Spinal spacing implants, spinal spacer assembly, expander and insertion instruments, kits and methods of assembly and use are disclosed. The spinal implant replacement instrument kit including a distraction instrument, a spacer inserter, and a spinal implant. A distraction instrument includes a first inserter member, a second inserter member, a first arm coupled to the first inserter member, a second arm coupled to the second inserter member, a distraction system coupled to the first arm and second arm, a first handle coupled to the first arm and the distraction system, and a second handle coupled to the second arm and the distraction system. Spinal spacing implants, spinal spacer assemblies, and methods of assembling and using the implants assemblies, and instruments are also disclosed.

A vertebral body replacement device includes a first member and a first footplate detachably connectable to the first member, a second member and a second footplate detachably connectable to the second member, and a central member detachably connectable to the first member. The first member is displaceable relative to the second member in response to rotation of the central member relative to the first member to adjust the length of the vertebral body replacement device. The first footplate includes a first surface oriented toward the first member, a second surface oriented away from the first member, and a sidewall extending between the first surface and the second surface. The first surface includes an alignment slot facing the first member. The alignment slot is open through the sidewall of the first footplate and configured to slidingly engage the first member to orient the first footplate relative to the first member.

Vertebral body replacement device and method for use to maintain a space between two vertebral bodies within a spine

A vertebral body replacement device includes a first member and a first footplate detachably connectable to the first member, a second member and a second footplate detachably connectable to the second member, and a central member detachably connectable to the first member. The first member is axially displaceable relative to the second member in response to rotation of the central member relative to the first member to adjust the length of the vertebral body replacement device. The first member includes a pair of first fastener holes and a pair of second fastener holes angularly offset from the first fastener holes. The first footplate includes an aperture configured to align with one of the first fastener holes to orient the footplate in a first position or one of the second fastener holes to orient the footplate in a second position.

A vertebral body replacement device includes a body member and a central rod member having two threaded portions and configured to be operatively associated with the body member. The device also includes a first end member and a second end member with the end members configured to threadingly engage the threaded portions of the central rod member. The body member and the two end members 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 causing the end members to move in an axial direction relative to the body member, 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.
