Abstract:

Objective    To determine the anatomical basis of an algorithm for needle insertion in femoral nerve block. Methods Five unfixed corpses underwent whole body carboxymethylcellulose/lead oxide injection for CT scanning and three-dimensional reconstruction. Five bodies were injected with red latex. Femoral triangle were dissected by layers to document the precise course,location and relationships of the femoral nerve,femoral artery,and other anatomical structures with relevance to the femoral nerve block.  Results    Structures relevant to the femoral nerve block were located between the inguinal ligament and a line parallel to it at the level of the greater trochanter. The distance between the two lines was (5.8±1.6) cm. Profunda femoris artery was could be frequently encountered at the level of the parallel line, which crossed the femoral nerve in 85 percentages point. Conclusions The safe zone of femoral nerve block is located between the inguinal ligament and a line parallel to it. ?Using volume rendering technique is very useful for study of the location and relationships of artery with other structures.
