SU1629034A1 - Method for diagnosis of injuries to the pelvic articulations - Google Patents

Description

The invention relates to medicine, namely radiology in traumatology and orthopedics.

The purpose of the invention is to improve the accuracy of diagnosis.

The method is carried out as follows.

The patient is placed for pelvic radiography on the radiographic table, is placed lying on his stomach with equal-sized supports lying under the anterior surface of the pelvis and pubic symphysis.

For the manufacture of supports, we recommend a highly direct-permeable plastic. The diameter of their support surface up to 80 mm. We recommend using two sets of supports: one with a height of 50 mm and the second with a height of 100 mm. This height of the supports is due to the need to exclude the possibility of replacing the pelvis support with an enlarged abdomen of the patient or the massive muscles of his hips instead of the recommended points of support. The size of the support of more than 100 mm has never been used by us. However, if necessary, you can put one set of supports on the other and get the height of the support 150 mm.

On the radiographs obtained, the image of the pelvis bones of the patient slightly increases, depending on the height of the support. To eliminate the distortions thus inflicted on the image and the possibility of rigorous mathematical study of the information obtained, we recommend using supports with a height of 50 mm and only if necessary with a height of 100 and 150 mm.

The patient's pelvis, located in the laying by the proposed method, rests on the radiographic table with three rigid points of support: the anteroposterior pelvis and pubic symphysis. The position of any body can be stable if it has at least three points og.ry. The patient’s pelvic pivot points are hard, which practically excludes the influence of their trophism on the spatial position of the pelvis. In this position, the supporting surface of the pelvis is parallel to the plane of the table, which completely eliminates the possibility of laying asymmetry of the display of the patient's pelvis on radiographs.

This patient is placed belly down on the deck of the radiographic table. Under the anterior superior spine and the pubic symphysis of the pelvis of the patient, identical supports are placed in size. They must be of a height sufficient for the patient to rest through them on the surface of the radiographic table and to completely exclude the possibility of supporting the patient's stomach on the radiographic table. For laying a patient with an increased nutritional body, it is necessary to use higher supports. As supports you can use a set of identical cubes of plastic or wood. The hands of the patient are located along the body. With this arrangement, the pelvic points are at the same distance from the surface of the X-ray table. The supporting plane of the patient's pelvis is parallel to the surface of the x-ray table, which guarantees that the true relationship of the pelvic bones is obtained on radiographs.

Thus, the proposed method allows to obtain an image without projection distortion of the relationship of the pelvic bones, which in 100% of cases provides an adequate interpretation in the diagnosis of their disorders.
