As fraturas de ossos longos correspondem a episódios traumáticos, muito frequentes em
clínica de animais de companhia, sendo acompanhadas por um conjunto de alterações locais e
sistémicas no doente, com repercussões no hemograma.
A partir do nosso estudo retrospetivo, tentaremos demonstrar a existência de uma relação
entre as alterações que ocorrem nos diferentes constituintes do hemograma numa fratura
traumática dos ossos longos e a gravidade das mesmas. Para isso, este estudo foi dividido em
2 objetivos:
Primeiro, avaliar casos de fraturas de ossos longos que deram entrada no HEV, caracterizando
o sexo, a idade e peso do animal; bem como a etiologia, a localização do osso relativamente
ao esqueleto apendicular (úmero, rádio/ulna, fémur, tíbia/fíbula), a localização da fratura
relativamente ao osso (proximal, diáfise, distal), o tipo e a gravidade da fratura.
Segundo, avaliar as alterações no hemograma destes animais, correlacionando-as com a
gravidade e tipo de fratura.
A amostra foi composta por um total de 30 canídeos (Canis familiaris) (N=30), com fraturas
nos ossos longos. Considerámos 3 grupos de doentes de acordo com o seu peso vivo: pequeno
porte (<10kg), médio porte (10-22kg) e grande porte (>22kg). Relativamente ao sexo foi
possível verificar que os machos apresentaram a maior prevalência de fraturas (63%);
relativamente à localização, a mais frequente foi ao nível da diáfise (40%). As fraturas do
rádio/ulna foram as mais frequentes (40%), seguidas pelas fraturas do fémur com 26,7%, da
tíbia/fíbula com 23,3% e do úmero com 10%; tendo afetado maioritariamente os animais de
pequeno porte (66%). A etiologia mais prevalente foi a queda (41%).
De acordo com os resultados obtidos foi possível concluir, para a amostra estudada, que não
existiram alterações do hemograma consoante a gravidade da fratura.
ABSTRACT - Long bone fractures are a common injurie in the small animal clinic and are often accompanied by a set of local and systemic changes. Some of these changes are expressed in the constituents of the hemogram. The present retrospective study aimed to evaluate the relationship between the changes that occur in the different hemogram parameters at the time a traumatic long bone fracture happens and the severity of that fracture. For that, this study was divided in 2 goals. The first goal was to evaluate cases of long bone fractures assisted in HEV; determining the sex, age and weight of the animal; as well as the cause, location of the bone in the appendicular skeleton (humerus, radio/ulna, femur, tibia/fibula), the location of the fracture in the bone (proximal, diaphysis, distal), the type and severity of the fracture. The second goal was to evaluate changes in the hemogram establishing a correlation between them and the severity and type of fracture. This sample was made by 30 animals from Canis familiaris species (N=30) which presented fractures on the appendicular skeleton. There were considered 3 groups of patients according to their weight: small size (<10kg), medium size (10-22kg) and large size (>22kg). Regarding the sex it was possible to verify that males presented the highest prevalence of fractures (63%). Regarding the location, the most frequent occurred in the diaphysis (40%). The most common fractures were located in the radio/ulna (40%), followed by femoral fractures with 26,7%, tibia/fibula fractures with 23,3%. and humeral fractures with 10%; the small breeds were the most affected (66%). The fall was the most prevalent cause (41%). In this study, according with the results, it was possible to conclude that there were no hemogram changes when related with the fracture severity.
