Abstract

The invention discloses a fixing device for fractures of acetabulum anterior and posterior columns. The fixing device for the fractures of the acetabulum anterior and posterior columns comprises an installation part and a movable part detachably installed on the installation part, and further comprises a movable connecting structure and an adjusting assembly, wherein the movable connecting structure is arranged on the movable part; the movable connecting structure is used for making the movable part detachably installed on the installation part; the adjusting assembly is arranged between the installation part and the movable part; and the adjusting assembly is used for adjusting the included angle between the movable part and the installation part; The movable part and the installation part are movably connected and are detachable through the movable connecting structure, and thus, the whole device can be conveniently fixed onto the acetabulum anterior and posterior columns; the included angle of the movable part relative to the installation part can be adjusted through the adjusting assembly; the installation part is fixed onto a position where the acetabulum anterior and posterior columns are convenient to install, and then the movable part is adjusted to fix a fracture part, and the movable part and the installation part are fixed by means of an elastic fixing structure.,.

Description

technical field [0001] The invention relates to a medical device, in particular to a fixation device for acetabular anterior and posterior column fractures. Background technique [0002] Acetabular comminuted fractures have always been a difficult problem in trauma orthopedic treatment. The complex blood vessels and nerve structures around the pelvis, the difficulty of exposure, and the small number of screw placement areas all bring difficulties to the anatomical reduction of periacetabular fractures. For complex acetabular fractures, due to severe violence, comminuted fractures of the anterior column or posterior column often occur together with comminuted fractures or severe displacement of the quadrilateral area of ​​the acetabulum. [0003] After the acetabular reduction of such fractures, due to the poor reduction of fractures, it is easy to cause late hip osteoarthritis, femoral head necrosis and so on. At present, the main methods used in the treatment of acetabula...
