Nuevo sistema para la ayuda en el enclavamiento distal de varillas intramedulares usadas en fracturas de huesos largos

Abstract

Each year are performed more than 492, 000 surgeries on the world for repair fractures in long bones. The most used method to fix this problem is the closed intramedullary nailing, According as surgeons the most difficult task is the interlocking of the nail. The present work proposes a new system for detection of the intramedullary nail's holes used in rehabilitation of fractures in long bones (tibia and femur). The proposed method is based on the use of permanent magnets and magnetic sensors to locate the exact point where the bone must be drilled for the interlocking of the nail. The proposed system is aiming to diminish the great radiation doses to surgeons and patients. The suggested device is portable and supplied by batteries to provide a total autonomy, easy to use and great reliability. © Springer-Verlag Berlin Heidelberg 2007.
