LeU - THE SYSTEM FOR DYNAMIC STABILISATION OF THE LUMBAR SPINE ARCA-MEDiCA Medical Implants

FLEXIBILIT Y AND STABILIT Y FOR HIGHEST COMFORT Le U – The Product and Its History The so-called “U“ was invented by the French physician Dr Jacques Samani and implanted in 1994 for the first time. Dr. Benoît Laurent serves as ARCA-MEDICA’s Managing Partner and co-owns the company. I am a physician myself. I have been working intensively with new techniques and inventions since the early nineties. In 2000, I came across the “U“ and was quickly convinced by its qualities. The “U“, which I encountered while working with the spine surgeon Dr. Friedrich Sgier in Lucerne (Switzerland), presents a...

What Indications mandate the Implantation of Le U ? ■ Le U presents an alternative to the fusion of the spine. It is implanted after decompressing surgery of lumbar canal stenosis and also when the facet joints are athrotic. These two conditions occur either together or in isolation. After decompressing operations of the lumbar spine and resections of athritic joints of the vertebrae, we often witness the problem of an ensuing instability of the spinal segment. The implant, however, stabilizes the operated segment and preserves its flexibility. ■ Another indication is the protection of the neigbouring...

3 Step Choose the right size of Le U with the template. Thus, a perfect fit is guaranteed. Please pay attention to light distractions without kyphosing the segment. An X-ray check may be helpful. The patient is placed on the stomach in neutral position. The median incision is chosen according to the place of the decompression of the neural structures. The decompression can be executed as a unilateral or bilateral "undercutting". This way, the supraspinous ligament can be held to the side, thus preserving it. Now, you remove the interspinous ligament and, possibly, resect hypertrophied spinous...

The Right Forceps In some cases, the gripping jaws of the implant have to be adjusted to the individual anatomy of the spinous processes. 4 Step Using a compression forceps, press the gripping jaws of the Le U together. Under exceptional circumstances, you can use the holes in the gripping jaws for a wire or thread cerclage in order to improve fixation to the spinous processes. Now, you can fix the supraspinous ligament to the spinous process and link it with the fascia. We recommend to insert a drainage into the round of Le U; remove it after two days. Further, we recommend a final X-ray check....

Extension effect The post-op pictures show the dynamic spring effect. Decompression Condition after decompression of a spinal canal stenosis Multiple level Hybrid Le U is placed in addition above a rigid spondylodesis in order to protect the neighbouring segment. Multiple level Due to the design of Le U the gripping jaws are staggered. Le U can be implanted multiple level.
