Abstract: A targeting device for use in hip surgery and more particularly for use in hip replacement surgery or hip resurfacing surgery, which may include minimally invasive surgery. An exemplary embodiment of the targeting device comprises one or more sensor devices, a guide sleeve, a guide sleeve location adjustor, and a computer device with software for receiving data from the sensor device or devices and processing this data so as to determine the location of the centerline of the femoral neck. In other embodiments, the sensor devices are movable so as to obtain data at two or more different radial locations around the femoral neck or angularly spaced in order to obtain data in the anterior-posterior plane and in the superior-inferior plane. Moreover, the sensor devices can be placed on retractable arms.
