Description
Technical field
This utility model relates to medical ancillary technique field, locking bone fracture plate outside especially a kind of distal tibial.
Background technology
Along with social economy's level, the developing rapidly of transportation, damage by high-energy the Pilon caused and fracture increasing.Pilon fractures for one of the most complicated intra-articular fracture type, incidence rate accounts for 7% of distal tibial fracture, 20%-25% merges open damage, and often subsiding with the pulverizing in various degree of articular surface and metaphysis and compression, is more challenging classification of fracture on current clinical treatment.Due to the position when injured residing for foot and the difference of violence direction and energy, result in complexity and the multiformity of Pilon fracture performance.
At present, the major fracture block of Pilon fracture concentrates on the front side of tibiofibula far-end complex, rear side, inner side and outer side, research shows, Pilon fracture on rear side of far-end due to due to skin soft tissue condition not good enough, cause it the most complicated, therefore, many doctors attempt placing blade plate outside distal tibial, but because the placement direction of blade plate and location comparison are close to distal tibial synthetism face, easily occur that screw is strayed into joint and causes various complication.Meanwhile, existing tibia far-end external bone plate also needs to carry out pre-bending, easily causes blade plate and surface of bone to fit bad, makes blade plate unbalance stress, easily cause local stress excessive, finally affects the rehabilitation of patient.
Utility model content
The technical problems to be solved in the utility model is: outside distal tibial, place blade plate in order to solving, but because the placement direction of blade plate and location comparison are close to distal tibial synthetism face, easily occurs that screw is strayed into joint and causes various complication, tibia far-end external bone plate also needs to carry out pre-bending, blade plate and surface of bone is easily caused to fit bad, make blade plate unbalance stress, easily cause local stress excessive, the final problem affecting the rehabilitation of patient, this utility model provides locking bone fracture plate outside a kind of distal tibial, the geometry of space form in blade plate and distal tibial contact outside face and distal tibial outer surface form are matched, good laminating can be carried out with surface of bone, avoid because blade plate and surface of bone are fitted bad, and the problem causing local stress excessive occurs, effectively increase its fixed effect, be conducive to the rehabilitation of patient, the direction of screw hole is: after being screwed into screw, screw can be made to avoid the articular surface of distal tibial, reduce the generation of complication, improve the success rate of operation.
This utility model solves the technical scheme that its technical problem adopts:
Locking bone fracture plate outside a kind of distal tibial, comprise: integrated head and body, geometry of space form and the distal tibial outer surface form in described blade plate and distal tibial contact outside face match, described head is provided with several for blade plate head being fixed on the screw hole outside distal tibial, described body is provided with several fixing holes, the direction of described screw hole is: after being screwed into screw, and screw can be made to avoid the articular surface of distal tibial.
In order to the blood circulation of the surface of bone ensureing distal tibial fracture place is smooth and easy, accelerate the healing of fracture, described blade plate head offers vent.
As preferably, described screw hole is arranged on around vent.
As preferably, the hole slot formula of described fixing hole is hole half formula, and a described hole half formula fixing hole is made up of pressurize hole and up big and down small conical bore of kidney ellipsoid.Adopt the fixing hole of hole half formula, can according to the demand in actual operation process, up-down adjustment squeezes into the position of the screw in fixing hole, when ensureing plate fixation, avoids some important tissue sites as far as possible.
As preferably, described blade plate is rustless steel blade plate, pure titanium bone plate or carbon steel blade plate.
The beneficial effects of the utility model are: locking bone fracture plate outside a kind of distal tibial that this utility model provides, the geometry of space form in blade plate and distal tibial contact outside face and distal tibial outer surface form are matched, good laminating can be carried out with surface of bone, avoid because blade plate and surface of bone are fitted bad, and the problem causing local stress excessive occurs, effectively increase its fixed effect, be conducive to the rehabilitation of patient; The direction of screw hole is: after being screwed into screw, screw can be made to avoid the articular surface of distal tibial, reduce the generation of complication, improve the success rate of operation; Blade plate head offers vent, can ensure that the blood circulation of the surface of bone at distal tibial fracture place is smooth and easy, accelerates the healing of fracture; Adopt the fixing hole of hole half formula, can according to the demand in actual operation process, up-down adjustment squeezes into the position of the screw in fixing hole, when ensureing plate fixation, avoids some important tissue sites as far as possible.
