Analyzing spinopelvic parameter differences between standing and supine position

This study aimed to investigate the differences in spinopelvic parameters, including pelvic tilt (PT), sacral slope (SS), lumbar lordosis (LL), and pelvic incidence (PI), measured in standing and supine positions using standing computed tomography (CT) scans. Due to the limited availability of standing CT scans in Indonesia, this review analyzed data from combined Web of Science, Scopus, and PubMed databases. Following a comprehensive literature search, the full text of relevant articles was downloaded and evaluated for eligibility based on predefined inclusion and exclusion criteria. The final list of studies included 11 for LL, 8 for SS, 6 for PI, and 11 for PT. The results showed significant differences in SS and PI measurements between standing and supine positions in normal patients (p<0.05). However, no significant differences were found in LL, PT, and all spinopelvic parameters in patients with lumbar disc degeneration (p>0.05). These findings suggest that supine position CT scans can effectively and accurately represent the patient’s condition for certain spinopelvic parameters, particularly in patients with lumbar disc degeneration.
