    The C2-Pars Interarticularis Screw as an Alternative in Atlanto-Axial Stabilization. A Biomechanical Comparison of Established Techniques
    (TURKISH NEUROSURGICAL SOC, 2018-01-01) Schleicher, Philipp; Onal, Mehmet Bulent; Hemberger, Frank; Scholz, Matti; Kandziora, Frank
    AIM: To compare four different atlantoaxial stabilization techniques. MATERIAL and METHODS: Eight human cervical spines (segments C0-C3) were tested in flexion/extension, lateral bending and axial rotation. Range of Motion (ROM) at a 1.5 Nm load was recorded. After native testing, the Harms (HARMS), pars screw (PARS), intralaminar screw (INTRA) and anterior transarticular screw (ATA) constructs were applied in a random order. RESULTS: FLEXION/EXTENSION: mean ROM (+/- SD) in native state was 15.9 degrees (+/- 7.6 degrees)
