Ruptured disc at L4-L5 affecting the L5nerve root. Disc herniation at L3-L4

Positive femoral stretch test: the test is positive if the pain is felt in the ipsilateral anterior thigh.
Disc herniation at L4-L5
•Clinical evaluation of L5 nerve root: sensory: L5 dorsum of foot and leg. L5 extension of the toe.
