EXCLUSIVE Matt Pinfield has one helluva spirit — 4 days after he was struck by a car, he’s telling the horrific story from his hospital bed … and it’s pretty freakin’ inspiring. The former MTV VJ joined us Friday on “TMZ Live” from L.A.’s Cedars-Sinai hospital … where he had multiple surgeries this week, healing from 2 broken bones, facial lacerations and a gruesome head injury. Matt said one second he was crossing a street to his apartment, and the next he was smashed straight-up into the air by a speeding car. He says when he landed he looked down at his leg … which was suddenly pretzel-shaped. The good news, as Matt put it, he’s “blessed to be alive.” Since the accident … he says he’s experienced an incredible outpouring of love and support — and it’s clear his old MTV fans are still down with him. Get well soon, Matt!!
