Abstract
The invention relates to a bone plate, in particular to an acromion dissection locking bone plate. The acromion dissection locking bone plate comprises a scapular spine region body, an acromion basilar part body and an acromion region body, wherein the scapular spine region body is provided with 1-4 locking pressured screw holes and 1-4 locking screw holes, the acromion basilar part body is provided with 1-2 locking pressured screw holes and 1-2 locking screw holes, and the acromion region body is provided with 1-2 locking pressured screw holes and 3-5 locking screws. The acromion dissection locking bone plate has a curved design matched with surfaces of the acromion and the scapular spine and can be fit onto the acromion bone skillfully, holding force and strength of screws for fixing fracture bones are increased by the design of combining the locking screw holes on the bone plate with common screw holes, side shear and torsion stress resistance in fixing of the bone plate is increased by the design including side wings and the locking screws thereon, and thus, the bone plate is more reliable in fixing.
Description
Technical field
The present invention relates to a kind of blade plate, relate in particular to a kind of acromion and dissect locking-typed blade plate.
Background technology
Acromion forms acromioclavicular joint together with clavicle far-end, acromion, processus coracoideus and coracoacromial ligament form coraco-acromial arch jointly, having of coraco-acromial arch is beneficial to the gap slip under acromion of shoulder sleeve muscle, and acromion basilar part has participated in the composition of spinoglenoid notch, for this reason, acromion fracture, as a kind of intra-articular fracture of specific type, if dealt with improperly, must have influence on the functional activity of shoulder joint.Because acromion protrudes from shoulder, mostly be top-down direct violence and hit, or by the powerful leverage of humerus, cause acromion fracture, mostly be cross-section property or short oblique property fracture, acromion fracture piece is subject to the tractive of the effect of upper limb weight and triangular muscle, lower displacement, affects the abduction function of shoulder joint forward.In addition acromion fracture piece moves down, can cause acromion downslide membrane vesicle, i.e. the second shoulder joint gap turn narrow, and subacromial bursa pathological changes can make head of humerus produce friction when motion, the all muscle of shoulder is likely damage all, but modal is shoulder sleeve and the damage of biceps brachii m. flesh key, thereby affects shoulder joint function.
For avoiding the generation of these complication, the acromion fracture of displacement is answered to horizontal reset internal fixation, also should detect and whether merge rotator cuff injury, and be repaired.For without displacement or the unconspicuous acromion fracture that is shifted, traditional method adopts triangular bandage suspension or local compression suffering limb abduction fixing etc. more, but can not change the situation that acromion downslide membrane vesicle narrows down, thereby affects function of joint.Ogawa II type acromion fracture refers to the acromion (comprising acromion cervical region and acromion portion on ordinary meaning) between acromioclavicular joint face trailing edge and acromial angle.If fracture is displacement downwards, changed the inclination angle of acromion, can cause narrow gaps under insecondary acromion, thereby produce acromion impingement sign and rotator cuff injury, have operative treatment indication, operation adopts Kirschner wire or tension band wire internal fixation, though can obtain certain curative effect, it also exists pinprick to infect, draw point loose or dislocation, backshank stays in subcutaneous or skin and causes pain outward, the shortcoming such as be unfavorable for suffering from shoulder functional exercise and lie up.Operation adopts in the oblique T-shaped palmar locking steel plate of distal radius fixing, though there is in recent years report, from acromion anatomic form matching and interior constant intensity, still has certain deficiency.Ogawa III type acromion fracture refers to acromion basilar part fracture, if fracture of spina scapula malunion can cause the cripetura of rotation sleeve acting force arm, the symptom of the false shoulder sleeve paralysis such as generation shoulder abduction is unable, operation utilizes common reconstruction plate to fix, its hold is inadequate, though there is certain hold and rebuild locking compress steel plate, but the side shearing force that is difficult to antagonism fracture, simultaneously far-end hold-down screw number less and make screw easily loosening, hold weaken, cause clinical practice difficulty, affect therapeutic effect.If adopt in the oblique T-shaped palmar locking steel plate of distal radius, fix, from acromion anatomic form matching and interior constant intensity, equally still have certain deficiency.
Summary of the invention
The object of the invention is: the deficiency existing for prior art, a kind of anatomical features that meets acromion portion is provided, effectively fixing acromion is dissected locking-typed blade plate.
For realizing the present invention's object, be achieved by the following technical solutions:
