The distal tibial fixing headTechnical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of distal tibial fixing head.
Background technology
The distal tibial fracture is clinical multiple injury, the most normal betiding pounded pressure, the violence of traffic accident all standing under high falling, the mine, tibial axis is to the main cause that violence is the distal tibial articular surface fracture of reversing of violence or lower limb, and two kinds of different damage mechanism cause the distal tibial fracture.The axial force that causes distal tibial fracture is the high-energy violence, cause articular surface cave in, broken apart, the metaphysis sclerotin is pulverized, soft tissue injury, major part has fracture of fibula simultaneously, prognosis is not good.The position of ankle joint and classification of fracture are closely related when injured, and the sole of the foot is that tibia rear sclerite is bigger when bending; In the time of neutral, it is " Y " type fracture of big free bone piece that the vertical axial violence makes whole damage of articular surface or forward and backward ankle; The roomy front portion of astragalus just entered in the ankle cave when back of the body was stretched, made tibia front portion and fracture of tibia; When turning up, reverse violence and can make distal tibial outside fracture; In when turning over, inboard fracture can appear; When axial violence with reverse the violence synergy, ankle joint can be dislocated, the articular surface intercalation, and simultaneously, with the metaphysis comminuted fracture, it is extremely unstable that the joint becomes.Traditional method is treated this type of fracture and comprised: closed reduction, external plaster fixation, calcaneal traction, exterior fixation bracket are fixed, open reduction steel plate internal fixation, but there is the articular surface malreduction, fix problems such as not firm, major complications incidence rate height such as the wound easy infection that causes thus, fracture delayed union, bone does not connect, malunion, ankylosis, traumatic arthritis, chronic osteomyelitis, it is poor that ankle joint function is recovered, and easily leaves over deformity.
Summary of the invention
The purpose of this utility model provides and a kind ofly the distal tibial fracture stabilization resetted and the distal tibial fixing head of strong internal fixation.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of distal tibial fixing head comprises plate body, has screw fixed hole on the plate body, it is characterized in that: the plate body upper end is connected with right arm and left side arm, and right arm, left side arm and plate body are combined formation " T " font structure; Have right fixing hole on the right arm, have left fixing hole on the arm of left side; Right arm edge and arm edge, left side all have the side arm depression; The plate body upper end-face edge has the Kirschner wire fixing hole; Right arm, left side arm and plate body are structure as a whole.
Dissect because plate body of the present utility model meets distal tibial, right arm edge and arm edge, left side all have the side arm depression, have plasticity, and flexible distortion can be pasted preferably and be lied prostrate on tibia internal malleolus and Jower tibiofibular joint.According to this fixing head of the moulding attaching of classification of fracture, tighten behind the hold-down screw fixing different types distal tibial fracture preferably, be specially adapted to auspicious Di Shi III type distal tibial fracture.Can play the effect of inner fixed support after the locking screw is fixing, strong fixing, need not external fixation, but early functional exercise, joint function recovery is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is further described:
A kind of distal tibial fixing head as shown in Figure 1, comprises plate body 1, has screw fixed hole 2 on the plate body 1, and plate body 1 upper end is connected with right arm 3 and left side arm 7, and right arm 3, left side arm 7 and plate body 1 are combined formation " T " font structure; Have right fixing hole 4 on the right arm 3, have left fixing hole 6 on the left side arm 7; Right arm 3 edges and left side arm 7 edges all have side arm depression 8; Plate body 1 upper end-face edge has Kirschner wire fixing hole 5; Right arm 3, left side arm 7 and plate body 1 are structure as a whole.
Have right fixing hole on the right arm of the present utility model, have left fixing hole on the arm of left side, be used for fixing fracture of medial malleolus and lower tibiofibula and separate.Right arm edge and arm edge, left side all have a plurality of side arms depression, have plasticity, and flexible distortion is beneficial to mouldingly, can paste preferably and lie prostrate on tibia internal malleolus and Jower tibiofibular joint.The plate body upper end-face edge has the Kirschner wire fixing hole, is beneficial to Kirschner wire fixed tibial articular surface fracture.
Making material of the present utility model is a titanium alloy, and histocompatibility is good, firm light, fatigue resistance good.The thickness of plate body upper end and right arm, left side arm is thinner than other position, meets the topography structure.
This utility model subsides are lied prostrate in distal tibial, and behind the nail that tightens the screw, the distal tibial fracture is multi-faceted firm fixed, and it is fixing that the distal tibial fracture stabilization is resetted.
