Abstract: The present invention provides a collar containing a novel gel formulation of a wax and linear aliphatic hydrocarbon combination capable of the controlled release of an insecticide such as chlorpyrifos for the control of arthropods infesting animals. FIG. 1 depicts release rate proportional to chlorpyrifos (DURSBAN) concentration.
Abstract: A method and apparatus for preparing a planar surface on the distal femur prior to implantation of a femoral knee prosthesis has a femoral plate with an opening therein for exposing both condyles of the femur. A guide with a central aperture is used to align the femoral plate on the distal femur. The guide is releasably secured to the femoral plate and an intramedullary guide rod is placed through the aperture therein and into the intramedullary canal of the femur. After alignment with the intramedullary canal, the femoral plate is pinned to the femur and the rod and guide are removed. A milling guide having two bores, one adjacent each condyle, is then placed on the femoral plate and an end mill is used to mill a planar surface on at least one of the condyles.
