Determination of sex from the proximal hand phalanges in a Thai population

Six new examples of the bipartite trapezoid bone: Morphology, significant population variation, and an examination of pre-existing criteria to identify bipartition of individual carpal bones

“…individuals of known identity who had died in the Chiang Mai region in northern Thailand since 1990 (Mahakkanukrauh et al, 2013). Additional trapezoids were examined from the Early-Mid Holocene archeological site of Gobero, located in the Republic of Niger (Sereno et al, 2008;Stojanowski, 2013).…”

Sex estimation from upper limb bones in a Thai population

“…Therefore, it is crucial to derive the population-specific reference data in each population to increase the accuracy of sex estimation. In Thailand, although several studies have been reported in sex estimation using Thai skeletal remains, such as humerus [4], cranial and appendicular bones [13], sternum [14], vertebral column [15], radius [16], calcaneus [17,18], mastoid process [19], metacarpal bone [20], iliac bone [21], proximal hand phalange [22], talus [23], navicular bone [24], skull [25], sternum [26], maxillary suture [27], scapula [28], and os coxa [29]. However, studies of sex estimation from fragmented upper limb bones have rarely been published.…”

Sex determination using proximal hand phalanges

“…Finally, a recent study on a Thai population of 249 individuals provided discriminant function equations for sex assessment. Correct classification rates ranged from 87.6% to 92.3%, with left 1st proximal phalanges presenting the highest accuracy (92.3%), followed by the left 2nd proximal phalanges (91.9%) [21].…”

“…Concerning proximal hand phalanges, however, there are few researches investigating sex determination. Among them, some utilize multiple functions from all ten proximal hand phalanges [4,6] while others focus on specific phalanges or phalangeal dimensions [3,5,21]. Due to the fact that most functions selected vary among studies, a direct comparison was rarely possible.…”
