TheraCell launches demineralized bone fiber pedicle screw anchorTheraCell last week launched its demineralized bone fiber bone anchor at the North American Spine meeting in Chicago.
The TheraFuze anchor is made of demineralized cortical bone fibers and tests have shown more than double the pullout force versus screws without fiber anchor. Testing in a revision surgery model showed that it restored or improved original pullout force without having to increase hole size or without having to use other materials. The anchors are sized to be used with screw lengths of 5.5mm, 6.5mm and 7mm.
“The ability to augment screws at the time of insertion and immediately enhance pull-out and toggle resistance with a product that also has osteogenic potential is very unique and attractive. TheraFuze DBF Fiber Anchors will provide a valuable adjunct in compromised bone as well as in long fusion constructs where screw-bone failure remains a clinical problem,” Dr. Frank Phillips, director of spine surgery at Rush University Medical Center and TheraCell board of directors member, said in a news release.
