Premia Spine launches ProMIS fixation system at ISASS, reports first cases performed

228

Premia Spine has launched the ProMIS fixation system with its Advanced MIS screw placement at the 2016 International Society for the Advancement of Spine Surgery Meeting (ISASS; Las Vegas, USA).

 

Steven DeLuca, from the Orthopedic Institute of Pennsylvania (Pennsylvania, USA) and Joshua Ammerman, chairman of the Department of Surgery at Sibley Memorial Hospital (Washington DC, USA) performed the first cases at their respective hospitals with the pedicle screw fixation system.

According to a company release, the ProMIS fixation system offers a choice of screw placement techniques in one instrument kit. Surgeons can select from a k-wireless technique, a direct skin-to-screw placement, a tap-Shidi approach, and a traditional reusable Jamshidi technique. “With interchangeable screw placement techniques, I can switch intraoperatively based on my assessment of the situation,” comments Ammerman.

 

“The direct skin-to-screw placement technique saves several steps and reduces X-ray exposure to my patients and me,” explains DeLuca. “I make my incision, place the screw with an extended k-wire tip at my desired entry point, radiographically confirm orientation, mallet the k-wire tip into the pedicle, and then simply advance my screw as I retract the k-wire into the cannulated screw body.”

Ron Sacher, chief executive officer of Premia Spine, comments, “The ProMIS…saves OR time and reprocessing costs.”

ProMIS also offers a unique pedicle screw which is supplied in an individual sterile pack, according to the release. The Premia Spine screw has a patented surface treatment designed to promote bony ingrowth. The proprietary implant surface technology consists of a unique roughened topography that creates an optimal screw-bone response and promotes bone growth into the micro-crevices of the screw surface.

A peer-reviewed study published in the Journal of Bone and Joint Surgery by Schwartz and Boyan demonstrated significant resistance to pullout forces with the Premia Spine pedicle screw. In the sheep study, 2.3 times the force was required to remove the screw with the surface treatment vs. a non-treated screw.
