An expandable spinal implant is disclosed. The implant includes a plurality of ribs which are deformable between first and second states. In the first state, the ribs present a generally cylindrical implant. In the expanded second state, the ribs are arced outwardly to define a generally spherical implant. A tie mechanism is provided for urging the ribs between the first and second states and for holding the ribs in the expanded state. A novel surgical method is disclosed for stabilizing the spine by inserting the implant in the first state between opposing vertebrae and expanding the implant to the second state.
An implant for insertion into a bore formed between opposing vertebrae, said implant comprising: a plurality of ribs each including a plurality of voussoir-shaped blocks with said ribs deformable in response to a deforming force to change from a first shape to a second shape, said ribs in said first
An implant for insertion into a bore formed between opposing vertebrae, said implant comprising: a plurality of ribs each including a plurality of voussoir-shaped blocks with said ribs deformable in response to a deforming force to change from a first shape to a second shape, said ribs in said first shape being generally linear with opposing surfaces of contiguous blocks being spaced apart and said ribs in said second shape being arched with opposing surfaces of said contiguous blocks being in at least partial contact; and applying means for applying said deforming force to said ribs.
