Summary
Reaming bone to implant prosthetics triggers periosteal angiogenesis, increasing blood vessel density. Poorly integrating implant materials stimulate greater periosteal vascularity compared to those that osseointegrate.
Area of Science:
- Orthopedic surgery
- Biomaterials science
- Vascular biology
Context:
- Endosteal vasculature destruction during reaming.
- Periosteal microvascular response to surgical trauma.
- Comparison of implant materials in endoprosthetics.
Purpose:
- Characterize periosteal microvascular reaction post-reaming.
- Monitor the time course of vascular changes.
- Compare microcirculatory effects of titanium, steel-alloy, and polyethylene implants.
Summary:
- Reaming alone increased vascular and capillary density in rat tibias.
- All implant materials increased anteromedial vascular density.
- Polyethylene implants significantly increased anterolateral vascular and capillary density, but failed to osseointegrate.
Impact:
- Periosteal angiogenesis is enhanced 12 weeks post-reaming.
- Compensatory microvascular reactions are material-independent if osseointegration occurs.
- Poorly osseointegrating materials induce significant periosteal microvascular density increases.

01:29Blood and Nerve Supply to the Bones
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
