“…The interpedicular distance of the patients in our study was greater than that of Nigerians, Saudis and Koreans, but less than that of Spanish, Indian and healthy Turkish participants. 13,[16][17][18][19] The transverse diameter of the vertebral body in our population was similar to that observed in Nigerians, but was less than that seen in healthy Turkish people. 16,19 The cephalocaudal diameter of the pedicle is greatest at T12 and L1.…”

“…The changes of canal dimensions according to age in the present study were different from the Spanish 16 and Korean 15 series. In age group over 60 years, the midsagittal diameter was smaller than those of younger age group as a result of the hypertrophy or degenerative process of the spine.…”

A morphometric study of the lumbar vertebrae of 126 adult skeletons, 90 Chinese and 36 Indian, of both sexes without marginal osteophytes were performed. In each lumbar vertebra, the cephalad and caudad midsagittal diameters, the interpedicular diameter of the spinal canal as well as the midsagittal and transverse diameters and the height of the vertebral body were measured. The results showed that the midsagittal and transverse diameters, the heights of the lumbar vertebral bodies and the interpedicular diameters of the lumbar spinal canals increased progressively from L₁·to L₅, while the midsagittal diameters of the lumbar spinal canals decreased progressively from L₁ to L₅ in both Chinese and Indian adult skeletons. The lowest mean values of the cephalad and caudad midsagittal and the interpedicular diameters of the spinal canals in Chinese were found to be 5.04 ± 0.15 mm at L₅, 4.67 ± 0.09 mm at L₅ and 25.92 ± 0.20 mm at L₂, respectively, while in Indians they were found to be 4.54 ± 0.18 mm at L₅, 4.25 ± 0.10 mm at L₅ and 25.42 ± 0.22 mm at L₁, respectively. In addition, the mean diameters of the spinal canal and the vertebral body (except the height of the vertebral body) were significantly greater in the Chinese than in the Indian skeletons. The above findings indicate that the mean diameters of both the lumbar spinal canal and the vertebral body vary greatly between Chinese and Indian adults, i.e. there are no mean values of the vertebral dimensions that are valid for all populations. The mean diameters of both the lumbar spinal canal and the vertebral body were greater in Chinese than in Indians, which means that spinal stenosis occurs more easily in Indian than in Chinese adults. In addition, the mean values of the vertebral dimensions in Chinese and Indian adult skeletons obtained in this study could supply a piece of anatomical information to the investigators and furnish a useful reference to the orthopaedist or neurosurgeon in their treatments for the Chinese or Indian patients with spinal stenosis problems.
