Ross Sander's silver medal at the World Junior Championships was overshadowed by a broken radius bone in his wrist.
Ross Sander underwent surgery to plate and pin his broken bone
The Welshman was taken to hospital after the British team crashed in the Pursuit final against New Zealand.
The Great Britain Junior team had been in superb form in Vienna, Austria, qualifying for the final by edging Australia out of the top medals.
Welsh Cycling president Bill Owen said: "We wish Ross a very speedy recovery from his injury."
Sander underwent surgery to plate and pin his bone under local anesthetic.
He will now hope to recover swiftly and fulfil his aim of becoming one of the youngest ever competitors to be nominated to ride for Wales at the Commonwealth Games in Melbourne.
"Whilst we are disappointed to learn of the crash in the final, we are delighted that Ross has won a World Championship silver medal," Owen said.
"Coming so quickly on the back of his and Matt Rowe's European Gold medals in Italy just two weeks ago, it again shows that Welsh cycling has a very bright future at world level."
