Intramedullary devices have been used since 1989 for fractures around the trochanter. Standard PFN has been shown to be one of the stable and successful intramedullary devices for pertrochanteric fractures. In order to minimise the intra-operative complications, small PFN has been designed to fit the Asian femora. Before performing a clinical documentation series, the authors with the computer assisstance performed virtual templating of 60 asian femora. After standardising the magnification of the radiograph with that of the template, best possible fit of the latter was achevied. Various parameters such as:
Width of the remaining neck from the surface of femoral neck screw and hip pin. Height of the proximal end of the nail from the tip of greater trochanter. The distance between the actual and proposed take-off point of medio-lateral angulation. Width of intramedullary canal at distal end of the nail were measured. After analysis of the measurements, we propose to further modify the small PFN in order to get best fit and minimal intra-operative complications.
