Expandable spinal interbody implants include a body and at least one extendable support element connected thereto. Such an implant may include a second extendable support element and a tool selectively positionable with respect to the implant so as to independently or simultaneously expand both extendable support elements. In another example, such an implant may include, at each of a first and second location, a respective movable member and a respective locking element. The at least one extendable support element may be actuatable to expand so as to induce movement of at least one of the movable members away from the body. The locking elements at each of the first and second locations may be selectively lockable such that, when locked, the locking element restrains movement of the associated movable member at that location away from the body without restraining movement of the other movable member away from the body.

A modular implant for performing an intervertebral fusion on adjacent vertebral bodies in a patient including a first spacer portion, a second spacer and a container having a first end and a second end, the first end of the container constructed to operably engage a first spacer and the second end of the container constructed to operably engage the second spacer.

An orthopedic distraction device is provided. The orthopedic distraction device includes a first upper paddle for engaging a first bone of a joint, a lower paddle for engaging a second bone of the joint and a displacement mechanism. The displacement mechanism includes a drive assembly operable to move the upper paddle relative to the lower paddle. The lower paddle is releasably connected to the displacement mechanism.

A method of placing an implant for intervertebral fusion between adjacent vertebral bodies in a patient includes inserting the implant in a space between the adjacent vertebral bodies such that both a first intervertebral spacer body and a second intervertebral spacer body contact each of the adjacent vertebral bodies. The first intervertebral spacer body is spaced apart from the second intervertebral spacer body. An expandable container portion of the implant disposed between the first intervertebral spacer body and the second intervertebral spacer body is filled with fill material such that the expandable container expands to contact each of the adjacent vertebral bodies.

A surgical instrument for the revision of prostheses, comprising a handpiece in which a cylinder is arranged, wherein a piston element is associated with the cylinder, as well as a switching element and a chisel tool, wherein the chisel tool is arranged axially movably mounted at one end of the handpiece, wherein the chisel tool is fastened to the handpiece in a loss-proof manner, wherein the piston element is axially movably arranged in the cylinder, wherein the piston element can be set in motion by means of a fluid, wherein the piston element is configured to induce a pulse directed in the direction of the chisel tool for driving the chisel tool into a prosthesis stem interspace associated with the prosthesis, wherein the piston element is configured to induce a pulse, directed opposite to the chisel tool for driving the chisel tool out of the prosthesis stem interspace.

A spinal implant for placement between vertebral bodies includes a first member for engaging one of the vertebral bodies, a second member for engaging an opposing one of the vertebral bodies, and at least one extendable support element for inducing movement of the entire first member away from the second member. The first member is connected to the second member such that the first member moves away from the second member by a larger distance at a first end of the implant than at a second end of the implant. A connecting member may connect the first and second members together at the second end of the implant. The connecting member may include one or more rotatable linkages, or the connecting member may be an extension of one of the first and second members slidably received within a track defined within the other of the first and second members.
