Description
Technical field
The present invention is a kind of distal tibial fixing device, is a hone lamella, and it is used for being fixed on distal tibial in ankle fracture
The skeleton at place.
Background technology
Tibia (Tibia) is positioned at the position of human calf, and its far-end (Distal) is positioned at human body ankle.Distal tibial it
Traumatic fracture (Traumatic Fracture), can be divided into arthrosis fracture (Articular according to the position of its fracture
Fracture), epiphyseal fracture (Metaphyseal Fracture), shaft fracture (Diaphyseal Fracture).And fracture
Situation can be divided into simple fracture (Simple Fracture), wedge type fracture (Wedge Fracture), comminuted fracture
(Complex Fracture).Above-mentioned fracture situation, may be with the situation of bone fragments dislocation in addition to causing skeleton fragmentation.
At present for distal tibial fracture, external fixator (External Fixator) or hone lamella (Bone can be used
Plate) fixing device, is arranged at distal tibial fracture through surgical operation by this fixing device, will with nail (Screw)
External fixator is incorporated on tibia, or is fixed with nail after being fitted on tibia by hone lamella, only external fixator relatively bone
Plate has several shortcomings: (1) external fixator volume is relatively big, must be arranged at outside patient body-surface place, so will result in the postoperative of patient
Patient's trip movable property more unsightly and can be given birth to a definite limitation by outward appearance；(2) external fixator is only applicable to specific fracture situation；
(3) according to research (the Comparison of the effects of compression plates and of Lewallen et al.
External fixators on early bone-healing, c66J.Bone.Joint Surg.Am.1084,1984.),
With the tibia that external fixator is rear, the situation of its skeleton new life is poor, and has relatively multiple hole.Additionally, use hone lamella to contract
Short length of patient stay, patient can comparatively fast be replied normally, and reduces disunion (Nonunion) caused during bone fracture restoration
Or the most just heal (Malunion).
Bone plate designs the most in the streets, is to be as the criterion with standard skeleton model (Standard Bone Model) and produce.So
And on the implementation, between partly hone lamella can have because of its shape and actual application scenarios in time implanting, cause doctor before implantation hone lamella
To manually adjust the shape of hone lamella or need to find out and most preferably apply position.For the distal tibial hone lamella of vertical bar shaped, as the U.S. is special
The 8th, 328, No. 807 " System and methods for using polyaxial plates " of profit, if doctor in time implanting
When finding the suitableeest fixed range that fracture of tibia is located away from this hone lamella, it is necessary to be adjusted in operation in the way of artificial,
Make this hone lamella implant again after producing the deformation of expection, but such mode must lean on experience and the craft precision of doctor, even if
Doctor has experience and the craft precision of certain degree, also carries out because this adjustment need to expend certain time, and makes operating time prolong
Long, after being unfavorable for that patient is more on the contrary.Additionally, the distal tibial hone lamella of vertical bar shaped cannot effectively fix because of Pilon fracture and
The fracture fragments situation that Chaput fracture causes, if palpus fixing Pilon fracture or Chaput fracture, usual palpus uses more than two
Known hone lamella be fixed, unfavorable shortening operating time and simplify operating difficulty.
Separately, vertical bar shaped hone lamella in the streets, its nail locked, all in uniaxially, rather than relatively firm vertical the most biaxially, as
This is when with the fracture of known hone lamella fixed tibial far-end, and its fixing situation is poor.
Secondly, in time implanting hone lamella, hone lamella must be positioned most preferably to apply rear, position manually to be fixed with nail,
The most known tibia hone lamella does not discloses utilization with the shape of compatibility at distal tibial in chimeric mode, makes hone lamella when mounted
Distal tibial can be positioned directly in, the time being positioned manually with minimizing.3rd, the most known tibia hone lamella, is that nail is solid
Due to the screw of hone lamella, make the head of a nail (Cap) of nail be positioned on hone lamella, and the nail of nail is worn in tibia, but, tibia is remote
The human body weight of major part is born, if being only fixed on hone lamella one-tenth cantilever beam structure, its ankle joint with the head of a nail of nail at end
At Huo Dong, the strength of generation can make this nail body deform because of lever principle, the related anxiety making this hone lamella have dislocation or deform.
Therefore, the most still must a bone plate apparatus under the design of standard skeleton model, tibia end can be embedded in, and reduce
Nail problem on deformation after fixing, and make its bone plate apparatus can correspond to the fracture feelings of various distal tibials in one form
Shape.
