Swiss alpine skier Marc Gisin, who lost nearly all his teeth in a serious crash during an International Ski Federation (FIS) World Cup downhill in Val Gardena in 2018, has announced his retirement.

Swiss Ski revealed that Gisin had never completely recovered from injuries sustained in the horrifying 120 kilometres per hour crash.

Gisin had to be airlifted to hospital following the accident after suffering numerous injuries, including fractured ribs and minor fractures of his spine.

His condition was so severe that he had to be intubated before he was placed in intensive care at Lucerne Cantonal Hospital.

The 32-year-old twice placed fifth at the famed Hahnenkamm downhill in Kitzbuehel but was better known for his dramatic crashes that often left him sidelined for months.

He tore an anterior cruciate ligament during a 2012 crash in Crans Montana and suffered a concussion with brain bleeding in 2015 in a crash in Kitzbuehel before the dramatic incident in December 2018.

"Unfortunately, his body never completely recovered from the serious accidents," Swiss Ski said in a statement.

"For this reason, Marc Gisin is retiring."

Gisin’s sister, Dominique Gisin, won an Olympic gold medal in the downhill in Sochi 2014 before retiring.

Another sister, Michelle Gisin, who remains active on the women’s FIS Alpine Ski World Cup circuit, won a gold medal in the women’s combined event at Pyeongchang 2018.

Marc Gisin also competed at Pyeongchang 2018, finishing 21st in the men’s downhill.
