The Evaluation Of Polysulfone Composites As Structural Implants In Orthopaedic Surgery, Howard L. Scalzo

Theses

Two polysulfone composites were evaluated to determine their use as structural implants in orthopaedic surgery. The first composite, carbon fiber reinforced polysulfone (C/PS), was evaluated for environmental degradation in an in vivo and in vitro study. The C/PS composites were implanted subcutaneously in the abdomen of rabbits for the in vivo study and immersed in saline solution at 32° C for the in vitro study. The second composite, hydroxylapatite coated polysulfone (HA/PS), was evaluated for bone ingrowth in an in vivo study, and for attachment strength between the HA and the PS in an in vitro study. Also, two surface …
