Nerve Injury Classification

In 1951 Sir Sydney Sunderland further stratified the three nerve injury types described by Seddon into five categories according to Wallerian axon degeneration and disruption of the endoneurial perineurial and epineurial tissues again based upon histological findings 14. 10 rivi 24 Nerve Injury Classification via Independent Classification.

The first was published by Seddon in 1943 and separated injuries into three categories neuropraxia axonotmesis and neurotmesis largely based on the scale of injury from microscopic to macroscopic. Recovery occurs within a few days to 3 months. This includes for example the ki-netic energy of the patient moving at high speed into a car or wall a bullet moving through tissue with a.

The clinical history and examination are paramount in assessing the extent and severity of nerve injury. Seddons classification of nerve injuries into three categories neurapraxia axonotmesis and neurotmesis provides a basis for assessment prognosis and management. OrthoFixar Basic Science.

Nerve injury can result from compression gun shoot stapping injuries or iatrogenic injuries. This requires surgical adaptation and co-aptation. January 9 2021 By.

CLASSIFICATION OF NERVE INJURIES For the purposes of this article trauma is defined as injury resulting from kinetic energy applied to the nerve or limb. Peripheral nerve injuries encompass a range of reversible and irreversible impairments determined by injury level axonal disruption and time to treatment. There are two classification schema used to describe nerve injuries.

It could be due to laceration avulsion or chemical injury. Br Med J 19422237. Some basic anatomy along with the two classification systems and their corresponding EMG findings need to be learned and remembered.

The mildest form of injury is called neurapraxia defined by focal demyelination without damage to the axons or the connective tissues.

SEDDON CLASSIFICATION The foundation of our current understanding of the classification of nerve injuries was laid down by Seddon who was the Nuffield Professor of Orthopaedics after studying some 460 nerve cases in Oxford. Investigations including neurophysiology testing and imaging with MRI or ultrasound may give extra diagnostic information. Br Med J 1942.

Intraosseous fifth degree injury may undergo spontaneous recovery of some degree if the canal is intact. Understanding nerve injury classification is essential for prognostic value clinically. Classification of Nerve Injuries.

Diagnosis can be made based on clinical examination and confirmed with EMGNCS. Seddon was the first to classify nerve injuries into three categories based on the presence of demyelination and the extent of damage to the axons and the connective tissues of the nerve 6. There is increased T2STIR signal in the nerve however the muscle appears normal.
