Targeting surgical instrument for use in spinal disc replacement and methods for use in spinal disc replacement

Abstract

A targeting surgical instrument for use in spinal disc replacement includes a first arm, a second arm and a body portion. The first arm is configured to be longitudinally aligned with a mid-line of a spine and to be at least partially received on an endplate of a lower vertebra of spinal cavity. The spinal cavity is defined by a lower vertebra and an upper vertebra of the spinal cavity. The second arm is positioned at an angle relative to the first arm. The second arm defines an insertion angle for a spinal implant. The body portion connects the first arm and the second arm. The body portion includes a plurality of radial opaque markers located to allow alignment of the first arm on the mid-line of the spine.

Dependencies are inferred from the claim text.
