Loss of sensation in the medial anterior thigh and medial calf

In the case of femoral nerve injury, high-level injury manifests as loss of sensation in the medial femoral and medial calf. Low injury can be a simple saphenous nerve injury, showing the medial calf sensory disturbance. The femoral nerve comes from the lumbar plexus, descends along the surface of the sacroiliac muscle, penetrates the inguinal ligament and is divided into anterior and posterior strands on the outside of the lower 3-4cm femoral artery, which governs the sartorius muscle, the quadriceps femoris, and the cutaneous branch to the front of the femur and the recess. Nerves innervate the inner skin of the calf. Femoral nerve injury is rare, and most of them are surgical injuries. The main clinical manifestations after injury are quadriceps paralysis and anterior femoral and medial calf dysfunction. If it is a surgical injury, it should be repaired as soon as possible
