Abstract
The utility model relates to an inner fixing steel plate for the fracture of sacroiliac joints. The utility model can be divided into an inner unilateral fixing steel plate for sacroiliac joints and an inner bilateral fixing steel plate for sacroiliac joints, wherein, the inner unilateral fixing steel plate for sacroiliac joints is in the shape of a flat horseshoe, and five screw holes are drilled on the inner unilateral fixing steel plate for sacroiliac joints. The inner bilateral fixing steel plate for sacroiliac joints is in the shape of two arched bridges, both ends of the inner bilateral fixing steel plate for sacroiliac joints are connected with horseshoe-shaped side wings, and five screw holes are drilled on the two side wings respectively. The utility model adopts integral multipoint fixation, and the utility model has the advantages of good function, strong stability and conspicuous inner fixation function. The utility model can improve the healing rate of fracture obviously and shortens the healing time of fracture.
Description
This utility model relates to a kind of sacroiliac joint fracture internal fixation steel plate.
For serious unstable fracture of pelvis, improper as early time treatment, often can cause not isometric because of concurrent pair of lower limb of the instability of pelvis in late period, sacroiliac joint pain and following waist degeneration.Thereby new viewpoint has been arranged on the Therapeutic Principle of unstable fracture of pelvis in recent years, and advocate early stage open reduction internal fixation, but pelvis is complex-shaped, the fracture of different parts need be with dissimilar internal fixation devices.At present, both at home and abroad to one of kind of fracture of pelvis: the conventional therapy of sacro-iliac joints fracture dislocation, mainly adopt two kinds of methods to carry out internal fixation.First method is to adopt many pieces of simple screws to carry out multiple spot to fix.But because sacroiliac fracture-dislocation is a comminuted fracture often, when especially bilateral is fracture dislocation.Adopt this kind fixing means to lack the overall fixed function.Thereby patient is ambulation in early days, easily causes the many complication due to the long-term bed.Second method is to adopt double stick to carry out the sacroiliac joint internal fixation.Though more piece of multiple screws of this method is reasonable, the operation more complicated, it is bigger to wear excellent difficulty, is difficult to sometimes prove effective, and particularly to pulverizing more serious sacroiliac fracture-dislocation, then can't carry out internal fixation, yields internal fixation operation in the art sometimes.In addition, to one-sided sacroiliac fracture-dislocation, operation still need appear the both sides sacroiliac joint, and operative incision is big, and damage is flat heavy, has increased unnecessary misery to patient.
The purpose of this utility model be adopt in order to provide a kind of that whole multiple spot is fixed, better function, stability are strong, the internal fixation effect significantly, can obviously improve the union of fracture rate, shorten the sacroiliac joint fracture internal fixation steel plate of healing time.
The purpose of this utility model can realize by following measure:
A kind of sacroiliac joint fracture internal fixation steel plate can be divided into one-sided sacrum ilium internal fixation steel plate and bilateral sacrum ilium internal fixation steel plate; Wherein one-sided sacrum ilium internal fixation steel plate is the plane shape of a hoof, is drilled with 5 screw holes thereon; Bilateral sacrum ilium internal fixation steel plate is two arch-shaped, connects with being horseshoe-shaped flank at its two ends, respectively is drilled with 5 screw holes on two flanks respectively; Screw hole on the steel plate is arranged the shared summit of two triangle for two isosceles triangles that equate; Base two screw holes of two isosceles triangles are located at horseshoe-shaped two ends.
This utility model has following advantage compared to existing technology:
1, this utility model adopts and to be the horseshoe-shaped steel plate in plane and one-sided sacroiliac joint fracture is carried out internal fixation and employing to be the two arch-shaped steel plates of double-vane bilateral sacroiliac joint fracture is carried out internal fixation, be to use the multiple spot fixation principle, no matter thereby it is to joint dislocation or serious comminuted fracture, all has stronger internal fixation effect.
2, adopt the biphase equilateral triangle screw hole on a shared summit to fix on the steel plate of the present utility model; Through biological mechanics determining, the effect that its stability is compared simple many pieces of multiple screws increases 10-20 doubly, increases 8-15 doubly than the effect of double stick internal fixation.
3, this utility model improves the union of fracture rate greatly and reaches 98.2%, and has shortened healing time, thereby has shortened patient's bed rest time.
4, of the present utility model simple to operate, to one-sided sacroiliac fracture-dislocation, operation need not appear the both sides sacroiliac joint, the patient is lost little, has alleviated patient's misery.
Concrete structure of the present utility model is provided by the following drawings:
Fig. 1 is the perspective view of one-sided sacroiliac joint internal fixation steel plate of the present utility model
The one-sided sacrum ilium of 1-internal fixation steel plate 2-screw hole
Fig. 2 is the perspective view of bilateral sacroiliac joint internal fixation steel plate of the present utility model
3-bilateral sacrum ilium internal fixation steel plate
Fig. 3 is the vertical view of bilateral sacroiliac joint internal fixation steel plate
This utility model is also incited somebody to action in conjunction with the accompanying drawings, and 1,2,3 embodiment are described in further detail:
With reference to Fig. 1, a kind of sacroiliac joint fracture internal fixation steel plate can be divided into one-sided sacrum ilium internal fixation steel plate (1) and bilateral sacrum ilium internal fixation steel plate (3); Wherein one-sided sacrum ilium internal fixation steel plate (1) is the plane shape of a hoof, is drilled with 5 screw holes (2) thereon; Bilateral sacrum ilium internal fixation steel plate (3) is two arch-shaped, connects with being horseshoe-shaped flank at its two ends, respectively is drilled with 5 screw holes (2) on two flanks respectively; Screw hole on the steel plate (2) is arranged the shared summit of two triangle for two isosceles triangles that equate; Base two screw holes (2) of two isosceles triangles are located at horseshoe-shaped two ends
With reference to Fig. 3, the arch bridge span of bilateral sacrum ilium internal fixation steel plate (3) and the camber of flank and arch bridge are determined by the human body model.
Claims (2)
1, a kind of sacroiliac joint fracture internal fixation steel plate is characterized in that internal fixation steel plate can be divided into one-sided sacrum ilium internal fixation steel plate (1) and bilateral sacrum ilium internal fixation steel plate (3); Wherein one-sided sacrum ilium internal fixation steel plate (1) is the plane shape of a hoof, is drilled with 5 screw holes (2) thereon; Bilateral sacrum ilium internal fixation steel plate (3) is two arch-shaped, connects with being horseshoe-shaped flank at its two ends, respectively is drilled with 5 screw holes (2) on two flanks respectively.
2, sacroiliac joint fracture internal fixation steel plate as claimed in claim 1 is characterized in that the screw hole (2) on the steel plate is arranged the shared summit of two triangle for two isosceles triangles that equate; Base two screw holes (2) of two isosceles triangles are located at horseshoe-shaped two ends.
