Ligament of the Head of the Femur (Ligamentum Teres)
Ligamentum capitis femoris
- Origin
- Fovea capitis femoris
- Insertion
- Acetabular fossa and transverse acetabular ligament of the pelvis
- Function
- In children carries a branch of the obturator artery (artery of the ligamentum teres) that contributes to the blood supply of the femoral head; of limited mechanical importance in adults
- Innervation
- Occasionally contains free sensory nerve endings
- Movement & chain
- Guides femoral head congruence within the acetabular socket and tightens during hip adduction, flexion, and external rotation.
- Palpation
- Intra-articular ligament between fovea capitis femoris and acetabular notch; cannot be palpated.
- Clinical
- Carries the acetabular artery to the femoral head (critical in pediatric vascularization); tears in traumatic hip dislocation and femoroacetabular impingement (FAI).
- Segmental innervation
- L2–L4 (obturator nerve)
- In clinical practice
- Skin and pressure point inspection; maintain comfortable positioning and proper body mechanics during patient handling and daily care.
