Lower Limb

Question 1

A 52 year female post hysterectomy attends clinic. She reports pain and reduced sensation over the medial aspect of her thigh. Clinically thigh adduction is weak. What is the most likely nerve injury?

Obturator nerve
Sciatic nerve
Femoral nerve
L3 cord compression
Deep peroneal nerve

Answer 1

Obturator nerve

The obturator nerve supplies sensation to the medial aspect of the thigh and causes adduction and internal rotation of the thigh.
Injury occurs during pelvic or abdominal surgery.
L3 cord compression is unlikely.
