HNP LUMBALIS

Abstract

Lumbar herniated nucleus pulposus (HNP) is a disorder characterized by local displacement of the disc beyond the anatomical boundaries of the intervertebral space causing pain, weakness or numbness, and/or tingling in myotomal or dermatomal distribution. HNP is the most common cause of low back pain. Lumbar HNP itself has several underlying etiologies, such as old age, excessive axial load, connective tissue disorders, and congenital abnormalities. Management of HNP can be carried out non-operatively or operatively, depending on the severity, the symptoms that arise, and the response to non-operative treatment.
