Neurotmesis är en kränkning av integriteten hos alla anatomiska komponenter i när nervfibrerna sönderbrott (axonotmesis); Förlust av nervfunktionen kan vara grav och återhämtning osannolikt när nerven är helt avskild (neurotmesis). Axonotmesis: Skada som orsakas av att en nerv sträckts eller klämts och nervtrådarna har gått av.

The peripheral nerve is made up of axons and Schwann cells. It can have an outer insulating layer (myelinated type) or lack this insulation (unmyelinated type). The Schwann cells form a sheath over each axon in myelinated nerves and in the unmyelinated nerves Schwann cell-sheath covers a group of axons.

The clinical history and examination are paramount in assessing the extent and severity of nerve injury. Nerve injuries are generally divided into three categories as neuropraxia, axonotmesis and neurotmesis. Neurotmesis is the most severe form. Schwann cells are activated within 24 hours of the injury and the healing cascade continued with the cells, which are stimulated by Schwann cells.

In axonotmesis, as well as in neurotmesis, a sequence of pathological events known as wallerian degeneration occurs in the nerve segment distal to the injury. This process includes fragmentation and degeneration of the axon distal to the lesion and phagocytosis of the myelin sheath by Schwann cells and macrophages neurropraxia.
