Zimmer ( ZMH) is on a roll. The orthopedics device maker ended 2006 with a bang, blowing past fourth-quarter estimates and gathering the momentum necessary for even stronger results this year. The company returned to double-digit sales growth in the latest quarter, with revenue jumping 10% to $934 million and beating the consensus estimate for a change. Net income increased at more than double that rate, rocketing 23% to $245 million. Meanwhile, operating profits of $1.02 a share beat Wall Street targets by 3 cents. New offerings, such as the Zimmer's Gender Solutions Knee for women, helped out plenty. "During the year," CEO Ray Elliott said, "we experienced a tremendous flow of new products and reached a Zimmer record 24% of sales from new products -- including $229 million in the fourth quarter" alone. Going forward, Zimmer fully expects that momentum to continue. The company is now projecting revenue of $3.85 billion and profits of $3.95 a share for the coming year. Wall Street was anticipating just $3.81 billion in revenue and $3.90 in profits from the company instead. Zimmer's stock bounced 1.1% to a new 52-week high of $81 a share in after-hours trading following the company's upbeat report.
