ABSTRACT:
Apparatus and methods for intramedullary fixation of abnormal bone, such as a femur, wherein an axially elongated intramedullary rod is provided having outwardly projecting thin fins or elongated sharp edge formations at circumferentially spaced locations spanning substantially the length of the rod to provide rotational stability, and provided with a plurality of holes in each of the surface portions between pairs of the fins or edge formations, which are normally closed by screw plugs or plugged with methylmethacrelate plugs, but which may be removed selectively prior to rod insertion into the medullary canal to permit discharge of methylmethacrelate cement or the like into desired surrounding bone areas. A coupling formation such as a threaded coupling neck is provided at one end of the rod, to be assembled with a tube extending from a piston aided dispensing device similar to a caulking gun to force the low viscosity cement into the hollow interior bore of the rod and discharge through apertures where the plugs have been removed or holes are open in the rod.
