Description
Technical field
Type of the present invention belongs to a kind of medical instruments field, be specifically related to one be exclusively used in region acromialis, spine of scapula,
The fracture such as clavicle far-end is accompanied or is not accompanied the interior combined fixator needed for acromioclavicular joint dislocation.
Background technology
Along with economic development, the industry such as traffic, building is flourishing, and fracture of scapula is the most common in recent years, accounts for
The 3%～5% of shoulder fractures, close to the 1% of whole body fracture, fracture of coracoid process of scapula accounts for the 3%～13% of fracture of scapula.
It is that fracture of scapula is treated it is crucial that recovery anatomic form and mechanics are stable as far as possible.Early functional exercise.In the past
To severe comminuted fracture of scapula, because of the most definite effective fixing means, frequently with non-operative treatment,
Easily cause that malunion of fracture, shoulder joint be unstable and the sequela such as the situation of upper extremity function generation obstacle.With
Patient to require day by day to improve to quality of life, functional rehabilitation good after fracture becomes the emphasis that patient pays close attention to.
Previously it has been generally acknowledged that and mostly can obtain good efficacy through expectant treatment.But a lot of scholar's retrospective studies find
Expectant treatment can remain many sequela.Increasing scholar has recognized the importance of surgical operation therapy.With
Patient to require day by day to improve to quality of life, functional rehabilitation good after fracture becomes the emphasis that patient pays close attention to.
Want to obtain good functional rehabilitation, in addition to for surgical indication, increasingly tend to use operative treatment,
Purpose is all resume stability.
Scapula is one piece of irregular triangle flat bone, before slightly concave, point two face three edge.Neck of scapula is narrow,
Sclerotin is weak, easily fractures, and its stability relies on the integrity of three posts, if fracture is failed to pinpoint a disease in diagnosis, easily causes fracture
Malunion, may result in glenohumeral instability and determines or dislocation.Scapula is a part for shoulder suspention complex,
Connect upper limb and axial bone, have abundant muscle to hold about, be also starting point and the attachment point of polylith muscle.
Accurate Diagnosis fracture of scapula, has important value to selecting therapeutic scheme and assessment state of an illness prognosis.Due to omoplate
Bone taxonomic hierarchies is complex, there is no unified criteria for classification at present.Common sorting technique has Hardegger
EASD (AO)/bone wound orthopaedics association of the U.S. (OTA) typing is fixed in typing, Mille typing and the world.
Hardegger typing: can specifically be subdivided into fracture of scapular body, Scapula glenoid edge fracture, Scapula glenoid nest fracture,
Anatomical neck fracture, fracture of surgical neck, acromion fracture, fracture of spina scapula and fracture of coracoid process of scapula.Most scholars
Think and fracture of scapula especially some serious displacement type fracture of scapula, fracture of scapula are involved in shoulder joint
Side's suspention complex injury, as being more than acromion and fracture of coracoid process of scapula, the omoplate of 5mm with clavicular fracture, displacement
Bone fracture merges brachia plexus injury or is both needed to go amass by the fracture merging suprascapular nerve injury of scapular notch
Pole operative treatment, can to a certain degree exempt the shoulder dysfunction that expectant treatment is caused, be more beneficial for
Its functional rehabilitation.For there being the fracture of scapula of displaced, the most conventional employing expectant treatment, usually make
Become traumatic arthritis, pain, the serious sequela such as limitation of activity.The quality of the reduction of the fracture is to prognosis very
Important, the strong fixing basis being postoperative function and taking exercise, is also to ensure that the important step of surgical effect.
Use open reduction and Kirschner wire fixation, owing to topography is complicated, wound is big, surgical technic requires height, postoperative extensive
Also it is difficult to reach ideal effect again.Fracture of scapula more after, on the one hand depend on the degree of injury of fracture,
On the other hand well reset with operation and be fixed with substantial connection.Just when come to see, internal fixation treatment optional
Select material category the most, reconstruction plate, T steel plate, deformed steel flats, calcaneal steel plate and Kirschner wire, steel
Silk, absorbable and nonabsorable screw.The geometric shape of scapula is very irregular, and anatomical position is relatively deep,
Attachment muscle is many, therefore, has the probability of raw nonunion more occurred frequently；Moreover internal fixation material need to try one's best
Unnecessary misery is born to exempt patient's Repeated Operation from the point of view of permanent inserting.Comprehensive two sides
Face factor considers, titanium alloy material is not only has higher inert metal, and plasticity is very strong, has
Good biocompatibility, the most both can reduce, after inserting, tissue produced too much pessimal stimulation, again can be abundant
Moulding to guarantee to produce with processus coracoideus district preferably to stick effect, and can be for being effective against shoulder mobility
Time produce and separate stress and shear stress the most fixing intensity is provided.
Open source literature also reports the internal fixation device of some scapulas at present, and through retrieval, we take passages such as
