Distraction Implantation. A New Technique in Total Joint Arthroplasty and Direct Skeletal Attachment.

ABSTRACT:

Background

Using the marrow canal of a tubular bone as a holding compartment for implant stems has been the paradigm in total joint arthroplasty for more than a century, and for direct skeletal attachment of limb prostheses for about forty years. Both interventions rely on the osteogenesis in the inner walls of the marrow canal in a direction radially inwards. It so remains despite the frequent aseptic loosening of the implant stems caused by the resorption of the marrow canal's inner walls which increases the canal's diameter and reduces its capacity to hold the implant.

Materials and methods

To improve the bone-device bond, we suggest an implantation methodology that activates positive osteogenic remodeling in the circular direction rather than radially inwards. The ration
