Ball bearings, nails removed from marathon bombing patients

Each doctor who has spoken before TV cameras and reporters this morning has described similar things: Pellets, small BBs, headless nails -- projectiles they believe were packed with the bombs, removed from some patients by the dozens.

“My opinion is that most of them were in the bomb,” said Dr. George Velmahos, trauma chief at Massachusetts General Hospital. “I think it’s unlikely they would be so consistent if they were pulled out from the environment.”

Dr. David P. Mooney, Boston Children’s Hospital trauma director, described deep shrapnel wounds in a 10-year-old being treated there who is in critical condition.

Dr. Ron Walls, chairman of emergency surgery at Brigham and Woman’s Hospital, gave a similar description of the items found, saying that nails about 1 centimeter long and small objects about twice the volume of BBs were removed from several patients. The items “clearly were designed to be projectiles that were built into the device.”

At Boston Medical Center, Dr. Andrew Ulrich said the shrapnel “could be described as buckshot.”


“We are used to a lot of chaos, but this was extraordinary,” said Ulrich, who received word about the blast just moments after starting his shift in the emergency department Monday. “Within minutes 8 or 10 patients arrived.”

Several doctors described at press conferences Tuesday morning the blast injuries that required amputations in some patients. At Boston Medical Center, at least two patients required amputations of both legs.

Nineteen patients, between ages 5 and 78, remain at Boston Medical. Of those, 16 were operated on, 11 with major procedures that could require follow-up surgeries. Ten patients were in critical condition as of Tuesday morning.

Velmahos, of Mass. General, said the lower limbs of some patients treated there were so severe that they were considered “almost automatic amputees,” Velmahos said. In those cases, he said, “we finished what the bomb started.”


Walls of the Brigham said one patient had an amputation below the knee and two others may still lose limbs. In all, the hospital treated 31 patients, 15 of whom were admitted. Nine were operated on and five are in critical condition. Dr. Michael Zinner, chairman of surgery said most injuries were to the lower body, though there was one significant head injury.

Mass. General treated 31 people injured by the blast, including four amputations and eight people who remain in intensive care. Several patients were transferred to Massachusetts Eye and Ear Infirmary.

Doctors and hospitals responded in force, Velmahos said. One physician came straight to the hospital to assist after running the race.

“The experience is obviously overwhelming, we are all extremely sad we are suffering emotionally from what happened to the people of Boston,” he said. “At the same time, we can’t feel but proud because the medical community here at Mass General responded.”
