Use of a custom retrograde intramedullary rod for the management of distal femoral nonunion: a report of two cases.

Nonunion of the distal femur is a rare injury that is difficult to manage. A variety of surgical implants and techniques are available. We present an alternative mode of treatment for supracondylar femoral nonunion using a custom retrograde titanium femoral nail (Biomet; Warsaw, IN) to successfully achieve union in two cases. We believe the added length, custom modifications, and enhanced stability allowed better fixation in an osteopenic distal femur.
