Abstract
Abstract An orthopaedic reconstruction plate (10) designed to be secured to the femur to contain bone graft material placed in the area of the lesser trochanter includes a series of pins extending from the inner surface facing the bone to prevent excessive compressive forces from being imparted to the bone. The plate may have a series of perforations to enhance the flow of blood to the bone. The plate may also include a plurality of sections and an area of reduced thickness between said sections in order to be bendable.
