Description
Technical field
The present invention relates to a kind of fixture of Fracture of femur, belong to orthopedic medical device technical field.
Background technology
Femur is long bone the longest in skeleton, bear a heavy burden the heaviest bone, and body is antecurvature arc, in the 170o angle of cut between upper and lower femoral shaft axle, and inward turning reverses 30o, femoral bone cavitas medullaris has radian forward, large compared with outward appearance, especially in non-spongy bone district, the position that pulp cavity is narrower or outward appearance diameter is less, radian is larger, cortical bone is thicker, and femur non-spongy bone district axis radius of the radian is 90.2 ± 15.7cm, and femur rear muscle is attached with nervus vasculairs to be passed through.
Fracture of femur is comparatively common, accounts for 10% of whole body fracture, and in young patient, fracture of shaft of femur is high-energy damage and the mark of multiple injury normally.Methods for Distal Femoral Fractures often occurs in the youngster of high-energy damage, or the osteoporotic old people of low-yield damage companion, and Methods for Distal Femoral Fractures accounts for 6% of whole Fracture of femur.
Long tubular bone fracture is fixed with in early days and helps alleviating pain, reduces disability rate and mortality rate, shortens the hospital stays, reduces medical expense.The dry diameter of adult thighbone is less and muscle is abundant, and fracture method reset extenal fixation, can not keep good fracture reduction, often adopt internal fixation in clinical treatment.For reaching the absolute stability of fracture fixation, fracture end pressurization must be enough to all active forces (bending force, tension force, shearing force and rotating force) neutralizing whole fracture face.Steel plate screw is fixedly applicable to treat the shaft fracture involving metaphysis or have joint involvement.Intra-articular fracture needs anatomical reduction and absolute stability is fixed.The shaft fracture of long bone some be also the patient of accusing of very well of Interal fixation, some multiple injuries, Interal fixation is also the method being better than extenal fixation.Locking steel plate can make inner fixed stand, and steel plate can not contact with periosteum in theory, can reach relatively stable and protect blood fortune to the full extent, can make fracture that indirect knitting occurs rapidly.There is provided stress can be made along whole implants compared with the hold-down screw of stability evenly distribution, play the biomechanical function such as protection, pressurization, tension band, bridge joint, support of steel plate.
Normal femur is eccentric force, and outside is by stretching active force, and inner side, by pressurization power, can open, and inner side can be compressed outside fracture end.Outside crista femoris, using steel plate is fixed, if inner side cortex is complete, steel plate side can bear tension force, and fracture end is under pressure.The accurate Anatomical Reconstruction of condyle of femur of Methods for Distal Femoral Fractures is required, but to insert technical requirement higher for gusset, uses gusset that knee joint varus and rotation deformity easily occur.Dynamic condylar screw diameter is excessive, and bring bone loss and lay can not near distal femur, and LISS settles too far also can cause soft tissue problem.Therefore, how to adopt the reset and fixed mass that improve Fracture of femur, be still the difficult problem that current orthopedist is urgently to be resolved hurrily.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of femur rear internal fixtion blade plate, on rear side of this blade plate and femur, anatomic form is conformal, after femur, inner side or rear outside are inserted, on the pressure side fixing comparatively tension side is fixing is more conducive to union of fracture, femur full section fracture is made to obtain satisfied reset and fixedly secure, and can post-operative complication be reduced, improve clinical efficacy.
The technical scheme solved the problems of the technologies described above is:
A kind of femur rear internal fixtion blade plate, blade plate is elongate steel plate, blade plate bends at length direction, curved shape and the antecurvature radian of femur match, and blade plate bends at width simultaneously, and plate face and the femur rear side surface form of bending match, blade plate is alongst distributed with multiple screw, screw is diplopore syndeton, and diplopore is respectively locking screw and common screw, and blade plate also has multiple Kirschner wire fixation hole.
Above-mentioned femur rear internal fixtion blade plate, described blade plate is used for distal femur, and the lower end of blade plate has to the inside and/or the sweep in outside, to the inside and/or the sweep in outside respectively with the fracture medial condyle of femur and/or lateral condyle is corresponding connects.
Above-mentioned femur rear internal fixtion blade plate, described blade plate is used for distal femur, the component that the oriented inner side and outer side, lower end of blade plate is stretched out, and the component stretched out with outside is to the inside respectively with the condylus medialis femoris of fracture with lateral condyle is corresponding is connected.
The invention has the beneficial effects as follows:
The present invention designs according to femur anatomical structure and Bone fracture characteristics, for fracture is on the pressure side fixed, the cambered design that blade plate is and femoral surface fit tightly, be suitable for diverse location remain displacement and reset further and fracture fragments fixing, common lag screw is combined with locking nail, pressurization is fixing to be combined with tractive, achieves fabulous fixed effect.
The present invention is simple and reasonable, fixation, accurate positioning, flexibly simple to operate, replacement and fixation repeatedly can be reduced in art; Implant is simple, and reducing local soft tissue stimulates; Direction is flexible and changeable, can effective stable fracture fragment; Fixed, can early functional exercise, post-operative complication is few.
The present invention breaches traditional method be fixed from tension side before femur, it is the innovation to Fracture of femur Internal fixation technology, efficiently avoid conventional femoral operation shortcoming, solve the difficult problem do not solved for a long time, substantially reduce operating time and recovery time, effectively alleviate the misery of patient, there is good Social benefit and economic benefit.
