Muscles of Elbow Finger Pain

■ Brachioradialis Muscle and Wrist Extensors

Brachioradialis Muscle

Origin

• Supracondylar crest of the humerus (upper two-thirds)

• Lateral intermuscular septum Insertion

Styloid process of the radius Action

• Flexion in the elbow joint

• Brings the forearm into medium position between supination and pronation

Innervation

Radial nerve (C5-C6)

Trigger Point Location

1-2 cm distal of the radius head on the radial side of the forearm approximately in the middle of the muscle belly

Referred Pain

• Back of the hand in the area between the saddle joint of the thumb and the basal joint of the index finger

• Lateral epicondyle

• Radial forearm

Associated Internal Organs

None

Extensor Carpi Radialis Longus Muscle (Fig. 19.53)

Origin

• Lateral supracondylar ridge of the humerus (distal third)

• Lateral intermuscular septum Insertion

Base of the metacarpal bone II (stretch side)

Wrist Extension Pain

Action

Dorsal extension and radial abduction in the wrist

Innervation

Radial nerve (C6-C7)

Trigger Point Location

1 -2 cm distal of the radius head, approximately at the height of the trigger point of the brachioradialis, but further ulnar

Referred Pain

• Lateral epicondyle

• Radial half of the wrist and back of the hand in the area of the metacarpal bones I-III

Associated Internal Organs

None

Extensor Carpi Radialis Brevis Muscle Origin

Lateral epicondyle of the humerus (front side) Insertion

Base of the metacarpal bone II (stretch side) Action

Dorsal extension and radial abduction in the wrist innervation

Radial nerve (C7-C8)

Trigger Point Location

Approximately 5-6 cm distal from the radius head (roughly in the middle of the muscle belly) (see Fig. 19. 53)

Referred Pain

Central area of the wrist and back of the hand

Extensor Carpi Ulnaris Muscle Origin

Lateral epicondyle of the humerus (front side) Insertion

Base of the metacarpal bone V Action

Dorsal extension and ulnar abduction in the wrist

Innervation

Radial nerve (C7-C8)

■ Extensor Digitorum and Indicis Muscles

Extensor Digitorum Muscle (Figs. 19.54,19.55) Origin

Lateral epicondyle of the humerus (front side) Insertion

Middle and end phalangesof fingers 2-5 (indirectly by radiating the four muscle tendons into the dorsal aponeurosis)

Action

Extension of the finger joints

Innervation

Radial nerve (C7-C8)

Trigger Point Location

• Trigger point for the middle finger: 3-4 cm distal and somewhat dorsal of the radius head

• Trigger points for the ring and little finger lie a little distal from there, deep in the muscle belly

Referred Pain

• Lateral epicondyle (sometimes included when ring or little finger are affected)

• Dorsal forearm

• Fingers, except for the end phalanx

Trigger Point Location

Approximately 7-8 cm distal from the lateral epicondyle (see Figs. 19.53 and 19.55)

Referred Pain

Ulnar half of the wrist

Associated Internal Organs

None

The referred pain is felt in different fingers, depending on the position of the trigger point.
