Abstract
The invention discloses an artificial hip joint prosthesis handle for treating a periprosthetic fracture, and belongs to the technical field of orthopaedics medical apparatuses. The artificial hip joint prosthesis handle is used for treating the periprosthetic fracture generated after hip joint replacement. According to the technical scheme, a plurality of fixing holes are formed in the middle section and the distal end of the prosthesis handle and penetrate through the prosthesis handle from the outer side of the prosthesis handle to the inner side of the prosthesis handle, the length center lines of the fixing holes are perpendicular to the length direction of the prosthesis handle, and the multiple fixing holes are parallel. According to the artificial hip joint prosthesis handle, the fixing holes are reserved in the prosthesis handle, when the periprosthetic fracture generated after hip joint replacement is treated, a doctor can only use plate fixation, and cerclage wiring fixation is avoided. Steel plate fixing screws can penetrate through the reserved fixing holes to be fastened to an inner cortex and an outer cortex on the periphery of the femoral fracture, the good fixing effect is achieved, and mechanical stability is greatly improved. The artificial hip joint prosthesis handle is simple in structure and convenient to use; the fracture portion on the periphery of the prosthesis handle is stably and firmly fixed, the ideal operation effect is achieved, and recovery and functional recovery of a patient are quite facilitated.
Description
Technical field
The present invention relates to a kind of artificial hip prosthesis' handle for treating hip replacement Periprosthetic fracture, category
In orthopedic medical device technical field.
Background technology
In person in middle and old age's orthopedics patient, with hip joint disease significant proportion is occupied, wherein mainly a variety of causes draws
The caput femoris necrosis for rising and the fracture of neck of femur caused because of tumble.It is continuous with the improvement of people's living standards and health idea
Strengthen, patient carries out hip replacement quantity and is continuously increased, be that thorough radical curing of disease and recovery hip joint function are provided most preferably
Treatment means.But, with the increase of hip replacement quantity, the incidence of postoperative Periprosthetic Fracture After Total Hip Arthroplasty also significantly increases
Plus, caused by the external force such as its reason is mostly tumbled, falls, postoperative Periprosthetic Fracture After Total Hip Arthroplasty along with very high disability rate and other
Serious consequence, needs treatment in time.There is the fracture in femoral stem distal end in clinically common Periprosthetic fracture, this
The fracture of type is also the difficult point of clinical treatment.Because patient mostly is the elderly, typically all merge osteoporosis, therefore clinically
More wirerope cerclage is combined using steel plate and fix operative treatment, but because prosthesis handle is in the occupy-place of near end of thighbone pulp cavity, steel plate is solid
Timing can only insert mono cortex screw, have impact on the stability of Interal fixation, and be fixed using wirerope cerclage, certainly will affect corresponding
The blood fortune at position, therefore, surgical effect is not satisfactory.
The content of the invention
The technical problem to be solved is to provide a kind of artificial hip prosthesis' handle for treating Periprosthetic fracture,
This prosthesis handle can be used not only for first artificial hip joint replacing, and during suitable for fracturing around artificial hip prosthesis
Successive treatment, make fracture site fixation, stable, reach preferable surgical effect.
Solving the technical scheme of above-mentioned technical problem is：
A kind of artificial hip prosthesis' handle for treating Periprosthetic fracture, arranges multiple solid in the stage casing of prosthesis handle and distal end
Determine hole, fixing hole runs through prosthesis handle from the outside of prosthesis handle to inner side, and fixing hole is 2-5, lengthwise centers line and the vacation of fixing hole
The length direction of body handle is vertical, and the lengthwise centers line of multiple fixing holes is parallel to each other.
Artificial hip prosthesis' handle of above-mentioned treatment Periprosthetic fracture, the fixing hole be elongated hole, the length side of elongated hole
To the length direction along prosthesis handle, the length of the length direction of elongated hole more than Interal fixation screw diameter, elongated hole it is horizontal
Length match with the diameter of Interal fixation screw.
The invention has the beneficial effects as follows：
The present invention is reserved with fixing hole on original prosthesis handle, in Periprosthetic fracture after treating hip replacement,
Fixation can merely be adopted, it is not necessary to which wirerope cerclage is fixed.Interal fixation screw can pass through reserved fixing hole with
Inside and outside two-layer cortex is fastened around the fracture of femur, reaches good fixed effect, this relative to traditional prosthesis handle around
Screw can only be penetrated for the one layer of cortex of bone in outside after fracture, and its mechanical stability is greatly increased；And the long hole shape of fixing hole
Design does not produce stress shielding, and just with the fine setting of steel plate locus, Interal fixation screw is smoothly inserted.Present invention knot
Structure is simple, easy to use, it is adaptable to treatment when fracturing around prosthesis handle, makes the fixing-stable, firmly of fracture site, reaches
Rehabilitation and the functional rehabilitation of patient are advantageous to preferable surgical effect.
Description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the side view of Fig. 1；
Fig. 3 is the use state schematic diagram of the present invention.
Mark in figure as follows：Prosthesis handle 1, fixing hole 2, femur 3, steel plate 4, fixing screws 5.
Specific embodiment
The present invention is made up of prosthesis handle 1, fixing hole 2.
Show in figure, arrange multiple fixing holes 2 in the stage casing of prosthesis handle 1 and distal end, fixing hole 2 is outer lateral from prosthesis handle 1
Prosthesis handle 1 is run through in inner side, and the lengthwise centers line of fixing hole 2 is vertical with the length direction of prosthesis handle 1, the length of multiple fixing holes 2
Center line is parallel to each other.
In the treatment, Interal fixation screw 5 can be passed through around the fracture of the fixing hole 2 and femur 3 reserved on prosthesis handle 1
Inside and outside two-layer cortex is fastened, and reaches good fixed effect.
Show in figure, fixing hole 2 is 2-5, preferred amount is 3.The quantity of the fixing hole 2 of embodiments of the invention is
3.
Show in figure, fixing hole 2 is elongated hole, the length direction of elongated hole along prosthesis handle 1 length direction, the length of elongated hole
The length in direction is more than the diameter of Interal fixation screw 5, the horizontal length of elongated hole and the diameter phase of Interal fixation screw 5
Match somebody with somebody.Fixing hole 2 is not produce stress shielding using the advantage that long hole shape is designed, and just with the fine setting of the locus of steel plate 4, make
Interal fixation screw 5 is smoothly inserted.
