Wrist Extrinsic

Question 1

Flexor Carpi Ulnaris

Answer 1

Resist wrist flexion and ulnar deviation and tendon inserts onto pisiform trace tendon proximally to belly

Question 2

Flexor carpi radialis

Answer 2

Resist flexion and radial deviation and tendon just lateral to palmaris longus

Question 3

palmaris longus

Answer 3

Resist wrist flexion with cupped fingers and palpate tendon which starts above the wrist centrally

Question 4

flexor digitorum superficialis

Answer 4

Wiggle fingers and palpate tendons in space between FCU and PL tendons and the belly is upper medial forearm

Question 5

flexor digitorum profundus

Answer 5

Resist DIP flexion
Tendons – palpate palmar aspect middle phalanx.
Belly –palpate posterior border proximal ulna.
flexes fingers especially at DIPJ

Question 6

flexor pollicis longus

Answer 6

Resist IP flexion and palpate tendon on palmar surface of proximal phalanx.

Question 7

extensor carpi ulnaris

Answer 7

Resist wrist extension and ulnar deviation.
Palpation:
Tendon: just lateral ulnar styloid, inserting into metacarpal V. Trace tendon proximally to belly.

Question 8

extensor carpi radialis longus

Answer 8

Resist extension and radial deviation.

Palpation: Both tendons cross wrist joint 1cm medial to radial styloid. Trace tendon proximally to belly.

Question 9

extensor carpi radialis brevis

Answer 9

during wrist extension and radial deviation palpate just proximal to the dorsal aspect of the wrist and approximately 1cm medial to the radial styloid process, the tendon may be felt during extension and traced to the base of the third metacarpal, particularly when making a fist.

Question 10

extensor digitorum

Answer 10

Palpation: Tendon crosses inferior radioulnar joint. Trace tendon proximally to belly.

Question 12

extensor indicis

Answer 12

Resist index finger extension / wiggle finger.

Palpation: Tendon joins ED tendon just proximal to MCP joint from ulnar side.

Question 13
