Abstract:
[Objective]To explore the effects of axial stress regulation on healing of lengthened callus.[Method]Tibiaes of 40 rabbits divided into 2 groups were lengthened with circular external fixator.X-ray bone density and histology tests were performed.[Result]The X-ray showed lengthened callus was different after operation.In the control group,lengthened center had a serial callus and cortex had not formed,in the experimental group lengthened center had serial cortex and ttransfixial medullary cavity expects serial callus.[Conclusion]Axial stress regulation and periodicity continue to shortened micromovement stress may promote healing after bone lengthening.
