Abstract

Implants (77, 84) for use in the spinal column are disclosed. The implants (77, 84) comprise a bone allograft (91, 100) coupled with a non-allograft plate (78A, 78B; 85; 93). The plate (78A, 78B; 85; 93) has ends (79A, 79B;
86A, 86B; 95A, 95B) that fasten to opposing spine segments (10), and an intermediate portion (80, 87, 94) that engages the allograft (91, 100) using deformable fingers (99), or with a hollow portion (81, 87, 101) sized to receive and hold part of the allograft (91, 100), or with fixed tabs (92A, 92B). Methods of using the implants are also disclosed.
