Study Notes
Lower Limb Anatomy and Ultrasound Summary
- Lower limb is divided into gluteal, thigh, leg, and foot regions, with important transition areas at the femoral, popliteal, and ankle levels
- Pelvic bones consist of the irregularly shaped ilium, pubis, and ischium, with various bony landmarks including the iliac crest, pubic tubercle, and ischial spine
- The femur features key anatomical structures such as the head, neck, trochanters, and condyles, with the deep fascia of the thigh providing strong support and forming the iliotibial tract
- Superficial veins of the leg include the small saphenous vein on the lateral side and the great saphenous vein on the medial side, with varicose veins being a common issue in the lower limbs
- Varicose veins are dilated, elongated, and tortuous superficial veins with incompetent or absent valves, often leading to pain, leg swelling, and skin changes
- Muscles of the lower limb are categorized into anterior, posterior, and medial compartments, with distinct actions and innervations
- The anterior compartment includes the quadriceps group and sartorius, while the posterior compartment comprises the hamstring group and adductors of the thigh
- The femoral triangle is a wedge-shaped depression in the upper thigh, formed by muscles, and serves as an important anatomical landmark
- The lower limb muscles follow specific rules, with all muscles passing at least one joint and working on that joint, and different muscle groups such as prime movers, antagonists, and synergists
- Testing the quadriceps group involves applying resistance to leg extension and observing for compensatory movements or muscle recruitment
- Varicose vein treatment options include vein obliteration, support stockings, leg elevation, and exercise
- The lower limb anatomy and ultrasound information is derived from the "Gray’s Surface Anatomy and Ultrasound" and "Weir & Abrahams' Imaging Atlas of Human Anatomy" books by Elsevier Health Sciences
