An orthopedic device for implanting between adjacent vertebrae comprising: an arcuate balloon and a hardenable material within said balloon. In some embodiments, the balloon has a footprint that substantially corresponds to a perimeter of a vertebral endplate. An inflatable device is inserted through a cannula into an intervertebral space and oriented so that, upon expansion, a natural angle between vertebrae will be at least partially restored. At least one component selected from the group consisting of a load-bearing component and an osteobiologic component is directed into the inflatable device through a fluid communication means.

A spinal bone graft includes one or more cortical bone portions forming a first unit. The first unit includes an engagement surface for contacting bone, and a mating surface. The mating surface forms at least one first undercut. The bone graft also includes one or more cortical bone portions forming a second unit. The second unit includes an engagement surface for contacting bone, and a mating surface. The mating surface forms either at least one second undercut, or at least one connector. In the former, at least one connector is received in each of the first and second undercuts to interconnect the first and second units. In the latter, the at least one connector of the second unit is received in the first undercut of the first unit to interconnect the first unit and second unit.

Methods for surgically adjusting a curvature of a spine are disclosed. The methods provide for controlling the alignment of bony structures, such as vertebral bodies or portions thereof, as they are moved relative to one another during a surgical procedure. An intrabody implant disclosed and methods of use are also disclosed. The implant has an inclined surface, forming a wedge or other shape having, for example, an acute angle adapted to be placed between at least two separated portions of a single bony structure (such as a vertebral body). In some embodiments, the implant may be used to support portions of a vertebral body that have been separated surgically as part of a pedicle subtraction osteotomy and to orient the portions at a more predictable lordotic angle.

An apparatus and methods are provided for a tapered implant for treating osteochondral defects. The tapered implant comprises a top portion that includes a shape that approximates an osteochondral surface to be replaced. A bottom portion of the tapered implant is configured to be implanted into a hole drilled in bone. A cylindrical sidewall of the tapered implant has a diameter that decreases from a first diameter of the top portion to a second diameter of the bottom portion. The tapered implant comprises any monophasic synthetic material suitable for implantation into bone, including any of silicone, bioglass, peek, polyethylene, titanium, and cobalt chrome.
