Experimental study of leg lengthening by epiphyseal distraction



Experimental study of leg lengthening by epiphyseal distraction



Journal of Kyoto Prefectural University of Medicine 97(10): 1271-1287



We have produced an experimental model for lengthening lower limbs using a distraction device to apply tension to the epiphyseal growth plate and to produce temporary epiphysiolysis, and also an experimental model to attempt lower limb lengthening by continuously applying a specific distraction force to the epiphyseal growth plate; the effects of these experimental models on the longitudinal growth of lower limbs have been investigated. In experiment 1, distraction force was applied to the epiphyseal growth plate of the left proximal tibia of juvenile domestic rabbits, for two weeks and then released. In experiment 2, the distration device with a coil spring wes fitted to the left proximal tibia in a similar fashion, with distraction force being continuously applied to the epiphyseal growth plate through a single 1.5 mm diameter Kirschner wire inserted in the diaphysis and the epiphysis of the proximal tibia. Coil springs producing forces of 1 kg, 2 kg, 3 kg, and 4 kg were used. In experiments 1 and 2, soft X-ray pictures were taken of the left tibia and fibula immediately after operation, and then again after 1 week. In experiment 1, lower limb lengthening by epiphysiolysis was observed in the early stages, but epiphysiolysis subsequently occurred, resulting in limb shortening. Histologically, the epiphyseal plate exhibited premature epiphyseal arrest. Maximum lower limb lengthening by epiphyseal distraction was 3.3 mm with a force of 3 kg, representing a 2.43% increase compared with the contralateral control side. In lower limb lengthening by epiphyseal distraction, no premature epiphyseal closure or other histological abnormalities were noted. These results suggest that the lower limb lengthening by epiphysiolysis is clinically effective, when it is applied just before the epiphyseal closure. On the other hand, lower limb lengthening by epiphyseal distraction is rather easy and gives better lengthening results in comparison with the conventional method. The epiphyseal distraction is considered clinically effective in the adjustment of lower limbs which are in the process of developing.
