The specific embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
As shown in Figure 1, the lateral condyle dissection armor plate comprises head zone A behind the tibial plateau of the present invention, neck area B and body zone C, head zone A is with flank region D, specifically comprise the first screw hole 1, the second screw hole 2, the 3rd screw hole 3, the 4th screw hole 4, the 5th screw hole 5, the 6th screw hole 6, overlapping hole 7, the first meniscus sewing hole 8, the second meniscus sewing hole 9, the 3rd meniscus sewing hole 10, plate body 11, the first screw hole 1, the second screw hole 2, the 3rd screw hole 3, the 4th screw hole 4, the 5th screw hole 5, the 6th screw hole 6, overlapping hole 7, the first meniscus sewing hole 8, the second meniscus sewing hole 9, the 3rd meniscus sewing hole 10 all is positioned on the plate body 11, being shaped as of plate body 11 is L shaped, the diameter of the first screw hole 1, the diameter of the second screw hole 2, the diameter of the 3rd screw hole 3, the diameter of the 4th screw hole 4, the diameter of the 5th screw hole 5 all is 3.5mm, the diameter of the 6th screw hole 6 is 4.5mm, the diameter of the first meniscus sewing hole 8, the diameter of the second meniscus sewing hole 9, the diameter of the 3rd meniscus sewing hole 10 all is 1mm.The first meniscus sewing hole 8, the second meniscus sewing hole 9, the 3rd meniscus sewing hole 10 is positioned at the first screw hole 1, the second screw hole 2, the 3rd screw hole 3, the 4th screw hole 4, the top of the 5th screw hole 5, the quantity of the 6th screw hole 6 is four and is positioned at the first screw hole 1, the second screw hole 2, the 3rd screw hole 3, the 4th screw hole 4, the below of the 5th screw hole 5, the quantity in overlapping hole 7 is four, and (quantity is not limited to present embodiment, can be one to five) and be positioned at the below of the 6th screw hole 6, the hole is overlapping forms by locking nail hole and the pressurization of sliding in overlapping hole 7, overlapping hole 7 be shaped as Pear-Shaped.
The first screw hole 1, the second screw hole 2, the 3rd screw hole 3, the 4th screw hole 4, the 5th screw hole 5, the first meniscus sewing hole 8, the second meniscus sewing hole 9, the 3rd meniscus sewing hole 10 are positioned at head zone A, and the first screw hole 1 and the first meniscus sewing hole 8 also are positioned at flank region D simultaneously.Head zone A dissects design for enclosing the joint, and there are three meniscus sewing holes (the first meniscus sewing hole, the second meniscus sewing hole, the 3rd meniscus sewing hole) on the top of head zone A.Flank region D strides across capitulum fibulae 20 upper limbs and supports lateral condyle behind the tibial plateau, and the width of flank region D is 0.8 cm to 1.0cm, and length is 1.0 cm to 1.2cm; The 6th screw hole 6 that two rows are arranged in parallel is positioned at neck area B, and overlapping hole 7 is positioned at body zone C.The back rake angle E that five degree are arranged between the horizontal direction of the horizontal direction of head zone A and body zone C.
Steel plate head and cervical region are the lock hole design, steel plate need not by force moulding cause docile, it is dissected radian and has satisfied most patients, as shown in Figure 2, the all lateral condyle direction designs behind the tibial plateau of the first head screws 21, the second head screws 22, the 3rd head screws 23, and the first head screws 21, the second head screws 22, the 3rd head screws 23 are in the side to intersect arranges, and avoids screw mutually to cut collision.Rear lateral condyle fractured strengthened supporting role, four-head section screw 24, the 5th head screws 25 vertical steel plates to the inside platform are squeezed into, and being combined inboard Platform Fracture can become to intersect enhanced stability with inboard platform hold-down screw is capable.The diameter of the first head screws 21 to the 5th head screws 25 is 3.5mm, and length is 30 to 180mm.The first head screws 21, the second head screws 22, the 3rd head screws 23, four-head section screw 24, the 5th head screws 25 are passed respectively the first screw hole 1, the second screw hole 2, the 3rd screw hole 3, the 4th screw hole 4, the 5th screw hole 5.The first meniscus sewing hole, the second meniscus sewing hole, the 3rd meniscus sewing hole are conducive to postoperative suture in situ meniscus, effectively keep meniscus.The screw that the 6th screw hole 6 is used is that diameter is the lock screw of 4.5mm, is parallel two rows and arranges, and provides larger screw fixedly to control strength, is conducive to the firm of blade plate.Being pressurizeed by locking nail hole and slip in overlapping hole 7, the hole is overlapping to be formed, and alternative os integumentale screw and the lock screw used fixed, and when using os integumentale screw, can produce the axial pressure effect to fracture end.Overlapping hole count can according to tibia epimere fracture, have one to five hole selective.
For lateral condyle dissection armor plate behind the tibial plateau of the present invention, specialized designs approaches on the capitulum fibulae, the concrete steps of this approaches are as follows: be close to the lateral collateral ligament leading edge and cut skin to deep fascia, the otch hypomere is peeled off along surface of bone and is adhered to tibialis anterior group stop, until facies articularis capitis fibulae, 60 degree of going down on one's knees, continuation is peeled off to rear side along the facies articularis capitis fibulae upper limb, lateral collateral ligament and popliteal tendon are retracted to rear side, slightly in medial rotation turn over tibia, can appear lateral condyle behind the tibial plateau.This approaches is simple and safe, need not to dissect nervus vasculairs, and without blood vessel Nerve tendon damage possibility, without impact, outside platform appears complete in the art, is conducive to the reduction of the fracture and fixes on stability of joint.Lateral condyle steel plate behind the tibial plateau of the dissection of inserting from front to back of this approach need configure dedicated.
The advantage of lateral condyle dissection armor plate is as follows behind the tibial plateau of the present invention: can be after approach appears tibial plateau on the capitulum fibulae lateral condyle fracture end, by inserting lateral condyle dissection armor plate behind the tibial plateau of the present invention behind the forward direction, place simple, operative approach safety, go out insufficiency of blood, take and lack, without blood vessel nerve injury risk; Steel plate of the present invention is dissected design and be need not moulding bending; Head zone is for enclosing the arthrodesis part, and the body zone is the tibia standing part, and in the processing platform fracture simultaneously, it is fixing to have taken into account resetting of fracture of tibia; The steel plate flank is rear lateral condyle support section, can be to the rear lateral condyle that subsides effective supporting role of having fractured after the placement; Three meniscus sewing holes are conducive to postoperative suture in situ meniscus, and the present invention is applicable to outer condylar fracture behind the tibial plateau, outside Platform Fracture, upper section of tibia fracture or above-mentioned merging fracture between arbitrarily.The lateral condyle dissection armor plate is easy for installation behind the tibial plateau of the present invention, and is fixed, can realize that Rapid reset fixes, safe and effective.After union of fracture, safe ready can steel plate be taken out through this approach.
Those skilled in the art can carry out various remodeling and change to the present invention.Therefore, the present invention has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
