استفاده از روشي جديد براي درمان شكستگي استخوان بازوي كبوتر

Various traditional and innovative forms of fracture fixation have been applied in birds orthopedic. The purpose of this study was to compare the applicability of the stainless steel intramedullary (IM) pin and IM pin made from ovine and canine bone. Ovine and canine long bones were used to prepare pins in appropriate size and dimension. The pins were packaged and sterilized. Forty domestic pigeons (with 390 gr average body weight) were divided into 4 equal groups, pigeons were anesthetized and humeral bone was cut by orthopedic saw. In first group the fracture bone was not treated. The stainless steel pins were inserted into the humeral medulla in the second group of pigeons, in the third and forth groups prepared pins from ovine and canine bone were in serted into the medulla. After 32 weeks the pigeons of the first group were not able to fly, in the second group pigeon had imbalance in flight, in the third and forth groups the pigeons were able to fly with no problem. Radiographically there was not a significant differences between 2nd, 3rd and 4th groups, but there was a significant difference between the first group and other groups (P<0.001). Non of the bone pins were rejected, all were absorbed in later stages in large quantities. It was concluded that bone pin made from canine and ovine bone were compatible with the stainless steel pins in providing rigid stability as well as having the advantage of gradual resorption and no interference with flying condition.
