Description
Technical field
The present invention relates to a kind of device using bone to carry art treatment femur large segmental bone defect.
Background technology
Long bone large segmental bone defect be phalangeal fracture can not self-heal or only can regenerate 10% Cranial defect, be generally involve long bone diameter 2-3 doubly.Large segmental bone defect is caused by reasons such as High energy trauma, infection, tumors usually, and often stiff with limb shortening, deformity, osteomyelitis, amyotrophy and adjacent joints, its repairing and treating is one of the biggest problem of field of orthopaedics always.Showing according to statistics, is that patient the most often accepts one of front 50 kinds of treatments in German bone collection operation; Patient about 800,000 example of bone collection operation need be carried out every year in the U.S.; 3,000,000 examples have just been exceeded because wound needs row bone collection to perform the operation at the annual list of China; Large segmental bone defect gives patient and brings the injury of huge body and mind and financial burden, therefore how to solve the important topic that this difficult problem has become field of orthopaedics.
The main method of current clinical treatment long bone large segmental bone defect has autologous bone transplanting, Masquelet technology and Ilizarov technology.Autologous bone transplanting has best bone conduction, self-bone grafting and osteogenesis effect, is the standard for the treatment of Cranial defect.But autologous bone amount is limited, bone strength is not good enough, be difficult to the demand meeting large segmental bone defect.Although the bone collection of anastomosis of blood vessel (as fibula, ilium, rib etc.) is also the effective ways for the treatment of large segmental bone defect, but this operation wound is large, many for district's complication, bone graft completes moulding and to increase the thick time long, and patient can not early loading, easily there is stress fracture, amyotrophy etc. in the later stage.In addition, this technological learning curve is long, requires relatively high, can not be widely used in clinical to patient, is not therefore the main stream approach for the treatment of large segmental bone defect.The treatment appearing as large segmental bone defect of Masquelet technology provides a kind of new way.This technology is the autologous bone transplanting treatment Segmental Bone Defect utilizing film auxiliary.This technology is divided into two stages particularly.First stage: thoroughly clear rear implantation PMMA bone cement spacer, use internal fixtion or extenal fixation to be fixed, closed wound surface, is formed and induce film.Second stage: cut induction film after 6-8w, remove bone cement spacer, get through pulp cavity, fill autologous spongiosa bone in film, then closed induction film and otch.This induction film not only has to be avoided bone graft absorption, maintenance bone graft position and stops the effects such as soft tissue intrusion, and can secrete somatomedin and bone-inducing factor promotion bone tissue growth, as blood vessel endothelial factor, TGF-β 1, BMP-2 etc.Although multinomial clinical research proves that Masquelet technology treatment Cranial defect can obtain certain clinical effectiveness, also there is very large limitation.The maximum defect of this technology is to need a large amount of autologous bone transplantings in repairing bone defect process, adds operation wound and for district's complication; And this technology can not effectively correct limb shortening and the line of force, also need in conjunction with micro-flap technology if merge large area skin soft tissue defects.In addition, patient can not take exercise by early loading after surgery, easily occur the complication such as stress fracture, bone resorption and bone does not connect, and the method needs to carry out twice even Repeated Operation, and length of patient stay grows, it is high to spend.
The appearance of bone carrying technology is considered to 20th century orthopaedic milestone, and a New Times has been started in the treatment for Cranial defect.Bone carrying technology created by Russian orthopedist Ilizarov, and following the tension force-stress rule of tissue regeneration, meet " bone Natural Reconstruction " theory, is the goldstandard of current clinical treatment long bone large segmental bone defect.The core of bone carrying technology is to be divided into three steps particularly by the distraction osteogenesis of Ilizarov support: 1. use Ilizarov support to fix suffering limb, provide stability, maintain limbs length and the line of force; 2. the metaphysis of pair close Cranial defect carries out low-yield cortex osteotomy; 3. regulate Ilizarov support by activated for tool bone section according to suitable speed with frequency to the slippage of Cranial defect stump, draw close, and complete bone defect healing under Ilizarov support is fixed.Compare with Masquelet technology with autologous bone transplanting art, bone carrying technology has following advantage: 1) repairing bone defect length is unrestricted, does not need autologous bone transplanting, avoids the defect of autologous bone transplanting and Masquelet technology " with repair in trauma wound "; 2) this technology can stretching same period soft tissue regeneration, does not need to adopt skin flap transplantation to repair skin tissue defects; 3) cacomelia of various complexity is corrected the same period by support arm.4) belong to Minimally Invasive Surgery, curative effect is reliable, low cost.
Although the various complicated Cranial defect determined curative effect of bone carrying technology treatment, also there is more complication, and the use of these complication and Ilizarov support is closely related.At present for Ilizarov support mainly ring type exterior fixation bracket and the single pole exterior fixation bracket of bone carrying technology.Ring type exterior fixation bracket is three dimensions configuration, and fixed, stress distribution is even.This support needs to squeeze into several pieces of draw points on the two ends metaphysis and slippage bone block of long bone, to provide stable, maintains the effect of limbs length and the line of force.But wear many draw points in many planes sclerotin can be caused to cut, reduce local bone intensity, iatrogenic fracture may be caused; And when many planes penetrate draw point to operating technology require high, damage severely injured want neurovascular risk.The Ilizarov support fixed cycle is long, clinical care difficulty, therefore pin site infection, needle track loosen, fracture and Soft tissue cutting complication often occur.And some patients toleration is poor, easily there is the psychic problems such as anxiety, depression be even bigoted, also having some patients because of the lower ground weight training of the sense of discomfort such as limbs pain, swelling refusal, may there is the complication such as disuse osteoporosis, refracture, bone delay in healing even do not heal in the later stage.Single pole exterior fixation bracket has simple to operate, easy to carry, pin site infection is few and patient such as easily to tolerate at the advantage, is suitable for the Cranial defect that length is less.But single pole exterior fixation bracket mechanical stability is poor, cannot adjust the line of force, suffering limb can not early loading, and the complication such as the line of force is bad, disuse osteoporosis, refracture, bone delay in healing even do not heal can appear in the later stage.
