Abstract: Surgical apparatus for use in guiding and aligning a surgical blade or osteotome for bone removal from the tibia and femur during a proximal tibia osteotomy or a total knee replacement operation is disclosed. The apparatus includes a femur "T" bar unit and a tibia "T" bar unit which are connected to the shaft of the femur and tibia bones respectively. First and second guide members provide means such that desired or selected cutting planes can be maintained during the bone cutting operation. These guides may be selectively attached to the mid portion of the T-bar units for providing a guide for total knee replacement or to the lateral or medial ends of the "T"-bar for a proximal tibia osteotomy. The medial and lateral ends of the cross bars of the T-bar units are secured to each other by means which are selected according to the operation to be performed. That is, a selection is made depending on whether the operation is to be a proximal tibia osteotomy or a total knee replacement.

Abstract: A quadrilateral or thigh brim suitable for use as a socket brim for an amputee or with a cast brace for patients with a leg fracture is disclosed. The brim is molded as a sleeve having a modified rectangular cross-section which substantially conforms to the cross-section of a human thigh and is made of a resilient material such as a polyethelene foam material in such a manner that it provides both cushioning and a semirigid structure. The sleeve further includes contact surfaces which are rolled or tear drop shaped edges around the top area which will contact the buttocks and groin area to reduce and eliminate irritations due to chaffing, etc. In use, the brim size is selected such that it can be moved up over the leg into a slightly snug fit which will not interfere with blood circulation.
