Description
Technical field
Type of the present invention belongs to medical instruments field, be specifically related to a kind of with memorial alloy for material make for
Internal fixation device during the position fracture such as bone spine of scapula portion, scapula acromion portion and processus coracoideus portion.
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.
The anatomy relationship that processus coracoideus is complicated makes it particularly important in the effect of shoulder.Previously expectant treatment has certain probability to draw
Send out and again occur that shoulder joint is unstable after union of fracture and the sequela such as the situation of upper extremity function generation obstacle.Along with
Quality of life is required day by day to improve by patient, and functional rehabilitation good after fracture becomes the emphasis that patient pays close attention to.
Fracture of coracoid process of scapula is fixed, there is relatively multi-method and arguement the most clinically.Want to obtain good function
Recovering, in addition to for surgical indication, increasingly tend to use operative treatment, purpose is all to recover processus coracoideus
Stability.And be the key performed the operation to processus coracoideus anatomical structure research.It is not only one of shoulder
Dissect identification point, shoulder diseases plays very important effect.It rises certainly near scapula exterior angle,
Around there is an anatomical structure of complexity: be positioned at outside clavicle coracoclavicular ligament below 1/4 handing-over coupled, beak
Prominent have coracobrachialis, coracoradialis and pectoralis minor attachment, and coracoacromial ligament medial extremity and coracohumeral ligament are attached to
The lateral border of processus coracoideus.It is to constitute shoulder joints stability and the important feature of function.Processus coracoideus is referred to as shoulder front portion
" beacon ", there are following 3 basic functions: the most numerous muscle (or tendon) and ligament depend on a little, 2.
Maintain the stability of shoulder joint front upper part, 3. constitute the part that shoulder upper suspention complex is indispensable.But mesh
Before less to the basic research of processus coracoideus, report from document, Feng irrigates monarch etc. respectively to 27 adult's processus coracoideuses
Carrying out anatomical Observation, Yang Huifeng etc. uses slide gauge and steel ruler to 20 example adult normal's shoulder joint specimen beak upper arms
Ligament carries out anatomic measurement, and because of needs obduction, number of cases is few.It is only to processus coracoideus or the measurement of coracohumeral ligament
With assessment clinical meaning, processus coracoideus district is lacked systematic study.Previously it has been generally acknowledged that and mostly control through conservative
Treatment can obtain good efficacy.But a lot of scholar's retrospective studies find that expectant treatment can remain many sequela.
Increasing scholar has recognized the importance of surgical operation therapy.Along with quality of life is required day by day to carry by patient
Height, 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 tending 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 to fracture of scapula especially some serious displacement type positive operative treatment of fracture of scapula row, can be one
Determine degree and exempt the shoulder dysfunction that expectant treatment is caused, be more beneficial for its functional rehabilitation.For having
The fracture of scapula of displaced, the most conventional employing expectant treatment, often result in traumatic arthritis, pain
Bitterly, the serious sequela such as limitation of activity；Use open reduction and Kirschner wire fixation, owing to topography is complicated, wound
Greatly, surgical technic require height, post-operative recovery is also difficult to reach ideal effect.Fracture of scapula more after, one
Aspect depends on the degree of injury of fracture, on the other hand well resets with operation and is fixed with substantial connection.Just
When coming to see, the optional material category of internal fixation treatment is the most, reconstruction plate, T steel plate, profile iron
Plate, calcaneal steel plate and Kirschner wire, steel wire, absorbable and nonabsorable screw.The geometric shape of scapula
Very irregular, and anatomical position compared with deep, attachment muscle is many, therefore, has raw nonunion more occurred frequently
Probability；Moreover internal fixation material need to try one's best from the point of view of permanent inserting to exempt patient's Repeated Operation
And bear unnecessary misery.Comprehensive two aspect factors consider, titanium alloy material is not only has higher inertia
Metal, and plasticity is very strong, has good biocompatibility, the most both can reduce after inserting group
Knit the too much pessimal stimulation of generation, again can be the most moulding to guarantee to produce with processus coracoideus district preferably to stick effect
Really, and can for being effective against shoulder mobility time produce and separate stress and provide the most fixing intensity with shear stress.
Open source literature also reports the internal fixation device of some scapulas at present, and through retrieval, we take passages such as
