Abstract
The invention relates to a bone fixation plate, in particular to a humeral far-end posterior-lateral double-column fixing and locking bone fixation plate. The humeral far-end posterior-lateral double-column fixing and locking bone fixation plate comprises a steel plate head portion, a steel plate rear portion main body, a steel plate front flank and a steel plate rear flank. The humeral far-end posterior-lateral double-column fixing and locking bone fixation plate is mainly used for treating a humeral low-section fracture and a far-end humeral intercondylar fracture by attaching the outline of a steel plate to the humeral shaft and a humeral far-end and outer side edge anatomy in form. The whole attachment of the outline of the steel plate and the humeral shaft and the humeral far-end and outer side edge anatomy in form originally needs multiple steel plate or a combined reconstructed steel plate, but now the whole attachment can be achieved only by needing one steel plate, and the fixing effect is very good. In addition, anatomic attached flanks turned in an arc shape are smooth, radial nerve irritation probability is low, and the humeral far-end posterior-lateral double-column fixing and locking bone fixation plate is especially suitable for humeral lateral approach and 'Triceps Hemi-peel Approach' suggested and selected by surgeons at present.
Description
Technical field
The present invention relates to a kind of blade plate, particularly relate to twin columns fixedly locked blade plate in outside after a kind of distal humerus.
Background technology
The humeral shaft entirety of people is in cylinder sample, far-end is divided into humerus inside and outside collateral, the fan that form is flat and wide, the angle that leans forward is there is with shaft of humerus axis, and humerus condyles is thinner, easily to send out on hypomere fracture in supracondylar fracture of the humerus, humerus, intercondylar fracture of the humerus, the concurrent condyle of humerus of intercondylar fracture of the humerus or hypomere fracture in humerus.For many years, many hospitals adopt Y shape steel plate treatment fracture of the humeral condyle.The steel plate of this likeness in form English " Y ", once played historical action, also rear this type of patients many are controlled, but along with passage of time and technological progress, found by Follow-up After, there are the following problems for Y shape steel plate: 1) operation separation exposure triceps brachii scope is many, and wound is large, sclerite is lost blood confession, affects union of fracture; 2) steel plate needs moulding, extends operating time; 3) disconnected plate rate is high, and it is moulding that Y shape steel plate is convenient to operative doctor, and the material manufacture that producer's multiselect intensity is little, hardness is low, easily fractures; Meanwhile, biomechanics fixed difference, nonunion, long-term stress effect causes fatigability to fracture.Somebody devises distal humerus medial and lateral locking bone fracture plate and is applied to clinical, there is soft tissue on exposure damage ulnar nerve and sclerite and peels off too much, the problems such as fracture delayed union.In addition, this two block plate combines and is mainly used in treating fracture of the humeral condyle, is difficult to treatment fracture of the humeral condyle and humeral shaft fracture, lesion of lower segment of humerus fracture etc.At present, lesion of lower segment of humerus fracture needs double steel plate to fix clinically becomes common recognition, and multiselect combines one piece of reconstruction plate with one block of dissection plate or two pieces of reconstruction plates are fixed, it is large that this kind of method steel plate takies volume, fixing difficulty, the soft tissue on easy sclerite is peeled off too much, affects union of fracture; Reconstruction plate needs surgical doctor again moulding simultaneously, causes operating time to extend problem.In addition; when the humerus lateral approach that surgeon selects to praise highly at present, " Triceps Hemi-peel Approach "; appear and protect radial nerve for excellent (radial nerve after humeral shaft outside; distance capitulum of humerus top far-end 6 ~ 16cm; average out to about 12cm), original internal fixation material can not meet completely reforms needs at present.
Summary of the invention
The object of the invention is: the deficiency existed for prior art, provides a kind of anatomical features meeting humerus, twin columns fixedly locked blade plate in outside after effectively fixing distal humerus.
For realizing the object of the present invention, be achieved by the following technical solutions:

As preferably, the bore dia of the lock hole of described steel plate head and the front side wing is 2.7mm.
As preferably, the bore dia of first described large lock hole is 3.5 ~ 4.5 mm, other for bore dia be 3.5 mm.
As preferably, the screw that the large lock hole of first of described rear portion flank inserts is aimed at epitrochlea condyles and the steel plate rear portion trunk body longitudinal axis to be partial to far-end be angle δ is 40 ° ~ 50 ° angles, is 20 ° ~ 35 ° with trunk body axis oriented normal direction, the steel plate rear portion oblique angle γ that turns forward
As preferably, the angle α between described trunk body axis, humerus steel plate rear and the axis of described humerus steel plate head is 15 °.
As preferably, the angle β formed between described steel plate posterior area of fixigena and humerus trunk body axis is 55 ° ~ 65 °, and distance humerus steel plate head top distance is 50 ~ 60 mm, and the width of flank is 5.5 ~ 6.5mm, and length is 50 ~ 70mm
As preferably, described steel plate rear portion trunk body and described steel plate posterior area of fixigena are also provided with a gram formula pin hole.
As preferably, the arc shape that on front side of described steel plate rear portion trunk body, described steel plate head, described steel plate, the wing and described steel plate posterior area of fixigena and humeral shaft, distal humerus and two lateral border radians match.
As preferably, the material of described blade plate is steel or titanium alloy sheet.
Compared with prior art, the invention has the beneficial effects as follows: by profile and the humeral shaft of steel plate, the laminating of distal humerus and lateral border anatomic form, be mainly used to treatment lesion of lower segment of humerus fracture, and distal humerus Intercondylar fracture, mainly increase humerus posterior area of fixigena, that is done by flank is larger, use large lock hole, multi-angle direction is fixed from the side, wherein one piece of special screw is selected to fix distal humerus ulnar side post, other screw selectivitys fix humeral shaft, so just can be fixed, the profile of overall laminating steel plate and humeral shaft, distal humerus and lateral border dissect laminating, originally needed plurality of steel plates or with associating reconstruction plate, only need this block plate just can accomplish now, and fixed effect is very good.Meanwhile, the flank of dissection laminating, arcuation turnover is smooth, and the probability of excitation radial nerve is little, particularly applicable when surgeon selects the humerus lateral approach of high praise at present, " Triceps Hemi-peel Approach ".
