- “T” handle for cage insertion (Code: OSCH)
- Spacer trials for each of the sizes in the table above (Codes as per table)
Cage Insertion Technique
- Insert the trial into the space where the disc has been removed.
- Release the retractors.
- Ensure that the trial fits correctly in the disc space.
- If the fit is correct, prepare the cage size that corresponds to the trial size and prepare it with bone (allograft, or autograft bone). See appendix A.
- Insert the cage into the disc space, ensuring that it is positioned centrally with reference to the lateral aspects.
- The depth of the cage is determined by the stopper on the inserter. (This depth is ideally about 1mm posterior to the anterior cortex.)
- The cage can be filled with either autograft bone (e.g. from the iliac crest), allograft bone (e.g. lyophilized bone, freeze dried bone), or else bone substitute (e.g. tri-calcium phosphate, bi-calcium phosphate, etc).
- The choice of void filler used is the surgeon’s preference after the necessary benefits have been carefully considered.
- Void filler should ideally protrude fractionally from both the cephalad and the caudal planes of the cage to allow for the initial resorbtion that occurs.
