was changed:
The rectus femoris muscle is one of the 4four quadriceps muscles in the anterior compartment of the thigh. The others are the vastus medialis, the vastus intermedius, and the vastus lateralis.
Summary
-
origin
- straight head originates from the anterior inferior iliac spine (AIIS) of the ilium
- reflected head originates from the ilium just superior to the acetabulum
- insertion: quadriceps tendon
- action: flexes the thigh at the hip joint and extends the leg at the knee joint
- arterial supply: descending branch of the lateral circumflex femoral artery
- innervation: femoral nerve
Radiographic features
Ultrasound
Patient in a supine position in hip extension and probe placed of the AIIS in a longitudinal plane 4:
- direct head: seen directly at insertion on AIIS
- reflected head: hypoechoic appearance due to oblique course
Related pathology
Commonly injured in athletes including strains and calcified tendinopathy 4.
