Aparelho deThomas modificado associado ao pino intramedular na osteossíntese de tibiotarso em cacatua (Cacatua galerita)

Abstract

In spite of the existence of different methods of reduction of fractures already mentioned in birds, the choice of the ideal technique, factors such as the size and age of the birds, the time past since the break, the healing and the presence of intercurrent problems must be considered. In this context, the present study aimed to describe a case of surgical treatment of a broken tibiotarsus in a cacatua by using reduction with intramedular pin with a modified Thomas device as a method of external setting. The absence of suggestive clinical sign of circulatory involvement in the site of the break, such as edema, cyanosis and necrosis associated with the ease of movement indicated that the type of immobilization used with the Thomas crutch was appropriate. The intramedular pin method with the modified Thomas device allowed satisfactory stability to the focal point of the fracture. Adjusted formation of the bone callus shown by the clinical signs and x-rays examinations was considered efficient in the reduction of the fracture of the tibiotarsus in the cacatua.
