Along with the three who died and the more than 170 people injured in the bombings at the Boston Marathon, a lasting image of the episode may well be those who lost legs — a total of 14 people, including two patients who lost both legs.

In an event that celebrates runners with strong limbs, these victims will face a future without at least one of theirs.

Among the three patients remaining at Boston Children’s Hospital is a 10-year-old boy whose leg was amputated and remains in critical condition. He is suffering from multiple leg injuries, says spokeswoman Erin Tornatore. Other hospitals reporting patients who underwent amputations included Massachusetts General (4), Brigham and Women’s (1); Beth Israel Deaconess Medical Center (3); and Boston Medical Center (5).
