Abstract
BackgroundCallotasis has become an established option for reconstruction of congenital anomalies and after resection of bone tumors. However, fracture after removal of the lengthener remains one of the most serious complications. Mathematical morphology is an image processing technique that allows the skeletal patterns of trabecular bone to be selectively extracted as binary images from computed radiographic (CR) images. We evaluated the strength of the lengthened callus by analysis using mathematical morphology and examined the utility of this method in a biomechanical study. MethodsThree Japanese white rabbits per time point were euthanized at the 2-, 3-, 4-, 6-, and 8-week points after completion of the lengthening and were evaluated by CR images and analysis with mathematical morphology. ResultsThe changes of the number and continuity of trabecular bone were obtained visually and could be evaluated quantitatively. In some cases corticalization appeared to be complete in the CR images, but it was not complete on the morphological images. Such cases were found to be weaker than those in which corticalization appeared to be complete on both CR and morphological images. ConclusionAnalysis with mathematical morphology is useful for evaluating the lengthened callus after callotasis.
