Tucker's 1949 cadaveric study of 44 femora (24 children, 20 adults) uses barium injection, Spalteholz clarification, and histological sectioning to map the three arterial systems supplying the upper femur and determine their relative contributions across age groups.
Understanding that retinacular vessels provide the primary blood supply to the femoral head explains why capsular damage or increased intracapsular pressure can lead to avascular necrosis.
The limited contribution of the foveolar artery, especially in children, helps explain the vulnerability of the pediatric femoral head to ischemic injury.
