Bone graft delivery to the intervertebral space is a consistent source of frustration. The devices available jam, deposit graft material at the end of the tool blocking cage insertion and don’t take advantage of the entire area of prepared disk space.
Our first product solves these problems and allows application of autograft and/or bone graft substitute smoothly and efficiently, cutting the time to fill the prepared disk space to several minutes or less. It allows inoculation of bone graft to the most collapsed disk space. Due to its unique biportal extrusion, it applies the graft to the entire prepared disk space leaving a natural void for fusion cage application. This tool allows the surgeon to control the volume of graft material application instead of being limited by the wrong implement.
The section above should be in a box. Next to the box should be another box which displays the Voice over that you and Trey did (ready soon).
I would like a section that gives a highlight option for Instructiions for Use which would go to the following:
Instructions for Use
(Best results will be obtained by following these directions.)
1. Thoroughly prepare the disk space by removal of all disk material.
2. Measure disk material removed to calculate the amount of graft material to prepare. (See chart)
3. Distract the disk space with wedge dilators per the cage manufacturers protocol. NB: A minimum of 8mm of distraction is necessary to safely use the device.
4. Try a sample of the graft material with the delivery device to ensure flowability. The device has been tested with ground local bone graft/iliac crest, Medtronic biologics, DePuy biologics, OrthoFix biologics, Actafuse and ISTO biologics.
5. Insert the plunger/stylet into the empty cannula and insert the complex into the disk space.
6. Attach the funnel and apply the graft material with thumb and finger pressure into the cannula. Push the plunger all the way down to expel the graft material. Apply 1-2 ml of graft with each pass of the plunger.
7. You will feel resistance of flow when the disk space has filled up.
8. Remove the funnel and directly observe the area around the annulotomy/ cannula interface to confirm that graft material has not overflowed.
9. Remove cannula and insert cage per the manufacturer recommendations.
10. Discard after single patient use.
