Traumatic Nerve Injury
Our understanding of nerves and nerve injuries (NIs) has traditionally been based on war experiences. While caring for the injured during Wartime (1942), Sir Herbert Seddon created his NI classification system. However, it is not rare to find NI in non-combat-related trauma cases in recent times. These injuries have the ability to change one's life and are frequently accompanied with considerable morbidity, which can lead to significant disabilities. Because they most commonly affect young adults of working age, these disabilities have long-term consequences for the patients.
The peripheral nerve trunk is made up of three layers that enclose nerve fibers. To provide physical and metabolic stability, the innermost collagenous endoneurium layer encases the axonal fibers (myelinated or unmyelinated). The nerve fascicles are made up of these cells, which are bordered by a flattened cellular layer termed the perineurium. The fascicles are surrounded by the epineurium, the outermost collagenous layer. Understanding the classifications, clinical symptoms, and prognosis of NIs, as well as the best optimal care for each patient, requires knowledge of anatomy.
