Description
Technical field
The present invention relates to the prosthetic replacement field, more particularly, relate to a kind of artificial semi-pelvis prosthesis.
Background technology
Huge pelvic tumor or serious the damage are the common diseases of pelvis, because pelvic tumor or destruction focus are usually involved acetabular bone, and scope is huge, and operation usually needs to carry out half pelvis amputation.Traditional half pelvis amputation art (hemipelvectomy) is meant half side pelvis and the amputation in the lump of homonymy lower limb, also claim back 1/4th amputations (hindquarter-amputation), this will bring nonvolatil maimed person and serious mental maladjustment to patient.Along with the development of bone tumour therapy theory, protect the Comprehensive Treatment idea of limb and approved extensively that simple excision has half pelvis of tumor, i.e. Hemipelvectomy (internal hemipelvectomy) in the body, and keep patient's limbs.Behind the interior Hemipelvectomy, the reconstruction of pelvic ring becomes the key of recovering patient's lower limb function.After amputation acetabular bone and big portion or whole ilium, pubis and the ischium, the structure of half pelvis and hip joint and reconstruction are problems of difficulty especially at the same time.
Carrying out pelvis structural remodeling artificial prosthesis substitution's method commonly used at present has (1) internal fixation (as: Steinnmann nail, steel plate, screw etc.)+bone cement+bone grafting+overhaul type full hip-joint prosthese, carries out knockdown half pelvis and rebuilds; (2) restricted type hip joint tumor prosthese+from body fibula transplanting+limb shortening carries out the bear a heavy burden reconstruction of the line of force and function of joint of patient; (3) saddle-shape prosthese, the reconstruction of the line of force of under the situation of the reserve part ilium wing, bearing a heavy burden and function of joint; (4) artificial semi-pelvis prosthesis (Chinese invention patent ublic specification of application CN 101390781A) of split assembling, when the reconstruction operations of pelvis acetabular bone, according to acetabular bone amputation scope, adjust ilium parts and the angle between the acetabular bone parts and the installation of connector thereof of prosthese; (5) the computer assisted artificial semi-pelvis prosthesis (Vitallium of Germany
TMProsthese), carry out the reconstruction etc. of the pelvic ring and the heavy burden line of force, function of joint.
All there are many shortcomings in the existing common technology, using internal fixation (as the Steinmann nail)+bone cement+bone grafting+overhaul to carry out half combined pelvis with total hip prostheses as (1) rebuilds, need be in art according to the particular location of ilium, pubis and ischium, adjust the tram and the direction of acetabular bone, and occasional combination is installed in art, and the relative position of adjusting each parts satisfies the needs of dissecting coupling.And the position that can not see or touch offside pelvis and acetabular bone during the operator art is difficult to accomplish lateral symmetry.And the adjustment of prosthese position must be three-dimensional in the art, this makes borrowed structure obviously complicated, spare part quantity that is price significantly increase, and the bulk strength of prosthese and stability will suffer damage, operating time and difficulty also will increase, in the postoperative, the probability of prosthetic loosening at a specified future date, fracture, dislocation also obviously increases.(2) use restrictive hip joint tumor prosthese+from body fibula transplanting+limb shortening, be actually behind the Hemipelvectomy that disease is decreased, on improper hip joint position, laid the restricted type hip prosthesis, the bilateral hip joint is not in same level, and the obvious cripetura of affected limb, postoperative causes invalidity largely, difficulty in walking to the patient.(3) saddle-shape prosthese requires to keep enough iliums so that the saddle rest obtains the mechanics support, can not be used for time patient of complete or full ilium excision.And postoperative hip ranges is general all less than 50 °, and the patient can only partly sit, and more can not squat down.(4) artificial semi-pelvis prosthesis (Chinese invention patent ublic specification of application CN 101390781A) of split assembling, be difficult in art the correct three-dimensional position of adjusting each assembly and with the offside symmetry, between each assembly and engaging force and stability between skeleton be difficult to long term maintenance.(5) mechanical structure and the function of joint of the auxiliary artificial semi-pelvis prosthesis reconstruction of appliance computer Ipsilateral half pelvis are after carrying out the excision of half pelvis at present, rebuild the new technique and the developing direction of mechanical property and function of joint.Prosthese is made in area of computer aided processing, simple installation, and anchoring face is better with the accuracy and the operability of the locus of acetabular bone, as the Vitallium of Germany
TMProsthese, but still have much room for improvement aspect fixing in being connected of prosthese and remaining pelvis (ilium, rumpbone and pubis).
From mechanical stability, no matter be the artificial semi-pelvis prosthesis of prefabrication type artificial semi-pelvis prosthesis, split assembling at present, still also there is certain defective in general area of computer aided artificial semi-pelvis prosthesis in the connection site design of prosthese and remaining pelvis.After half pelvis amputation, particularly under the situation that ilium excises fully, prosthese is that the postoperative prosthese maintains a long-term stability with being connected of remaining pelvis, avoids the key factor of becoming flexible.After ilium excised fully, the junction point of semi-pelvis prosthesis and remaining pelvis mainly contained two places: 1. rumpbone.Generally prosthese and rumpbone fixedly is to rely on screw, prosthese and sacroiliac interfacial stress mainly are to shear or tensile stress, as patient down and when sitting up, and huge and loose shift that repeatedly shearing or tensile stress will cause prosthese, or screw loosening or fracture, finally cause the pelvis prosthesis displacement.2. pubis horizontal branch.Pubis horizontal branch superficial surface exists Femur blood vessel with neural, and dark face has obturator nerve (there is urethra in center line portion), can obviously influence the surgical exposure of horizontal branch and laying with fixing of prosthese, and operation technique is difficulty.At present general semi-pelvis prosthesis is all only fixed with bolt or screw, is difficult to bear toward the renaturation shear-type load.
Summary of the invention
