The 'Beverly Hills, 90210' star revealed the 16 year old was admitted to the Thousand Oaks Surgical Hospital in California for an operation to repair a fracture in his foot and reattach a tendon following the nasty accident which left the teenager unable to walk.

She posted a series of pictures on Instagram showing Liam in hospital after the operation and she revealed it had been a success. Tori wrote: "My guy did great ... Surgery was a success [thanks] to Dr. Gifford our amazing foot and ankle surgeon and her team at Thousand Oaks Surgical Hospital."

Tori added: "Now the recovery process begins. It's going to be a long journey but we take it day by day ... Thanks to everyone for checking in with Liam and sending him messages and calls and humour before and after his surgery.

"Meant a lot to him. He felt so loved."

The actress went on to explain how Liam hurt his foot, writing: "To everyone that's asked ... Liam fell down the stairs at home and has been in pain and immobile since. Six weeks [and] no healing we got many opinions and Liam's navicular accessory fractured bone in [the] right foot needed to be removed and then tendon reattached to his main bone with a metal hook rod."

Tori is also mum to Stella, 15, Hattie, 12, Finn, 11, and Beau, six, with her ex-husband Dean McDermott. She recently opened up about parenting in an interview with People, insisting she wants to be her children's "biggest advocate".

She said: "You have to trust yourself as the parent because you're going to be your kids' biggest advocate. And that's why I teach my kids. I'm here for them now but I want to teach them to be their own best advocate when they're adults.

"We're finding out a lot sooner, what delights them, what their interests are and we're not dismissing that anymore. We're not saying what fits one fits all.

"Different kids need different things and different confidence boosters. So we've got to take it one day at a time to get through it."
