Posterior Femoral Cutaneous Nerve, Posterior View

Description

Running superficially along the posterior thigh, the posterior femoral cutaneous nerve is traced from its proximal origin near the pelvis, descending inferiorly toward the popliteal fossa. A posterior view places it posterior to the femur and knee joint, with the tibia medial and the fibula lateral in the leg below. Portions of the pelvic bone, femur, tibia, fibula, and the bones of the foot provide bony landmarks for the nerve’s long cutaneous course. The sciatic nerve is also visible deeper and more proximal, emphasizing the posterior compartment relationships. Clinically, this is the nerve that explains isolated posterior thigh sensory symptoms when motor exam and reflexes remain intact. Entrapment or irritation can occur in the deep gluteal region, including around the ischial tuberosity, or be affected by iatrogenic injury during posterior hip approaches, hamstring surgery, or injections placed too medially and inferiorly. Clear separation from the larger sciatic nerve matters when teaching the difference between posterior thigh cutaneous pain and true sciatic neuropathy or L5 to S1 radiculopathy. Sensory only. Use this artwork in gross anatomy lab manuals, neuroanatomy and peripheral nerve lectures, and clinical education materials for sports medicine, orthopaedics, pain medicine, or regional anesthesia where posterior thigh innervation and the popliteal fossa landmarks must be communicated quickly.
