[Bone maturity evaluation by automatized metric measurements].
OBJECTIVE
Precision and rapidity of computerised procedures facilitate bone maturity evaluation by measuring bone images. In this paper we analysed the adequacy of several of these measures to evaluate growth or bone maturity.


METHODS
To determine growth or maturity indicating parameters, two hundred X-rays of the left hands and wrists of 2 to 18 years old children were examined by an automated image analysis procedure (IMAGO-2). Children were examined every six months (18 to 36 months) obtaining several auxological data (weight, height, bone maturity, TW2 methods, etc.). The relationship between the automated indicating parameters of maturity or growth and the auxological data were studied (linear correlation and multiple regression).


RESULTS
All parameters correlate with the chronological age. The area parameter presents the highest coefficient of correlation with weight and Speed of Growth. The perimeter presents the best correlation with Height and bone maturity (TW2). Variations in some separation measurements from the circular ones relate well with auxological data changes.


CONCLUSIONS
It is difficult to categorically catalogue one measurement as the only and exclusive indicator of maturity or growth. The studied parameters correlate best with bone maturity (TW2) when compared with those of the auxological data (weight, height) which could indicate their usefulness to evaluate bone maturity.
