The highlighted area is closely related to the tendon of

1 Flexor pollicis longus

2 Extensor carpi ulnaris

3 Abductor Pollicis Longus

4 Extensor pollicis longus

5 Flexor carpi radialis


The highlighted area is closely related to the tendon of

1 Flexor pollicis longus F

2 Extensor carpi ulnaris F

3 Abductor Pollicis Longus F

4 Extensor pollicis longus T

5 Flexor carpi radialis F

This is Lister’s tubercle. It is closely related to the extensor pollicis longus tendon. This tendon can rupture following a malunited fracture of the distal radius.

MusclesThe following muscles attach to the radius

1 Extensor digitorum

2 Brachioradialis

3 Flexor digitorum superficialis

4 Flexor digitorum profundus

5 Extensor Carpi Radialis Longus


1 Extensor digitorum F

2 Brachioradialis T

3 Flexor digitorum superficialis T

4 Flexor digitorum profundus F

5 Extensor Carpi Radialis Longus F

Extensor digitorum originates from the lateral epicondyle and inserts onto the extensor expansion of digits 2-5.Brachioradialis originates from the lateral supracondylar ridge of the humerus and inserts onto the lateral surface distal aspect of radius. Flexor digitorum superficialis originates from the medial epicondyle of humerus, ulnar collateral ligament and coronoid process of ulna; Radial head: superior half of anterior border of radius and it inserts onto middle phalanges of digits 2 – 5.Flexor digitorum profundus originates from the proximal 3/4 of medial and anterior surfaces of ulna and interosseous membrane and inserts onto the base of the distal phalanx of digits 2 – 5Extensor Carpi Radialis Longus originates from the lateral supracondylar ridge of the humerus and inserts onto the base of the 2nd metacarpal

1 Extensor Pollicis Brevis T

2 Extensor Pollicis Longus F

3 Pronator Quadratus T

4 Abductor Pollicis Longus T

5 Extensor Carpi Radialis Brevis F

Extensor Pollicis Brevis originates from the posterior surface of the radius and interosseous membrane and inserts onto the base of proximal phalanx of thumbExtensor Pollicis Longus originates from the posterior surface of middle 1/3 of ulna and interosseous membrane and inserts onto the base of distal phalanx of thumbPronator Quadratus originates from distal 1/4 of anterior surface of ulna and inserts onto the distal 1/4 of anterior surface of radius.Abductor Pollicis Longus originates from the posterior surfaces of ulna, radius and interosseous membrane and inserts onto the base of 1st metacarpalExtensor Carpi Radialis Brevis originates from the lateral epicondyle of the humerus and inserts onto the base of the 3rd metacarpal
