Ohlund, who leads Canucks defensemen with 24 points in 53 games, played Wednesday in Anaheim, but didn't travel with the team to Phoenix for Thursday night's game against the Coyotes, instead returning to Vancouver for surgery.
"After further consultation with our team doctors it was determined that surgery was the best course of action," Canucks general manager Dave Nonis said in a statement. "The best long-term decision for Mattias and our hockey club is to have this addressed immediately."
Vancouver was in the eighth and final playoff spot in the Western Conference, just two points ahead of Nashville, heading into Thursday night's games.
The bone chips were detected by an MRI exam March 5 and Ohlund said he would take up to a week off to see if the swelling went down before deciding on surgery, which has a four- to six-week recovery time. But he returned three days later, playing Saturday against St. Louis and Monday in Los Angeles, averaging 24 minutes before playing less than 15 during a 4-1 loss in Anaheim.
Ohlund had a similar surgery late in the 2002-03 season and returned to appear in 13 playoff games after missing six weeks and 22 games.
