[Use of densitometric measurements for evaluation of bone regeneration in lengthening of the long bone shaft].

A series of 18 long bone lengthenings in 16 children has been analyzed. To assess new bone formation sonography, DEXA and computerized tomography have been employed. Sonography proved to be most useful for elongation monitoring, but densitometry delivered most data concerning quantity and distribution of the new bone formation especially during stabilization stage. DEXA combined with CT allowed for making decision of the removal of ilizarov apparatus.
