To differentiate between a femoral nerve lesion and an L2/3/4 root (or plexus) lesion, which muscle should you test?

A: Quadriceps

B: Hamstrings

C: Gluteus maximus

D: Hip adductors

The hip adductors are supplied by L2/3/4 but via the obturator nerve. Testing their function helps distinguish between femoral nerve and L2/3/4 root lesions.
