What is the sensory for L4 nerve root?

L4 dermatome covers the medial aspect of the lower leg and the medial side of the foot. This pattern reflects how L4 nerve fibers travel to skin innervating the medial leg, over the medial malleolus, and into the medial foot and great toe region in many maps. Clinically, loss or decreased sensation in that medial leg-to-foot area points toward L4 involvement. In contrast, sensation over the lateral leg or dorsum of the foot tends to map to other roots (like L5 or S1), while the medial thigh is more typical of higher lumbar roots (L2-L3). So the sensory territory described as the medial leg and medial foot best fits the L4 distribution.
