“…The work presented by Khanpetch et al [15] could not be implemented as it was based on metacarpal features such as bone widths and diameters, which could not be approximated from our feature set. The work presented by Amayeh et al [7] could not be replicated due to the complexity of the extracted features.…”

“…In [15] the authors also analysed the use of hand features obtained from metacarpals hand bones, but including a wider set of features: total length and mid-diameter of each bone, as well as width and height of both bone ends. These measures were taken separately from both the right and left hand, and a complete set of measures were obtained for 196 subjects (118 males, 78 females).…”

Understanding the relationship between physiological measurements from human subjects and their demographic data is important within both the biometric and forensic domains. In this paper we explore the relationship between measurements of the human hand and a range of demographic features. We assess the ability of linear regression and machine learning classifiers to predict demographics from hand features, thereby providing evidence on both the strength of relationship and the key features underpinning this relationship. Our results show that we are able to predict sex, height, weight and foot size accurately within various data-range bin sizes, with machine learning classification algorithms out-performing linear regression in most situations. In addition, we identify the features used to provide these relationships applicable across multiple applications.

RESUMEN:Los huesos metacarpianos son largos y cilíndricos, articulándose proximalmente con el carpo y distalmente con las falanges proximales de los dedos. Estos huesos han recibido especial atención en el área de la medicina forense para la determinación del sexo. Con el objetivo de aportar datos biométricos sobre los huesos metacarpianos en individuos chilenos, determinamos radiográficamente, en 52 manos de individuos de ambos sexos, la longitud de cada uno de ellos, el ancho de su base, cuerpo y cabeza. En los individuos de sexo masculino, la longitud promedio del I metacarpiano fue de 40,9 ± 6,4 mm y la del II metacarpiano de 60,8 ± 7,4 mm; en el sexo femenino el I metacarpiano tuvo un promedio de 39,2 ± 5,2 mm y el II metacarpiano de 60,6 ± 8,9 mm. El ancho promedio de la epífisis proximal de cada hueso metacarpiano en individuos de sexo masculino fue para el I metacarpiano 12,5 ± 2,1 mm y para el II metacarpiano 14,8 ± 2,1 mm; en el sexo femenino, el I metacarpiano tuvo 11,6 ± 2,3 mm y el II metacarpiano 13,9 ± 2,1 mm. El diámetro promedio en la parte media del cuerpo de cada hueso en individuos masculinos fue para el I metacarpiano 11,8 ± 2,2 mm y para el II metacarpiano 11,7 ± 2,2 mm; en el sexo femenino, el I metacarpiano tuvo 10,86 ± 2,8 mm y el II metacarpiano 11,8 ± 2,6 mm. El ancho promedio de la epífisis distal de cada hueso en los individuos de sexo masculino fue para el I metacarpiano 6,7 ± 1,2 mm y el II metacarpiano de 5,7 ± 1,2 mm; en el sexo femenino, esta variable fue para el I metacarpiano 6,2 ± 1,5 mm y para el II metacarpiano de 5,0 ± 1,4 mm. El primer metacarpiano es el más corto de todos. El segundo metacarpiano siempre tuvo una longitud mayor que los otros metacarpianos, especialmente del tercero, que le sigue en longitud. En solo un caso la longitud del segundo metacarpiano fue menor que la del tercero y en dos casos el segundo y el tercer metacarpiano tuvieron la misma medida. El tercer metacarpiano siempre fue de mayor longitud que el cuarto. Estos resultados son una contribución al conocimiento de los huesos metacarpianos de nuestra población, pudiendo ser utilizados tanto en medicina forense como en el área traumatológica.PALABRAS CLAVE: Anatomía; Mano; Huesos metacarpianos. INTRODUCCIÓNEl esqueleto del metacarpo está compuesto de cinco huesos cilíndricos. Estos huesos articulan proximalmente con el carpo, y distalmente, con las falanges proximales de los dedos. Con la mano en posición anatómica se numeran de lateral a medial. El primer metacarpiano es el más corto y parece una falange, pero los demás son de similar apariencia. El segundo metacarpiano es el más largo y el tercero, cuarto y quinto son gradualmente más cortos. En general cada uno de estos huesos tienen una base, un cuerpo y una cabeza (Tountas & Bergman, 1993).Estos huesos han recibido atención especial en el área de la medicina forense para la determinación del sexo, asi como otros huesos (clavícula, esternón, costillas, patella, huesos tarsianos, metatarsianos, falanges) han sido utilizados con estos fines.

“…Preferred measurements for the metacarpals vary among the subfields within biological anthropology (e.g. Susman, 1979;Trinkaus, 1983;Hershkovitz et al, 1986;Lazenby, 1994;Stojanowski, 1999;Khanpetch et al, 2012) and even from study to study in similar subfields, hampering comparison of results (e.g. Musgrave and Harneja, 1978;Susman, 1979;Falsetti, 1995;Smith, 1996;Barrio et al, 2006).…”

Standards for measuring the metacarpals are absent from commonly used osteometric guides. Perhaps the closest to a set of standard measurements in common use today are those proposed by Scheuer and Elkington (Scheuer and Elkington: J Forensic Sci 38 (1993) 769-788) for forensic sex assessment. They include caliper measurements of interarticular length, base and head width, base and head height, and maximum midshaft diameter. Over the last decade, a new set of measurements that encompass similar dimensions to those used by Scheuer and Elkington, but which are taken with a mini-osteometric board (MOB) have been developed by the lead author. Use of the MOB avoids the need to manipulate both the bone and calipers in three-dimensional space and causes less strain on the hands. However, the question of intra- and interobserver accuracy has not been adequately addressed for either set of measurements. The purpose of this study was to test both the Scheuer/Elkington and MOB measurements on 20 hands from 10 anatomical skeletons for intra- and inter-observer accuracy. The study found that 92% of the MOB measures had a lower intraobserver error, and 88% had a lower interobserver error than did the caliper measurements. It also found that the maximum midshaft diameter measurement used by Scheuer and Elkington is more repeatable than a mediolateral diameter. Overall, 88% of the 25 MOB measurements had median intraobserver error rates of under 1.5%, compared with 60% of the caliper measurements. Furthermore, the MOB measurements as a set were taken 10 to 12% faster than the caliper measurements.
