“…On the other hand, many researchers (Jankauskas, 1994;Kacar et al, 2016;Siemionow et al, 2011;Snodgrass, 2004;Watanabe and Terazawa, 2006) revealed significant statistical correlation for age and many measurements of different vertebrae. These correlations were due to the effect of vertebral degenerative changes, which is different from this study.…”

Background: Identification of bony remains and other decomposed parts of human is of great importance not only for legal but also for humanitarian reasons. However, in certain instances due to burial factors or in cases of explosion disasters, many of large bones may be destroyed or incomplete. For age and sex identification, vertebrae aren't well studied; however, many vertebrae showed high accuracy rates for sex identification. Methodology: One hundred and twenty-three Egyptian patients were included in the current study; 62 were females and 61 were males (age from 10 to 64 years). Abdominal Computer tomography (CT) scans were done for those patients in the Department of Radiology in kasralainy faculty of medicine, Cairo University after they gave informed consent. Fifteen linear measurements were taken for the first lumbar vertebra (L1) to assess age and sex. Results: Male patients showed larger mean values most of measurements of the first lumbar vertebra than females and sex was determined at accuracy rate of 84.6%. Moreover, significant correlation was found for age and majority of measurements; but unfortunately it was weak correlation. Conclusion: Sex can be estimated from first lumbar vertebrae with reasonable levels of accuracy in legal and humanitarian situations when skeletal remains are incomplete. However, it seems that vertebral measurements of lumbar vertebra aren't useful indicator for age estimation with further studies needed on larger samples and on different age groups.

Introduction: Accurate sex estimation plays a very important role in determining the identity of unknown individuals. Age determination also has become increasingly important in forensic science for both living and remains. Vertebrae are one of the least studied bones for age and sex identification; however, its presence at a death scene is the most common of all. The 12 th thoracic vertebra (T12) is easily identifiable in a disarticulated skeleton, due to its unique morphology. Identification depending on radiological techniques is an emerging valuable tool in forensic science field.

“…Watanabe and Terazawa [37] stated that the marginal osteophyte on the vertebral bodies began to form around the age of 30 in both sexes. Differences between individuals owed to a response to erect posture during bipedal locomotion rather than differences in occupational stress [38].…”

The aim of this study was to characterize the individuals with sacroiliac joint bridging (SIB) by analyzing the degenerative changes in their whole vertebral column and comparing them with the controls. A total of 291 modern Japanese male skeletons, with an average age at death of 60.8 years, were examined macroscopically. They were divided into two groups: individuals with SIB and those without bridging (Non-SIB). The degenerative changes in their whole vertebral column were evaluated, and marginal osteophyte scores (MOS) of the vertebral bodies and degenerative joint scores in zygapophyseal joints were calculated. SIB was recognized in 30 individuals from a total of 291 males (10.3%). The average of age at death in SIB group was significantly higher than that in Non-SIB group. The values of MOS in the thoracic spines, particularly in the anterior part of the vertebral bodies, were consecutively higher in SIB group than in Non-SIB group. Incidence of fused vertebral bodies intervertebral levels was obviously higher in SIB group than in Non-SIB group. SIB and marginal osteophyte formation in vertebral bodies could coexist in a skeletal population of men. Some systemic factors might act on these degenerative changes simultaneously both in sacroiliac joint and in vertebral column.
