Peripheral nerve injury

Peripheral nerve injury

Seddon classified nerve injuries into neurapraxia, axonotmesis and neurotmesis: /uni25CF Neurapraxia – no loss of nerve sheath continuity or periph eral Wallerian degeneration. If the pressure is removed from the nerve, recovery potential is good but may take months. /uni25CF Axonotmesis – nerve sheath remains intact, with internal nerve fibre damage and associated Wallerian degener ation. The neural tube (endoneurium) can guide the re generating nerve fibres to their target. Good potential for recovery; nerve fibre regrowth is at 1 /uni00A0 mm per day . /uni25CF Neurotmesis – complete division of the nerve, nerve sheath and nerve fibre. Functionally poor outcome without surgi cal intervention to restore continuity of the nerve sheath. Although the Seddon classification is useful in understand ing the pathoanatomy , the critical discriminator in defining recovery , and need for possible surgical intervention, is the presence or lack of continuity of the enveloping nerve shea Peripheral nerve injury
