Abstract
An anterolatral distal tibial dissection bone fracture plate comprises a head portion and a batten under the head portion. The batten is provided with a twisting position, the head portion is a fan-shaped concave arc surface which is equipped with a triangular window, one side of the front edge of the fan-shaped concave arc surface is provided with a fork, the shape of the fork matches with that of a distal medial tibial, the fork is equipped with two internal ankle screw nail holes, the other side of the front edge of the fan-shaped concave arc surface is a Chaput tubercle fixing block matching with a lateral distal tibial, the Chaput tubercle fixing block is equipped with a Chaput tubercle screw nail hole, the remained portion of the front edge of the fan-shaped concave arc surface is a middle fixing block matching with a middle portion of an anterior distal tibial and a ventral condyle, and three screw nail holes are arranged on the middle fixing block. The anterolatral distal tibial dissection bone fracture plate can effectively cover the distal medial tibial, the lateral distal tibial, the middle portion of the anterior distal tibial and the ventral condyle, is simple in operation, and provides strong, effective and perfect internal fixation for distal tibial fracture particularly for Pilon fracture.
Description
(1) technical field
This utility model relates to a kind of distal tibial fracture blade plate.
(2) background technology
The big polyphyly high-energy damage of distal tibial fracture (Pilon fracture) of involving facies articularis inferior tibiae causes, treatment is very thorny clinically, disability rate is very high, the bone fracture internal fixation material of operative treatment has Herba Trifolii Pratentis steel plate, distal tibial dissection armor plate, distal tibial LCP and limited internal fixation to add exterior fixation bracket etc. at present, be on the increase on the Therapeutic Method, upgrade, but post-operative complication, disability rate are still very high.
The head of trifolium-shaped blade plate is trifolium-shaped, it below the head vertical bar plate, the general medial distal tibia of using, wipe out intermediary leaf plate and can be applicable to the front side, but the distal tibial outside is reversed with key connecting place, the following vertical bar plate of trifolium-shaped blade plate head can not be complementary with it, so can not use the distal tibial outside.The distal tibial dissection armor plate can be complementary with the distal tibial outside, but just can't satisfy the internal fixation requirement when preceding inboard of distal tibial and fracture of medial malleolus.Distal tibial LCP fixed range is very narrow, can only satisfy the needs of localized immobilization.Limited internal fixation adds exterior fixation bracket often needs over-articular to fix, and can not satisfy early functional exercise, can only use as the emergency treatment means.
The patent No. is that 200720111040.9 Chinese utility model patent discloses a kind of distal tibial outside blade plate, can effectively and outside before the distal tibial be complementary, satisfied fixing also can be provided, but the blade plate area is bigger, need peel off morely in the art, fracture blood fortune is destroyed serious relatively, and is bigger to the soft tissue influence, joint line and fracture end showed unclearly when postoperative was clapped the positive bit slice of X, and can not coat distal tibial effectively.
(3) summary of the invention
Existing distal tibial fracture blade plate blade plate area is big, joint line and fracture end showed unclear, as can not to coat distal tibial effectively deficiency when postoperative was clapped the positive bit slice of X in order to overcome, and we provide, and a kind of blade plate blade plate area is less, can know demonstration joint line and fracture end when postoperative is clapped the positive bit slice of X, can coat distal tibial, the simple distal tibial anterolateral anatomical bone plate of operation technique effectively.
The technical scheme in the invention for solving the technical problem is: outside anatomical form locking bone fracture plate before a kind of distal tibial, comprise the lath that head and head are following, described lath is provided with bone screw hole, have the place of reversing on the described lath, the place of reversing of described lath is complementary with the transition position torsional part of the preceding outside of distal tibial with the backbone; Described head is a fan-shaped cancave cambered surface, described fan-shaped cancave cambered surface is provided with a triangular windows, the place ahead of described triangular windows is fan-shaped cancave cambered surface leading edge, one side of described fan-shaped cancave cambered surface leading edge has a bifurcated, the shape of described bifurcated and medial distal tibia is complementary, and this branch is stuck and is provided with two internal malleolus screw holes; Another lateral margin of described fan-shaped cancave cambered surface leading edge is the Chaput tuberosity fixed block that is complementary with the distal tibial outside, offers a Chaput tuberosity screw hole on the described Chaput tuberosity fixed block; The remainder of described fan-shaped cancave cambered surface leading edge is the center fixed piece that is complementary with distal tibial front side mid portion and back ankle, offers three screw holes on the described center fixed piece.
During use this utility model is affixed on the tibia, bone screw is passed each screw hole get final product.
The beneficial effects of the utility model are: 1. the head of blade plate offers a triangular windows, make blade plate blade plate area less, destroy less relatively to fracture blood fortune, less to the soft tissue influence, and can know demonstration joint line and fracture end when postoperative is clapped the positive bit slice of X, can also effectively observe the answer situation of fracturing by this triangular windows.2. can cover medial distal tibia, the distal tibial outside, distal tibial front side mid portion and back ankle effectively, operation technique is simple, and to the distal tibial fracture, particularly the Pilon fracture provides strong, effective, ideal internal fixation.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a plane graph of the present utility model.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.
With reference to Fig. 1, Fig. 2, outside anatomical form locking bone fracture plate comprises head 1 and the head lath 2 below 1 before a kind of distal tibial, and described lath 2 is provided with 3 to 5 synthetism screw hole 3, can select to use as the case may be.Have on the described lath 2 to reverse and locate 4, the place of reversing of described lath 4 is complementary with the transition position torsional part of the preceding outside of distal tibial with the backbone.
Described head 1 is a fan-shaped cancave cambered surface, described fan-shaped cancave cambered surface is provided with a triangular windows 5, the place ahead of described triangular windows 5 is fan-shaped cancave cambered surface leading edge, one side of described fan-shaped cancave cambered surface leading edge has a bifurcated 6, described bifurcated 6 is complementary with the shape of medial distal tibia (being internal malleolus), this bifurcated 6 is provided with two internal malleolus screw holes 7, is used for fixing fracture of medial malleolus; Another lateral margin of described fan-shaped cancave cambered surface leading edge is the Chaput tuberosity fixed block that is complementary with the distal tibial outside (being the Chaput tuberosity), offer a Chaput tuberosity screw hole 8 on the described Chaput tuberosity fixed block, be used for fixing Chaput tuberosity place fracture; The remainder of described fan-shaped cancave cambered surface leading edge is the center fixed piece that is complementary with distal tibial front side mid portion (being the joint leading edge) and back ankle, offers three screw holes 9 on the described center fixed piece, is used for fixing joint leading edge and back ankle.
