Summary (Kyle Halfacre)
Executive Summary Background
The majority of procedures today utilize the pedicle screw stabilization system.The system screws into the pedicle.It fuses vertebra together.
Screws tend to brake of come out of bone.Pedicle can brake off.
Executive Summary What We Are Doing
There a many problems associated with the current pedicle screw stabilization system (Some of which can be life threatening).By eliminating the screws, we are drastically reducing the trauma to the bone.We are supporting the spine without any sort of cutting, drilling or grinding on the bone. We are developing a system that is durable and reliable.
Executive Summary Why It Is Needed
The only options with current systems are; A complete inter-vertebral fusion which does not
allow for any motion and generally utilizing the pedicle screw system.
A dynamic system which has a high risk of failure (currently being recalled).
Or other, more exotic systems that are still very risky extremely traumatic and extremely invasive (meaning, they are very painful requiring long recovery time).
Executive Summary Why It Is Needed
Most of these systems require large and or heavy hand tools and/or large and heavy power tools for cutting and/or bending strong materials during the installation procedure. (difficult installation usually means long procedure, very invasive and extremely traumatic)
Executive Summary How It Is Different
Instead of drilling, our system will use Pressure from pseudo-elastic, spring, or
memory-shape alloy High friction microstructure Mechanical hold from shape to secure our device
into place. Instead of complete fusion between vertebrae (which immobilizes the spine), our system will utilize
Sintered alloy matrixInfused with a bone morphogenetic protein (to
induce bone growth into it) Bone fusion to Hardware which will allow motion
between vertebrae.
Executive Summary Deliverables
We will deliver an effective and efficient device.THE SPINESTB WILL RETAIN THE SPINE’S NORMAL
FUNCTION!!!By design the SPINESTB will be simple to assemble and
simple to install. (Lowering the possibility for human error)
The SPINESTB will be minimally invasive thereby reducing recovery time.
The SPINESTB will cause little to no trauma to the bone tissue during installation and during function.
The SPINESTB will allow for intra-vertebral disk recovery and healing.
The SPINESTB will be modular, for easy modification and upgrade.

Technical Discussion Literature Review Summary
Introduction
• 400,000 lower back operations performed every year in the United States.
• Herniated or Ruptured Disk, Lumbar Spinal Stenosis, and Osteoarthritis.
Anatomy of the Vertebrae
• Facet joints, spinal canal, nucleus and the annulus.• L1-L5, are the ones most frequently involved in back pain.
• The highest activity is located on the segments L3-L4 and L4-L5.
• The most strain is taken by the segments L4-L5 and L5-S1.
Technical Discussion Literature Review Summary
One Level Fusion• The one level fusion surgery normally contains four pedicle
screws and two rods along with connective hardware.• Approaches: Anterior Lumbar Interbody fusion,Posterior
Lumbar fusion Interbody Fusion, Transforaminal Lumbar Interbody Fusion.
Dynamic Stabilization systems• One of the most prevalent systems available today for spine
stabilization is the Dynesys Neutralization system.
Technical Discussion Literature Review Summary
Spinal fusion through the use of bone cement
• Cements introduced in 1940.
• The most common use is in securing artificial joints in place. One application is in hip replacement.
• The cement is used to fill gaps between the hardware that is inserted into hollowed out hip bone and the bone itself.
