Differences in calcium accumulation between human plantar and palmar aponeuroses.
To elucidate the characteristics of calcium accumulation of human plantar and palmar aponeuroses, the authors determined the calcium content of human plantar and palmar aponeuroses by atomic absorption flame emission spectrophotometry. The subjects consisted of 9 men and 14 women, ranging in age from 61 to 93 yr. In the plantar aponeurosis, the calcium content was significantly higher in the anterior and posterior parts than in the middle part. It is known that pressure distribution under the sole of a foot is higher in the anterior and posterior parts than in the middle part. The present study suggests that the accumulation of calcium in the plantar aponeurosis is related with the pressure distribution under the sole of a foot. The calcium content increased progressively with aging in the anterior part of the plantar aponeurosis, but not in the middle and posterior parts. Regarding the palmar aponeurosis, the calcium content was significantly higher in the anterior and posterior parts in comparison with the middle part. It was found that the calcium content increased progressively with aging in the posterior part of the palmar aponeurosis, whereas it did not increase significantly with aging in the anterior and middle parts. Regarding the relationship between the calcium content of the aponeuroses and the bone mineral density, a significant correlation was found between the calcium content in the anterior part of the palmar aponeurosis and the bone mineral density of the scaphoid bone.
