Patent ID: 7618460

Claim:
A method of treating a spinal deformity, said method comprising: surgically preparing an intervertebral space between endplates of adjacent vertebrae; providing a modular implant comprising an assembly of individual cortical bone-derived components, said individual components comprising: a first strut having a first bone-engaging portion, an opposite second bone-engaging portion, a first end defining an impact surface, and a second end opposite said first end and defining a curved end surface to facilitate impaction of the implant into the intervertebral space, a second strut spaced from said first strut, said second strut having a third bone-engaging portion, an opposite fourth bone-engaging portion, a third end defining an impact surface, and a fourth end opposite said third end and defining a curved end surface configured to facilitate impaction of the implant into the intervertebral space, said second strut in cooperation with said first strut defining an internal space, and a cross-member; assembling the modular implant by coupling the first and second struts to one another with the cross-member to form an assembled modular implant, the cross-member positioned within the internal space and extending from the first strut to the second strut; engaging an impaction tool with the impact surfaces of the first and second struts; positioning the curved end surfaces of the first and second struts adjacent the intervertebral space; and impacting the assembled modular implant into the intervertebral space.
