intervertebral dis hernation where nerve associaed with the inferior vertebral body id impinged ie L3/4 impinges the L4 spinal nerve

Question 33

describe the phys of intervertebral disc herniation

Answer 33

generally herniate posterolaterally due to think posterior longitudinal ligmanet and thicker anterior longitudinal ligmanet along the midline of vertebral bodies
