Abstract
The invention belongs to the medical equipment technical field, in particular to a low incisura inclined screw hole acetabulum back wall bone fracture plate. The fracture bone plate is composed of a plate body and a screw hole; steel plate body is like a 'hat', the middle part arc part is in certain radian and is consistent with the anatomy shape of acetabulum, alar parts at the two side slightly raise to adapt the anatomy shape of acetabulum at nodule extension position with upper ilium and lower ischium; the plate body thickness of the steel plate of the invention is not uniform, the thinner side is at the connection position with acetabulum back wall margin, the thicker side is at the contact position with acetabulum back column, the middle transits gradually, and the overall design is consistent with sclerotin thickness variation of acetabulum. The invention can be used in operation only by adjusting according to fracture situation and has good fit perfectly with local sclerotin, no bigger hole can be produced, and a bolt can be prevent from entering articular cavity when being imbedded.
Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to a kind of internal fixation blade plate that is used for the acetabular bone posterior wall fractures.
Background technology
Along with the Chinese society rapid development of economy, the contingency of building and communications frequently takes place, and wherein a lot of patients often merge fracture of acetabulum simultaneously.According to the typing of fracture of acetabulum, proportion is the highest in all fracture of acetabulums for acetabular bone posterior wall fractures (Acetabular posteriorwall fracture), accounts for about 1/4.Because the acetabular bone posterior wall fractures relates to the hip joint face, and often merge the femoral head backward dislocation, therefore, the majority treatment that need undergo surgery, require the articular surface anatomical reduction and give enough internal fixation, avoid hip joint instability and traumatic arthritis to form to obtain early functional exercise.
The internal fixation mode of acetabular bone posterior wall fractures is mainly screw or steel plate is fixed, use indication difference separately.Because the anatomical structure of acetabular bone is more special, its rear wall is special arch-shaped, and the glenoid cavity edge is comparatively poor, has only 2～3mm, and certain difficulty is arranged when adopting steel plate fixedly.Clinical way is after sclerite is resetted at present, temporary fixed, use earlier a matter soft template at the acetabular bone rear wall according to its natural shape bending, select the reconstruction plate of an appropriate length again or rebuild the shape bending of band according to template, the steel plate of unnecessary length need cut off, and carries out fixing operation subsequently again.In operation actual, because local field of view guarantor dew is limited, need adjust the flexibility of steel plate repeatedly, to adapt to the shape of acetabular bone rear wall as far as possible, keep the submissive of steel plate.
No matter present employed steel plate or rebuild band, its thickness all keeps homogeneous, is with just the same with steel plate or the reconstruction that use at other positions.And the thickness of acetabular bone rear wall and inhomogeneous, and there is an arch radian, so as a rule, steel plate after fixing and reconstruction band are also not exclusively docile and obedient with the sclerotin of fracture site, may have certain clearance, this just causes the skewness of stress easily, finally cause the internal fixation failure, steel plate or reconstruction band can rupture, and cause great misery to the patient, severe patient needs surgical procedure once more, and this has increased patient's financial burden again.
In sum, at the acetabular bone rear wall internal fixation steel plate that uses at present or rebuild band, because the defective in the design, use in the operation and inconvenient, not only do not conform to the shape of acetabular bone rear wall and, need to adjust bending temporarily in the art; And the thickness homogeneous of steel plate, fixing not submissive, cause the internal fixation failure easily, influence the recovery of whole surgery quality and postoperative patient.
Summary of the invention
The object of the present invention is to provide a kind of easy and simple to handle, safety good, can be used for the blade plate of acetabular bone posterior wall fractures internal fixation.
Acetabular bone rear wall internal fixation blade plate provided by the invention is improved on the general steel plate basis of present clinical use and is obtained, and is made by medical stainless steel or titanium alloy, repeatedly high-temperature sterilization.This anatomical plate is similar to general steel plate, is made of plate body 1 and screw hole 2; See that from the side plate body is like " carnival hat shape ", the mid portion portion 11 that arches upward is a radian, is consistent with the anatomical shape of acetabular bone, and alar part 12 slightly perks in two ends are to adapt to the anatomical shape of acetabular bone and upper end ilium and lower end ischial tuberosity continuity place.
The plate body thickness of steel plate of the present invention is also inhomogeneous, thin a side-line and acetabular bone rear wall side edge place, and a thick side-line and acetabular bone rear pillar contact position, the centre is transition gradually, and global design is consistent with the sclerotin varied in thickness of acetabular bone.
The design of screw hole 2 of the present invention can be locking or non-locking device, different with the general steel plate screw hole perpendicular to the design of plate body, this screw hole center and plate body angle at 45 to a thick side, can avoid screw to enter articular cavity by a thin skew back when inserting screw by this direction.
The present invention is according to the design of acetabular bone rear wall anatomic shape, and the portion 11 that arches upward is connected the transition nature with two ends alar part 12, only need in the operation slightly to adjust and can use according to fracture situation, and good with the submissive property of local sclerotin, can not form than macrovoid; And can avoid screw to enter articular cavity when inserting screw.

Fig. 2 is a side structure sketch map of the present invention.
Fig. 3 is a ramp structure sketch map of the present invention.
Fig. 4 is the oblique design diagram of screw hole of the present invention.
Number in the figure: 1 plate body, 2 screw holes, 11 portions that arch upward, 12 alar parts.
The specific embodiment
Following embodiment further specifies the present invention, is limited to content of the present invention but can not limit.
Be made up of plate body 1 and screw hole 2 the acetabular bone rear wall anatomical plate of the present invention shown in the accompanying drawing 1～4, wherein plate body is made up of the portion of arching upward 11 and alar part 12 two parts again.According to differences such as patient's sex, ages, steel plate length is 13-20cm, and the screw hole number is 7-15, uniform distribution, and each screw hole spacing is 0.8-1.0cm.The present invention in use at first with acetabular bone posterior wall fractures block reset, after choosing the appropriate length steel plate and adjusting (bending or reverse) slightly according to the topography structure, places the acetabular bone rear wall with steel plate, settles screw to fix.
The present invention is easy and simple to handle, safety good, is applicable to the operative treatment of various acetabular bone posterior wall fractures, and the anatomical form design has avoided bending repeatedly to adjust steel plate, has saved operating time; In the time of steel plate uneven thickness one design, the sclerotin varied in thickness that makes steel plate and acetabular bone rear wall mutually, strong fixedly fracture, more submissive with local sclerotin; The oblique design of screw hole helps screw and places fully in the sclerotin, has avoided screw to enter the danger in hip joint chamber.
