The SinuRod device is a superior replacement for a standard rod implant used in lumbar spine surgery. It has been designed to address the challenging issue of screw head collision, particularly in minimally invasive percutaneous (MIS) pedicle screw procedures, as well as open procedures when extended tab reduction screws and/or towers are used. Screw head or tower collision causes stress on the construct components, leading to false torque and/or false tightening where the screw/rod locking mechanism is not properly engaged. It also creates additional challenges for the application of compression and distraction forces on the construct and causes tissue necrosis where the extended screw tabs or towers collide or overlap. SinuRod will reduce the struggle that surgeons experience during this final stage of the procedure, as well as the likelihood for incision extension in MIS procedures, and the potential of "false torque" and "false tightening" creating subsequent construct loosening. Prototypes of the technology are available, and cadaver and dry lab evaluations have been completed.
Overview: The current gold standard for a 1-level MIS procedure is a Lordotic rod that forces head collision in single and multi-level surgeries. Standard, pre-formed radii causes screw collision regardless of the number of level in the surgery.
Applications: MIS pedicle screw procedures, spondylolisthesis reduction, percutaneous L5 S1-illiac fixation, procedures in which lordotic & kyphotic fixation points need to be longer
Advantages: Extends the range of poly-axial screw-rod interface; eliminates collision issues created by false torque, etc.; allows for improved compression & distraction
