Pino ósseo homólogo conservado em glicerina a 98% e hemicerclagem com fio poliglactina 910 na osteossíntese umeral de pombos domésticos

The objective of the present study was to evaluate the use of a homologous bone intramedullary pin, conserved in glycerin at 98% associated to hemicerclage with a thread of polyglactina 910 in the transverse humerus osteosynthesis of domestic pigeon (Columba livia). The distal part of the tibialtarsus, conserved with bone marrow, was used as a bone pin. Twenty domestic pigeons were operated, adults, no sex distinction, clinically healthy. Those animals were separated randomly in five groups, with four individuals. The humerus was transversely split up surgically in its diaphysis and the bone pin, properly implanted in the sinus of the bone. Holes were accomplished and through them it was possible to proceed the hemicerclage in Wolff suture form with polyglactina 910. The animals were evaluated clinically through weekly x-rays and histologically after periods of 15, 30, 60, 90 and 120 days. The conservation of the bone pin in glycerin at 98% was evaluated through microbiological exams. In all the animals, clinically can be noticed excellent adaptation concerning the surgery and normality of the use of the member, and radiologically, bone callus formation and cicatrization of the fracture can be observed. Histologically, it is observed bone callus formation 15 days after the surgery and cicatrization with complete remodeling from 90 days. In that exam, besides light to moderate inflammatory reaction in the initial period of evaluation, no other event was diagnosed in the subsequent periods. It was concluded that the technique and used materials become a highly viable option in the humerus transverse osteosynthesis of domestic pigeons.
