Bone punctured the femoral artery. how would surgeons fix this?

Surgery : If the patient hasn't bled to death there would be an arterial repair and whatever was appropriate for the bone.

Depends: Depends on the extent of the injury, either primary repair or with a graft or stented graft.

Vein or graft: We would directly repair this with a piece of vein or goretex, but for a bone to puncture the femoral artery is a horrific injury, and managing the vascular injury would have to be done in the context of how the patient is doing.
