Devices and techniques for a posterior lateral disc space approach
View Patent ↗This invention relates to devices and instruments for implant insertion through a posterior lateral opening to the disc space. The instruments include an implant inserter, and the devices include a spinal fusion implant engageable by the implant inserter. The implant provides bilateral support of the adjacent vertebrae when inserted into the disc space from a postero-lateral approach.
1. A method for inserting an implant in a spinal disc space of a patient, comprising:
accessing the spinal disc space;
preparing the spinal disc space for insertion of the implant;
engaging the implant to an inserter instrument in a first position relative to a proximal portion of the inserter instrument, the proximal portion being movable relative to the implant to a second position;
selecting one of the first position and the second position; and
inserting the implant in the spinal disc space with the proximal portion of the inserter instrument in the selected position.
2. The method of claim 1 , further comprising: moving the proximal portion of the inserter instrument to the other of the first position and the second position during insertion of the implant.
3. The method of claim 1 , wherein selecting one of the first position and the second position includes pivoting the proximal portion of the inserter instrument relative to a distal implant engaging portion of the inserter instrument.
4. The method of claim 1 , further comprising applying a pushing force to the inserter instrument during insertion of the implant in the spinal disc space.
5. The method of claim 1 , further comprising:
engaging an alignment instrument with the inserter instrument; and
inserting the implant in the spinal disc space so that the alignment instrument aligns with an anatomical feature of the patient.
