Abstract
Apparatus and methods include implants insertable into the body of a patient for posterior lateral fusion of one or more vertebral levels. The implant can be osteoinductive and/or osteoconductive to facilitate or initiate the fusion between two or more bony portions of the spinal column. The fusion implant can be used in isolation or in conjunction with a posterior stabilization construct.
Claims20
An implant system, comprising:
- at least a first anchor engageable to a first vertebra and a second anchor engageable to a second vertebra;
- an elongate connecting member extending along an axis between a first end and an opposite second end, said connecting member including a length between said first and second ends sized to extend between and be engaged to said first and second anchors when said first and second anchors are engaged to the first and second vertebrae;
- and
- an elongate fusion member extending between a first end and an opposite second end, said elongate fusion member being comprised of bone growth material and including a length between said first and second ends sized for positioning in contact with bony portions of the first and second vertebrae when the elongate fusion member is positioned alongside said connecting member.

An implant system, comprising:
- at least a first anchor engageable to a first vertebra and a second anchor engageable to a second vertebra;
- and
- an elongate stabilization member including a connection portion extending along a longitudinal axis between a first end and an opposite second end, said connection portion including a length between said first and second ends sized to extend between and be engaged to said first and second anchors when said first and second anchors are engaged to the first and second vertebrae, said elongate stabilization member further including a deployable fusion portion carried by said connection portion, said fusion portion including a first collapsed condition for insertion of said elongate stabilization member between said first and second anchors and a second deployed condition projecting outwardly from said connection portion sized to engage bony portions of the first and second vertebrae, said fusion portion including an interior with bone growth material in said interior in said deployed condition to facilitate fusion of the bony portions of the first and second vertebrae.
A method, comprising:
- inserting through an incision in a patient an elongate connecting member between first and second anchors engaged to posterior elements of the first and second vertebrae;
- engaging the connecting member to the first and second anchors;
- inserting a fusion member through the incision to a location adjacent to the first and second anchors and the connecting member and positioning the fusion member in contact with bony portions of the first and second vertebrae;
- and
- engaging the fusion member to at least one of the first and second anchors and transverse processes of the first and second vertebrae.
