On Sunday 2 March 2008, during a World Cup Super-G run at Kvitfjell in Norway, Lanzinger crashed into a gate, tumbling down the steep slope.

[5] After surgery by Dr. Thomas Hölzenbein, his condition was described as "stable", and it was affirmed that Lanzinger "could have died" without the amputation because the leg was virtually dead below the knee.

[8] In 2010, the Norwegian patient advocacy found that Lanzinger had not received adequate treatment for his injuries, and was entitled to monetary compensation from Ullevål University Hospital.

[10] He qualified as part of Austria's delegation to the 2014 Winter Paralympics in Sochi, to compete in Alpine skiing (in the standing category).

Lanzinger announced his retirement during the 2015 IPC Alpine Skiing World Championships, where he took silver medals in the downhill and super-G[12] and bronzes in the giant slalom[13] and Super Combined.
