They rushed him back immediately on a gurney, a swarm of doctors and nurses descending upon my tiny, terrified boy. I was pushed into a sterile waiting bay, left to pace the linoleum floor with my hands covered in cold sweat.

An hour later, the heavy curtain to Bay 4 pulled back. An ER attending physician, a tall man with a grim, tightly controlled expression, stepped out.

“Mrs. Thorne?” he asked quietly. I jumped to my feet, my heart hammering against my ribs.

“Yes. Is he okay? Can he breathe?” I asked breathlessly.

“We’ve stabilized his oxygen levels and administered IV medication for the pain,” the doctor said, his voice lowering to ensure our privacy.

“Your son has a severe, displaced fracture of the seventh rib on his right side,” he explained. He turned the tablet to show me the stark black and white X-ray.

There, clear as day, was a jagged, horrific break in the smooth curve of my son’s ribcage.

“The bone snapped inward,” the doctor explained, pointing to the image. “It narrowly missed puncturing his lung by less than a centimeter.”

“If it had, his lung would have collapsed, and given his oxygen levels when you arrived, it could have been fatal,” he added.
