Description
Technical field
The utility model is related to metal abnormity dissection armor plate, and in particular to one kind aids in single-skin drum for intertrochanter fracture of femur
The oblique T-shaped metal deformed steel flats of matter internal fixation treatment.
Background technology
Intertrochanter fracture of femur is the common wound of Orthopedic Clinical.Treatment method is various.It is many to young, Fracture Simple patient
The femur of the method treatment displacement such as interior fixation is combined with hollow nail using Gamma nails, reconstruction nail, PFN, dynamic hip screw (DHS)
Intertrochanteric fracture, clinical efficacy is preferable.To old age, osteoporosis, comminuted fracture patient, due to femoral fracture near-end cancellous bone
Quality Down, the cripetura of postoperative loaded exercise neck of femur, bone nonunion, the interior fixed incidence that loosens are higher, affect the treatment.Recently adopt
With the intertrochanter fracture of femur of the various displacement of PFNA internal fixation treatments, more satisfied clinical efficacy is obtained, but still can not solve
The problems such as postoperative neck of femur cripetura, interior fixed loosening, femur neck screw incision hip joint.
The content of the invention
The purpose of this utility model is：A kind of intertrochanter fracture of femur mono cortex is designed to fix with tiltedly T-shaped metal abnormity
Dissection armor plate, the oblique T-shaped metal abnormity dissection armor plate combines internal fixation operation treatment osteoporotic with DHS, hollow nail, crushes
Property the various fracture such as femoral intertrochanteric A2,3 types, it is to avoid/reduce postoperative neck of femur cripetura, interior fixed loosen that to move back nail, small steel plate disconnected
Split, coxa vara, bed rest time long, Deep vain thrombosis, bone nonunion, femur neck screw incision hip joint etc. it is a series of it is postoperative simultaneously
Hair disease.
Technical solution of the present utility model is：The oblique T-shaped metal deformed steel flats includes transverse arm and trailing arm, and transverse arm is fixed
On the top of trailing arm, transverse arm is to the right rake angle 37o of trailing arm, or transverse arm is to the left rake angle 37o of trailing arm；Three screws are set on transverse arm
Hole, both sides screw hole is in 5o introversion angulations with middle screw nail, is the screw hole design of band silking；The middle part of trailing arm
Screw hole is not stayed, its afterbody is designed as multiple double list/locking and pressurizing screw holes, 3-4 groups/hole.
Wherein, transverse arm：A width of 2.5-3cm；Trailing arm：Length is 6-9cm, and thickness is 2.0mm, 2.5mm, 3.0mm, lock screw
Bore dia 3.5mm.
Wherein, the afterbody appropriateness pre-bending backward of trailing arm.
The utility model has advantages below：
1st, oblique T-shaped metal deformed steel flats is used in femoral bone tuberosity bone in DHS, the hollow nail combination same operative incision of fixation
Broken line is remote, near-end aids in being fixed in mono cortex bone, further increases fracture end stability, and realization is left the bed, bears a heavy burden early, effectively
Avoid/reduce neck of femur cripetura, move back nail, small Plate break, bone nonunion, femoral head incised injury etc., clinical effectiveness satisfaction is worth pushing away
Wide application；
2nd, transverse arm is to the right rake angle 37o of trailing arm, or transverse arm, to the left rake angle 37o of trailing arm, angle design is reasonable, operation side
Just；
3rd, the afterbody appropriateness pre-bending backward of trailing arm, is easy to be fitted with lateral side of femur cortex bone face；
4th, the thickness of trailing arm is 2.0mm, 2.5mm, 3.0mm, and lock screw bore dia 3.5mm, firmer, not easily broken plate is kept away
Exempt from disconnected plate risk.
5th, screw hole is not stayed in the middle part of trailing arm, and its afterbody is designed as multiple double lists/locking and pressurizing screw hole, 3-4
Group/hole, increases across fracture line place's intensity.

Specific embodiment
As Figure 1-4, the oblique T-shaped metal deformed steel flats includes transverse arm 1 and trailing arm 2, and transverse arm 1 is fixed on the top of trailing arm 2
End, transverse arm 1 is to the right rake angle 37o of trailing arm 2, or transverse arm 1 is to the left rake angle 37o of trailing arm 2；Three screw holes 3, both sides are set on transverse arm
Screw hole is in 5o introversion angulations with middle screw nail, is the screw hole design of band silking；Do not stay spiral shell in the middle part of trailing arm 2
Nail, its afterbody is designed as multiple double list/locking and pressurizing screw holes 4,3-4 groups/hole.
Wherein, transverse arm：A width of 2.5-3cm；Trailing arm：Length is 6-9cm, and thickness is 2.0mm, 2.5mm, 3.0mm, lock screw
Bore dia 3.5mm.
Wherein, the afterbody appropriateness pre-bending backward of trailing arm.
Surgical procedure of the present utility model is：Epidural cavity or combined spinal-epidural anesthesia are taken, patient takes dorsal position, Ipsilateral hip pad
Pillow, makes body coronal-plane about be in 15 ° with operating table；Thigh lateral longitudinal incision is taken downwards at the downward 5-6cm in femoral greater trochanter summit,
About 8 cm are long, cut that skin is subcutaneous and tensor fasciae late muscle, the partial cut musculus vastus lateralis at 5mm under femoral greater trochanter stop, far
Longitudinally slit sarolemma, muscle bundle are held, femur periosteum is peeled off forward to fracture, appear near, distal end of fracturing；According to steady after anatomical reduction
Fixed degree squeezes into 1-2 root Kirschner wire fixation fracture ends temporarily, to femur at femoral bone tuberosity backbone's intersection and downward 2.0-2.5cm
Neck 130o directions are horizontally driven into 2 diameter 2.5mm Kirschner wires；Conventional DHS, hollow nail resected femur intertrochanteric fracture are near, distal end
After safe, a small otch in longitudinal direction is taken in the nearly greater trochanter level in outer top before thigh, about 8mm is long, and vessel forceps point are near to femoral bone tuberosity
Folding end, at the cortex of bone of front, according to the corresponding tiltedly T-shaped special-shaped dissection armor plate of left and right selection it is slightly moulding after fit in femoral bone tuberosity it is near,
Remote folding end, long drill bit drills through bit guide, is screwed into mono-/bis-cortex fixing screws；Interim fixation Kel's needle is removed, is expanded under tuberosity
The bone mud that hole obtains is planted and fixes fracture in oblique T plates, closes art mouthful, puts piece drainage of silicone tube.
