Description
Technical field
This utility model is related to a kind of utilization bone and carries the device that art treats large segmental bone defect.
Background technology
Long bone large segmental bone defect is that phalangeal fracture is unable to self-heal or is only capable of regenerating 10% Cranial defect, is generally involved
2-3 times of long bone diameter.Large segmental bone defect is generally caused by reasons such as High energy trauma, infection, tumors, is often accompanied by limbs short
Contracting, deformity, osteomyelitis, amyotrophy and adjacent joints are stiff, and its repairing and treating is always one of the biggest problem of field of orthopaedics.
Show according to statistics, be that patient most often receives one of front 50 kinds of treatments in the operation of German bone collection；Bone shifting need to be carried out every year in the U.S.
The patient about 800,000 for planting operation；Chinese annual single because wound needs the operation of row bone collection just to exceed 3,000,000；Big section bone lacks
Damage gives patient and brings the injury of huge body and mind and financial burden, therefore how to solve the difficult problem and become the weight of field of orthopaedics
Want problem.
At present the main method of clinical treatment long bone large segmental bone defect have autologous bone transplanting, Masquelet technologies and
Ilizarov technologies.Autologous bone transplanting has optimal bone conduction, self-bone grafting and osteogenesis effect, is the mark for treating Cranial defect
It is accurate.But autologous bone amount is limited, bone strength is not good enough, it is difficult to meet the demand of large segmental bone defect.Although the bone collection of anastomosis of blood vessel
（Such as fibula, ilium, rib etc.）And the effective ways for the treatment of large segmental bone defect, but the operation wound is big, for area's complication
Many, bone graft completes moulding and to increase the thick time long, and patient is unable to early loading, and stress fracture, flesh easily occurs in the later stage
Meat atrophy etc..Additionally, the technological learning curve is long, patient is required of a relatively high, it is impossible to be widely used in clinic, therefore not
It is the main stream approach for treating large segmental bone defect.The treatment for appearing as large segmental bone defect of Masquelet technologies provides a kind of new way
Footpath.The technology is the autologous bone transplanting treatment Segmental Bone Defect aided in using film.The technology is specifically divided into two stages.The
One stage：Thoroughly clear rear implantation PMMA bone cement spacers, are fixed using interior fixation or outer fixation, close wound surface, shape
Into induction film.Second stage：Induction film is cut after 6-8w, bone cement spacer is removed, is got through pulp cavity, filled certainly in film
Body spongy bone, then closes induction film and otch.The induction film not only have avoid transplant bone resorption, maintain bone graft position and
The effects such as soft tissue intrusion are prevented, and can secrete somatomedin and bone-inducing factor promotion bone tissue growth, such as blood vessel endothelium
The factor, TGF-β 1, BMP-2 etc..Although multinomial clinical research proves Masquelet technologies, treatment Cranial defect can obtain certain
Clinical effectiveness, but there is also significant limitations.The maximum defect of the technology be need during repairing bone defect it is substantial amounts of
Autologous bone transplanting, increased operation wound and for area's complication；And the technology can not effectively correct limb shortening and the line of force,
If merging large area skin soft tissue defects to also need to reference to micro- flap technology.Additionally, patient can not bear in early days after surgery
Take exercise again, the complication such as stress fracture, bone resorption and bone does not connect easily occur, and the method need to carry out it is even many twice
Secondary operation, length of patient stay's length, cost are high.
It is considered as 20th century orthopaedic milestone that bone carries the appearance of technology, is that the treatment of Cranial defect is started
One New Times.Bone carries technology to be created by Russian orthopedist Ilizarov, it then follows the tension force of tissue regeneration-should
Force method then, meets " bone Natural Reconstruction " theory, is the goldstandard of current clinical treatment long bone large segmental bone defect.Bone carries technology
Core is the distraction osteogenesis of Ilizarov supports, is specifically divided into three steps：1. suffering limb is fixed using Ilizarov supports,
Stability is provided, limbs length and the line of force is maintained；2. the metaphysis of pair close Cranial defect carry out low energy cortex osteotomy；3. adjust
Ilizarov supports by active bone section according to appropriate speed and frequency to Cranial defect stump sliding, draw close, and
Ilizarov supports complete bone defect healing under fixing.Compare with autologous bone transplanting art with Masquelet technologies, bone carries skill
Art has the advantage that：1) repairing bone defect length is unrestricted, it is not necessary to autologous bone transplanting, it is to avoid autologous bone transplanting and
The defect of Masquelet technologies " with repair in trauma wound "；2) technology can same period stretching soft tissue regeneration, be not required to adopt skin
Lobe skin grafing and mending skin tissue defects；3) the various complicated cacomelias of support arm same period correction can be passed through.4) belong to minimally invasive
Operation, curative effect reliability, low cost.
Although bone carries technology treats various complicated Cranial defect determined curative effects, more complication is there is also, and these
Complication is closely related with the use of Ilizarov supports.The Ilizarov supports that technology is carried currently used for bone are mainly ring type
Exterior fixation bracket and single pole exterior fixation bracket.Ring type exterior fixation bracket is three dimensions configuration, and fixed, stress distribution is equal
It is even.The support needs to squeeze into several pieces of draw points on the two ends metaphysis and sliding bone piece of long bone, to provide stable, maintenance limbs
The effect of length and the line of force.But wear many draw points in many planes and sclerotin can be caused to cut, local bone strength is reduced, may
Cause iatrogenic fracture；And operating technology is had high demands when many planes penetrate draw point, damage and severely injured want neurovascular wind
It is dangerous.The Ilizarov support fixed cycles are long, and clinical care is difficult, therefore pin site infection, needle track loosen, fracture and soft tissue are cut
Cut complication Jing often to occur.And some patientss toleration is poor, easily there are the psychic problems such as anxiety, depressed or even bigoted,
Also there are some patientss because of the lower ground weight training of the senses of discomfort such as limbs pain, swelling refusal, the later stage is likely to occur useless property sclerotin and dredges
Pine, refracture, the bone delay in healing even complication such as disunion.Single pole exterior fixation bracket has simple to operate, easy to carry, pin
The advantages of road infection is less and patient easily tolerates, is suitable for the less Cranial defect of length.But single pole exterior fixation bracket mechanics
Stability is poor, it is impossible to adjust the line of force, and suffering limb is unable to early loading, and the later stage may occur in which the bad line of force, again disuse osteoporosis, bone
Folding, the bone delay in healing even complication such as disunion.
