Description
Technical field
The present invention relates to a kind of device that art treatment femur large segmental bone defect is carried with bone.
Background technology
Long bone large segmental bone defect is that fracture of finger is unable to self-heal or is only capable of the Cranial defect of regeneration 10%, 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, tumours, and it is short to be often accompanied by limbs
Contracting, deformity, osteomyelitis, muscular atrophy 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, German bone collection operation be patient most often receive before 50 kinds treatment one of；Bone shifting need to be carried out every year in the U.S.
Plant the patient about 800,000 of 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 huge body and mind injury and financial burden, therefore how to solve the weight that this problem has turned into 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 osteoacusis, self-bone grafting and ostosis 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 meets the needs of large segmental bone defect.Although the bone collection of anastomosis of blood vessel
（Such as fibula, ilium, rib）And the effective ways for the treatment of large segmental bone defect, but the operation wound is big, for area's complication
More, bone graft completes moulding and thickening time length, and patient is unable to early loading, and stress fracture, flesh easily occurs in the later stage
Meat atrophy etc..In addition, the technological learning curve is grown, of a relatively high is required to patient, it is impossible to clinic is widely used in, therefore not
It is the main stream approach for treating large segmental bone defect.The appearance of Masquelet technologies provides a kind of new way for the treatment of large segmental bone defect
Footpath.The technology is the autologous bone transplanting treatment section Cranial defect using film auxiliary.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 the surface of a wound, shape
Into induction film.Second stage：Induction film is cut after 6-8w, bone cement spacer is removed, gets through pulp cavity, is filled certainly in film
Body cancellous bone, then close induction film and otch.The induction film not only have avoid transplant bone information, maintain bone graft position and
The effects such as soft tissue intrusion are prevented, and can secrete growth factor and bone-inducing factor promotion bone tissue growth, such as blood vessel endothelium
The factor, TGF-β 1, BMP-2 etc..It is certain that although multinomial clinical research proves that Masquelet technologies treatment Cranial defect can obtain
Clinical effectiveness, but there is also significant limitations.The defects of technology maximum, is to need largely during repairing bone defect
Autologous bone transplanting, add operation wound and supply area's complication；And the technology can not effectively correct limb shortening and the line of force,
If merge large area skin soft tissue defects to also need to combine micro- flap technology.In addition, patient can not bear in early days after surgery
Take exercise again, the complication such as stress fracture, bone information and bone nonunion easily occur, and this method needs progress even more twice
Secondary operation, length of patient stay is long, it is high to spend.
The appearance that bone carries technology is considered as the milestone of 20th century orthopaedic srugery, is started for the treatment of Cranial defect
One New Times.Bone, which carries technology, to be created by Russian orthopedist Ilizarov, it then follows the tension force of 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, maintains limbs length and the line of force；2. the metaphysis of pair close Cranial defect carries out low energy cortex osteotomy；3. regulation
Active bone section is slid, drawn close by Ilizarov supports according to appropriate speed with frequency to Cranial defect stump, and
Ilizarov supports fix lower completion bone defect healing.Compared with autologous bone transplanting art and 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, avoid autologous bone transplanting and
The defects of Masquelet technologies " with wound repair wound "；2) technology can same period stretching soft tissue regeneration, be not required to use skin
Valve skin grafing and mending skin tissue defects；3) various complicated cacomelias can be corrected by the support arm same period.4) belong to minimally invasive
Operation, curative effect is reliable, low-cost.
Although bone carries technology treatment, various complicated Cranial defects are curative for effect, there is also more complication, and these
Complication and the use of Ilizarov supports are closely related.The Ilizarov supports that technology is carried currently used for bone are mainly ring type
Exterior fixing rack and single pole exterior fixing rack.Ring type exterior fixing rack 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 both ends metaphysis of long bone and sliding bone piece, to provide stable, maintenance limbs
The effect of length and the line of force., may but wearing more draw points in more planes can cause sclerotin to cut, and reduce local bone strength
Cause iatrogenic fracture；And high is required to operating technology when more planes penetrate draw point, damage and severely injured want neurovascular wind
It is dangerous.The Ilizarov support fixed cycles are grown, and clinical care is difficult, therefore pin site infection, needle track are loosened, fracture and soft tissue are cut
Complication is cut often to occur.And some patientss tolerance is poor, easily there are anxiety, depression or even the psychic problems such as bigoted,
Also there are some patientss because the senses of discomfort such as limbs pain, swelling refuse the weight training of lower ground, the later stage is likely to occur to give up and dredged with property sclerotin
Pine, refracture, the bone delay in healing even complication such as disunion.Single pole exterior fixing rack has simple to operate, easy to carry, pin
The advantages that road infection is less and patient is easily resistant to, is suitable for the less Cranial defect of length.But single pole exterior fixing rack mechanics
Stability is poor, can not 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.
