“…Previous studies have used roughness parameter Ra (root mean square method) to determine roughness for the articular cartilage surfaces of various equine synovial joints to assess fractal dimensioning of surface features during drying (Smyth, Rifkin, et al, 2014; Smyth, Rifkin, et al, 2012). The mammillary processes observed in the present study had a degree of fractal dimensioning, and the scale for analysis was determined by scale of interest (macro‐scale) and instrument resolution (Perrone Jr & Williams, 2019).…”

“…It is possible to obtain higher resolution with the NextEngine HD laser scanner, but for this study we can only claim the results of average height and periodicity of mammillary processes for animals that were 120‐days and older in age. Measurements of <0.1 mm could be the result of noise in the scanning process (Perrone Jr & Williams, 2019).…”

“…The proximal end of 20 porcine femurs ranging in age from 9‐days preterm to 900‐days old were scanned with a high‐definition (HD) laser scanner following a previously developed protocol (Perrone Jr & Williams, 2019). A total of 33 femurs from domestic pigs aged 9‐days preterm ( n = 2), 2‐days old ( n = 6), 20‐days old ( n = 4), 35‐days old ( n = 4), 120‐days old ( n = 8), 365‐days old ( n = 1), 540‐days old ( n = 2) and 900‐days old, ( n = 6) were obtained.…”

“…All bones had similar gross anatomy within their respective age groups, as judged qualitatively, such that one bone from each group was an adequate gross anatomical representation of the entire group, except for the 365‐day old where there was only one available femur. Biomodels of one femur from each age group were generated from HD laser scans of the epiphysis (when possible) and metaphysis, capturing surface features as small as 0.1 mm (Perrone Jr & Williams, 2019). All femurs for the 120 ( n = 8) and 900‐day old ( n = 6) groups were scanned for statistical purposes.…”

“…Statistical comparisons between age groups were limited to the 120‐ and 900‐day old groups due to an insufficient sample size for the 365‐ and 540‐day old groups. For ages 35 and younger, analysis showed some of the surface features were below the manufacturer's stated resolution limits of the scanner and could be considered noise, though it may be possible to achieve better resolution than the manufacturer's stated dimensional accuracy of the scanner (Perrone Jr & Williams, 2019).…”

The capital femoral physis is a growth plate located between the head of the femur and femoral neck, which forms a temporary joint where growth plate cartilage is converted to bone by endochondral ossification. The bone‐cartilage‐bone interface develops a unique radial pattern of interdigitating mammillary processes that interlock the femoral head with the metaphysis, increasing biomechanical stability. The arrangement of these mammillary processes may not be a random occurrence and likely serves to provide mechanical mechanisms to enhance biomechanical stability. In this study, we provide a qualitative and quantitative analysis of porcine femoral head mammillary processes and focus on the analysis of six key points of development: the epiphyseal tubercle, epiphyseal cupping, growth plate slope angles, expansion of the epiphyseal subchondral bone plate, epiphyseal elongation, and the emergence of smaller, radially arranged mammillary processes. We introduce a metric of surface roughness analysis to quantify mammillary processes and apply it to analyze the development of the observed radial pattern of peripheral mammillary processes from birth to adolescence. We hypothesized that these processes develop to form a radial pattern with some degree of periodicity beginning relatively early in development of the joint and increase in prominence with age and weight of the animal. These findings may have important implications in the early diagnosis and treatment of the hip disorder slipped capital femoral epiphysis (SCFE). Underdevelopment of femoral head mammillary processes may reduce joint stability and could be a risk factor in SCFE.

The modern practice of forensic anthropology is focused on the quantification of skeletal variation based upon a qualitative prowess developed according to theory and method in the parent discipline of biological anthropology. Such morphological variances allow estimates of biological attributes, for example, age, sex, population affinity, stature, pathology of disease processes-among others, that collectively may resolve the identification of unknown forensic human remains.The latter is a basic human right under International Humanitarian Law (IHL), and International Human Rights Law (IHRL) afforded to descendants who go missing in armed conflicts and other violence-base situations. The specific traditional methods applied by the forensic anthropologist are well established in the published literature and routinely supported by global research that guides graduate programs designed to train the next generation of practitioners. Important in that cornerstone literature and graduate training regimen are aspects of our practice that are increasingly cross-disciplinary, especially those grounded in the molecular, chemical, and histological sciences. These upper-tier endeavors supplement and many times, validate, the traditional approaches as dictated by case context. This review focuses on evolving cross-disciplinary developments and novel research trends in the analysis of human remains that involve the specific expertise of the forensic anthropologist.
