Objective: To investigate the presence of a "functionally normal" cervical lordosis and identify if this and the amount of forward head posture are related to neck complaints.
Methods: Using the posterior tangent method, an angle of cervical lordosis was measured from C2 through C7 vertebrae on 277 lateral cervical x-rays. Anterior weight bearing was measured as the horizontal distance of the posterior superior body of the C2 vertebra compared to a vertical line drawn superiorly from the posterior inferior body of the C7 vertebra.
Purpose: The study was performed to evaluate the performance of digital fixed-mounted angiographic C-arm systems in the operating room as used by surgeons, cardiologists, and interventional radiologists.
Methods: An observational study in the operating room was performed, along with a structured questionnaire and semi-structured interviews. Twenty interventions were observed at 5 sites.
