Abstract
The utility model relates to an L-shaped posterior condylar tibial plateau steel plate which comprises an L-shaped main body, wherein the L-shaped main body comprises a vertical plate and a horizontal plate which are connected with each other, the junction of the vertical plate and the horizontal plate are arc-shaped, two vertical screw holes are formed on the vertical plate, three horizontal screw holes are formed on the horizontal plate, and fixing holes are arranged under the three screw holes on the horizontal plate. The L-shaped posterior condylar tibial plateau steel plate has the benefits that the design well conforms to the dissection of posterior condylar tibial plateau, and enables the steel plate to suit a bone surface well, three fixing holes can fix the steel plate temporarily, and at the same time, the posterior horn of meniscus can be stitched for fixation, which is favorable for in-situ fixation and healing of meniscus; and the problems are solved that by adopting a conventional steel plate, the meniscus can not be easy to fix on a plateau in a stitching manner, and the conventional steel plate can not be well matched with bones.
Description
Technical field
This utility model relates to condyle plate behind a kind of L type tibial plateau.
Background technology
Meniscus is two meniscate fibrous cartilagees, is positioned at the articular surface in the tibial plateau inboard and the outside.Its transverse section is triangular in shape, and is outer thick interior thin, is spill above slightly, so that match with condyle of femur, for what put down, joins with tibial plateau below.Such structure makes condyle of femur on tibial plateau, form a darker depression just, thereby the stability of spheric condyle of femur and tibial plateau is increased.Meniscal front and back end is respectively attached to the position of the non-articular surface of tibial plateau pars intermedia, at intercondyloid spine the place ahead and rear.This position can be called meniscal anterior angle and relief angle again.From meniscal shape and position, briefly, meniscal function promptly is stabilized knee, spreads the knee joint load forces, promotes intraarticular nutrition.Just because of the steady load effect that meniscus played, knee joint weight loading exercise and unlikely damage have all the year round just been guaranteed.When brute force is moved suddenly, be prone to cause meniscus injury, even tear.Close to bend and tibia fixedly the time when knee joint is in, distal part of femur can cause medial meniscus to be torn owing to the excessive suddenly medial rotation of external force, stretch; In like manner, distal part of femur outward turning suddenly during like this, stretch, lateral meniscus also can break.In the clinical position, when the knee joint wound, run into meniscus injury through regular meeting.Now, people have carried out many researchs to meniscal biomechanics function, more and more recognize meniscal biomechanics functional importance; Thinking should not be simply with the excision of damage meniscus; And should repair them, but present steel plate is difficult to the meniscus sutured to platform, and not enough with the matching of bone; Therefore this utility model provides condyle plate behind a kind of L type tibial plateau, solves the problem of above-mentioned existence.
The utility model content
The purpose of this utility model provides condyle plate behind a kind of L type tibial plateau, overcomes the deficiency of above-mentioned aspect in the existing product.
The purpose of this utility model is to realize through following technical scheme:
Condyle plate behind a kind of L type tibial plateau; Comprise L type main body; L type main body is made up of interconnective stringer board and transverse slat, and the junction of stringer board and transverse slat is an arc, and stringer board is provided with two screw holes of vertically arranging; Transverse slat is provided with three transversely arranged screw holes, respectively is provided with a fixing hole under three screw holes on the transverse slat.
The beneficial effect of this utility model is: design more meets the dissection of tibial plateau postartis; Make steel plate and surface of bone more docile; Three fixing holes can provide the temporary fixed of steel plate; Simultaneously can sutured meniscus relief angle, be beneficial to meniscal anchored in place healing, solved present steel plate be difficult to the meniscus sutured to platform and with the not enough problem of the matching of bone.
Description of drawings
According to accompanying drawing this utility model is done further explain below.
Fig. 1 is the structural representation of condyle plate behind the described a kind of L type tibial plateau of this utility model embodiment.
Among the figure:
1, L type main body; 2, stringer board; 3, transverse slat; 4, screw hole; 5, fixing hole.
The specific embodiment
As shown in Figure 1; Condyle plate behind the described a kind of L type tibial plateau of this utility model embodiment comprises L type main body 1, and L type main body 1 is made up of with transverse slat 3 interconnective stringer board 2; The junction of stringer board 2 and transverse slat 3 is an arc; Stringer board 2 is provided with two screw holes of vertically arranging 4, and transverse slat 3 is provided with three transversely arranged screw holes 4, respectively is provided with a fixing hole 5 under three screw holes 4 on the transverse slat 3.
Clinically,, need in the art to cut the observation that the meniscus relief angle is beneficial to articular surface, but present steel plate does not all have fixing hole 5, make the meniscus relief angle be difficult to sutured to platform in order to expose the tibial plateau posterior articular facet.Three fixing holes 5 of this utility model can provide the temporary fixed of steel plate, simultaneously can sutured meniscus relief angles, be beneficial to meniscal anchored in place healing.
