At KLS Martin, we strive to restore patient health by finding and developing innovative device solutions that address the individual patient.
Through relationships with clinical experts, we are able to solve challenging problems.
The LSS, longitudinal sternal stabilization system was developed in cooperation with Dr. Jeko Madjarov and Carolinas Medical Center.
This product is available for use in the United States. The LSS is a patent pending design.
Each of the products that KLS Martin develops address the same goal, to restore the patient’s bone through uneventful healing after surgery.
Coughing, exercise, differences in an individuals health or bone quality create unique challenges in healing after the midline sternotomy.
Based on these variables, a single product solution may not offer the ideal solution for all patients.
The most common product, wire fixation, is universally accepted as the standard of care for a simple and effective fixation of the midline sternotomy in healthy patients with good bone quality.
At times where the bone quality or patient health is not optimal for successful wire fixation, surgeons have adopted alternative forms of fixation that are more rigid.
Most of these rigid fixation products rely on the sternal halves to be part of their solution. The bone must be stable and sturdy for anchorage on either side. This is not always the case.
These solutions are also not as easy or familiar to apply compared to wires, nor have the same simple steps as wire for emergent reentry.
The LSS solution does not rely on the strength of the sternal halves for stability, nor does it replace wires. The LSS solution reverses the notion that wires are the problem.
The LSS reinforces the sternal halves to improve the success of wire fixation.
During design of the LSS system, a comparison was made using bench model testing. Traditional wire alone and with the LSS solution was applied to a simulated bone model with a midline sternotomy.
A testing device held the two sternal halves lateral of the ICS area. Force was applied laterally.
As increasing force was applied to the wire only model, the wires cut transversely through the simulated bone until it was completely compromised.
In the LSS model, there was little movement until very high forces were applied. At that point, the wires began to untwist. The wires did not cut through the sternum.
In this testing, the LSS shows that it avoided the cutting of wires into the sternum, and kept the sternal bone intact, even after the wires had failed by untwisting.
The sternum depth is noted for proper screw lengths.
The plates are secured with drill free locking screws via the maxDriver, a smart ultra-fast battery powered screwdriver.
The drill free screws engage and lock slightly below the anterior surface of the plate.
The LSS plate secures the wires in a static location with an ‘intimate fit’ into the plate.
Next, the sternal wires are placed
The sternal halves are loaded and pull against the wire. The wire resists and disperses the load onto the LSS plates and screws.
