Study design: This is a cross-sectional prospective study of diagnostic accuracy. Objective: The aim of this study was to establish the diagnostic accuracy and cut-off points of the surface topography parameters. Methods: Seventy-seven participants of both genders, aged between 7 and 18 years old, were consecutively included. Each participant was evaluated using two randomly-chosen consecutive procedures, by means of a surface topography scanner and a Scoliometer®. In this study, the angle of trunk rotation (ATR) determined using the Scoliometer® was taken as reference. For statistical purposes, a multiple linear regression analysis was made to establish which surface topography parameters have the highest standardized beta coefficients (β). Based on the β values, two topographic parameters were chosen (apex of the curve and trunk rotation) to compose the Receiver Operating Characteristic (ROC) analysis. Results: The cut-off points for the topographic parameters were established as ATR <5° for subjects without scoliosis and ≥8° for severe scoliosis. The ROC curve analysis for the apex of the curve was significant (p<0.001) with an area under the curve (AUC) ranging between 76% [cut-off point 4.4 mm] for the subjects without scoliosis and 84% [cut-off point 9.4 mm] for the subjects with severe scoliosis. For the trunk rotation parameter, the AUC was also significant, ranging between 68% [cut-off point 1.5°, p=0.023] for subjects without scoliosis, and 73% [cut-off point 4.8°, p=0.018] for the subjects with severe scoliosis. Conclusion: Surface topography provides adequate accuracy and can be used to evaluate the presence of the thoracic idiopathic scoliosis.

Purpose: Pinpoint instrumentation is pivotal in cervical spine surgery in order to protect sensitive structures such as spinal cord or vertebral arteries. The aim of this study was to investigate the accuracy of neuro-navigated rotational fluoroscopy-guided screw positioning in the cervical spine employing a novel classification system. Methods: In procedures of dorsal cervical spine stabilization screw positions documented by rotational fluoroscopy were retrospectively evaluated. Accuracy of screw placement was analyzed using a new eight-grade scoring system with particular attention to the spinal canal, neuroforamina, and vertebral arteries. In addition, intra- and postoperative revision rates, as well as clinical and neurological outcome were evaluated. Results: One-hundred-forty-five patients with dorsal stabilization of the cervical spine were included. Of the 925 screws placed, 877 (94.8%) showed optimal positioning in the primary 3D image control. Differentiating between less and more than 50% of the screw diameter, 15 (1.6%) and 2 screws (0.2%) protruded into the transverse foramen. The pedicle or lateral mass were exceeded craniocaudally by 8 (≤50%: 0.9%) and 3 screws (>50%: 0.3%), respectively. Laterally, the pedicle or mass was exceeded substantially by 6 screws (0.6%). Medially, 8 (≤50%: 0.9%) vs. 6 screws (>50%: 0.6%) exceeded the wall of the pedicle or lateral mass. No patient underwent secondary surgery due to initial screw mispositioning. An improvement of the preoperatively indicated pain levels was documented in 87 of 114 patients (76.3%) with adequate follow-up. Conclusions
