    • Gluteal Fold: A crease in the skin at the juncture of the buttock and thigh.
    • Popliteal Fossa: A depression behind the knee.
    • Iliotibial Tract: A fibrous band that runs along the lateral thigh.
    • Sole of Foot: The bottom surface of the foot.

    Pelvic Girdle Bones

    • Coxal Bone (Hip Bone): Composed of the ilium, ischium, and pubis.
    • Ilium: The largest portion of the coxal bone.
    • Ischium: Posterior portion of the coxal bone.
    • Pubis: Anterior portion of the coxal bone.
    • Sacrum: A triangular bone forming part of the posterior pelvis.
    • Coccyx: Tailbone, small triangular bone.
    • Pelvic Brim: The opening boundary of the true pelvis.
    • Acetabulum: The socket where the femur connects to the hip.
    • Iliac Fossa: A depression on the ilium.
    • Iliac Crest: The superior margin of the ilium.
    • Sacroiliac Joint: Joint where the sacrum meets the ilium.
    • Pubic Symphysis: Joint where the two pubic bones meet.
    • Pubic Tubercle: A bony prominence on the pubis.
    • Sacral Promontory: The anterior superior aspect of the sacrum.
    • Anterior Superior Iliac Spine: A bony landmark on the ilium.
    • Anterior Inferior Iliac Spine: Another bony landmark on the ilium.

    Hip Joint

    • Iliofemoral Ligament - Anterior: Reinforces the anterior aspect of the joint capsule.

    • Pubofemoral Ligament - Anterior: Reinforces the inferior aspect of the joint capsule.

    • Ischiofemoral Ligament - Posterolateral: Reinforces the posterolateral aspect of the joint capsule.

    • Ligament of the Head of the Femur/Ligamentum Teres: A small ligament within the hip joint.

    • Capsular Ligament: The joint capsule surrounding the hip joint.

    • Arteries of the Lower Limb and Pelvis: Diagrams show the main arterial supply branches of the aorta and pelvis to the lower limbs.

    • Veins of the Lower Limb and Pelvis: Diagrams show the main venous drainage of the lower limbs and the pelvic region.

    Hip and Thigh Pathologies

    • Angle of Inclination (Coxa Vara/Normal/Coxa Valga): Abnormal angles can lead to stress on the hip joint and gait irregularities.

    • Vitamin D/Calcium Deficiency (Rickets/Osteomalacia): Bone diseases affecting children (Rickets) and adults (Osteomalacia).

    • Hip Fracture (due to Osteoporosis): Common in elderly individuals due to bone density loss.

    • Common Hip Fractures: Different types of hip fractures, including intertrochanteric, comminuted, reverse obliquity, subcapital neck, transcervical neck, displaced, and femoral head fractures.

    • Other Knee and Lower Limb Fractures: Illustrates different types and classifications of fractures of other lower limb bones and the knee joint.

    • Congenital Dislocation of the Hip: Defect common in female infants, resulting in an incomplete acetabulum or loose hip ligaments.

    Lower Limb Anatomy (Nerves):

    • Lumbosacral Plexus: A network of nerves that supply the lower limb.
    • Nerves of the lumbar plexus: Diagrams show the different nerves branching out, with labels and anatomical locations.
    • Nerves of the sacral plexus: Diagrams show the different nerves for the sacral plexus, including anatomical areas supplied.

    Thigh Muscles (Anterior):

    • The muscles of the anterior compartment of the thigh are primarily extensors of the leg at the knee and secondarily flexors of the thigh at the hip.
    • They are innervated by the femoral nerve.
    • The femoral artery supplies these muscles.

    Thigh Muscles (Medial)

    • The muscles of the medial compartment of the thigh are primarily adductors of the thigh.
    • Most are innervated by the obturator nerve.
    • The obturator and deep femoral arteries supply blood.

    Muscles of the Leg (Posterior):

    • These muscles consist primarily of extensors of the thigh, with medial and lateral rotation and abduction being possible.
    • Gluteus medius is a common injection site.

    Posterior Thigh Muscles:

    • The hamstring muscles (biceps femoris, semitendinosus, semimembranosus, and adductor magnus) primarily are flexors of the knee.
    • They are innervated by the tibial branch of the sciatic nerve.

    Special Regions:

    • Hunter's Canal: A structure with the femoral artery and vein, important for procedures/injections. Clinical significance includes sensory anesthesia for procedures, and using landmarks to locate the saphenous nerve

    Popliteal Fossa:

    • Posterior muscles of the lower leg (gastrocsnemius, semitendinosus etc) form the popliteal fossa.

    • Popliteal artery and vein: major vessels in this region supplying the muscles and underlying structures of the back of the knee.

    • Subtalar Joint (Talocalcaneal Joint): Between the talus and calcaneus; facilitates inversion and eversion movement.
    • Intertarsal Joints: Varied joints between the tarsal bones.
    • Tarsometatarsal Joints (Lisfranc Joint): Joints between the tarsals and metatarsals crucial for the proper foot structure.
    • Metatarsophalangeal (MTP) Joints: Joints between metatarsals and the bases of the phalanges.
    • Interphalangeal (IP) Joints (toe joints): Articulations between the phalanges.

    Ankle and Foot Ligaments:

    • Medial (Deltoid) Ligament: Reinforces the medial side of the ankle joint.
    • Lateral Ligaments: (anterior talofibular, calcaneofibular, posterior talofibular) Reinforce the lateral side of the talocrural joint.
