Technical Field

The invention relates to an integrated external fixation bracket for front and rear pelvis rings, belonging to the field of orthopedic appliances.

Background

Unstable pelvic fracture often accompanies complications such as vascular nerve injury, systemic blood coagulation disorder, lower limb deep vein thrombosis, hemorrhagic shock and the like, and endangers the life of patients. The antishock treatment is carried out in the shortest possible time, and meanwhile, the fixing is effectively reset, the bleeding is controlled, and the death rate and the occurrence of complications can be reduced. The pelvis external fixation support has the advantages of small wound, good fixation effect, capability of protecting the blood transportation of periosteum and soft tissues to the maximum extent, shortening absolute bed-lying time and performing functional exercise at an early stage, convenient operation, low anesthesia requirement and capability of immediately performing operation in a rescue room. Clinically, the external pelvic fixation support cannot fix the fracture of the anterior and posterior pelvic rings at the same time, and does not have adjustable pressurization. The commonly used external fixing support technology is also the external fixing support of the anterior pelvic ring, and the external fixing support with definite curative effect is not available for the posterior pelvic fracture which has larger influence on the life of a patient. The posterior ring fracture easily causes serious vascular and neurological complications, causes high disability rate and lethality rate, and the research on the timely fixing bracket of the posterior structure has very important significance.

At present, no external fixing bracket capable of fixing the front ring and the rear ring of the pelvis simultaneously exists at home and abroad, and effective pressurization and fixation can be carried out in the horizontal direction and the vertical direction, namely, strong effective early fixation is obtained in a minimally invasive mode, and the occurrence of secondary injury and complications is reduced. The existing method for placing the screw on the external fixing support for the anterior pelvis ring mainly comprises an anterior upper part (ilium wing) and a anterior lower part (acetabulum upper part), wherein the ilium wing screw placing method is most commonly used. Pelvic posterior ring fractures, particularly pelvic fractures from high energy trauma, have a very high mortality rate. The method has important clinical significance on how to achieve early, minimally invasive, quick and effective strong external fixation for multiple pelvic fractures, especially for the injured people with combined anterior and posterior ring fractures.
