Abstract
The invention relates to a minimal invasive combined pressurizing and locking bone fracture plate for trochanter comminuted fracture and femoral neck fracture. The bone fracture plate comprises a trochanter rear-side fixing plate and a femoral proximal-end fixing plate, which are connected into an integrated structure for respectively covering the trochanter rear side and femoral proximal end in an annular shape, wherein first locking holes are respectively formed on two ends of the trochanter rear-side fixing plate, and first locking nails which penetrate the rear side of the trochanter crown head end and the rear side of the trochanter crown bottom end are locked in the two first locking holes respectively; three second locking holes, arranged in a regular triangle way, are formed on the femoral proximal-end fixing plate, a second locking nail for locking femoral trochanter, femoral neck and bulb penetrates at least one second locking hole; and the trochanter rear-side fixing plate and the femoral proximal-end fixing plate are connected into an integrated structure for covering the trochanter rear side and femoral proximal end in an annular way. By utilizing a ball lag screw or a locking lag screw, tensioning of the trochanter, the femoral neck and the bulb and positioning lock on the femoral diaphysis are realized, so the minimal invasive combined pressurizing and locking bone fracture plate for the pulverous trochanter fracture and femoral neck fracture has the advantages of simpleness in operation, small cut, good fixing effect, firm tensioning, no potential safety hazards in long term use, no deformation and good treatment effect and is beneficial to accurate diaplasis.
Description
Technical field
The present invention relates to the orthopaedic medical treatment technical field, is a kind of Wicresoft tuberosity comminuted fracture and fracture of femoral neck connection type locking and pressurizing blade 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 structure; Easy to operate, otch is little, can effectively lock tuberosity comminuted fracture and fracture of femoral neck; Locking is firm, stable; Help proper reset, do not influence femoral bone cavitas medullaris and fracture regrowth, Wicresoft's tuberosity comminuted fracture that therapeutic effect is good and fracture of femoral neck connection type locking and pressurizing blade plate.
In order to achieve the above object; The technical scheme that the present invention adopts is: a kind of Wicresoft tuberosity comminuted fracture and fracture of femoral neck connection type locking and pressurizing blade plate; It is characterized in that comprising tuberosity rear side fixing head and near end of thighbone fixing head; Tuberosity rear side fixing head is the arc line type curved-surface structure that coincide with the tuberosity trailing flank, and the two ends of tuberosity rear side fixing head are respectively equipped with first lock hole, locks first locking nail that runs through tuberosity crown head end rear side and hat bottom rear side in two first lock holes respectively; The near end of thighbone fixing head is and the identical structure of near end of thighbone lateral surface, and the near end of thighbone fixing head is provided with three second lock holes that are triangular row portion, is penetrated with second locking nail that locks femoral bone tuberosity, neck of femur and bulb at least one second lock hole; Tuberosity rear side fixing head and near end of thighbone fixing head link into an integrated entity and are the structure of ring-like coating tuberosity rear side, near end of thighbone.
Be connected with key connecting plate on said tuberosity rear side fixing head or the near end of thighbone fixing head, key connecting plate is provided with the 3rd lock hole more than, and the 3rd lock hole lock runs through the 3rd key locking nail of femur.
The middle part of said tuberosity rear side fixing head is provided with first lock hole more than.
Said first lock hole is ball-type waist type groove, and first locking nail is spherical pulling force nail.
Said second lock hole is the thread lock hole, and second locking nail is spherical pulling force nail or locking pulling force nail.
Said the 3rd lock hole is ball-type waist type groove or locking and pressurizing hole, and the 3rd locking nail is spherical pulling force nail or locking pulling force nail.
Run through a spherical pulling force nail and two locking pulling force nails in said second lock hole respectively.
The locking of blade plate is divided into the locking of tuberosity rear direction, near end of thighbone locking and key locking.The locking of tuberosity rear direction: tuberosity rear side fixing head two ends ball-type waist type groove locks spherical pulling force nail, and spherical pulling force nail is realized the tension tuberosity in interior direction, adjustable angle, or tension tuberosity and neck of femur; Near end of thighbone locking: with a thread lock hole of ball shape pulling force nail cross-under near end of thighbone fixing head; Spherical pulling force nail is worn to the tuberosity bulb through neck of femur by the tuberosity outside; Produce pulling force and can regulate the fracture clearance distance, the other two thread lock holes of two lockings of reuse pulling force nail cross-under near end of thighbone fixing head, two locking pulling force nails are worn to the tuberosity bulb through neck of femur by the tuberosity outside; Play location, locking effect; The butt joint of tuberosity fracture is stable, difficult loosening, helps resetting accurately, and is indeformable; Key locking: use spherical pulling force nail or the key connecting plate of locking pulling force nail locking as required; Key connecting plate uses spherical pulling force nail to cooperate the locking of locking and pressurizing hole with the key anastomosis of femur; Misfitting the place uses locking nail to cooperate lock hole locking; Fixed, non-loosening, life-time service does not have potential safety hazard.
The tuberosity rear side fixing head of blade plate of the present invention, near end of thighbone fixing head, femur connecting plate fit like a glove with the key side of tuberosity trailing flank, near end of thighbone lateral surface, femur respectively, utilize spherical pulling force nail or locking pulling force nail realize the tension of tuberosity, neck of femur, bulb respectively and on the femur backbone positioning and locking, it is simple to operate; Otch is little, and overall fixed is effective, strains firm, non-loosening; Life-time service does not have potential safety hazard; Help resetting accurately, indeformable, therapeutic effect is good.
