Johnson & Johnson (JNJ) is in talks to acquire medical device maker Synthes in what may be the 125-year-old company's biggest deal ever. Valued at $19.4 billion, Synthes has an operating margin of 35 percent, the highest among medical-products makers worth more than $5 billion in sales, according to Bloomberg data. The acquisition would increase J&J's share of the $5.5 billion orthopedic trauma market to 54 percent, from about 5 percent, and nearly double the company's 11 percent share of the $9 billion spinal-care market, according to analysts at Wells Fargo (WFC) and Sanford C. Bernstein (AB). J&J's image has been hit as a result of over 50 drug and device recalls since the start of 2010.
