While attending a book party in New York City on Monday, Bushnell told The New York Post's Page Six that she was rushed to the hospital recently after suffering an equestrian accident.
"I was doing dressage on this muscular horse. It started bucking, and I had to make the choice to come off," the writer said. "I cracked my pelvis, and spent two nights in the hospital."
While Bushnell admitted that her recovery from the tumble has been difficult at times, she insisted that she would not let it discourage her from returning to horse riding.
"I couldn't walk for a few weeks... but I am still getting back on the horse," she declared.
Bushnell's 1997 book Sex and the City, which featured a collection of essays, proved popular and was eventually adapted into an HBO series starring Sarah Jessica Parker as columnist Carrie Bradshaw.
While the half-hour drama concluded in 2004, the franchise has continued with a feature film adaptation and later a sequel.
A literary prequel titled The Carrie Diaries, focused on Carrie Bradshaw's adolescence, debuted last spring. A follow-up, Summer and the City, was released this week.
