Band Buzz's member Son Sung Hee received a surgery for his femoral head avascular necrosis.

One representative said today, "Son Sung Hee got a surgery yesterday at a big hospital in Seoul and it was successful."

He continued, "He never bumped into anything but he was in pain even in the iddle of his sleep. So he was receiving treatments and he finally went to get testing at a big hospital. The disease is a very rare disease but it wasn't hard for surgery. He will be hospitalized for about 5~6 more days and will be going home. There will be no changes in Buzz's comeback either."

Femoral head vascular necrosis is a disease where bone tissue is dying.

Buzz recently announced their reunion as they signed a contract with Santa Music.
