HIP JOINT-FEMORAL HEAD & NECK

1. The non-articulating convexity of the head is excavated into a pit (the fovea) for attachment of the ligamentum teres.
2. The other end of the ligamentum teres is attached to the transverse ligament.
3. The fibrous capsule is strengthened by 3 ligaments - ilio-femoral, ischio-femoral ( weakest ligament) , pubo-femoral.
4. These ligaments are 'unwound' if the femur is flexed + externally rotated.
5. Blood supply - nutrient arteries from the trochanteric anastamosis which travel along the NOF, under the retinacular fibres + artery within the ligamentum teres (usually atrophied by age 7).
6. Nerve supply - branches of the femoral n. + sciatic n. + obturator n.
