Description
Technical field
It is long suitable for clinic the present invention relates to a kind of artificial prosthesis of the adjustable overlapping attachment structure in long bone backbone portion
Bone backbone portion defect reconstruction technical field, it is to be related to long bone of limbs to include humerus, ulna, radius, femur, shin specifically
The primary or metastatic tumo(u)r excision Limb preservation of bone etc., the bone-culting operation institute such as Cranial defect, severe infections osteomyelitis after severe trauma
Caused by the artificial prosthesis rebuild of the structural Cranial defect in long bone backbone portion.
Background technology
With the progress and development of medical consultations technology, limb-sparing surgery turns into the main flow treatment side of malignant bone tumor at present
Method;Meanwhile structural Cranial defect caused by the factor such as severe trauma, infection be also required to carry out bone tissue rebuild could recover limbs
Function.Bone tumour can occur at each position in theory, and long bone of limbs be malignant tumour late period common metastasis site it
One, according to the difference of happening part, the design and use method of prosthese is also not quite similar.The current research to prosthese mainly collects
In knee, hip etc. larger weight-bearing joints, and these large joint prostheses applied in clinic it is relatively broad, and for four limbs
The prosthese in long bone backbone portion is few compared with in-depth study.Limb preservation becomes as the main development of current four limbs bone tumour therapy
Gesture, due to the pathological change of bone tumour occupancy so that be difficult the markings for finding contraposition after knurl section resected bone, so key portion
Usually there is the rotation deformity of limbs in bone tumour prosthese art after rebuilding, and is difficult to correct in the later stage, causes the long-term function barrier of patient
Hinder.Long bone backbone portion prosthese research and development at present relatively lags behind, as shown in Figure 5 and Figure 6, the vacation of the long bone backbone of prior art
Body is to use cement reaction mode mostly, and its remote, proximal shank portion is cement reaction mode, needed in art by it is remote, near-end is key
Injection bone cement in pulp cavity, is inserted into remote, near-end handle, and prosthese just can obtain preferable stability, art after bone cement solidification
Limb function can be recovered in short term afterwards;But when using cement reaction, the operation requirement inserted to prosthese is higher, general to require
" disposable accurate " inserts prosthese, and before bone cement is fully cured prosthese and host bone must be maintained to be relatively fixed, because
For bone cement once solidify, prosthese is difficult to be adjusted again, and if bone cement solidification before repeatedly regulation prosthese position or
Fail to maintain if prosthese and host bone be relatively fixed, the stability of prosthese will be reduced, it is easy to cause prosthese early stage to loosen,
The appearance of the complication such as abjection, sedimentation.In addition, cement reaction mode has the risk that bone cement disease occurs, i.e. bone cement is planted
Include a series of clinical conditions such as low blood pressure, arrhythmia cordis, hypoxemia, myocardial infarction, bleeding, asthma attack caused by after entering
Shape, cardiac arrest incidence is 0.5%~10% in bone-cement type total hip arthroplasty, and fatal rate is 0.6%~1.0%.Together
When, in cement reaction mode, prosthese crash rate at a specified future date it is higher, failure mode is mainly shown as mechanicalness aseptic loosening, disconnected
Split, dislocate, surrounding bone dissolving, fracture etc., wherein the sterile loosening problem of mechanicalness is the most prominent, and document report incidence is up to
30.6%~42.7%.As can be seen here, the prosthese service life of cement reaction is relatively short, and the second phase after prosthese failure overhauls hand
Art is nearly unavoidable, and some cases even need row Repeated Operation to solve problem, and the prosthese of cement reaction its
The difficulty of prosthese revision procedure is larger, complication is more, and postoperative effect is bad, disability rate is higher.For some expection survival periods
Longer young Patients with Bone Tumor, be particularly not suitable for by the way of cement reaction.Likewise, in severe trauma and infection
Etc. also usually needing in the case of long bone of limbs cadre Cranial defect caused by reason key portion's prosthese to carry out bone tissue reconstruction, use
These drawbacks similarly be present in cement reaction mode.
Although more far short of what is expected than the effect of cement reaction using the prosthese initial stability of biological fixation mode, due to life
The prosthese that thing is fixed has good osteoinductive and Integrated implant in itself, can effectively improve in prosthese, stability at a specified future date,
Extend the prosthese life-span, lower the related mechanical complications of prosthese, therefore this fixed form of biological fixation is increasingly by patient
Received with doctor, and one of the focus studied at present and direction.
The content of the invention

The artificial prosthesis and application method of attachment structure, this prosthese, which is that guarantor's limb of long bone of limbs backbone's tumor patient is more suitable, to be controlled
Treatment scheme.Fixed form is changed to more suitable biological fixation mode by the prosthese of the present invention.Although biological fixation mode is initial
Stability is poorer than cement reaction, but the later stage, its stability can gradually step up with Bone Ingrowth degree, wherein, stability at a specified future date
Be substantially better than cement reaction effect, compared with the prosthese of cement reaction, in the prosthese of biological fixation, long term complication it is few,
Service life is grown, and prosthese revision procedure is easily a lot.Avoid simultaneously in art using the bone water caused by bone cement
The generation of mud disease, the security of operation is improved, reduce the risk of death.
