He was evacuated to the Barzilai Medical Center in Beersheba, where he underwent surgery for seven hours. His condition was defined as serious but stable.
Seven other troops were injured in the attack. One soldier sustained serious wounds to his head, but his condition later improved and was defined as moderate on Saturday morning. Another soldier was moderately injured and two others were lightly hurt.
The four were hospitalized at the Soroka Medical Center in Beersheba, which released two troops who sustained light wounds throughout the night. A female soldier was treated for shock at the Barzilai Medical Center and was later released.
Noam's mother, Aliza, waited outside the operating room with the other family members.
"I fell asleep and woke up to a different reality," she told Ynet. "For a moment I didn’t know where I was. I can't believe Noam was hurt, that he lost a leg."

The mother spoke of her son, "He's a smiler, an amiable and nice child, who is kind to everyone. He's gentle and the military service made him stronger, but he really wanted to leave.
"He is supposed to be released in August, and we have been counting the months for his leave. At first he didn’t like the base, but he later became accustomed to it."
The Nahal Oz base has been hit by mortar shells more than once. "He always informed me about mortars landing in the area, but told me, 'Mom, you have nothing to worry about.' He said everything would be okay, but I was worried nonetheless.
"Every weekend when he came home, he would hang out with friends. The moment he got out he would visit his friends. He loved playing football, it was his hobby."
'Take the Qassam threat seriously'The mother asked to convey a message to the prime minister and IDF chief of staff.
"It's hard for me to say these words as a mother. I just hope they evacuate them and do something against the terror elements, against those firing the mortars, the people operating against the angels stationed at that base.
"I want them to take the Qassam threat seriously and start working. It's not just my son, but all the soldiers who are there and all the residents living in the area."
Ron Lobel, the Barzilai Medical Center's deputy director, told Ynet that "the soldier arrived at the hospital with a serious injury to both his legs. Our first impression was that he had lost both legs. His condition deteriorated and he was resuscitated. He was then rushed into the operating room, where he was treated by a number of medical teams until 5 am.
"The soldier has been transferred to the recovery room, and his condition remains serious but stable. We were forced to amputate one of his legs, but I hope his other leg has been saved."
Two of the mortars fired Friday nightanded within the base, one hitting the officers' quarters and the other hitting the female soldiers' quarters. Two other mortars landed in open areas in the Sha'ar Hanegev Regional Council.
Shells also landed in the Netiv Haasara area, where there were no reports of injuries or damage.
The Popular Resistance Committees claimed responsibility for the mortar fire, but Hamas later declared that its military wing, the Izz al-Din al-Qassam Brigades, was behind the attack.
