Anatomy Prac Three Notes Hip Joints Ligament Iliofemoral Function • • Pubofemoral Ischiofemoral Strongest ligament in the body Prevent movement way too backward Prevent hyperextension • Weak ligament • Prevent hyperflexion and hyperextension Vascular Supply • • Retinacular arteries: - Origin: circumflex artery - Role: Artery of the head of the femur: - Origin: branch of the obturator artery - Role: Knee Joint How the knee is locked: • • • • Lower limb fully extended with the foot bearing the weight Femoral condyles rotate medially on tibial plateau and lock into place Provides a stable and weight bearing column Popliteus muscle contracts -> contraction -> lateral rotation of joint -> joint locked Bones of the pelvic grindle Articulations of ilium • • Iilosacral joint Acetabulum Articulations of Ischium • • Ischiopubic ramus Acetabulum Articulation of pubis • • Pubic symphysis Acetabulum Femur Femur articulations • • • With pelvis at the hip joint Femorotibial joint Patellofemoral joint Tibia and fibula Articulations of the tibia • • • • Femorotibial Proximal Femorotibial Distal Femorotibial Talocrural Articulations of the fibula • • • • Femorotibial Proximal Femorotibial Distal Femorotibial Talocrural Muscles of the thigh The muscles are surrounded by: • • Fascia Lata Iliotibial tract Muscles • • • • • • • • Iliac - Iliacs + psoas major -> iliopsoas - Joints crossed: lesser trochanter - Action: thigh flexion Gluteal - Superficial: thigh extension - Deep: lateral thigh rotation Anterior - Knee extension Posterior thigh - Knee flexion Medial thigh - Adduct the thigh at the hip joint Anterior leg - Dorsiflexion and toe extension Lateral leg - Foot eversion Posterior leg - Superficial: plantarflexion - Deep: toe flexion and toe inversion Innervation • • • • • Femoral - L2-L4: from posterior division of the lumbar plexus - Anterior thigh Obturator - L2-L4: from anterior division of the lumbar plexus - Medial thigh Siatic - L4 – S3 - Posterior thigh Fibular - L4 – S2 - Superficial: lateral leg - Deep: anterior leg Tibial - L4 – S3 - Posterior thigh Blood supply Thigh • • • Leg Anterior: femoral Medial: obturator Posterior: deep femoral • • • Anterior: deep fibular nerve Lateral: fibular Posterior: posterior tibial artery
