  • Thigh Three Compartments; ant., medial and posterior Lateral thigh consists of thickened fascia of the lower extremity called the Fascia Latae called the Iliotibial Band (Tract) that serves as an insertion of the Tensor Fascia Latae muscle Extends distal and lateral to knee, inserts on the tibia at Gerdys Tubercle

  • Thigh Anterior compartment = knee extensors and some hip flexors; innervated by femoral nerve, blood supply by femoral artery and its branches Medial Compartment = hip adductors (some rotation and flexion); innervated by obturator nerve and its branch, blood supply by branches off deep femoral artery and obturator artery Posterior compartment = hip extensors and knee flexors; innervated by tibial or common peroneal nerves, blood supply by deep femoral artery
