Abstract
The metallic plates, pins and screws currently used in orthopaedics for internal fixation have elastic moduli much higher than that of the hones to which they are connected. This difference in rigidity prevents healing through proliferation of primary callus early in the healing process and in the later process of healing, bone atrophy and osteoporosis occur.
Laminate fiber-reinforced composites are the class of materials most recently probed as possible candidates for internal fracture fixation implants. The implementation of correct material choice in combination with micromechanics and lamination theory permits design of a composite laminate of desired mechanical properties for specific applications.
Using a unique molding technique, composite materials with complicated geometrical shapes such as screws, pins and plates have been obtained. These prostheses have been implanted on rabbits and some preliminary clinical results are presented.
