HIP JOINT-FEMORAL HEAD & NECK

SUMMARY

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.
