Hip fracture represents a major health problem facing elderly people. Hip prosthesis is the greatest challenge of biomaterial design to meet the needs of joint arthroplasty. The loads experienced by the lower limbs are very severe; in the femur they can be several folds higher than the body weight. Unusual combinations of mechanical, chemical, and physical properties are required by hip prostheses. High strength and toughness, long-life resistance, tailored stiffness, resistance to impact, abrasion and corrosion, adequate transparency to electromagnetic waves for diagnostic purposes, are the combination of properties relevant for tissue substitute design. Composite hip prostheses, that is, continuous fibre-reinforced polymers, have gained an increasingly important role in the development of prosthetic devices.

Abstract
Hip fracture represents a major health problem facing elderly people. Hip prosthesis is the greatest challenge of biomaterial design to meet the needs of joint arthroplasty. The loads experienced by the lower limbs are very severe; in the femur they can be several folds higher than the body weight. Unusual combinations of mechanical, chemical, and physical properties are required by hip prostheses. High strength and toughness, long-life resistance, tailored stiffness, resistance to impact, abrasion and corrosion, adequate transparency to electromagnetic waves for diagnostic purposes, are the combination of properties relevant for tissue substitute design. Composite hip prostheses, that is, continuous fibre-reinforced polymers, have gained an increasingly important role in the development of prosthetic devices.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
