FUSION IMPLANT DEVICE AND METHOD OF USE |
摘要 |
An intervertebral prosthesis includes a bone graft implant member dimensioned for insertion within an intervertebral space defined between adjacent vertebrae and having at least first and second longitudinal sections with respective first and second cross-sectional dimensions. The first crosssectional dimension of the first implant section is greater than the second cross section dimension of the second implant section to define a stepped region having a retaining surface. Consequently, upon insertion of the implant member within a generally correspondingly dimensioned receiving bed formed within the adjacent vertebrae, the retaining surface facilitates securement therewithin by corresponding engagement with surfaces of the receiving bed. A method for fusion of adjacent vertebrae utilizing the prosthesis is also disclosed.
