Abstract
The invention provides a steel plate placed behind the shin bone and used for fixing a shin bone far-end bone fracture. The steel plate placed behind the shin bone and used for fixing the shin bone far-end bone fracture comprises a long-strip-shaped steel plate body. The long-strip-shaped steel plate body comprises a near end and a far end. The far end is an expansion portion and the width of the far end is larger than those of the middle of the steel plate body and the near end of the steel plate body; the near end of the steel plate body and the far end of the steel plate body are respectively provided with an arc end; the inner side face of the steel plate body is recessed inwards and the far-end expansion portion of the steel plate body is bent outwards, so that the inward-recessed inner side face of the steel plate body and the far-end expansion portion bent outwards are matched with the appearance of the bone behind the far end of the shin bone; threaded holes are formed in the far end of the steel plate body, the far-end expansion portion and the middle portion of the steel plate body respectively. The far-end expansion portion of the steel plate body is further provided with two Kirschner wire fixing holes. Further, the bent angle of the far-end expansion portion is 4 degrees to 15 degrees. After the steel plate is placed to the portion behind the shin bone and used for fixing the shin bone fracture, recovery of the front soft tissues after an operation is facilitated, screws are used for locking, and the biomechanics requirement for firm fixation can be satisfied.
Description
Technical field
The medical apparatus and instruments that the present invention relates to a kind of fixing fracture of performing the operation, specifically for the interior fixed tibial fracture of distal of performing the operation, is placed in the steel plate at distal tibial rear.
Background technology
Distal tibial fracture refers to the fracture at 1/3 position under tibia, the normal fracture of fibula that merges, common clinically, distal tibial fracture comprises the fracture that does not relate to ankle joint and the fracture that relates to ankle joint (Pilon fracture), and Shinbone Pilon bone fracture accounts for 1% ~ 10% of fracture of the lower limb.In tibia and ankle joint fracture, account for 4% ~ 7%, along with the development of transportation and industrial or agricultural, high-energy damages and to cause this position fracture to have the trend of increasing, and traumatic condition is more complicated, complication is many, and disability rate is high, is one of the most refractory fracture.
Distal tibial fracture injury characteristic is clinically at present: 1) High energy trauma is common, often causes complicated fracture, and before shin, soft tissue injury is serious, and open fracture is common.2) damage is many from the place ahead, and before shin, soft tissue is weaker, thereby causes the front soft tissue injury of shin, opening more.
Existing fixation steel plate is to be all placed in the front inner side of tibia or front outside, easily because of tibia the place ahead soft tissue injury, necrosis, causes the serious complication such as plate exposure.Exterior fixation bracket increases hole for nailing nursery work and makes troubles to patient, at trans-articular, also can cause the stiff of ankle joint fixedly time.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of steel plate that is placed in tibia rear fixed tibial fracture of distal, the distal tibial fracture that is applicable to shank the place ahead soft tissue injury, can avoid the soft tissue of the place ahead damage and not affect ankle joint, avoids the generation of above complication.The technical solution used in the present invention is:
Be placed in a steel plate for tibia rear fixed tibial fracture of distal, comprise the steel plate body of a strip, described steel plate body has a near-end and a far-end; Far-end is enlarged portion, and width is greater than middle part and the near-end of steel plate body; The near-end of steel plate body and far-end all have the termination of arc;
The medial surface indent of steel plate body, the distal dilation portion of steel plate body is crooked laterally, and the medial surface of steel plate body indent and the distal dilation portion of bending laterally and the bone profile at distal tibial rear are matched;
Near-end, distal dilation portion and middle part at steel plate body are equipped with screw hole.
Further, the distal dilation portion at steel plate body is also provided with two Kirschner wire fixing holes.
Further, the angle of distal dilation portion bending is 4～15 degree.
Further, described near-end width is 16mm, and distal dilation portion width is 22mm, and the thickness of steel plate body is 2mm.
Further, the diameter of described screw hole is 5mm, and spacing is 20mm.
Further, the diameter of described Kirschner wire fixing hole is 2mm.
Advantage of the present invention: external biological mechanics and clinical practice result show, are placed in the steel plate at tibia rear, do not disturb the injured soft tissue in the place ahead, increase the safety of operation; Can reach the strong fixing biomechanics requirement of fracture.
Accompanying drawing explanation
Fig. 1 is that structure of the present invention forms schematic diagram (lateral surface visual angle).
The specific embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
The present invention, according to the Morphological Characteristics design steel plate shape at tibia rear, requires to design screw hole on steel plate according to the biomechanics of fracture fixation.
As shown in Figure 1: a kind of steel plate that is placed in tibia rear fixed tibial fracture of distal, comprise the steel plate body 1 of a strip, described steel plate body 1 has a near-end and a far-end; Far-end is enlarged portion, and width is greater than middle part and the near-end of steel plate body 1; The near-end of steel plate body 1 and far-end all have the termination of arc.Near-end width is 16mm, and distal dilation portion width is 22mm, and the thickness of steel plate body 1 is 2mm.It should be noted that, distal tibial refers to the bottom of tibia.
The medial surface indent of steel plate body 1, the distal dilation portion of steel plate body 1 is crooked laterally, and crooked angle is preferably 4～15 degree; The medial surface of steel plate body 1 indent and the distal dilation portion of bending laterally and the bone profile at distal tibial rear are matched.
Near-end, distal dilation portion and middle part at steel plate body 1 are equipped with screw hole 2.The diameter of screw hole 2 is 5mm, and spacing is 20mm.Screw hole 2 is positioned on the longitudinal axis of steel plate body 1.In the distal dilation portion of steel plate body 1, be provided with five holes, wherein three is screw hole 2; Two other is the Kirschner wire fixing hole 3 of diameter 2mm, for temporary fixed steel plate and sclerite, after waiting screw fixing, then pulls out Kirschner wire.
Clinical practice proves, the steel plate of above-mentioned shape is inserted after the fixed tibial fracture of tibia rear, is conducive to the recovery of postoperative the place ahead soft tissue, takes screw locking, can arrive strong fixing biomechanics requirement.
