The objective of this investigation was to compare the accuracy of mandibular measurements using a stabilizer (MS) with gold standard computed tomography (GS) images. Sixty mandibles were studied. Werth TomoScope HV Compact® was used to obtain CT images (GS), and the MS was also used. Analysis of the CT scans was performed using the VG Studio Max software® (Volume Graphics GmbH, Heidelberg, Germany), and MS was used after the proper positioning of the mandible. Descriptive and paired t test measures were used, and a ROC curve was calculated, as well as sensibility and specificity. MedCalc and STATA 13.0® were used (95% level of significance). Bicondylar breadth, bicoronoid breadth and minimum ramus breadth reached the highest concordance correlation coefficients at 0.99 (0.99-1.00), 0.99 (0.99-1.00) and 1.00 (0.99-1.00), respectively. Comparing observers with GS, the lowest accuracy was noted for the maximum mandibular length

“…Both morphological and metric analyses were employed, and where possible, South African standards were utilised (e.g. Steyn & Işcan, 1999;Asala, 2001;Patriquin et al, 2003). The age distribution for the complete sample was standardised by following the guidelines provided by Falys & Lewis (2011).…”

Since the arrival of Dutch colonists in the Cape of Good Hope, South Africa, Khoesan populations were subjected to severe political and economic marginalisation and often fell prey to racial conflict. These circumstances persisted until the early 20th century, during which an astonishing number of Khoesan skeletons were transported from South Africa to various locations in Europe, as at the time, different institutions competed to obtain these remains. The purpose of this study was to assess the health status of the late 19th and early 20th century Khoesan. Skeletal remains housed in two different European institutions were studied. The sample comprised 140 specimens from the Rudolf Pöch Skeletal Collection in Vienna, Austria, and 15 specimens from the Musée de l'Homme in Paris, France. These individuals represent both sexes and were aged between newborn and 75 years, with 54 being younger than 20 years of age. Results indicated high levels of typical disease conditions associated with groups under stress, such as periostitis, cribra orbitalia and porotic hyperostosis. Treponemal disease, rickets, osteoarthritis and trauma were also encountered amongst other more specific indicators of health and disease. This study provided additional knowledge on the health status and lives of the Khoesan people during this turbulent period and created new awareness regarding a group of severely mistreated individuals.

“…For instance, gender-based differences in pelvic and sacral morphology are well-documented (Tague, 1992;Patriquin, Loth, & Steyn, 2003;Tague, 2005), possibly influencing lumbopelvic sitting postures and related functional tissue adaptations. Other gender-based anthropometric differences could also exist that may influence lumbo-pelvic sitting postures and/or flexibility.…”

Understanding factors that influence preferred sitting postures is considered important to prevent low-back pain (LBP) associated with seated exposures. The purpose of this study was to examine the influence of gender and flexibility (hip, hamstring, and low-back) on lumbo-pelvic postures adopted when performing laboratory-simulated computer work and automobile driving. Ten female and 9 male volunteers were exposed to 10 minutes each of the abovementioned sitting conditions. Sagittal lumbo-pelvic kinematics were recorded during each sitting condition. Correlation analyses were performed between lumbo-pelvic postures and various measures of hip, hamstring, and low-back flexibility. When driving, females exhibited 9.8 degrees more posterior pelvic tilt (p = 0.0329) and 10.5 degrees more lumbar flexion (p = 0.0116) than males with respect to their lumbo-pelvic alignments in upright standing. When performing seated computer work, it was males who experienced greater posterior pelvic tilt (p = 0.0048). Individuals with greater hip flexibility, typically females, adopted lumbar flexion postures closer to their voluntary end-range while driving (r = 0.5709; p = 0.0107). Individuals who exhibited greater posterior pelvic tilt in office chair sitting, typically males, were those with less hip (r = -0.5484; p = 0.0150) and hamstring (r = -0.4690; p = 0.0496) flexibility. Given that differences exist between males and females with respect to various indices of hip, hamstring, and low-back flexibility, it is possible that gender-based differences in seated postures are related to inherent differences in flexibility between the sexes. These findings suggest that strategies to prevent LBP associated with sitting may depend on both individual flexibility characteristics and the type of seated exposure.
