Is there an optimal patient stance for obtaining a lateral 36″ radiograph?
STUDY DESIGN: Scoliosis patients were prospectively x-rayed in three positions with independent analysis. OBJECTIVES: To determine if one positioning technique provides superior visualization of critical landmarks (C7, T2, T12, L5-S1) and to determine any position dependent variations in regional measures or sagittal balance. SUMMARY OF BACKGROUND DATA: Different techniques for positioning patient’s arms are used for 36″ lateral radiograph with no data on relative effects. METHODS: A total of 25 scoliosis patients were prospectively studied with 36″ lateral radiographs in three positions varying arm location (straight out, partially flexed, and the “clavicle” position). Films were analyzed independently by three surgeons. Vertebral landmarks were scored for clarity; and lordosis, kyphosis, and global balance were analyzed. Statistical analysis was done with a General Estimating Equations model. RESULTS: The overall visualization score for the clavicle position was superior to either th
