Front screw locking holes are formed in the front side arm, rear screw locking holes are formed in the rear side arm, and edge concave parts are formed in the edge of the main plate body, the edge of the front side arm and the edge of the rear side arm; the thickness of the front side arm and the thickness of the rear side arm are smaller than the thickness of the main plate body; front kirschner wire fixing holes are further formed in the front side arm and formed along the edge of the front side arm, and rear kirschner wire fixing holes are further formed in the rear side arm and formed along the edge of the rear side arm.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of femoral-posterior condyles lockplate.
Background technology
The femoral-posterior condyles fracture is the femur condyle coronal shear fractures, claims again the hoffa fracture, is a kind of fracture of comparatively complicated type, often merges femoral intercondylar, supracondylar fracture, comprises complicated many plane joints facial bone folding and the condyle coronal shear fractures of varying level.Due to the particularity of above fracture, cause, when this type of fracture of diagnosis, very easily failing to pinpoint a disease in diagnosis, and interior fixedly difficulty.There is not yet at present the fixedly steel plate special of hoffa fracture both at home and abroad, the method of this type of fracture of traditional treatment is: comprise in skeletal traction through tibial tubercle, open reduction hollow nail, spongiosa nail etc. fixing, the problems such as difficulty, interior fixing not firm, interior fixedly difficulty but existence fracture and articular surface reset, the fracture redisplacement incidence rate is high, the incidence rate of the major complications such as the fracture delayed union caused thus, bone does not connect, malunion, ankylosis, traumatic arthritis is high, it is poor that knee joint function recovers, and easily leaves over deformity.
Summary of the invention
The purpose of this utility model is to provide a kind of femoral-posterior condyles fracture stabilization that can make and resets and strong interior fixing femoral-posterior condyles lockplate.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of femoral-posterior condyles lockplate, comprise the mainboard body, have main screw lock hole on the mainboard body, it is characterized in that: mainboard body far-end is connected with front side arm and posterolateral arm, mainboard body, front side arm and posterolateral arm are combined formation " Y " word camber structure, the length of posterolateral arm be less than the mainboard body length, be greater than the length of front side arm, mainboard body, front side arm and posterolateral arm are structure as a whole, front side arm outer end and the Jun Xiang the same side bending of posterolateral arm outer end; Have front screw lock hole on front side arm, have rear screw lock hole on posterolateral arm, mainboard body edge, front side arm edge and posterolateral arm edge all have marginal trough; The thickness of front side arm and posterolateral arm is less than the thickness of mainboard body.
According to described femoral-posterior condyles lockplate, it is characterized in that: also have front Kirschner wire fixing hole on described front side arm, front Kirschner wire fixing hole arranges along front side arm edge; Also have rear Kirschner wire fixing hole on described posterolateral arm, rear Kirschner wire fixing hole arranges along the posterolateral arm edge.
According to described femoral-posterior condyles lockplate, it is characterized in that: described main screw lock hole, described front screw lock hole and described rear screw lock hole are all with female thread, and lock screw all has been threaded in main screw lock hole, front screw lock hole and rear screw lock hole.
Overall structure in this utility model meets femur condyle dissects, and mainboard body edge, posterolateral arm edge and front side arm edge all have marginal trough, and flexible distortion, have plasticity, can be attached on femur condyle preferably.Can be according to this lockplate of the moulding attaching of classification of fracture, tighten after the lock screw of fixing use fixing different types femoral-posterior condyles fracture preferably.Lock screw is fixed rear by the screw lock hole and lockplate is into a single integrated structure, can play the effect of inner fixed support, and fixing strong firm, without outer fixing, can carry out early functional exercise, can make the femoral-posterior condyles fracture stabilization reset, and joint function recovery is good.
