A 41-year-old man presents with a history of right lower limb sciatica. Pain and numbness are reported in the sole and lateral border of the foot. The ankle reflex is absent. At which one of the following levels is the disc prolapse most likely to have occurred?
A. L2/3
B. L3/4
C. L4/5
D. L5/S1
E. S1/S2
Explanatory Notes:
Compression of the S1 nerve root accounts for the clinical features. The relation of the root to the disc is such that an L5/S1 disc prolapse most commonly compresses the S1 root in isolation as in the scenario.
