Description
Technical field
This utility model is related to technical field of medical instruments, more particularly to a kind of distal radius fracture reduction fixator.
Background technology
Radius far-end fracture refers to the fracture betided within distal aspect of the radius 3cm, is a kind of commonly encountered diseases of orthopaedics
And frequently-occurring disease, middle-aged and elderly people is more common in, especially old women, document report its sickness rate accounts for the 10-15% of extremity fracture；
With the arrival of Aged in China society, the patient of radius far-end fracture also increases therewith.
At present radius far-end fracture is in many classifying methods, the most commonly used be the fracture typing named with name and
AO/ASIF typings, are divided into section Le Shi, Smith, three kinds of barton's fracture with the radius far-end fracture that name is named, and it is focused on to bone
During folding, Injury mechanism etc. is described；A, B, C three types can be divided into by AO/ASIF typings, A, Type B are usually stability bone
Folding, c-type is unstable fracture, and AO/ASIF typings focus on after description fracture the complexity of fracture site displacement degree and many
Sample, has directive significance to clinical treatment.This apparatus primary treatment object is the c-type fracture patient in AO/ASIF typings.
For c-type radius far-end fracture (instability mode), modern medicine generally advocates operative treatment, but every kind of operation method
There is its weak point, there is anesthesia and operation risk, costly in addition, many patients, particularly middle-older patient are difficult to connect
By operative treatment.
1st, percutaneous pinning art percutaneous pinning art treatment radius far-end fracture, operation technique are easy, energy little to soft tissue injury
Fracture end blood supply is preferably protected, is conducive to union of fracture, has been provided simultaneously with the advantage of non-operative treatment and operative therapy, has fitted more
Fracture for A, Type B, but for c-type is fractured, percutaneous pinning art often occurs radial shortening in fracture healing process, causes lower chi
Oar joint disorders, affect wrist joint function.
2nd, the advantage of exterior fixation bracket exterior fixation bracket be simple structure, it is easy to operate, on fracture site blood supply affect
It is little, can early functional exercise etc..Its principle is the Retracting repositioning by ligament, under continuous tractive effort keeps muscle and tendon
Anxiety, forms tissue class clamping plate, and after keeping resetting, sclerite stablizes.To open fracture, unstability intra-articular fracture and
Metaphysis comminuted fracture is exterior fixation bracket treatment indication.To some complicated radius far-end fractures (c-type), give merely
Exterior fixation bracket can not obtain good fixed effect, generally give auxiliary using Kirschner wire and fix；Exterior fixation bracket is treated
Complication has pin tract infection, puts pin loosening etc., and costly.
3rd, the advantage of internal fixation internal fixation is under direct-view to reach sclerite as far as possible
To anatomical reduction and it is fixed, allow patient to carry out functional exercise early stage, reduce malunion etc..But during dorsal part approach by
Few are covered to aluminum alloy materials in distal radiuses dorsal part soft tissue, radius dorsal tubercle is not easy to putting for aluminum alloy materials sometimes
Put, the complication such as synovitis, adhesion of tendon and nerve injury often occur, in some instances it may even be possible to which blade plate fracture occurs.Volar approach is cut
It is the effective means for reaching anatomical reduction to open reset, but its complication also can not be ignored, and such as operation affects fracture site blood to follow
Ring, easily causes fracture delayed union, infection of incisional wound, inner fixer to release, and plants the bad screw of nail and is strayed into carpal joint etc., while fracture heals
The interior solid thing of taking-up of performing the operation again, patient is needed to be subjected to second operation and anesthetic risks after conjunction.
4th, it is the less invasive techniques for developing in recent years that carpal joint mirror treats radius far-end fracture under the guide of carpal joint mirror,
Carpal articular surface degree of impairment can directly be observed under bright-field by carpal joint mirror, be easy to intraarticular cleaning, ligamentum intraarticulare
The reparation of damage and sclerite replacement and fixation, repairing effect is more accurate, and soft tissue injury is less, remains fracture end blood
For.To some complicated radius far-end fractures, the inside and outside fixation for treatment of arthroscopic techniques joint is more advantageous, but because of the art formula
Requirement has carpal joint mirror and its arthroscopic techniques, therefore difficulty in clinical popularity.
5th, artificial joint for wrist's replacement, with the development of medical skill and prosthetic material designing and manufacturing technique, is carpal joint disease
The patient of trouble provide multiple choices method, current artificial joint for wrist's replacement not as good as hip joint, knee replacements like that into
Ripe, case load is less, and the problem for existing needs Long-term and further studies.
6th, for radius far-end fracture, non-operative treatment main method is manual reduction Gypsum Fibrosum or plintlet to non-operative treatment
Outer fixation.
Fixed with certain limitation outside Gypsum Fibrosum, carpal joint is stiff, and often occurs that fixation is too tight or too loose
Situation, easily causes the complication such as wrist pain, stiff and rear wrist joint function obstacle.
Set by small splints from outside treatment radius far-end fracture is classical Chinese medicine traditional remedies, is a kind of flexible fastening pattern, energy
Make carpal joint movable within the specific limits, be conducive to the regression of affected part swelling, and folder can be adjusted at any time according to limb swelling situation
Plate length and elasticity, can also be aided with Chinese medicine external application and fumigation and wash method, have some superiority compared with plaster fixing.
Manual reduction Set by small splints from outside treatment stable type radius far-end fracture (A, Type B), acceptance rate can reach 88% with
On.But for unstability radius far-end fracture (c-type), after fixing outside the reduction of the fracture, often there is the displacement situation of cripetura again.
Nesbitt etc. reports that the 50 unstability radius far-end fracture patients good to expectant treatment initial reset carry out close follow-up
Shi Faxian, treatment only have 46% patient and also maintain reset good enough, 54% patient to reset and lose after 4 weeks.In clinical studies,
Many scholars have found distal radiuses shortened deformity and carpal functional rehabilitation has high correlation, therefore find effectively anti-
Only after radius far-end fracture reset, the method for cripetura has positive meaning.
All the time, it is embedding to correct fracture by artificial free-hand traction that the traditional method of c-type radius far-end fracture resets
Insert and misplace, wherein key of the continuous traction for manual reduction, reset and fixation procedure through whole, during operation, at least need 2-
3 doctor's collaborations are completed, and operation is arduous, difficulty is larger, and patient is also painful, and can not be resetted under x-ray monitoring, Zhi Nengyi
Fracture site alignment situation is judged by the clinical experience of doctor, most cases are difficult once success, often need multiple handss
Method reduction could obtain inadequate result, have a strong impact on the quality and success rate of the reduction of the fracture, hinder manual reduction technology
Clinical practice and development.
In order to overcome the shortcomings of traditional treatment and operative treatment, author damages pathogenesis, treatment original according to radius far-end fracture
Then and combine clinical experience for many years design and have developed it is a kind of there is reduction by traction and fixing function, and can effectively prevent fracture multiple
" distal radius fracture reduction fixator " of secondary displacement behind position, expects it to radius far-end fracture and provides a kind of noninvasive, new
Treatment technology and equipment.
