Axonotmesis is usually the result of a more severe crush or contusion than neurapraxia, but can also occur when the nerve is stretched ( without damage to the epineurium ).
12.
The mildest grade is referred to as neurapraxia and is characterized by a reduction or complete blockage of conduction across a segment of nerve while axonal continuity is maintained and nerve conduction is preserved.
13.
This classification uses five different degrees of nerve injury, the first one being the least severe and the equivalent to neurapraxia and the most severe being the fifth degree and having the same classification as neurotmesis.
14.
Taken together, these changes are intended to produce compliance via transitory neurapraxia ( temporary muscle pain, spasm and paralysis due to nerve injury ) instead of the bone fractures and cerebral concussion which characterized their earlier use.

The "'Gartland classification "'is a system of categorizing supracondylar humerus fractures, clinically useful as it predicts the likelihood of associated neurovascular injury, such as anterior interosseous nerve neurapraxia or brachial artery disruption.
16.
"' Neurapraxia "'is a disorder of the peripheral nervous system in which there is a temporary loss of motor and sensory function due to blockage of nerve conduction, usually lasting an average of six to eight weeks before full recovery.
17.
Two patients developed temporary neurapraxia secondary to arm extension during treatment, The authors further noted that complete target tumor ablation verified by CT was achieved in 46 of the 69 tumors treated with IRE ( 66 % ), while most treatment failures occurred in renal and lung tumors.
18.
A more recent and commonly used system described by the late Sir Sydney Sunderland, divides nerve injuries into five degrees : "'first degree "'or neurapraxia, following on from Seddon, in which the insulation around the nerve called myelin is damaged but the nerve itself is spared, and "'second through fifth "'degree, which denotes increasing severity of injury.
