Abstract
The utility model relates to a bone plate for tibial plateau posterolateral fracture. The bone plate comprises an L-shaped stainless steel sheet composed of a transverse portion and a vertical portion; the transverse portion is provided with three rows of holes; the first row of holes includes suture holes in the top end, which are inclined holes penetrating the front and top faces; the second row of holes includes small screw holes or Kirschner wire holes arranged below spaces of the suture holes; the third row of holes includes locking holes arranged below the small screws or Kirschner wire holes; the vertical portion is evenly provided with N pressure screw holes and a small screw hole or Kirschner wire hole in the length-wise direction; the inner surface of the bone plate is in a bent shape fitting the posterolateral shape of the tibia. The bone plate has the advantages that effective supporting is provided for posterolateral tibial plateau which suffers post-fracture displacement and collapse, postoperative meniscus repair is facilitated, and the bone plate can be well fitted to bone surfaces.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments that is used for the treatment of fracture, especially a kind of blade plate for outside fracture after tibial plateau.
Background technology
Tibial plateau is kneed important load structure, once fracture, makes inside and outside platform unbalance stress, will produce osteoarthrosis structural change.In the time that fracture compound comminuted occurs in outside after tibial plateau, usually merging serious soft tissue injury, is especially comparatively common with meniscal damage.Existing to the blade plate of fracture of the tibial plateau normally only for tibial plateau is slightly fractured, and Outboard Sections collapsed fracture and blade plate that postoperative meniscal reparation is integrated after the tibial plateau of simultaneously not holding concurrently.Conventionally the consequence that blade plate used is prone to is: though outside Platform Fracture heals after postoperative tibia, repaired preferably patient cannot be returned to one's perfect health for a long time because of meniscus, affect getting up early and take exercise and other daily life.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of blade plate that is more suitable for outside fracture after tibial plateau is provided.
The technical scheme in the invention for solving the technical problem is: a kind of blade plate for outside fracture after tibial plateau comprises the L shaped stainless sheet steel being made up of transverse part and longitudinal part.
In order finely to realize, blade plate and tibia are posterolateral to be fixed and facilitates postoperative meniscal reparation, and described transverse part is provided with three rounds, and the first round is suture hole, is located at top ends, for the inclined hole through positive and end face, for making fixing meniscus; Second row is Screw hole or Kirschner wire hole, is located at two below places between suture hole, for outside after fixing hone lamella and tibia; The 3rd arranges the below that is located at Screw hole or Kirschner wire hole for lock hole.
On described longitudinal part, be evenly provided with along its length N forcing screw hole and 1 Screw hole or Kirschner wire hole; For supporting the position that subsides of tibia, reach stability and fix.
In order to make the blade plate can be preferably and surface of bone laminating, its inner surface be with tibia after the identical curved shape of outside profile.
Ensureing under the prerequisite of steadiness, for reducing the contact area of blade plate and surface of bone, reduce blade plate bone fortune is caused to unnecessary destruction, described L-type stainless sheet steel periphery is designed to concavo-convex arc-shaped edges.
The beneficial effects of the utility model are to be: L-type blade plate of the present utility model is specifically designed to after tibia and when outside caves in, makes the impaired fracture compound comminuted situation of meniscus.1, this blade plate is provided with suture hole, and can be rear outside Platform Fracture retrodisplacement and subsiding provides effective supporting role, facilitates postoperative meniscal reparation simultaneously; 2, this blade plate can be fitted with surface of bone preferably, and the shape of its inner surface is consistent with key profile, and longitudinal part is provided with locating hole, is provided with its Kirschner wire hole simultaneously, and fixing stability in increasing, is conducive to the postoperative functional exercise of carrying out in early days; 3, the design of the concavo-convex arc-shaped edges of hone lamella periphery has reduced the contact area of blade plate and surface of bone, reduces bone fortune is caused to unnecessary destruction, is more conducive to shorten healing cycle.
Brief description of the drawings
Fig. 1 is main TV structure schematic diagram of the present utility model;
Side-looking structural representation when Fig. 2 is this utility model using state.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail:
As shown in Figure 1 and Figure 2, a kind of blade plate for outside fracture after tibial plateau comprises the L shaped stainless sheet steel 1 being made up of transverse part 11 and longitudinal part 12; Its transverse part 11 is provided with three rounds, and first row is suture hole 111, is located at top ends, and second row is Screw hole or Kirschner wire hole 112, is located at the below place between suture hole between two, and the 3rd row is lock hole 113, is located at the below in Screw hole or Kirschner wire hole.
On its longitudinal part 12, be evenly provided with along its length Screw hole, 121 and 1, N forcing screw hole or Kirschner wire hole 122.
Described stainless sheet steel 1 be with tibia after the identical curved shape of outside profile.In use, stainless sheet steel 1 is fitted on key 2 outer surfaces, makes like this stainless sheet steel be evenly distributed on surface of bone the extruding force of surface of bone, can not produce concentrative powerful extruding, reduce the stimulation to osseous tissue simultaneously.
Ensureing, under the prerequisite of steadiness, to reduce the contact area of blade plate and surface of bone, reduce bone fortune is caused to unnecessary destruction, described stainless sheet steel 1 periphery is designed to concavo-convex arc-shaped edges 13.
Claims (3)
1. the blade plate for outside fracture after tibial plateau, the L shaped stainless sheet steel 1 being made up of transverse part 11 and longitudinal part 12, is characterized in that: described transverse part 11 is provided with three rounds, and first row is suture hole 111, being located at top ends, is the inclined hole through positive and end face; Second row is Screw hole or Kirschner wire hole 112, is located at the below place between suture hole between two; The 3rd row is lock hole 113, is located at the below in Screw hole or Kirschner wire hole;
On described longitudinal part 12, be evenly provided with along its length Screw hole, 121 and 1, N forcing screw hole or Kirschner wire hole 122.
