Pelvis displacement measuring method based on pelvis plain film

Abstract

The invention discloses a pelvis displacement measuring method based on a pelvis plain film. The method comprises the following steps of Step 1, X ray examination; Step 2, measuring basis building; Step 3, measurement and calculation; and Step 4, measurement result expression, wherein on a front and back position plain film, the anterior superior iliac spine (A) and the ischial tuberosity (B) areselected to be used as mark points; on an inlet position flat sheet , the sacroiliac joint front side (H), the anterior superior spine (G) and the sacrum endplate center (S) are selected to be used as mark points; on an outlet position plain film , the crista iliaca highest point (C), the anterior superior iliac spine (E) and the tuber ischiadicum (D) are selected to be used as mark points. According to the method, the pelvis front and back position, inlet position and outlet position X ray films are sufficiently utilized; whether the pelvis displacement occurs or not and the concrete displacement conditions are systematically measured; the reset path of the pelvis closed reduction is planned in an auxiliary way; the reset precision can be effectively improved; the operation time of theclosed reduction and the perspective time are reduced; and the bleeding quantity and the infection risk of a patient can be further reduced.

Description

technical field [0001] The invention relates to the technical field of pelvic diagnosis and measurement, in particular to a method for measuring pelvic displacement based on plain pelvic radiographs. Background technique [0002] The pelvis is an important structure that supports the spine and lower limbs. Its structural integrity is crucial to the transmission of human physiological mechanics. The pelvic ring contains many important organs, blood vessels and nerves. Severe complications such as functional disability. However, the treatment of pelvic fractures poses a very high challenge to orthopedic surgeons. Despite the rapid development of contemporary orthopedics, pelvic fractures still have high mortality and disability rates. In order to minimize the complication rate and postoperative survival rate of pelvic fractures, accurate reduction and timely fixation are particularly important. The traditional treatment method, open reduction and internal fixation, can be us...

Problems solved by technology

Through the previous literature review, different authors proposed or improved on the basis of the predecessors, and established a variety of measurement methods for pelvic displacement, but none of them can be widely accepted, and most of them lack standardization process, reliability and Poor stability and other issues, it is difficult to be well applied in clinical practice
