In-situ formed intervertebral fusion device and method

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.

3D printed trans-modular scaffolds for grafting applications in segmental bone defects

A bone repair scaffold having two moduli that match those of the cancellous and cortical bone in a patient receiving a bone graft/implant. The bone repair scaffold possesses increased mechanical properties to sustain physiological loading and biologically active capability to facilitate bone fusion. The bone repair scaffold may be 3D-printed, which allows for a variety of scaffold designs and configurations. Pore size, interconnected porosity, shape, and modulus of the bone repair scaffold may be modified for different bone graft applications, whether it is used as filler for bone cancer resections or trauma, or as a fusion device in cases of surgery. Depending on the defect location of the bone shaft, the relative porosity of the scaffold may be modified to account for changes in cortical bone thickness. A method for treating a bone defect using the bone repair scaffold is also disclosed.
