Abstract:
To observe the local microcirculation changes in primary bone lengthening for gunshot bone defect treated by external fixators, the experimental study was carried out by using canine model of gunshot bone defect of extremities. 16 mongrel dogs were randomly divided into 2 groups, external fixators were used to distract early callus in one group and plaster was used for immobilization in the other group. The local microcirculation in the two groups was measured. The results showed: (1) Different from the normal fractures, the local blood flow of gunshot fractures was reduced in the first 3 days and then increased, at the 6th week it was close to the normal level. (2) There was no significant difference in the restoration of blood flow between the groups of external fixation and plaster immobilization. It is suggested that primary bone lengthening for gunshot bone defect by external fixators has no adverse effect on the restoration of the local blood flow.
