✦ Synopsis

Three molecular orientation technologiesÈhydrostatic extrusion, Ðbre drawing and Ðbre compactionÈhave been used to produce a range of hydroxyapatite/polyethylene (HA/PE) bone substitute composites with sti †nesses in the range of 10 GPa to 20 GPa and strengths of up to 110 MPa, matching the mechanical properties of cortical bone. In addition, the materials have excellent ductility together with favourable bioactivity imparted by the incorporation of hydroxyapatite. These new results raise the possibility of extending the present low-load medical applications of HA/PE composites to the fabrication of skeletal implants subjected to large physiological loads, such as total hip joint replacement.

## Abstract The skeleton's response to mechanical force, or load, has significance to space travel, the treatment of osteoporosis, and orthodontic appliances. How bone senses and processes load remains largely unknown. The cellular basis of mechanotransduction, however, likely involves the integrat

The major problem with the use of porous bioceramics as bone regeneration grafts is their weak mechanical strength, which has not been overcome to date. Here we described a novel way to solve this problem. Beta-tricalcium phosphate (beta-TCP) bioceramics with a bioinspired structure were designed an

## Abstract If a bone's morphologic organization exhibits the accumulated effects of its strain history, then the relative contributions of a given strain stimulus to a bone's development may be inferred from a bone's hierarchical organization. The artiodactyl calcaneus is a short cantilever, loade
