METHOD FOR DETERMINING LENGTH OF FIXATIVE FOR EXTRA-ARTICULAR OSTEOSYNTHESIS OF FEMORAL NECK

摘要

The invention relates to traumatology and orthopedics, and can be used to determine the individual fastener lengths at the extra-articular femoral neck osteosynthesis. The purpose of the invention - improved quality of surgery by increasing the accuracy of selection of retainer length during operation. The inventive method for determining an individual fastener length for extra-articular femoral neck ostoosin- thesis comprises applying labels on a spoke of the guide at a predetermined distance from its sharp end, the introduction of needles into the bone, and the measurement of X-ray images on FASD radiograph. When this needle is introduced into the bone before the mark in the roentgenogram measured length of the image portion of intraosseous needles and its continuation As the distance from the image to the sharp end of the spokes of articular cartilage head further determined by forb A mule X: - + A + B-C, wherein X - Favored as "retainer length, and - the length of the spokes from the sharp end to the mark, and - an image length inside the bony part of the spokes on the radiograph, B - part retainer namechaema to left over the surface of the femur part, ab - distance on radiographs of the end of the spokes to the cartilage of the femoral head, mp C aniruemoe distance allowed emoe from the sharp end of the retainer to the cartilage of the femoral head. 2 yl.
