Introduction The musculature of the anterior femur is called the quadriceps musculature.
The musculature of the anterior femur is called the quadriceps musculature. It is made up of the rectus femoris , vastus medialis , vastus intermedius , and vastus lateralis. These muscles all come together within the distal portion of the femur to make up the quadriceps tendon.
The rectus femoris is unique, as it has two heads and thus two different tendon origins. The straight head arises from anterior superior iliac spine and the indirect head arises from the superior acetabular ridge. Anatomy of the rectus femoris with two origins of insertion The quadriceps muscle aids in extension of the knee, hip flexion, and pelvis stabilization.
Injuries in this area can include avulsions, strains, musculature tears, myotendinous junction tears, and tissue calcification. An injury to the quadriceps muscle has been found to be more common in football, soccer, and other sprinting sports. In a study looking at English Premier League lower extremity muscle injuries, rectus femoris strains accounted for 29% of all injuries.
Diagnosis Diagnosis is typically made clinically. A patient will complain of an acute tear in the anterior thigh. However, some patients have more gradual and subacute injury and will complain of pain with running and kicking.
Physical exam will evaluate for any evidence of muscle retraction and ecchymosis to the anterior thigh. A bulge can also be seen in certain injury patterns. Patients will typically have pain with resisted knee extension and pain to palpation over the quadricep musculature.
If you are experiencing symptoms that may be related to review on quadriceps strains, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
