Definition
postplexus or terminal nerve lesion causing paresis/paralysis and anesthesia |

Term
Hereditary brachial plexus neuropathy |
|
Definition
Acute onset of shoulder pain and loss of brachial plexus function during the immediate postpartum period; FHx of similar events; recurrent but benign. |
|
|
Term
Neoplastic component of brachial neuropathy |
|
Definition
CA or tumor development in the plexus. C8 and T1 are favored with the CA moving up. |
|
|
Term
|
Definition
temporary failure of conduction without loss of axonal continuity. Spontaneous recovery with good recovery of function (within minutes to hours) |
|
|
Term
|
Definition
Lesion resulting in wallerian degeneration, without loss of endoneurial tubes. Spontaneous recovery with good recovery of function (several months to over a year) |
|
|
Term
|
Definition
Axons and endoneurial tubes are disrupted. Both partial retrograde and complete anterograde wallerian degeneration. Surgical repair needed. Mismatch repair results in partial recovery of function. |

Term
Now, what happens if you lesion just the sensory components of a single spinal nerve, e.g., C6? |
|
Definition
Lesioning spinal nerve C6, its ventral ramus, or its dorsal root, will produce hypesthesia distributed in all cutaneous “patches” having the C6 dermatome. However, there will be severe hypesthesia or even anesthesia in the autonomous region of the C6 dermatome (skin over thenar eminence and thumb pad). |
|
|
Term
What happens if a terminal nerve or its cutaneous branch is lesioned? |
|
Definition
Lesioning the terminal cutaneous nerve (e.g., the cutaneous brs. of the musculocutaneous nerve) produces severe hypesthesia and even anesthesia of the dermatomes represented in its patch because both the dermatomes and their overlaps are carried in that cutaneous nerve and thus, are “knocked out” |

Posterior interosseous syndrome (supinator syndrome) |
|
Definition
Wrist extension possible, but can’t extend digits properly. |
|
|
Term
|
Definition
Entrapment of superficial radial nerve as it emerges between the tendons of the brachioradialis and extensor carpi radialis longus (Tinel sign). |
|
|
Term
de Quervain’s tenosynovitis |
|
Definition
(inflammation of the tendon sheaths in first extensor compartment of the wrist). Passive volar bending of thumb stretches the inflammed tendons producing pain (positive Finkelstein’s test). |
|
|
Term
|
Definition
pain is more distal, generally over the mobile wad. In addition, provocative tests such as resistance to supination, and resistive extension of middle finger produces pain over radial tunnel. |
|
|
Term
best test to dx radial nerve lesion |
|
Definition
The single best test for a radial nerve lesion is having the patient dorsally raise the thumb from a flat surface (extensor pollicis longus). The patient will not be able to perform this test with a severe radial nerve lesion. |

|
|
Term
|
Definition
Abnormal episodic vasospasm of the digits in response to cold exposure. Upon warming, the affected digits undergo reactive hyperemia, becoming engorged with blood. There is a characteristic biphasic or triphasic color response of the affected digits: pallor to cyanosis and upon rewarming, rubor (redness). During the hyperemic phase (rubor), there is considerable pain and throbbing. |
