2005. MACROSCOPIC STRUCTURE OF BONE CALLUS AFTER USING EXTERNAL FIXATOR MACZEK IN SHEEP, EJPAU 8(3), #27.

ABSTRACT

The studies were carried on 30 black-headed sheep. The sheep were divided into three equal groups. External fixator Maczek mini was used in all groups. In group I fixation with bone fragment pressure was applied, in group II – fixation without pressure and in group III – dynamic-axial fixation. After three months of observation, all sheep were subjected to euthanasia. Callus samples were taken to prepare longitudinal osseous microsections. An analysis of 30 profiles and osseous longitudinal microsections from three group of sheep shows a proper course of ossification in the majority of animals from groups II and III, however callus of poorer quality was observed in some animals from group I.

Key words: sheep, external fixator Maczek, bone callus.
