Aspectos anatômicos da região femoral lateral aplicados a injeção intramuscular em sagui-de-tufo-branco (Callithrix jacchus Linnaeus, 1758).

Abstract

The Common marmoset (Callithrix jacchus) has been widely used in studies of infectious diseases and neuroscience programs. Due to the small body, perform clinical management in these animals is not an easy task, to be successful, it requires experience and expert knowledge of anatomy, physiology, natural behavior and feeding management. The objective of this study is the identification of a security point for application of intramuscular injection into the hindlimb of common marmoset, with the identification of the muscles based on sciatic nerve path, the mais injury nerve of this procedure. Therefore, we used 10 cadaver of common marmoset, in which the gluteal and femoral regions were dissected for the identification and description of muscles, sciatic nerve path and bony projections of these regions. Lines were drawn of bone projections and dye injections were carried out at different points of the muscles. Were identified these muscles: superficial gluteus, medium gluteus, deep gluteus, piriformis, gluteofemoral, quadratus femoris, gemellus, tensor fascia lata, biceps femoris, abductor crural caudal, quadriceps femoris (vastus lateral, rectus femoris, vastus and vastus intermedium), sartorius, gracilis, adductor longus, adductor magnus, short adductor, pectineus, semimembranosus and semitendinosus. The iliac crest, the greater trochanter, the ischiatic tuberosity and the lateral condyle of the tibia were palpable bony projections. The point of the triangle area A (IV) showed greater security because there is no danger of injury to the sciatic nerve or of venous or arterial aspiration, besides having a good area for application of intramuscular injection through the muscle clamping technique.
