【 摘 要 】

The changes of reactive and/or destructive-and-reparative character, the degree of which depends on distraction parameters, have been revealed in articular cartilage during leg lengthening by the methods of scanning electron microscopy and histomorphometry analysis. The analysis of quantitative data has demonstrated, that autodistraction by 3 mm per day for 180 times (increment и 17 μm) appears to be less traumatic for the articular cartilage than manual distraction by 1 mm per day for 4 times, and, at the time, the period of experiment decreases significantly. The articular cartilage recovery occurs in the most intense manner in case of autodistraction with the same increment, but with the daily rate of 1 mm.
