Study Notes
- The primary hip flexor muscles are the iliopsoas, sartorius, tensor fasciae latae, rectus femoris, adductor longus, and pectineus.
- Secondary hip flexors include the adductor brevis, gracilis, and anterior fibers of the gluteus minimus.
- The iliopsoas consists of two muscles: the iliacus and the psoas major.
- The psoas major contributes to frontal plane stability to the lumbar spine.
- The psoas minor may stabilize the position of the underlying iliopsoas as it crosses the hip and anterior brim of the pelvis.
- The sartorius muscle courses distally and medially across the thigh to attach on the medial surface of the proximal tibia.
- The tensor fasciae latae is a primary flexor and abductor of the hip.
- The fascia lata of the thigh turns inward between muscles, forming distinct fascial sheets known as intermuscular septa.
- The intermuscular septa of the thigh ultimately attach to the linea aspera on the posterior surface of the femur.
- Activation of the tensor fasciae latae can transmit a force around the thigh and between muscle groups.
- The tensor fascia lata is a muscle of the hip that attaches inferiorly through the iliotibial band.
- Repetitive tension within the iliotibial band may cause inflammation near the lateral tubercle of the tibia.
- Stretching maneuvers for a tightened tensor fascia lata are often performed with the knee extended and hip adduction and extension.
- The proximal part of the rectus femoris emerges between the sartorius and tensor fasciae latae.
- The rectus femoris has proximal attachments on the anterior-inferior iliac spine, superior rim of the acetabulum, and adjacent joint capsule.
- The reflected tendon of the rectus femoris is an important stabilizer of the anterior capsule.
- The rectus femoris attaches to the tibia via the patellar tendon and is responsible for one-third of the total isometric flexion torque at the hip.
- The rectus femoris is a primary knee extensor.
- The rectus femoris is a large bipennate-shaped muscle.
- The pectineus and adductor longus are described in the section on the adductors of the hip.
