          Abstract

          The aim of the present study was to obtain the measurements of the different humerus segments and to estimate the length of humeri from them. For this purpose 100 (51 left and 49 right) sex-aggregated, adult dry humerus from Indian population, were taken to analyze the morphometric details of the humerus segments. The distance between five different segments viz: most proximal point of the humeral head and greater tuberosity (HA), head of the humerus and surgical neck of humerus (HB), proximal and distal point of olecranon fossa (HC), the distal point of olecranon fossa and trochlea of humerus (HD), proximal point of olecranon fossa and distal point of trochlea of humerus (HE) and finally the maximum length of humerus (HL) were obtained by means of an osteometrical board and an analogical caliper. Simples linear regressions (p < 0.01) were made to correlate each segment with the total length of the humerus. Positive results were obtained in segments HB and HE of right humerus. Regressions formulae were obtained to define these estimative. In conclusion, our study demonstrated that length of the humerus can be estimated from measures of different segments of humerus and this study helps in forensic, anatomic and archeological cases in order to identify unknown bodies and to determine stature of the individual and as well as for the orthopedic surgeons for the treatment of proximal and distal humerus fractures and for their reconstruction.

          El objetivo del estudio fue obtener las medidas de diferentes segmentos del húmero y calcular la longitud del húmero a partir de ellos. Fueron seleccionados 100 (51 izquierdos y 49 derechos) húmeros adultos secos, separados por sexo, de población india para analizar los detalles morfométricos de los segmentos dle hueso. La distancia entre cinco segmentos diferentes fueron establecidos: punto más proximal de la cabeza humeral y la tuberosidad mayor (HA), cabeza del húmero y cuello quirúrgico del húmero (HB), punto proximal y distal de la fosa olecraneana (HC), punto distal de la fosa olecraneana y la tróclea del húmero (HD), punto proximal de la fosa olecraneana y punto distal de la tróclea del húmero (HE) y, finalmente, la longitud máxima del húmero (HL) medidas obtenidas por medio de una tabla osteométrica y un caliper análogo. Se realizaron regresiones lineales simples para correlacionar cada segmento con la longitud total del húmero. Se obtuvieron resultados positivos en los segmentos de HB y HE de húmero derecho. Fórmulas de regresión se obtuvieron para definir estimativos. En conclusión, nuestro estudio demostró que la longitud del húmero puede estimarse a partir de las medidas de los diferentes segmentos del hueso, ayudando en casos forenses, anatómicos y arqueológicos con el fin de identificar cuerpos desconocidos o para determinar la estatura de la persona, así como a cirujanos ortopédicos para el tratamiento de las fracturas proximales y distales del húmero o para su reconstrucción.

            Application of osteology to forensic medicine.

            The four main features of biological identity are sex, age, stature, and ethnic background. The forensic osteologist aims to establish these attributes for an individual from their skeletal remains. Many techniques are available for the osteological determination of sex in the adult but it is one of the most difficult biological factors to ascribe to juvenile remains. Conversely, there are a multitude of markers to estimate age in the young skeleton but ageing becomes less accurate with increasing years. Stature is usually a relatively straightforward parameter to establish in the adult. In the juvenile, it is naturally correlated with age but is complicated by differences in rates of growth both between the sexes and between individuals. Determination of ethnic identity is the least reliable and is hampered by lack of data on many populations. This paper reviews the principal methods used to establish identity and comments on their reliability and accuracy in the forensic context. Copyright 2002 Wiley-Liss, Inc.

              Estimation of height from the length of long bones in a Portuguese adult population.

              Research was undertaken on 200 individuals (100 males and 100 females) from the northern districts of Portugal, all Caucasian, between the ages of 20 and 59. Height and bones were measured directly. Estimation of stature is obtained by applying a mathematical method based on a multivariable linear regression between the height of the cadaver and the lengths of humerus and femur. Humerus is measured on full length; femur is measured on both physiological and maximum lengths. Regression formulae and tables for males and females are produced for application in forensic anthropology when studying human skeletal remains. Comparisons are made between these tables and those of earlier authors, allowing us to verify important differences. One of the conclusions concerns the application of regression formulae based on some segment measurements. Due to the extremely high values of standard deviations, these may have no practical application.
