Re: Проксимальный и дистальный переломы tibia

The subject of valgus malalignment of the distal fragment in distal tibial fractures is one which I was asked to look into for the SIGN bibliography. There are a number of studies suggesting that malalignment is less common if the fibula is fixed. The following is taken from the SIGN bibliography section on PubMed searches on the subject.
a.. Search String - "Tibial Fractures"[MeSH]AND "Fracture Fixation, Internal"[MeSH] AND "Fibula"[MeSH]

Fixation of the fibula can help to prevent valgus it other options are not used. If alignment is reached by distractor and maintained by locking screws it is not necessary to touch the fibula unless its displacement affects the ankle joint involving the lateral border of the mortise.
Maybe the problem is of special interest for SIGN nail users because both distal holes of the nail are oval not round so may cause lack of stability in frontal plane in very low fractures. As a solution one may insert two locking screws into one hole.

I assume the articles analyze mostly traditional nailing techniques, don't they?
There are some more tricks which allow not to plate the fibula and provide good alignment and stability. A small wire distractor can provide alignment and restore length of both tibia and
fibula. Angular stability of the tibia is provided by insertion of more than two conventional medial-lateral locking screws. To maintain the position of the fibula perQ insertion of a single position screw often could be enough. I bet the articles didn't analyze the options.
  
A typical case is attached, also an image with intra-op reduction obtained by a small wire distractor, in the moment of insertion a Poller wire in AP direction. Fixation by a SIGN nail. Despite the fibula was not fixed healing was obtained with the unchanged alignment.

Alex:
Very interesting application, but is the final position in a little distal varus with some fibula
distraction? Would that have been eliminated by fibula plating?

At least both the ankle mortise and tibial alignment look acceptable, don't they?
TDVC> Would that have been eliminated by fibula plating?
I am just trying to illustrate that prevention of 1)tibial valgus and 2)loss of reduction can be provided without fibular plating. Small changes of conventional nailing techniques allow to maintain reduction of the tibia reliably without adjunctive fibular stabilization.
In delayed cases acute length restoration performed only in the tibia may leave the fibula shortened thus change the mortise. So it is reasonable to restore length of both bones simultaneously by distractor and fix the fibula not with open reduction and plating but just by a single perQ screw. Example attached.

Alex, this is a fracture which can easily be managed in a cast.Why would you want to nail it?

Even in case of full recovery with a cast it occurs much later than after nailing. In a cast such a patient hardly ever would have been walking with weight-bearing to 3-4 weeks. In our unit cast is never used for the tibia fractures in adults.
Also the particular patient had unstable injury of the pelvis and open fracture of the humerus.
