Abstract
The utility model discloses a fixation steel plate for acetabular posterior edge fracture, which comprises a steel plate and steel nail holes. The internal side of a middle arch-shaped area is in the shape of teeth and the nail holes are drilled in the gum. The length of steel plate is 13-18cm, the width is 1.2-1.5cm, and the distance between the nail holes is 0.8-1.0cm. The nail holes are in the shapes of vertical hole, obtuse angle hole and acute angle hole. The utility model has the following characteristics: an interior fixation device is an acetabular posterior edge anatomy plate, with two different materials: stainless steel and titanium alloy. When a fracture block is reset, the anatomical plate is attached on the fracture block, thereby not only drilling screws into the screw holes on both ends of the steel plate, but also drilling the screws into the screw holes on the fracture block, without drilling the screws into the acetabulum, thus playing the role of rigid internal fixation and leading the hip joint to do early exercises.
Description
Technical field:
This utility model relates to a kind of internal fixation steel plate, is applicable to acetabular bone trailing edge fracture.
Background technology:
Mentioning acetabular bone trailing edge application reconstruction plate the 2835th page of " Campbell's bone surgery " (the tenth edition) the 6th volume fixes, earlier sclerite is resetted, again reconstruction plate is attached on the sclerite, thereby the screw hole in the steel plate two ends pierces the effect (not piercing screw under half situation of the screw hole on the sclerite, in case screw pierces the activity that influences hip joint in the acetabular bone) that screw plays the bone fixation folded block.The shortcoming that this fixing means exists is: the screw hole on the sclerite is not if pierce screw, and fixing of sclerite is firm inadequately, and hip joint can not carry out early ambulant and take exercise; Screw hole on the sclerite is if pierce screw, and screw pierces easily influences the hip joint activity in the acetabular bone.
Summary of the invention:
Task of the present utility model is: propose a kind of internal fixation steel plate that is suitable for acetabular bone trailing edge fracture, can pierce screw by the screw hole on sclerite, strong internal fixation makes hip joint carry out early ambulant and takes exercise, be unlikely to make screw to pierce in the acetabular bone again, influence the hip joint activity.Task of the present utility model is done in such a way that acetabular bone trailing edge fracture fixed steel plate, and it comprises steel plate, and the steel nail hole is characterized in that: the side in middle arch area is the tooth shape, is equipped with the nail hole at the gingiva place.The length 13-18cm of steel plate, wide 1.2-1.5cm, nail between the hole apart from 0.8-1.0cm, the shape in steel nail hole has upright opening, hole, obtuse angle and acute angle hole.The utlity model has following characteristics: inner fixer is dissected plate for the acetabular bone trailing edge, material is two kinds of rustless steel and titanium alloys, after sclerite resetted, the dissection plate is attached on the sclerite, can pierce screw at the screw hole at steel plate two ends, can pierce screw by the screw hole on sclerite again, also be unlikely to make screw to pierce in the acetabular bone, thereby play the effect of strong internal fixation, make hip joint carry out early ambulant and take exercise.
Description of drawings:
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the vertical view of Fig. 1.
Drawing explanation: 1, steel plate, 2, the nail hole, 3, arch area, 4, groove.
The specific embodiment:
Describing in detail in conjunction with above accompanying drawing is embodiment, and the shape at steel plate 1 two ends is plane, and the centre is an arch, in the middle of the place, plane of steel plate one end and the arch junction groove 4 is arranged, a side of arch area 3 is tooth shapes, is equipped with nail hole 2 at the gingiva place, to increase thickness, thickness difference in arch area, bending leeway is arranged, the length 13-18cm of steel plate, wide about 1.2-1.5cm, nail between the hole apart from 0.8-1.0cm, the shape in steel nail hole has upright opening, hole, obtuse angle, acute angle hole.Be applicable to that acetabular bone trailing edge fracture, acetabular bone rear pillar fracture, acetabular bone trailing edge merge rear pillar fracture, acetabular bone trailing edge transverse fracture, the steel plate of the different screw holes of classification of fracture different choice is fixed.
Claims (2)
1, acetabular bone trailing edge fracture fixed steel plate, it comprises steel plate, the steel nail hole is characterized in that: the side in middle arch area is the tooth shape, is equipped with the nail hole at the gingiva place.
2, acetabular bone trailing edge fracture fixed steel plate according to claim 1 is characterized in that: the length 13-18cm of steel plate, wide 1.2-1.5cm, nail between the hole apart from 0.8-1.0cm, the shape in steel nail hole has upright opening, hole, obtuse angle and acute angle hole.
