Neurotmesis
Neurotmesis (pronunciation: /nʊərɒt'miːsɪs/) is a term used in medicine to describe the most severe form of nerve injury. It is derived from the Greek words "neuro" meaning nerve and "tmesis" meaning cutting.
Definition
Neurotmesis refers to the complete severance or disruption of a nerve. This type of nerve injury is characterized by the loss of both motor and sensory function in the affected area. Unlike other forms of nerve injury, such as axonotmesis and neurapraxia, neurotmesis often results in permanent damage.
Causes
Neurotmesis is typically caused by severe trauma, such as a deep cut or crush injury. It can also occur as a result of certain medical procedures, such as surgery, if a nerve is accidentally severed.
Symptoms
The symptoms of neurotmesis can vary depending on the specific nerve that is damaged. However, common symptoms include loss of sensation, muscle weakness, and paralysis in the affected area.
Treatment
Treatment for neurotmesis often involves surgery to repair the damaged nerve. However, the success of such treatments can vary and in many cases, full recovery is not possible.
