[Radiographic research on skeletal measurements and morphology of the normal hand of the Japanese. Part Two: Child (growth stage)].

The present investigation was undertaken to develop a standard method of recording the bone measurements of the normal hand for use in comparative studies of genetic abnormalities of the skeletal system affecting the hand. The data for this study were obtained from the radiographs of the hand of normal 428 males and 393 females between ages of 1 and 19 and in the 20s. Length and width of all the phalanges and metacarpals were recorded. The phalangeal index and metacarpal index of each bone were obtained by dividing the length by the width. Frequencies of brachymesophalangy of the small finger and brachytelephalangy of the thumb and pseudoepiphysis of the 2nd metacarpals were investigated. No significant difference was noted between the bones of the right and left hand. Based on these results, the development of finger bone during normal growth of healthy infants are clearly delineated.

[Radiographic research on skeletal measurements and morphology of normal hand of Japanese. Part One: Adult].

The present investigation was undertaken to develop a standard method of recording the bone measurements of the normal hand for use in comparative studies of genetic abnormalities of the skeletal system affecting the hand. The data for this study are obtained from the radiographs of the hands of normal 461 males and 565 females aged from 20 to 84 years. Measurements of length and width of all the phalanges and metacarpals are recorded. The phalangeal index and metacarpal index of each bone are obtained by dividing the length by the width. Frequencies of brachymesophalangy of the little finger and brachytelephalangy of the thumb are investigated. There are no significant differences between the bone of the right and left hand related to hand dominance. The radiographs of the hands of mother and son with the Marfan syndrome were compared with normal one. Metacarpal index and phalangeal index are useful for diagnosis of the Marfan syndrome.
