"To biomechanically compare plated constructs using nonlocking bone-screw-fasteners with interlocking threads verses locking screws with traditional buttress threads in geriatric female bone."
"In female geriatric bone, constructs fixed with bone-screw-fasteners incorporate multiplanar interlocking thread geometry and performed similarly to traditional locked plating."

"Instrumentation with the SI screw fixation device significantly reduced mean joint ROM compared to the destabilized condition, with similar ROM in flexion-extension and axial rotation, and it significantly reduced ROM in lateral bending compared to that for the intact joint. The ROM values observed with the instrumented
condition were comparable to levels of mobility considered favorable for spinal fusion."

"We hypothesized that a new Bone-Screw-Fastener with an innovative interlocking thread design demonstrates increased resistance to torque stripping forces compared with the buttress screw, without compromising pullout strength."
"These data demonstrate the superiority of the new Bone-Screw-Fastener over the conventional AO buttress screw regarding protection from torque stripping forces. In addition, the new thread design that interlocks to the bone does not sacrifice axial pullout resistance conveyed by the buttress screw."
Patient Safety in Surgery
"A new patented Bone-Screw-Fastener was recently designed that is based on an interlocking thread technology. The new fastener provides distributive forces from the threads onto the bone and therefore resists loads in multiple directions."
Implications of hypothesis
"Once validated in multicenter RCTs, the new Bone-Screw-Fastener may drive a change in paradigm with regard to its innovative biomechanical principles and biologic bone preservation for surgical applications requiring screw fixation."
