Describe the route that the radial nerve takes?
Travels posterior to the humerous and travels inside the radial grove alongside the profunda brachii artery (branch of the brachial artery), it then passes lateral to the lateral epicondyle
Which part of the humerous articulates with the radius head?
Capitulem
Where is the coracoid fossa located and what is its significance during flexion of the elbow?
Coranoid fossa lies superior to the ulnar bone and during flexion the coranoid process of the ulnar bone sits within this fossa
What part of the humerous articulates with the ulnar head?
Trochlear
Where does the tendon of brachialis muscle attach onto inferiorly?
Ulnar
What holds the radius against the capitulem?
Ring of annular ligament
Where does the tendon of biceps brachii muscle attach onto inferiorly?
Radius
What lies in-between the radius and ulnar?
Interroussus membrane
What muscles bring about supernation?
Supernator
Biceps brachii
What muscles bring about pronation?
Pronator teres
Pronator quadratus
Name the 4 distal carpal bones from medial to lateral?
Hamate
Capitulate
Trapezoid
Trapezium
Name the 4 proximal carpal bones from medial to lateral?
Pisiform
Triquetrium
Lunate
Scaphoid
Name all of the superficial muscles of the anterior compartment of the forearm?
Pronator teres Flexor carpi radialis Palmaris longus (may be absent) Flexor digitorum superficialis Flexor carpi ulnaris
What is the nerve innervation of the superficial muscles of the anterior compartment of the forearm? Which muscle is an exception to this and what is its nerve supply?
Median nerve
Flexor carpi ulnaris
Ulnar nerve
Name all of the deep muscles of the anterior compartment of the forearm?
Pronator quadratus
Flexor digitorum profundus
Flexor pollicis longus
Which muscle of the forearm receives bi-nerve innervation, and what two nerves supply this?
Flexor digitorum profundus (deep/anterior compartment)
Ulnar and median nerve
Where do all of the superficial muscles of the anterior compartment attach onto superiorly?
Medial epicondyle
Name all of the superficial muscles of the posterior compartment of the forearm?
Brachioradialis Extensor carpi radialis longus Extensor carpi radialis brevis Extensor digitorum Extensor digiti minimi Extensor carpi ulnaris
Name all of the deep muscles of the posterior compartment of the forearm?
Supernator (wank muscle) Abductor pollicus longus Extensor pollicus brevis Extensor Pollicus Longus Extensor indicus
What is the nerve supply on both of the posterior compartments of the forearm?
Radial nerve
What fracture concerning the wrist is likely to occur in older people?
Colles fracture (distal radius)
What fracture concerning the wrist is likely to occur in younger people?
Scaphoid fracture - this can lead to avascular necrosis
Name the five P’s associated with compartment syndrome?
Pain Paraesthesia Pallor Paralysis Pulselessness
What is the superior attachment of the extensor compartment of the forearm muscles?
Lateral epicondyle
Name the branch from the median nerve which supplies the deep flexor compartment of the forearm?
Anterior interrousus nerve
