[The changes in bone mineral content in experimental limb lengthening].
The results of bone mineral content measurement in experimental limb lengthening are reported. The results demonstrated that in the restoring process, both the strength and the stiffness of the lengthened bone are positively correlated to the relative bone mineral content with coefficients of correlation 0.59 (P < 0.001) and 0.85 (P < 0.001) respectively. Analyses of curve fitting showed that the strength is directly proportional to the 1.7479 th power of bone mineral content and the stiffness to its 2.05842 th power Hence, the authors consider that bone mineral content measurement could be used as a noninvasive index for monitoring the changes of bone strength and stiffness during recovering process of bone lengthening.
