Abstract

A method for locating holes in orthopaedic devices, consisting of a mechanical arm (28) which is able to sweep over the plane of deformation of the orthopaedic device. A magnet (18) is rigidly attached to the orthopaedic device and a plurality of magnetic sensors (20) which are attached to the moveable rigid arm are used to sense the magnetic field strength. The outputs of the magnetic sensors as well as a position sensor (24) attached to the moveable arm are in communication with a central processing unit (22) which is able to store and process the acquired data. The central processing unit is capable of subtracting the magnetic sensor outputs, curve fitting the acquired data and indicating the position of the maximum magnetic field which corresponds to the position of the magnet. Once the position of the magnet is located, a drill template (32) connected to the mechanical arm is used to drill holes.
