Techniques and systems for distracting a spinal disc space and supporting adjacent vertebrae are provided. Trial instruments are insertable into the disc space to determine a desired disc space height and to select a corresponding implant. Implants can be also be self-distracting and the implant providing the desired disc space height can be implanted in the spinal disc space.
摘要:
The present invention relates to a method for enhancing ingrowth of host bone comprising: modifying a bone graft structure to provide an ionic gradient to produce a modified bone graft structure; and implanting the modified bone graft structure. The present invention also relates to a method of enhancing the binding of growth factors and cell cultures to a bone graft structure comprising: applying ex vivo an effective quantity of an ionic force change agent to the surface of a bone graft structure to produce a binding-sensitized bone graft structure; implanting said binding-sensitized bone graft structure into a host bone; and administering to said binding-sensitized bone graft structure a molecule, a cell culture or a combination thereof.
摘要:
An improved osteoimplant device and method for producing it. Bone particles are mixed with a polymer and a solvent. The mixture is formed into the shape of an osteoimplant and substantially all of the solvent is removed. The osteoimplant may be osteoinductive, osteoconductive, and load-bearing.
