BOARD 1
1. Nerves of right arm


BOARD 2
1. Orientation view
2. Cross section of elbow


BOARD 3
1 - 6. Dermatomes of upper extremity


BOARD 4
1. Ulnar nerve distribution, palmar view showing musculature
2 - 3. Cutaneous innervation


BOARD 5
1 - 2. Position of patient


BOARD 6
1. Normal anatomy: nerve distribution through musculature of right arm


BOARD 7
1. Axilla (brachial plexus): anterior view


BOARD 8
1. Injury to the sheath of the nerve, which can 2. heal and not interrupt Nerve fully transected, long term, no signal
3. Swelling of the nerve causes signal to be interrupted, neuroma
4. Swelling of the muscle around the nerve, nerve compression


BOARD 9
1. Dec 13, 2005
Right ulnar nerve transposition: orientation view, ulnar nerve compression in elbow of right arm
2. Ulnar nerve detail, surgical opening
3. Ulnar nerve transposition
4. Ulnar nerve transposed


BOARD 10
1. Two neuromas in medial antebrachial cutaneous nerve
2. Detail: neuromas in medial antebrachial cutaneous nerve, both in a dense collection of fibrous tissue and multiple terminal nerve sprouts
3. Both neuromas excised, the nerves transected in normal nerve tissue and the ends implanted into conduits
4. Post-op


BOARD 11
1. Orientation view showing medial antebrachial cutaneous nerve location in relation to the ulnar nerve
2. Cross section: normal medial antebrachial cutaneous nerve
3. Cross section: scar from previous incision causes scarring beneath into soft tissue which irritates the medial antebrachial cutaneous nerve
4. Adhesions and irritation cause irregular nerve regeneration
5. Neuroma is formed at site of previous incision
