Abstract
A high‐modulus polymer, polysulfone, was evaluated as a porous bone implant material. The bone ingrowth into canine cortical pellets of sintered polysulfone particles was assessed by microradiography and histology. The shear strength of the porous polysulfone–bone interface was determined by push‐out and pull‐out tests of cortical and trochanteric implants, respectively. Results indicated that the bone in‐growth into porous polysulfone specimens proceeded in such a fashion as to mimic the normal repair at the site. Mechanical testing of cortical and cancellous implants revealed that the interfacial shear strength of the porous polysulfone‐bone composite was similar to that achieved using porous metals.This publication has 12 references indexed in Scilit:
