Abstract
The present invention provides one kind of femur proximal end socket jointing repair prosthesis. One cylindrical prosthesis has one femur neck prosthesis to be connected to the femoral head prosthesis of the broken original prosthesis and one locking hole. The femur neck prosthesis in raised arm shape is connected integrally to the cylindrical prosthesis. The present invention for repairing prosthesis has the advantages of simple operation, reduced operational complications, low cost, etc.
Description
Technical field:
The present invention relates to medical science, relate to pseudocolloid more specifically.
Background technology:
Customization tumor prosthetic replacement has become the important method of protecting bone tumour resection reconstruction in the limb art at present.The carrying out of increasing tumor prosthetic replacement operation, the prolongation of prosthese service time, the same with general artificial prosthesis substitution, complication such as infection, loosening, prosthese fracture have also appearred in the tumor prosthetic replacement.
The incidence rate of customization tumor prosthese fracture is 2.2%-5.8%, and the document of following up a case by regular visits to a large amount of customization tumor prostheses all is reported in the prosthese that the prosthese fracture generally all will more renew when overhauling both at home and abroad.Outside the outside distribution of the marrow business of customization tumor prosthese, rupture, the prosthese body has sufficient length, and the intact not loosening case that takes place of part in the pulp cavity, remove earlier the bone cement unusual difficulty of prosthese of fixation again in the overhaul technology, overhauling the same with common bone-cement type artificial prosthesis is one of difficult point in the revision procedure.Though overhaul the taking-up that technology such as middle Glassman, Cameron, Sydney etc. recommend to adopt that greater trochanter prolongation osteotomy, femoral shaft osteotomy and femoral cortex are windowed are assisted prosthese and bone cement at common prosthese, but generally need special instrument, complicated operation, require doctor's technical merit height simultaneously, the generation probability of complication such as fracture, osteotomy disunion, infection increases, and this step operation was difficult more when customization tumor prosthese was overhauled.Because handle is very long in the fixed marrow of customization tumor prosthese bone cement, the working place is narrower and small in the more metaphyseal marrow of backbone simultaneously.Fracture, the probability of complication such as osteotomy disunion is higher.The remaining bone amount is less behind the tumor prosthetic replacement, and it is more thorny to handle various complication, is catastrophic consequence sometimes, and patient has to carry out amputation.For patient, operating time is long, wound is big, it is slow to recover, cost is high, and patient can't bear high prosthese expense and abandoning cure sometimes.The tumor prosthese is overhauled generally and will be fixed with bone cement once more, and the combination degree at bone and bone cement interface reduced when the fixed prosthese of bone cement was overhauled once more with bone cement fixedly.Dohmae etc. had once measured the shearing force at corpse bone-bone cement interface, found that the stress value behind the overhaul technology is 20.6% of a first THR postoperative, and the stress value behind the overhaul technology only is 6.8% of a first THR postoperative for the second time.A large amount of early stage bibliographical informations have very high complication and revision rate again with the fixed prosthese of bone cement in overhaul technology, its again revision rate in 5 years follow up a case by regular visits near or reach 40%.
In sum, the fracture of customization tumor prosthese is the problem that we are more and more facing.Its revision procedure difficulty is big, and cost is high, and complication is many, and effect is not good enough.Jointing repair prosthesis design aspect in the prosthese fracture lacks simply, easily goes the prosthetic designs that clinical effectiveness is good.
Summary of the invention:
Purpose of the present invention is intended to overcome the deficiencies in the prior art, provides a kind of femur revision procedure simple, easy row, reduces complication in the art, and operating time is short, and patient trauma is little, recovers soon the femur proximal end socket jointing repair prosthesis that expense is low.
Purpose of the present invention can realize by following technical measures:
Barrel-shaped cylinder prosthese is connected with the neck of femur prosthese that links to each other with the femoral head prosthesis of former fracture prosthese, on the barrel-shaped cylinder prosthese lock hole is arranged.
Purpose of the present invention also can realize by following technical measures:
Described neck of femur prosthese is protruding arm shape and is connected as a single entity with barrel-shaped cylinder prosthese.
Get 1/2 or 1/3 of former scalpel edge and cut, only appear the fracture location of prosthese.Take out the part of the prosthese of fracture, barrel-shaped cylinder prosthese and the outer part socket of the residual marrow of fracture prosthese with socket jointing repair prosthesis are connected with the locking nail fashion of extrusion with the bone cement bonding.
The outside distribution of the marrow business that the present invention is directed to customization tumor prosthese is ruptured outward, the residual body of prosthese has sufficient length, and part is intact in the pulp cavity, bone cement fixation and the case that is difficult to take out, invented femur socket joint type jointing repair prosthesis, this prosthese is the same with former prosthetic material.This prosthese divides two parts, and a part is barrel-shaped cylinder prosthese, and diameter is greater than the outer part of the marrow of the prosthese that ruptures, and the outer part of marrow that can directly be enclosed within the fracture prosthese also is connected and fixed with bone cement and locking nail; Another part is the neck of femur prosthese that links to each other with the femoral head prosthesis of former fracture prosthese.
The application of various measures such as new adjuvant chemotherapy makes 5 years survival rates of malignant bone tumor guarantor limb patient reach 50%-60%.The tumor prosthesis replacement has become the important operation of protecting the limb art.A new selection and the theory of providing of overhauling of prosthese fracture is provided in the use of socket jointing repair prosthesis.This socket joint type prosthese has been compared following characteristics with the traditional tumour prosthese method of overhauling: 1. easy and simple to handle, only expose prosthese fracture place, directly with bone cement with new prosthese and former prosthese socket and strengthen fixing with locking nail, simplified operation process greatly, surgical technic requires low, shortened the operating time, made revision procedure simple; 2. need not to take out in the pulp cavity with the fixed prosthese handle of bone cement, overcome that bone cement and prosthese take out the process various disadvantages as fracture, osteotomy disunion etc. in traditional overhaul technology; 3. operation need not appear prosthese part in the marrow that thigh is done, and otch is short, and patient trauma is little, recovers fast, can carry out functional exercise in early days, and limb functional recover is good; 4. reduced the occurrence probability of the complication such as infection of prosthese overhaul technology; 5. the expense of prosthese has only half of traditional jointing repair prosthesis, and patient's medical expense is reduced greatly.
Be described further with reference to the accompanying drawings:
Fig. 1 is the sketch map of the embodiment of the invention; Barrel-shaped cylinder prosthese 1 is connected with the neck of femur prosthese 4 that is protruding arm shape that links to each other with the femoral head prosthesis of former fracture prosthese, on the barrel-shaped cylinder prosthese 1 lock hole 2 is arranged.
Fig. 2 be the former prosthese body 6 that connects femurs 8 by handle in the marrow 7 with the femoral head prosthesis 9 of former fracture prosthese for being connected the sketch map that capital neck of femur ruptures.
Fig. 3 is the user mode sketch map that Fig. 1 and former prosthese body 6 are connected and fixed by bone cement 5.
