WebThe microstructure of nerve trunks provides the basis for a classification of nerve injuries into five degrees of severity with partial and mixed types—each with a clearly defined pathology and distinguishing clinical features. Following a transection injury, changes occur in the severed axons, endoneurial tubes, fasciculi, and nerve trunk. WebFeb 12, 2024 · In 1942, Seddon classified the severity of peripheral nerve injury (PNI) in three types; neurapraxia, axonotmesis, or neurotmesis. A few years later, in 1951, Sunderland classified them in five different degrees. Neurapraxia is the mildest type of PNI commonly induced by focal demyelination or ischemia.

WebInjury Classification Seddon2 classified nerve injuries into three major groups: neurapraxia, axonotmesis, and neurotmesis (Table 1). Neurapraxia is character-ized by local myelin damage, usual-ly secondary to compression. Axon continuity is preserved, and the nerve does not undergo distal de-generation.
