LORDOTIC SPINAL IMPLANT |
摘要 |
A lordotic implant has a frusto-conical shape with external threads. Prior to placement of the implant, vertebrae are distracted in a manner to provide a desired lordosis between the vertebrae. The pre-distracted vertebrae are then tapped to provide a tapped bore having a geometry matching the conical geometry of the implant. The threaded implant is then placed within the pre-tapped conical bore. A hollow spinal tap is disclosed which collects debris that could otherwise obstruct implant insertion. |
