Abstract
The invention discloses a movable joint spacer for infection after total knee replacement. The movable joint spacer for the infection after the total knee replacement is characterized by comprising a thighbone element and a shin bone substrate, wherein the thighbone element and the shin bone substrate are mutually connected in the manner of joint. The thighbone element and the shin bone substrate are respectively made of bone cement. A good amount of antibiotic is added when the thighbone element and the shin bone substrate are manufactured. The invention provides the movable joint spacer for the infection after the total knee replacement, which can be directly implanted into a knee joint by a surgeon because of reasons of septicopyemia or disinfection failure and can enable the knee joint to be movable and be high in strength.
Description
Technical field
The present invention relates to a kind of orthopaedics implant, be specifically related to a kind of knee prosthesis postoperative infection with movable property joint escapement.
Background technology
In for the orthopaedics replacement operation, the total knee replacement postoperative infection is the complication of the artificial knee joint replacement avoided of real difficulty, can cause mentally very large misery to the patient, cause very major injury on the health, the household causes very large worry, cause economically very large loss, also pose a big pressure also for simultaneously the doctor.At present, the method of total knee replacement postoperative infection treatment is: at first take out the thorough debridement of original prosthese, utilize the interim knee joint barrier bodies of containing of manual preparation of antibiotic bone cement piece conduct to place joint to carry out disinfection, after infection control, again insert new artificial knee joint.Utilize the bone cement piece of this manual preparation as interim knee joint barrier bodies, have Production Time length, can not make joint motion, and reduced the probability of again inserting new artificial knee joint successful surgery.
Summary of the invention
Deficiency for the prior art existence, technical problem to be solved by this invention is, provide a kind of to the surgeon owing to septicopyemia or sterilize when unsuccessfully waiting reason, can directly insert knee joint, and make knee joint have movable property, high-intensity knee prosthesis postoperative infection with movable property joint escapement.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of knee prosthesis postoperative infection is with movable property joint escapement, and it includes femoral and tibial base, and femoral is connected with articulated manner alternately with tibial base.
Above-mentioned knee prosthesis postoperative infection adopts bone cement to make with movable property joint escapement, described femoral and tibial base.
Above-mentioned knee prosthesis postoperative infection adds suitable antibiotic with movable property joint escapement during described femoral and tibial base are made.
Above-mentioned knee prosthesis postoperative infection is with movable property joint escapement, and described femoral and tibial base are fixed on the joint end with bone cement.
Above-mentioned knee prosthesis postoperative infection is to be shaped with the different sizes that are fit to any patient with movable property joint escapement, described femoral from tibial base.
Knee prosthesis postoperative infection of the present invention with the advantage of movable property joint escapement is:
1, knee prosthesis postoperative infection of the present invention meets body biomechanics with movable property joint escapement, uses gypsum mold moulding according to the prosthese form, meets human figure and as much as possible protects knee joint function in patients with knee.
2, knee prosthesis postoperative infection of the present invention has extraordinary economy with movable property joint escapement, and other similar operation costs are huge, cause huge economic loss to patient.
3, knee prosthesis postoperative infection of the present invention is with movable property joint escapement, and raw material is easily looked for, and manufacturing process is relatively simple, and is time saving and energy saving.
4, knee prosthesis postoperative infection of the present invention is with movable property joint escapement, utilize this joint escapement before again inserting new artificial knee joint, to keep suitable joint space for new artificial knee joint, reduce cicatrix, joint capsule soft tissue spasm and the useless property the used bone loss of generation interval between the two operations, and can carry out disinfection to infection place, and this joint escapement can provide articulation, improves Quality of Life.
Description of drawings
Fig. 1 is the perspective view of femoral of the present invention;
Fig. 2 is the perspective view of tibial base of the present invention;
Fig. 3 is the side view of user mode of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
As shown in Figure 1, 2, 3, a kind of knee prosthesis postoperative infection is with movable property joint escapement, and it includes femoral 1 and tibial base 2, the shape of femoral 1 approximate " U " shape, and the bottom has external contact face 6; Tibial base 2 approximate horseshoe-shaped shapes, the top has interior contact surface 5; External contact face 6 and interior contact surface 5 are through polishing, thereby the excellent surface with low-friction coefficient provides joint mobilization.
In use, the articular prosthesis that infects before the surgeon at first removes also cleans joint space, the femoral 1 of selecting again to be fit to patient's size is installed in the space of removing articular prosthesis with tibial base 2, the surgeon is fixed on femoral 1 bottom of femur 3 by bone cement, tibial base 2 is fixed on the top of tibia 4 by bone cement.Femoral 1 and tibial base 2 are connected alternately with articulated manner, the namely combination of external contact face 6 and interior contact surface 5, thus provide activeness to the joint.Femoral 1 and tibial base 2 adopt bone cement to make, and have added simultaneously an amount of antibiotic, play certain disinfective action.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, the variation of making, change, interpolation or replacement all should belong to protection scope of the present invention.
