The present study was undertaken to determine the surgically relevant parameters of the lumbar vertebrae, including interpedicular distance and vertebral body width. The anteroposterior radiographs of the lumbar vertebrae of 551 (315 women, 236 men) healthy, adult people aged 25 to 50 years were obtained with an electronic digital caliper. The mean values of interpedicular distance were found between 21.2 +/- 1.2 mm and 26.1 +/- 1.9 mm from the levels of L1 to L5 in women and between 21.9 +/- 1.1 mm and 27.3 +/- 1.9 mm from the levels of L1 to L5 in men. Additionally, the mean values of vertebral body width were between 36.5 +/- 2.6 mm and 43.7 +/- 2.8 in women and between 39.8 +/- 2.6 mm and 47.2 +/- 2.8 mm in men from the levels of L1 to L5.
