    摘要: An intramedullary nail for use in a medullary canal of a long bone is provided. The nail includes a body defining a longitudinal axis of the body and an external periphery of the body for fitting in the medullary canal of the long bone. The body has a first internal wall thereof defining a first opening through the body. The first opening defines a first opening centerline. The body has a second internal wall of the body defining a second opening through the body. The second opening defines a second opening centerline. The first opening centerline and the second opening centerline are oblique with respect to each other. The longitudinal axis of the body and the first opening centerline form an acute angle between the longitudinal axis of the body and the first opening centerline. The longitudinal axis of the body and the second opening centerline forming an acute angle between the longitudinal axis of the body and the second opening centerline.

    摘要: In a distal targeting system a hand-held location pad is integral with a guide section for a drill or similar surgical instrument, and has a plurality of magnetic field generators. A sensor, such as a wireless sensor, having a plurality of field transponders, is disposed in an orthopedic appliance, such as an intramedullary nail. The sensor is capable of detecting and discriminating the strength and direction of the different fields generated by the field generators. Control circuitry, preferably located in the location pad is responsive to a signal of the sensor, and determines the displacement and relative directions of an axis of the guide section, and a bore in the orthopedic appliance. A screen display and optional speaker in the location pad provide an operator-perceptible indication that enables the operator to adjust the position of the guide section so as to align its position and direction with the bore.
