Trueta and Harrison describe the complete intra-osseous vascular anatomy of the adult human femoral head using injection techniques on 36 cadaveric specimens aged 20–100. The study was undertaken as control material for research into osteoarthritis-related vascular changes. It details named arterial groups, their territorial contributions, bone marrow microvascular architecture, and the subchondral capillary system at the cartilage interface.
When you debate fixation versus arthroplasty for a displaced femoral neck fracture, Trueta's anatomy is the foundation of that decision.
The lateral epiphysial arteries enter the femoral head superiorly and postero-superiorly, in a thick fibrous sheath, right at the site of maximum disruption in adduction-type fractures. This is why unimpacted adduction fractures carry far higher AVN rates than abduction fractures, and it informs the threshold for choosing arthroplasty over fixation in displaced femoral neck fractures — particularly in older patients where the AVN consequence is severe.
Trueta also established that the real risk factor for femoral head osteonecrosis is mechanical disruption of these vessels, not age-related vascular decline. Vascularity is preserved into the tenth decade; what changes is the fracture's ability to tear the postero-superior retinacular vessels.
The subchondral capillary loop system described here later shaped thinking about cartilage nutrition and the pathological significance of subchondral bone integrity in osteoarthritis. A connection the authors themselves flagged as a subject for follow-up work.
