Bony changes on the superior distal surface of the metatarsals and the superior proximal surface of the first proximal foot phalanx are described in a prehistoric skeletal sample from Coastal Ecuador. The location and morphology of the alterations, as well as their association with femoral "squatting facets" strongly suggests they were produced by prolonged hyperdorsiflexion of the toes, probably resulting from habitual kneeling posture. Comparative data are presented from five other New World skeletal samples.
在厄瓜多尔沿海地区的一个史前骨骼样本中，描述了跖骨远端上表面和第一近节趾骨近端上表面的骨质变化。这些改变的位置、形态，以及它们与股骨“蹲踞面”的关联，强烈表明它们是由脚趾长期过度背屈造成的，可能源于习惯性跪姿。还展示了来自其他五个新大陆骨骼样本的对比数据。
