Thanks, Jeff, and good afternoon everyone. Thanks for joining us for the second time this week following our announcement of the definitive agreement to sell our sports medicine business. Today we will be discussing our first quarter 2012 earnings. Hopefully you've had -- all had a chance to see our press release. I'll start the call by providing some key highlights that led to our 200 basis points improvement in adjusted operating margin and double digit adjusted earnings per share growth. I'll then turn her over to Brian to give more detailed on financial results following by some general comments before kicking it off to Q&A.
The first quarter was highlighted by continued strong performance of our regenerative biologics offering, a return to year-over-year growth in regenerative stimulation and a return to investment and R&D while still maintaining double digit earnings growth.
We also continued to strength our balance sheet which provides a strategic advantage to invest in our spine and orthopedic value proposition. This opportunity or advantage will be further enhanced upon the closing of the strategic divesture of the sports medicine business unit that we announced Tuesday. As we discussed on Tuesday's call, the sale of our sports medicine business unit will enable us to divest a portfolio asset that was not integrated into our business as a sales and EBITDA multiple, higher than our pre-announcement corporate trading multiple.
Net proceeds will be used to pay down debt, which significantly deleverages the company and increases our borrowing capacity that will help accelerate the enhancement of our value proposition. That proposition is all about offering repair and regenerative solutions for the spine and orthopedics markets with extremely exciting emerging biologics technologies. All of these emerging technologies can be distributed for both the spine and the orthopedics markets.
Following the close of transaction, our margin profile at both the gross and operating margin levels will significantly improve. We expect the volatility of earnings from ongoing operations will also decrease as the results associated with the sports medicine business will be reported as discontinued operations.
I will start today with our top line results. Total strategic product sales were $143.1 million in the first quarter of 2012, up 4% on a reported basis from $137.8 million in the first quarter of 2011 and 5% on a constant currency basis.
Starting with spine, our repair implants and regenerative biologics increased 5%. These results were driven by stronger, regenerative biologics revenue growth which was partially offset by weaker implant sales. In addition, the stabilization of the regenerative stimulation business continued, and we in fact returned to growth with a 2% increase from the same period of last year.
Notable in the quarter was our continued success with our proprietary, Trinity Evolution, Cell Based Allograft as surgeons are looking for safe alternatives to allograft in BMP-2. We are thrilled to be able to offer the right product from the right partner at the right time. To ensure continued success in cell-based biologics, we initiated our co-development investment with our partner, MTF, during the quarter, more on this in just a bit.
Partially offsetting the strength in biologics was our spinal implants business, which was impacted by low to mid-single digit pricing pressures. While we expect these challenges to continue at least in the near term, we are looking to improve our product cadence launch, or product launch cadence.
For example, at the end of the first quarter we initiated a full market launch of our Firebird Performing System. In addition we continue to work towards optimizing and expanding our distribution footprint. In particular with our unique mix of implants to repair the spinal and anatomy alone with biologics and stimulation solutions to regenerate bone, we believe we have a unique value proposition for our customers and ultimately patients.
We will continue to invest in products and new technologies that enhance its value proposition as evidenced by our recent development with MTF. Through this agreement, we are collaborating to deliver another natural and novel biologic solution that is complimentary to turning evolution and is responsive to surgeons' increased demand for natural bone grafting.
As previously mentioned, we expect to launch this exciting new tissue form in 2013. Our combined spine revenues worldwide represented 52% of overall top line sales. Moving on to Orthopedics, our revenue was $41 million, up a reported 1% or 4% on a constant currency basis. This increase was led by our internal and external fixation product offering in OUS markets partially offset by lower long bone stimulation sales.
During the quarter, we initiated our international launch of our new Galaxy external fixation system and have received very positive feedback from the initial adopters. We continue to see strong sales growth in our TrueLok Ring Fixation System and we are further investigating in this platform and are excited about some new upcoming technologies in this product family.
In addition, we continue to be encouraged by the initial response of our U.S. internal fixation product launches in the foot and ankle market. We believe that the roll out of the ankle compression nail for hind foot fusions and Lapidus Plate for mid-foot fusions, we can become more of a significant player in a high growth market and create more pull through opportunities for Trinity Evolution.
Overall in the U.S., we look to leverage our expertise in the foot and ankle market to attract quality distributors and sales reps. We have recently established a new sales management team and realigned the sales regions. We are in the process of increasing on the number of reps and expect to see this contribution in the back half of the year.
As with our spine business, we believe our orthopedics hardware product offering to repair bone along with our biologics and stimulation solutions for regeneration creates a unique offering for the patient, surgeon and hospital.
Orthopedics revenue represented 29% of our total sales. Moving on to sports medicine, first quarter sales were $27.1 million, up 10% from $24.7 million in the first quarter of 2011. The first quarter of 2012 includes revenue from the billing capability that was acquired in February 2011, which drove about 4% of the growth. We had no revenues from divested vascu products during the quarter compared to $1.4 million last year. This steam of revenue will be part of the sports medicine divesture as the products are manufactured in the BREG, Mexico facility.
As I mentioned in my opening comment, our overall gross margin for the first quarter was 77% compared to 76% in the first quarter 2011. Gross profit in the quarter was boosted by a favorable product mix, particularly biologics and spine, and higher sales with external repair products in orthopedics. Let me now turn it over to Brian for more financial details including our 16.3 adjusted operating margin, an increased investment in R&D and a 22% increase in adjusted net income. Brian will also cover our 2012 guidance based upon the signing of a definitive agreement related to the sale of our sports medicine business. Brian?
