摘要: A spacer-insertion instrument for delivering a spacer to a spine is disclosed. The instrument includes a handle portion and a guide coupled to the handle portion. The instrument further includes a shaft coupled to the handle portion and extending along the guide. The instrument further includes a tip including an attachment end portion coupled to the shaft and opposing fingers movable relative to one another and adapted to grasp the spacer when the shaft is moved to actuate the fingers. The handle portion includes a grip and a trigger coupled to the grip and to the shaft and movement of the trigger toward the grip causes the fingers to move toward one another. A method for delivering a vertebral body spacer to a disc space formed in a spine between adjacent vertebral bodies is also disclosed.

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: An implant may provide a body capable of being fit in an intervertebral space and a spin-plate rotatable with respect to the body. The spin-plate may a blade. The blade may possess grooves in its flat faces, or may be provided with an overhang. The path of the overhang or groove may be such that as the spin-plate advances in its rotation, a vertebra engaged with the blade is drawn toward the body of the implant. Pins may be placed in adjacent vertebrae such as to engage the spin-plate. Surgical methods are also described.

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.
