Plate.
Background technology
The concept of acetabular bone squared region is proposed by external Judet when proposing Acetabular Both-column concept within 1964 earliest.Squared region
Sclerotin it is relatively thin be easy to fracture, squared region fracture femoral head would generally be caused to shift inwardly, severe patient causes centrality to take off
Position, is common in acetabular bone complexity fracture, such as the later half transverse fracture of Both-column Fractures, front pillar, "T"-shaped fracture etc..Since squared region is special
The reason for different sclerotin form and the specific position close to hip joint, treatment acetabular bone squared region fracture is always in orthopaedic trauma
The challenge for the treatment of.Fracture for different types of squared region, its treatment method is also different.
Chinese patent literature CN105496538A（Application number 201610080395.X）A kind of acetabular bone squared region is disclosed to connect
Hone lamella, its bone plate are stereochemical structure, and the curved shape of the various pieces of bone plate respectively with acetabular bone squared region is adapted, synthetism
Plate each several part can carry out fracture of acetabulum effectively fixed.The invention can be carried out at the same time spinous process of the seventh cervical vertebra folding before and after acetabular bone effectively solid
It is fixed, can by the fixation for acetabular bone squared region arcuate line and ischial spine part, add covering to acetabular bone squared region and
Support, but it is when in use, due to the special locations of structures in squared region, installs and inconvenient, it is impossible to accurately positioned.
Chinese patent literature CN203244449U（Application number 201320106378.0）Disclose one kind and be used for bone groin
The fixator of approach marrow mortar squared region fractures, it includes fixed admire plate and fixing screws, the fixation admire plate plate body outside
Profile is arc-shaped, and the middle part plate body pre-bending radian of fixed plate of admiring is more than arcuate line and is in interior low outer high inclined plane shape, fixed plate of admiring
Middle part plate body slope is less than boundary line bone face slope, and the both ends plate body of fixed plate of admiring is in gradually increased low inside and high outside oblique from inside to outside
Planar, fixed to be evenly arranged with multiple mounting holes on plate by the emperor himself, fixed mounting hole on the both ends plate body of plate by the emperor himself is ellipse, is fixed
The mounting hole on the middle part plate body of plate is undercut mark ellipse by the emperor himself, and the fixing screws consolidate fixed plate of admiring through the mounting hole
Due on sclerotin.The utility model provide fixator can be to a certain extent solve bone groin approach marrow mortar squared region
The problem of fractures, but it is not easy to operate when mounted, it is difficult to position, while the closure effect of fracture line need to be carried
It is high.
Utility model content
The purpose of this utility model is that solve the above problems, there is provided a kind of titanium for acetabular bone squared region fractures
