It was her first appearance on "The Sharon Osbourne Show" since her husband was injured in the ATV accident in England on Dec. 8.
Osbourne, 55, fractured his collarbone, eight ribs and a neck vertebra when the 600-pound vehicle he was riding flipped and landed on top of him at his estate in Buckinghamshire, southern England. He spent a week on a ventilator.
Sharon Osbourne said Ozzy had to have an artery transplant because part of his collarbone cut an artery leading to his arm, and he nearly had to have the arm amputated. At one point, he had no pulse.
She said he woke up from a coma and had no sense of smell or taste for a while. She also said he was convinced he had been on tour and had been in New Zealand and in Amsterdam, and in a bomb blast in Wales, for some reason.
Ozzy was also convinced he had bought a sheep dog and was asking about it. Sharon said he is doing much better now and he can't wait to heal enough to get back to the United States and to his fans.
Monday's show featured a tribute to Ozzy that chronicled the former Black Sabbath front man's life before and after the accident.
Meanwhile, MTV said "The Osbournes" reality series would return with five new episodes starting Tuesday, Jan. 27 (10:30 p.m. EST).
"Ozzy, Sharon, Jack and Kelly are back on MTV with all new adventures including Jack's 18th birthday, a trip to the tattoo parlor for some family members, a whole slew of new dogs and cats, massive new construction on the Beverly Hills house, and much, much more," the cable channel said Friday.
MTV, like CBSNews.com, is part of Viacom.
Ozzy Osbourne has canceled his upcoming 20-date tour of Britain to give him time to recover fully from his accident.
