Dit Day 1 - Nerves Up The Upper Limb

Front 1

Axillary nerve: cause of lesion and consequences

Back 1

Lesioned by fracture of the surgical neck of the humerus.
Lesion results in loss of deltoid sensation and motor. Can't raise arm more than 10 degrees.

Front 2

Radial nerve: cause of lesion and consequences.

Back 2

Cause: Proximally - Saturday night palsy
In spiral groove - fracture of midshaft humerus.
Distal/deep: subluxation of radius.
Consequences: loss of extensors (brachioradialis, extensors, supinators, triceps), loss of sensation over posterior arm, dorsum of hand.

Front 3

Proximal Median nerve: cause of lesion and consequences

Back 3

Lesioned by: Supracondylar humerus fracture
Consequence: loss of lateral finger flexion, wrist flexion

Front 4

Distal median nerve: cause of lesion and consequence

Back 4

Cause: carpal tunnel syndrome
Consequence: ape hand, loss of thumb opposition.

Front 5

Proximal Ulnar nerve: cause of lesion and consequence:

Back 5

Cause: fracture of medial epicondyle - funny bone
Consequence: loss of medial finger flexion, loss of sensation over medial 1.5 fingers.

Front 6

Distal Ulnar nerve: cause of lesion and consequence

Back 6

Cause:Fracture of hook of hamate (fallin on outstretched hand)
Consequence; loss of abduction/adduction of fingers (interossei), loss of extension of 4th and 5th fingers (lumbricals)

Front 7

Musculocuteneous nerve: cause of lesion and consequence

Back 7

cause: upper trunk compression
Loss of arm flexion at elbow: biceps, brachialis, coracobrachialis. Lateral forearm sensory loss.

Front 8

Erb-Duchenne Palsy

Back 8

damage to upper trunk of brachial plexus ( C5-C6)
Causes waiters tip hand.

Front 9

Klumpke's palsy and thoracic outlet

Back 9

Affects inferior trunk - C8, T1.
Atrophy of interossei, thenar and hypothenar, sensory deficits on medial side of forearm

Front 10

Long Thoracic Nerve: causes of lesion and consequences

Back 10

Cause: mastectomy
Consequence - loss of serratus anterior fxn, winged scapula
