Osteossíntese de fratura em colo femoral utilizando tomografia computadorizada e molde em 3D

Abstract

Fractures of the neck and femoral head constitute about 25% of femoral fractures, so the technique used for their reductions and correct healing make the procedure challenging. The success in using screws or pins in proximal fractures of the femur varies from 2% to 21% only, failure can occur due to poor positioning and the different settlements of the femoral heads. A 3D template was used as a guide, produced by computed tomography, to introduce three Steimann pins into the lateral face of a canine's greater trochanter, in order to reduce a fracture in the femoral neck. In veterinary medicine, the use of a computed tomography machine, and 3D printing through rapid prototyping, are tools that assist in surgical accuracy and planning, with the consequence of reducing anesthesia, surgery and risk of infections. For surgeons, it helps to reduce errors made due to lack of planning or information on the areas worked on. The academic relevance of using accurate diagnoses and treatments using auxiliary diagnostic methods, demonstrates the small universe to be explored in veterinary medicine. Therefore, the presented method has an innovative character, which brings a new utility for computed tomography devices in cases of osteosynthesis, and presents one of the uses of rapid prototyping technology.
