A new concept of fixation using extra-cortical plated prostheses suitable for bone replacements was investigated. The plates were coated with hydroxyapatite and were investigated using radiography, backscattered scanning electron microscopy and histological techniques. Image analysis was used to evaluate bone porosity and remodelling around the prosthesis, and bone upgrowth onto the plates. It was shown that bone appears to surround the plates and provides enhanced fixation. The plates seemed to become integrated into the load-bearing structure of the cortex. The new fixation method merits further investigation.
