Bone graft delivery to the intervertebral space is a consistent source of frustration. Today's end-dispensing tools often jam, depositing graft material solely at the end of the tool, which blocks cage insertion and results in underfilling the entire prepared disk space.
THE SOLUTION: KG™1
The KG 1 solves these problems by enabling the application of bone graft smoothly and efficiently into the disk space. Via its unique dual exit portals, the KG 1 applies the graft to the entire prepared disk space while leaving a natural void for fusion cage application. The time required to fill the prepared disk space is reduced, and without repeated insertion of the KG 1.
An innovative approach to the delivery of graft material
Length: 21 cm • Height: 8 mm • Width: 12 mm • Cannula Volume: 7 ml • Funnel Volume: 10 ml • Radiographic Marker at tip
KG 1: WHAT IS IT?
Watch to learn about the KG 1 and its most important features. (Length: 2:22)
The KG 1 has dual exit portals and a ramp at the internal end, which direct graft material out of the cannula to completely fill the disk space.
40% IMPROVED FLOW
The KG 1 has a rectangular crossection, improving the flow characteristics of bone graft by 40% compared to a round 8mm cannula.

PREPARATION AND USE
Best results will be obtained by following these directions.
The KG 1 is packaged with plunger inserted in the cannula, ready to be inserted into the prepared, distracted disk space. Inspect the package prior to use.
Remove from the sterile package, inspect and handle the KG 1 components in accordance with aseptic techniques and per orthopedic surgical practice.
Distract the disk space with wedge dilators per the cage manufacturers protocol. Maintain the distraction with provisional contralateral pedicle screw fixation. Attention: A minimum of 8mm of distraction is necessary to safely use the KG 1.
Try a sample of the graft material with the KG 1 to ensure flowability.
Insert the plunger/stylet into the empty cannula without the funnel and insert the complex into the disk space. Remove the stylet and attach the funnel.
Apply the graft material with thumb and finger pressure into the cannula. Use the funnel as a bone graft reservoir. Push the plunger all the way down to expel the graft material. If the disk space does not vent the air out of the disk, remove the KG 1 and increase the size of the annulotomy. Apply 1-2 ml of graft with each pass of the plunger. You will feel resistance of flow when the disk space has filled up. Tapping on the plunger will expel residual graft, avoid using a mallet.
Remove the stylet and funnel and directly observe the area around the annulotomy/cannula interface to confirm that graft material has not overflowed.
Remove the KG 1 and insert cage per the manufacturer recommendations.
Discard the KG 1 with other disposables after single patient use.
Continue with the surgical procedure and instrumentation where indicated.
