Corpus: Ligament of femoral head
from Latin: ligamentum - ligament; capus - head; femur - thigh
1. Definition
The ligament of the femoral head is a thin, triangular ligament that runs through the joint capsule inside the hip joint.
2. Anatomy
The two branches of the ligament of the femoral head originate at the lower edge of the acetabular fossa, where they interweave with the fibers of the transverse acetabular ligament, which traverses the acetabular notch. The ligament extends through the joint cavity to the anterosuperior section of the fovea capitis femoris. It contains a thin branch of the obturator artery, known as the artery of the ligament of the head of the femur. This artery is involved in supplying blood to the femur, particularly in children, and is thought to have a proprioceptive function. The fatty and connective tissue surrounding the fiber bundles is also known as the "pulvinar."
3. Clinic
The ligament of the femoral head can tear in the event of fractures of the femoral head or neck.
