The purpose of this paper was a biomechanical review of a new device, BTS (Bilateral Transarticular Spacer), to stabilize atlanto-axial motion. The biomechanical performance of the BTS and Harms techniques were compared using 6 cadaveric spines. The BTS was also designed to lessen the risks of damaging life sustaining nerves and arteries during placement at the atlanto-axial joint. Two hypotheses were postulated: 1.) The BTS will be able to stabilize the atlanto-axial joint after a type 2 odontoid fracture; and 2.) BTS will function biomechanically similar to the traditional Harms stabilization technique. In conclusion, the testing performed provided initial feasibility evidence that the new BTS device reduced atlanto-axial motion (P < 0.01) and provided stabilization similar to the Harms technique (p<0.01) with loads of 1.5 Nm in flexion-extension, axial rotation, and lateral bending.
