Warsaw-based medical device manufacturer Zimmer-Biomet is purchasing LDR Holding Corporation for $1 billion. The Texas-based company specializes in cervical disc replacement, and Zimmer Biomet CEO David Dvorak said the purchase will bolster Zimmer in the fastest growing segment in the spine industry, according to Inside Indiana Business. Dvorak says there won’t be any major overlap of products. The deal is expected to close in the third quarter of this year. It’s the third big purchase by Zimmer Biomet since March.
