neurapraxia

 [noor″ah-prak´se-ah]
failure of nerve conduction in the absence of structural changes, due to blunt injury, compression, or ischemia.

neur·a·prax·i·a

(nūr'ă-prak'sē-ă), Avoid the misspelling/mispronunciation neuropraxia. Avoid the jargonistic use of this word in the general sense of 'nerve lesion'.
The mildest type of focal nerve lesion that produces clinical deficits; localized loss of conduction along a nerve without axon degeneration; caused by a focal lesion, usually demyelinating, but occasionally ischemic (when of shorter than a few hours' duration), followed by a complete recovery.
See also: axonotmesis.

neurapraxia

/neu·ra·prax·ia/ (-prak´se-ah) usually temporary failure of nerve conduction in the absence of structural changes, due to blunt injury, compression, or ischemia.

neurapraxia

[noo͡r′əprak′sē·ə]
the interruption of nerve conduction without loss of continuity of the axon.

neurapraxia

Neurology Partial or complete conduction block over a segment of a nerve fiber, with temporary paralysis. See Cervical cord neurapraxia, Chronic recurrent root neurapraxia.

neurapraxia

A peripheral nerve injury featuring temporary failure of conduction of impulses, usually due to compression without severance.

neurapraxia

nerve injury resulting in short-term neural dysfunction, followed by complete recovery; see axonotemesis; neurotmesis

neurapraxia (neˈ·r·prakˑ·sē·),

n nerve condition characterized by localized loss of conduction that causes short-term paralysis. There is no degeneration of the axon and complete recovery is usual.

They concluded that this cervical stenosis was the factor that explains the appearance of spinal cord neurapraxia.
Much of the currentknowledge of peripheral nerve anatomy and physiology was observed by Sunderland, who developed the following classification for peripheral nerve lesions: grade I, neurapraxia; grade II, axonotmesis; grade III, mixed neurapraxia and axonotmetic lesion; grade IV, neurotmesis with continuity of the epineurium; grade V, complete nerve section.
Additionally, there were five deaths of unspecified etiology, thee high spinal anesthesias, three transient ischemic attacks, two seizures, two severe headachse, two spinal cord edemas, one brainstem edema with herniation, one brain edema with reversible ischemic neurologic deficit, one cortical blindness due to air embolus, one cervical epidural hematoma, one paraspinal hematoma, one peripheral neurapraxia, and one vasovagal response.
34) They followed the patients for only 28 months, but there was a 33% peri operative complication rate, including alveolus fractures, neurapraxia of the peroneal nerve, and component malposition.
In addition to the known risk of hip arthroscopy, which include iatrogenic damage to the labrum and cartilage and neurapraxia, risks specific to this procedure include but are not limited to damage to the retinacular blood supply and a potential stress riser along the femoral neck.
In an effort to minimize the risk of neurapraxia during supine positioning, a group from Yale reported on a technique where a post is not used intraoperatively.
Although nonadhesive skin traction kits were used, pressure sores were observed in two patients, and one traction group (Group 1) patient, who was treated using 2-kg skin traction, developed neurapraxia.
Electrodiagnostic evaluation of foot drop caused by CPN injury at the neck of the fibula can show neurapraxia (a temporary conduction block), axonotmesis (axonal loss) and reduced motor conduction velocity.
21) Pearle and associates performed and analyzed these transfers on 12 cadaveric specimens and found the radial nerve 2 to 3 cm away from the insertion site of the latissimus dorsi and teres major tendons, (30) and Gerber and coworkers reported a neurapraxia rate of 5%.
Surgical management of the injury may result in radial sensory nerve neurapraxia.
The most common minor complication is transient neurapraxia, with the ulnar nerve the most susceptible.
