Aero-LL is a Lateral Lumbar Interbody and Fixation System that features Aerofoil™ Compression Technology, the only in-line LLIF (lateral lumbar interbody fusion) device to offer compression across the disc space.
Shaped like inverted plane wings, Aero-LL’s unique anchors are designed to pull the vertebral bodies towards the implant as they are inserted, creating compressive forces at the implant‑to‑endplate interface. This system features a fully guided, in-line, rail-based instrument set to help you accurately place the implant and anchors, and achieve interoperative reproducibility.
- StraightForward insertion with Aero-LL’s precision-guided instruments, which deliver anchors within a constrained system
- Anchors designed to secure Aero-LL to the vertebral bodies with Aerofoil Compression Technology
- Designed to create compressive forces that are distributed uniformly across the implant-to-endplate interface
About LLIF
The Lateral Lumbar Interbody Fusion (LLIF) procedure is a minimally disruptive surgical technique in which the surgeon approaches the spine from the side of the patient’s body, rather than the front or back as in traditional spine surgeries. This side (lateral transpsoas) approach can reduce the risk of injury to muscles, nerves, and blood vessels.
The XLIF and DLIF are types Lateral Lumbar Interbody Fusion, or LLIF, which is a category of fusion in which the disc in the front of the spine is removed and replaced with an implant containing a bone graft to set up the condition for the two vertebrae to fuse together through the disc space.
XLIF uses a minimally invasive, transpsoas approach to the spine. The surgeon uses his or her finger to perform blunt dissection through a posterior paraspinal incision to escort dilators and a guide wire into position directly over the psoas muscle. Using his or her finger the surgeon is able to create a retroperitoneal space and protect the viscera and prevent possible injury.
With the DLIF technique, some surgeons have chosen to perform this procedure through a single miniopen lateral approach without the use of the posterior incision to create the retroperitoneal space. With the single incision, the layers of the abdominal wall are directly visualized, and the retroperitoneal space is created under direct vision with passage of instruments through the psoas. In addition, the use of electrophysiological monitoring, including triggered and freerunning electromyography (EMG), reduces the likelihood of injury to the lumbosacral plexus when accessing the disc space through the psoas muscle. Dilators, which contain insulated tips allow for EMG monitoring as they are introduced via the transpsoas approach to the disc space. If a dilator passes in proximity to the lumbosacral plexus, the surgeon is warned both visibly on a graphic display and also via auditory feedback. The surgeon can then adjust his or her trajectory to reduce the likelihood of neural injury.
About Stryker
Stryker Corporation is a Kalamazoo, Michigan based medical equipment firm which develops and produces medical implants,,surgical and imaging technologies, as well as patient handling and emergency medical equipment.
Stryker’s history is rooted in innovation. When Dr. Homer Stryker, an orthopaedic surgeon from Kalamazoo, Michigan, found that certain medical products were not meeting his patients’ needs, he invented new ones. As interest in these products grew, Dr. Stryker started a company in 1941 to produce them. The company’s goal was to help patients lead healthier, more active lives through products and services that make surgery and recovery simpler, faster and more effective.
Today, Stryker is a global leader in the medical technology industry. Company growth is based on an unparalleled variety of high-quality, innovative products and services that create cost-effective solutions and improve people’s lives – which we achieve through the dedication of our over 25,000 employees globally in 2013. http://www.stryker.com
