Description
Technical field
Type of the present invention belongs to medical instruments field, be specifically related to a kind of with memorial alloy be material make for the internal fixation device during fracture of the position 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 day by day common in recent years, accounts for 3% ~ 5% of shoulder fractures, and close to 1% of whole body fracture, fracture of coracoid process of scapula accounts for 3% ~ 13% of fracture of scapula.The anatomy relationship of processus coracoideus complexity makes its effect at shoulder particularly important.Previously there is the sequela such as the situation of shoulder joint shakiness and upper extremity function generation obstacle in expectant treatment again after having certain probability to cause union of fracture.Along with patient required day by day to improve to quality of life, after fracture, good functional rehabilitation becomes the emphasis that patient pays close attention to., there is comparatively multi-method and arguement at present clinically in fixing for fracture of coracoid process of scapula.Want to obtain good functional rehabilitation, except for except surgical indication, more and more tend to adopt operative treatment, object is all recover the stability of processus coracoideus.And be the key of performing the operation to the research of processus coracoideus anatomical structure.It is not only a dissection identification point of shoulder, plays very important effect in shoulder diseases.It rises near scapula exterior angle, there is the anatomical structure of complexity around: be positioned at 1/4 handing-over below coracoclavicular ligament outside clavicle coupled, processus coracoideus has coracobrachialis, coracoradialis and pectoralis minor to adhere to, and coracoacromial ligament medial extremity and coracohumeral ligament are attached to the lateral border of processus coracoideus.It is the important feature forming shoulder joints stability and function.Processus coracoideus is called as shoulder anterior " beacon ", has following 3 basic functions: 1. numerous muscle (or tendon) and ligament depend on a little, 2. maintain the stability of shoulder joint front upper part, 3. form that shoulder is upper suspends the indispensable part of complex in midair.But it is less to the basic research of processus coracoideus at present, from bibliographical information, Feng irrigates monarch etc. and carries out anatomical Observation to 27 adult's processus coracoideuses respectively, slide gauge and the steel ruler such as Yang Huifeng carry out anatomic measurement to 20 routine adult normal's shoulder joint specimen coracohumeral ligaments, because of needs obduction, number of cases is few.It only to measurement and the assessment clinical meaning of processus coracoideus or coracohumeral ligament, lacks systematic study to processus coracoideus district.Previously it has been generally acknowledged that and mostly can obtain good efficacy through expectant treatment.But a lot of scholar's retrospective study finds that expectant treatment can remain many sequela.Increasing scholar has been familiar with the importance of surgical operation therapy.Along with patient required day by day to improve to quality of life, after fracture, good functional rehabilitation becomes the emphasis that patient pays close attention to.Want to obtain good functional rehabilitation, except for except surgical indication, more and more tend to adopt operative treatment, object is all resume stability.
Scapula is one piece of irregular triangle flat bone, before slightly recessed, point two face three edge.Neck of scapula is narrow, and sclerotin is weak, and easily fracture, its stability relies on the integrity of three posts, if fracture is failed to pinpoint a disease in diagnosis, easily causes malunion of fracture, glenohumeral instability can be caused to determine or dislocation.Scapula is a part for shoulder suspention complex, connects upper limb and axial bone, has to enrich muscle and hold around it, is also starting point and the attachment point of polylith muscle.Accurate Diagnosis fracture of scapula, has important value to selection therapeutic scheme and the prognosis of the assessment state of an illness.Because scapula taxonomic hierarchies is comparatively complicated, there is no unified criteria for classification at present.Common sorting technique has Hardegger typing, Mille typing and international internal fixtion EASD (AO)/bone wound orthopaedics association of the U.S. (OTA) typing.Hardegger typing: specifically can 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.Current most scholar thinks to the fracture of scapula especially positive operative treatment of some serious displacement type fracture of scapula row, and the shoulder dysfunction that can to a certain degree exempting expectant treatment and cause, is more conducive to its functional rehabilitation.For the fracture of scapula having displaced, previously conventional employing expectant treatment, usually causes traumatic arthritis, pain, the serious sequela such as limitation of activity; Adopt open reduction and Kirschner wire fixation, because topography is complicated, wound is large, surgical technic requires high, post-operative recovery is also difficult to reach ideal effect.Fracture of scapula more after, depend on the one hand the degree of injury of fracture, on the other hand and operation well reset and be fixed with substantial connection.Just when coming to see, the material category selected of internal fixation treatment is many, reconstruction plate, T steel plate, deformed steel flats, calcaneal steel plate and Kirschner wire, steel wire, Absorbable rod and nonabsorable screw.The geometric shape of scapula is very irregular, and anatomical position compared with dark, attachment muscle is many, therefore, has the probability of raw nonunion more occurred frequently; Moreover internal fixation material need be considered to bear unnecessary misery to exempt patient's Repeated Operation from the permanent angle inserted as far as possible.Comprehensive two aspect factors are considered, titanium alloy material is not only the metal with higher inertia, and plasticity is very strong, there is good biocompatibility, both can reduce thus insert rear to tissue produce too much pessimal stimulation, again can be fully moulding to guarantee to produce with processus coracoideus district to stick effect preferably, and can for producing separation stresses when effectively resisting shoulder mobility and shear stress provides sufficient constant intensity.
