(CNN) — “Cake Boss” star Buddy Valastro is revealing the details of the  “terrible accident” that mangled his hand and landed him in the hospital.

“I was involved in a terrible accident a few days ago,” the baker and TV personality wrote on Instagram. “What do you think of my new accessory?”

The accompanying photo showed Valastro in a hospital gown with his right hand heavily bandaged.

A representative said Valastro’s hand was injured when he tried to repair a malfunctioning pin setter in the bowling alley at his New Jersey home on Sept. 20.

His hand got stuck in the machinery and, unable to withdraw it, he watched as it was impaled three times by a 1½-inch metal rod between the ring and middle fingers.

Valastro’s sons — ages 13 and 16 — used a reciprocating saw to cut through the rod and release their father, the rep added.

Valastro underwent emergency surgery at Morristown (N.J.) Memorial Hospital and a second surgery at Hospital for Special Surgery in Manhattan.

“It will be an uphill battle as it’s Buddy’s dominant right hand and he will need prolonged recovery & therapy,” the representative said.

Valastro is a renowned baker and a staple on several food-related reality and competition TV programs.
