Abstract
A method comprising the steps of: providing an implant support including a first portion frangibly connected to a second portion that defines an implant cavity and supports a bone fastener; connecting a surgical introducer instrument with the implant support and engaging the surgical introducer instrument with the bone fastener; percutaneously introducing the surgical introducer instrument, implant support and bone fastener assembly to a surgical site including tissue; attaching the second portion with the bone fastener to the tissue; and removing the first portion from the second portion. Systems, fasteners and instruments are disclosed.
Claims16
A method of treating a spine, the method comprising the steps of:
- providing an implant support including a first portion connected to a second portion that defines an implant cavity and supports a bone fastener;
- connecting a surgical introducer instrument with the implant support and engaging the surgical introducer instrument with the bone fastener such that a distal end of the bone fastener is generally adjacent the second portion;
- percutaneously introducing the surgical introducer instrument, implant support and bone fastener to a surgical site including tissue;
- extending the bone fastener through the second portion and into bone generally adjacent the second portion;
- disposing a spinal rod with the implant cavity;
- removing the first portion from the second portion;
- and
- mating threads of a setscrew with threads of the second portion such that the set screw engages the spinal rod to fix the spinal rod relative to the bone,
- wherein the implant support further includes a relatively flexible member that supports the bone fastener, and
- wherein the member comprises a gasket and further including the step of engaging the second portion with the gasket to seal the implant cavity.
A method of treating a spine, the method comprising the steps of:
- providing an implant support including a first portion connected to a second portion including an inner surface that defines an implant cavity;
- connecting a surgical introducer instrument with the implant support and engaging the surgical introducer instrument with a bone fastener such that a distal end of the bone fastener is generally adjacent the second portion;
- percutaneously introducing the surgical introducer instrument, implant support and bone fastener to a surgical site including tissue;
- extending the bone fastener through the second portion such that a shaft of the bone fastener penetrates bone and a head of the bone fastener engages the inner surface, the head being fixed relative to the shaft;
- and
- removing the first portion from the second portion after the step of extending,
- wherein the implant support further includes a relatively flexible member that supports the bone fastener, and
- wherein the member comprises a gasket and further including the step of engaging the second portion with the gasket to seal the implant cavity.
