Bike accident.

Airports are going to be a bitch for a while!

How are those pins supposed to help? One would imagine that they fix up all that shit before pushing pins in and checking movement.

[Azimuth]

That's gonna get infected.

nasty wound

[meowder]

A chunk of bone is gone, this might not end well.

Just lob it off.. not going to heal.

[Brandjuh]

Normally the pins (all around the leg) would hold the bones in a fixed position so they can heal.

I do not know why they choice this method because there is to less flesh to recover the wound, so far you can speak about a wound. Just amputate the leg.

This is an advanced procedure for the 'third world'. Think of it as two separate injuries, the broken bone and the soft tissue injury. This type of broken bone, if still covered with flesh, is easily treated. The pins are holding the leg in it's correct position until the bone, possibly with grafts, has the chance to grow back together.
The flesh injury, even with the missing tissue, is fairly easy to fix. The leg wound will be closed up with skin grafts. Think of a shark bite injury where a chunk of flesh is taken out. It won't look pretty once healed but is still certainly a viable limb as long as there is blood flow to the lower part of the leg, and nerve connections. You can see in the video that he is moving his toes for the doctor. They are checking that the limb is still viable and has not 'died', which then, at that point, would call for an amputation.

I' not an expert at this, but if you ask me that bone looks dead - hollow, dried out an dead. The flesh does not look like it war traumatically removed, more like it recessed and scared following a infectious process.
I guess the accident was treated with application fixateur externe, due to poor hygenic conditions the flesh around the punctures got infected. Those fixateure-punctures have to be held impeccably clean, else (as can be seen here) they become a highway for bacteria, leading directly to the none marrow, via skin, flesh and periostium. By the swelling of the foot and the pale nails I would say, that the blood circulation is almost cut off, resulting in the tissue fluid accumulation below the trauma.
