The SYNAPSE™ System is an enhanced set of instruments and implants, including clamps, variable axis screws, hooks, transconnectors, transverse bars and rods, designed for posterior stabilization of the upper spine. These implants provide the flexibility required to accommodate variations in patient anatomy.The SYNAPSE System uses 3.5 mm and 4.0 mm titanium alloy rods. When combined with the Occipital Cervical Fusion System and the Universal Spinal System, constructs can extend from the occiput to the lower spine.
Benefits:
- 100° total cone of angulation on all 3.5 mm and 4.0 mm diameter cancellous screws:Allows flexibility for screw placement and rod capture
- 3.5 mm and 4.0 mm diameter titanium alloy rods:Improves stiffness and strength: 4.0 diameter rod is 49% percent stronger and 71% percent stiffer than 3.5 diameter rod*
- Screw driver features a patent-pending threaded holding sleeve:Assists in disengaging the screw from the hex or T15.Eliminates screw “sticking” providing controlled screw insertion
*Yield strength is the point on the stress-strain curve beyond which the material begins deformation that cannot be reversed upon removal of the loading, as demonstrated in the cantilever bend model. Testing on file at DePuy Synthes Companies.
About Posterior Cervical Fusion
Posterior Cervical Fusion is a procedure intended for the stabilization of the cervical spine through a posterior approach. The procedure is commonly performed using hooks, plates, screws and rods as an adjunct to the fusion. Posterior cervical fusion is performed to treat instabilities which arise from: degenerative disc disease, spondylolisthesis, spinal stenosis, fracture/dislocation, atlantoaxial fractures with insatiability, occipito-cervical dislocation, revisions of previous cervical spine surgery and tumors.(Source: Depuy Synthes)
