Document Summary
Flexor (external rotation of hip) or trunk flexion. Inserts into the iliotibial tract (with gluteus max) and inserts onto gerdys. Like a ligament, from pelvis to tibia: specialized portion of fascia latae, supports and braces lateral side of the knee, resists varus forces, compresses mm compartment of thigh and indoing so assists venous return. Small external rotators, all supplied by small branches of lumbar plexus. Muscles of the thigh: 3 main compartments, anterior (quads and sartorius) flexion of hip and extension of knee, medial (adductors) hip adductors, posterior (hamstrings) extension of hip and flexion of knee. Anterior compartment of the thigh (hip flexors + knee extensors) Medial compartment muscles adductors, all insert around linea aspera except gracilis (to pes anserenis below the knee) All supplied by obturator nerve l2-4 except for pectineus. Posterior compartment of the thigh hip extensors and knee flexors. All ischial tuberosity except short head biceps. Short head linea aspera + lateral supracondylar line.
