摘要：
A vertebral body replacement device (5000) includes a body member (5100) and a central rod member (5200) having two threaded portions and configured to be operatively associated with the body member (5100). The device also includes a first end member (5300) and a second end member (5400) with the end members configured to threadingly engage the threaded portions of the central rod member (5200). The body member (5100) and the two end members (5300,5400) are further constructed to inhibit rotational movement of the two end members when the device is positioned within a space within a spine as the two end members will engage the adjacent respective vertebral bodies following rotational actuation of the central rod member (5200) causing the end members (5300,5400) to move in an axial direction relative to the body member (5100), thereby allowing the two end members to apply a force to the two vertebral bodies. A surgical instrument and method for using the device are also disclosed.
