neurotmesis

neurotmesis

 [noor″rot-me´sis]
partial or complete severance of a nerve, with disruption of the axon and its myelin sheath and the connective tissue elements.

neu·rot·me·sis

(nū'rot-mē'sis),
A type of axon loss lesion resulting from focal peripheral nerve injury in which, at the lesion site, the nerve stroma is damaged to varying degrees, as well as the axon and myelin, which degenerate from that point distally; with the most severe neurotmesis lesions, the gross continuity of the nerve is disrupted. See: axonotmesis, neurapraxia.

/neu·rot·me·sis/ (noor″ot-me´sis) partial or complete severance of a nerve, with disruption of the axon and its myelin sheath and the connective tissue elements.

neurotmesis

[noo͡r′ōtmē′sis]
Etymology: Gk, neuron + tmesis, cutting apart
a peripheral nerve injury in which the nerve is completely disrupted by laceration or traction. It requires surgical approximation, with unpredictable recovery.

neurotmesis

complete division of a nerve, usually as the result of accident or trauma; nerve repair does not normally occur without surgical intervention

In an attempt to classify the physical and functional state of the damaged nerve trunk, these injuries have also been classified into three broad categories by Seddon (5): neurapraxia, axonotmesis, and neurotmesis [Table 2].
Therefore differentiating between neuropraxia, axonotmesis, and neurotmesis is essential, but it is time dependent and requires follow-up EDX studies as well as histologic evidence.
Based on the degrees of damage in the nerve and surrounding connective tissue, peripheral nerve damage may be classified as neurapraxia, axonotmesis, and neurotmesis, with the latter being a severe type of peripheral nerve injury [86].

In cases of neurotmesis, the endoneural tubes are disrupted which can result in misdirected axonal regrowth (ie, synkinesis), which could potentially impact subsequent treatment where needle position is based on bony anatomic landmarks.
Neurotmesis is a complete severing of axon and connective tissue; recovery is not expected without surgical repair.
However, the major kinds of experimental lesion to this nerve are axonotmesis by crushing (6) or neurotmesis followed by microsurgical nerve reconstruction (7).
16) showed in a case report that EMG is fundamental for the localisation of sciatic damage following THR, in order to identify the mechanism, severity and prognosis, and recommended that an exploration procedure on the nerve be performed in the event of neurotmesis.

El desconocimiento de las relaciones anatomicas del CAI en los diferentes procedimientos quirurgicos puede lacerar, comprimir o estirar el nervio (8, 9) generando lesiones como neuropraxia, axonotmesis y neurotmesis.
Neurotmesis is the interruption of neurites, myelin, and the nerve envelopes (at least the endoneurium and the perineurium, in crush injury, for example).
Ultrasound examination identified a traumatic neuroma just before the ulnar nerve branched into sensory termini and excluded neurotmesis.
