Abstract
The invention relates to a minimally invasive femoral neck comminuted fracture back side pressurizing type fixation bone fracture plate, which is characterized in that the bone fracture plate is in an H-shaped curved surface structure anastomotic with the back side of the femoral neck, four pins of the H-shaped bone fracture plate are respectively provided with locking holes, the locking holes of the two front pins of the H-shaped bone fracture plate are connected with spherical nails penetrating through the femoral neck and the ball head in a penetrating way, and the locking holes of the two back fins of the H-shaped bone fracture plate are connected with spherical nails penetrating through the femoral neck and the tuberositas in a penetrating way. The spherical nails are used for being connected with the front fins and the back fins of the H-shaped bone fracture plate in a penetrating way and being connected into in a waist-shaped spherical groove arranged on the middle waist in a penetrating way, when the spherical nails are locked in the waist-shaped spherical groove, the direction and the angle are adjustable, the tensioning of the femoral neck and the ball head, the tensioning of the femoral neck and the tuberositas and the tensioning of broken bone in the femoral neck are respectively realized, the bone fracture plate only needs to be mounted at cutting openings at the back side of the femoral neck, the operation is simple, the cutting openings are small, the comminuted fracture part of the femoral neck is completely fixed, the tension is firm, the looseness does not exist, no potential safety hazard is caused after long time use, the accurate resetting is favorably realized, the deformation does not occur, and the treatment effect is good.
Description
Technical field
The present invention relates to the orthopaedic medical treatment technical field, is a kind of Wicresoft neck of femur comminuted fracture rear side pressing type fixation bone fracture plate specifically.
Background technology
Along with the aging of China's population and the loose trend that linearly rises of fracture of middle-aged and elderly people; Interrelated data shows; The domestic average life span has reached 73 years old, and person in middle and old age's activity reduces gradually, also is to cause one of reason that person in middle and old age's osteoporosis sickness rate increases gradually; The patient age that hip (refer between femoral bone tuberosity and the neck of femur) fracture of bibliographical information more than 90% arranged is all at over-65s, and wherein 3/4 is the women.Traditional treatment is main with dynamic coxa; Be DHS compressive sleeve gooseneck boom nail, though its therapeutic effect get the nod already, comparatively complicated when clinical installation; And it is too big to the skeleton damage; Neck of femur and bulb standing part are a pulling force nail, and relative stability is poor, and the phenomenon of clinical practice generation product fracture is more; Only produce pulling force after the pulling force nail is installed, will reach proper reset during art and have certain degree of difficulty, add that blade plate contacts very little with bone surface, it is incorrect to cause resetting, and fixing unstable, therapeutic effect is poor; The head skirt diameter of DHS sleeve gooseneck boom nail is 13mm; Length 25～30mm, punching is bigger between the skeleton tuberosity when mounted, installs back gooseneck boom nail sleeve and basically intertrochanteric pulp cavity is stopped up; Stoped the circulation of pulp cavity inner blood and bone marrow; Influenced fracture regrowth speed equally, prolonged healing time, it is painful to have increased sufferer.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, simple to operate, otch is little, and locking is stable, helps proper reset, does not influence femoral bone cavitas medullaris and fracture regrowth, Wicresoft's neck of femur comminuted fracture rear side pressing type fixation bone fracture plate that therapeutic effect is good.
In order to achieve the above object; The technical scheme that the present invention adopts is: a kind of Wicresoft neck of femur comminuted fracture rear side pressing type fixation bone fracture plate; Its technical characterstic is that blade plate is the H type curved-surface structure that coincide with the neck of femur trailing flank; Four feet of H type blade plate are equipped with lock hole, and the lock hole cross-under of H type blade plate two forward foot in a step has the sphere nail that runs through neck of femur, bulb, and the lock hole cross-under of H type blade plate two rear feet has the sphere nail that runs through neck of femur, tuberosity.
Further, the middle part of the side of said H type blade plate is provided with lock hole, and cross-under has the sphere nail that runs through neck of femur in the lock hole.
Again further, said lock hole is a waist type ball-type groove.
Adopt above technical scheme, the beneficial effect that the present invention reaches is: the H type curved-surface structure and the neck of femur trailing flank of blade plate fit like a glove, and utilize the cross-under of spherical nail in the forward and backward foot of H type blade plate and the waist type ball-type groove on the middle part of the side; Direction and adjustable angle realize the tension of broken bone in tension and the neck of femur of tension, neck of femur and tuberosity of neck of femur and bulb respectively in the time of in the spherical nail locking waist type ball-type groove, need only blade plate can be installed in the neck of femur posterior incisions, and be simple to operate; Otch is little, and is fixing comprehensively to neck of femur syntripsis place, strains firm, non-loosening; Life-time service does not have potential safety hazard; Help resetting accurately, indeformable, therapeutic effect is good.
Description of drawings
Fig. 1 is a mounting structure sketch map of the present invention.
Among the figure: bulb 1, neck of femur 2, tuberosity 3, H type blade plate 4, the forward foot in a step 41, the rear foot 42, the middle part of the side 43, waist type ball-type groove 5,51,52.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Shown in Figure 1; A kind of Wicresoft neck of femur comminuted fracture rear side pressing type fixation bone fracture plate; Blade plate is the H type curved-surface structure that coincide with the neck of femur trailing flank; Four feet of H type blade plate 4 and the middle part of the side are equipped with waist type ball-type groove, and waist type ball-type groove 5 cross-under of H type blade plate two forward foot in a step 41 have the sphere nail that runs through neck of femur 2, bulb 1, and waist type ball-type groove 51 cross-under of H type blade plate two rear feet 42 have the sphere nail that runs through neck of femur 2, tuberosity 3; Waist type ball-type groove 52 cross-under of the H type blade plate middle part of the side 43 have the sphere nail that runs through neck of femur 2.Direction and angle can be according to the adjustings of neck of femur comminuted fracture situation in the time of in the spherical nail locking waist type ball-type groove, satisfy the tension of broken bone in tension and the neck of femur of tension, neck of femur and tuberosity of neck of femur and bulb.
