US 8,940,051 B2 · Interbody device insertion systems and methods

Abstract

Provided is a system for implanting an interbody device into a disc space located between a first and second vertebra includes a guide frame including a guide member having an opening. The system further includes an implant trial including an elongated body and a base plate coupled to the elongated body. The elongated body of the implant trial is releasably coupled to the guide member of the guide frame during use such that the opening guides longitudinal movement of the implant trial relative to the guide frame. The system still further includes a dilator operatively coupled to the elongated body during use for distracting the disc space. The system still further includes an insertion instrument including an elongated body and an insertion member coupled to the elongated body. The elongated body of the insertion instrument is releasably coupled to the guide member of the guide frame during use such that the opening guides longitudinal movement of the insertion instrument relative to the guide frame. The insertion member is releasably coupled to at least a portion of the interbody device during use.

Dependent claims

A method of implanting an interbody device into a disc space located between a first and second vertebra, comprising:

inserting a base plate of a first implant trial into the disc space;
inserting a base plate of a second implant trial into the disc space, wherein the second implant trial is coupled to the first implant trial to position the base plate of the first implant trial relative to the base plate of the second implant trial;
inserting one or more dilators into the disc space proximate the base plates of the first or second implant trials to distract the first and second vertebrae;
removing the base plate of the first implant trial and the dilators from the disc space;
and
inserting the interbody device into the disc space in substantially the same position as the base plate of the first implant trial.

A method of implanting interbody devices into a disc space located between a first and second vertebra, comprising:

inserting a base plate of a first implant trial to a selected location at least partially within the disc space, the first implant trial comprising an elongated body and a base plate coupled to the elongated body,
wherein the selected location comprises a selected angle with respect to the sagittal plane of the vertebrae;
inserting a first dilator between the base plate of the first implant trial and the first or second vertebra to distract the vertebrae;
coupling a first guide member of a guide frame to the elongated body of the first implant trial, the guide frame further comprising a second guide member and wherein the first and second guide members of the guide frame are rigidly coupled and positioned at a selected convergent angle relative to one another;
coupling an elongated body of a second implant trial to the second guide member such that a base plate of the second implant trial is inserted at least partially within the disc space, and such that at least a portion of the base plate of the second implant trial abuts a portion of the base plate of the first implant trial;
inserting a second dilator between the base plate of the second implant trial and the endplate of the first or second vertebra to distract the vertebrae;
removing the base plate of the first implant trial and the first dilator from the disc space and uncoupling the elongated body of the first implant trial from the first guide member;
coupling an elongated body of a first insertion instrument to the first guide member such that a first interbody device is inserted at least partially within the disc space in substantially the same position as the base plate of the first implant trial, the first insertion instrument comprising the elongated body and an insertion member coupled to the elongated body, wherein the insertion member is releasably coupled to the first interbody device,
wherein the first interbody device is positioned within the disc space at a selected angle with respect to the sagittal plane of the vertebra;
removing the base plate of the second implant trial and the second dilator from the disc space and uncoupling the elongated body of the second implant trial from the second guide member;
coupling an elongated body of a second insertion instrument to the second guide member such that a second interbody device is inserted at least partially within the disc space in substantially the same position as the base plate of the second implant trial, the second insertion instrument comprising an elongated body and an insertion member coupled to the elongated body, wherein the insertion member is releasably coupled to the second interbody device,
wherein at least a portion of the second interbody device is located at or near the first interbody device;
uncoupling the first interbody device from the insertion member of the first insertion instrument;
and
uncoupling the second interbody device from the insertion member of the second insertion instrument.
