The operational meaning of maturity criteria

The fact that specific radiographic criteria represent different proportions of attained maturity in males and females, in individuals of different geographical origin, in undernourished as opposed to over-nourished subjects and in genetic or chromosomal extremes together indicates the operational complexity of “skeletal maturity” and indicates the need to separate those aspects of skeletal development that are not sex-hormone dependent from those whose timing is directly dependent upon gonadal status.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/37515/1/1330350304_ftp.pd

Magnitude of sex differences in dichotomous ossification sequences of the hand and wrist

Among the dichotomous (present/absent:absent/present) ossinication sequences individually ascertained in 3059 boys and girls with at least one but not more than 27 ossification centers of the hand and wrist, 54 such sequences exhibit statistically-significant sex differences in frequency, 32 of them at the 1% confidence level or better. Analyzed by regions (rows and rays, epiphyses and round bones), ten centers, primarily distals and those of the first digit, account for the majority of the significant sex differences.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/37551/1/1330420111_ftp.pd

A simple technique for eliminating tracheal buckling on lateral neck roentgenograms

Brief, gentle extrinsic pressure on the trachea at the level of the cricothyroid membrane during lateral roentgenography of the neck is suggested as a safe, simple, and reliable means of evaluating the retrotracheal pre-cervical soft tissues in infants and children.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46690/1/247_2004_Article_BF00972851.pd
