Description
Technical field
The present invention relates to a kind of instruments resetted during surgery to fracture of calcaneus, belong to orthopedic medical device technology neck
Domain.
Background technology
Fracture of calcaneus is most common tarsal fracture, and 85%~90% is intra-articular fracture, is involved with rear facies articularis ossium more.
Fracture of calcaneus, which is mostly the violence of calcaneum axial direction, to be caused, and falling from high altitude, traffic accident etc. are common Risk Factors.More patients with fractures is tired
And the change at subtalar joint face, the out-of-flatness of articular surface and the angles Boiller and the angles Gissane can lead to the hair of traumatic arthritis
It is raw.The deformities of calcaneum can lead to a series of problem simultaneously, if tibial astragaloid joint is hit, collateral fibular ligament Impingement Syndrome,
It is lifted on heel weak etc..Because calcaneum and surrounding anatomical structures are complicated, local soft tissue covering quality is poor, therefore treats difficulty, and after
Something lost disease is more, and prognosis is poor.It performs the operation in calcaneus fractures, the purpose of operation is to restore width of calcaneus, calcaneum knot
Save joint angle and the calcaneum angle of the crossing, correction overturning deformity.Calcaneum open reduction is advocated first by Morestin, and method is
Through lateral incision outside calcaneum, levers up collapsed fracture block and resetted.Currently, this method has become treatment displacement fracture of calcaneus most
Common and effective method.Its advantage is that fracture can reach anatomical reduction, it can be securely fixed reseting fracture block, allow early stage work(
It can take exercise.But soft tissue stripping is extensive in party's magic arts, and damage is larger, and there are notching edge necrosis, infection, posterior articular surface fracture
The complication such as block necrosis are currently replaced by new closed reduction internal fixation method.
When using being fixed in closed reduction, since articular step-off, the width of calcaneum can usually occur after fracture of calcaneus
Become larger, while the high compression of calcaneum, need to be carried out at the same time in calcaneus fracture diaplasis it is orthopedic, therefore closed reduction need it is a variety of
Instrument is clamped from calcaneum both sides and bottom, needs more people's compounding practices, resetting time is long and is difficult to achieve the effect that satisfied.
So far, such case is not effectively improved, and is constrained the implementation of fracture of calcaneus closed reduction treatment and is carried out extensively,
There is an urgent need to be resolved.
Invention content
Technical problem to be solved by the invention is to provide a kind of fractures of calcaneus to combine restorer, and this joint restorer can
