BONE-BLOOD SUPPLY

Anatomy-General

BONE-BLOOD SUPPLY

1. Both cancellous and compact bones are supplied by blood vessels from the periosteum.

2. Before union with the shaft, the epiphysis is supplied by the circulus vasculosus of the joint.

3. Circulus vasculosus - vascular plexus which supplies the joint and synovial membrane, lying between the capsule and synovial membrane at their attachment to the epiphyseal line.

4. The ends of the bone shaft in contact with the epiphysis is the metaphysis.

5. In children this contains terminal end-arteries and is subject to embolism and infarction. The vessels of the circulus vasculosus do not contact vessels of the shaft until ossification of the epiphysis.
