The search for optimal distraction regimen is one of the main problems in limblengthening.
In this work we analyze results of limb-lengthening, performed in
automatic regimen at 60 patients with the use of originally developed device for highfractional
autodistraction. Two groups of patients were included in this study: Group I:
30 patients with limb-lengthening of humerus (16), tibia (19), femur (5) achieved with
the use of high-fractional autodistraction. Distraction was carried out on a twenty-four
hour basis with the mean speed 1.02 mm a day, with the distraction rhythm 120 a
day and means shear interval 0.009 mm. Group II: 30 patients with limb-lengthening
accomplished with the use of classicllizarov method (1 mm a day, 4 times daily). The
age distribution was comparable in both groups. Etiology of shortening was also
similar in both groups of patients, congenital shortening prevailed.In all patients
planned limb-lengthening from 4.5 cm to 10.0 cm (mean 6.5 cm) was achieved.
Within the 1st group index of fixation comprised 16,05+1,8, index of osteosynthesis
28,6±2,8. Within the 2nd group 20,27±4,2 and 38,2±6,5 respectively.Our
observations has showed that high-fractional autodistraction produce more favorable
conditions for adaptative and regenerative processes with significant shortening of
