO ULNAR NERVE DEFORMITY IS LESS VISIBLE , THUS CALLED ULNAR PARADOX
