Orthopedics maker Zimmer Holdings (UNKNOWN:ZMH.DL) has had a tough time lately. Its sales have slumped as areas such as hip devices and spinal produces have seen revenue decline. While Zimmer's stock has soared year-to-date, this company has been hit by pricing pressures and tough competition in the industry.

Is a turnaround coming in the form of acquisitions? Zimmer agreed to acquire German device maker Normed Medizin-Technik this week, a move that comes on the heels of the company's earlier purchase of small American device company Knee Creations this year. Can these two buys put a spark back in Zimmer's sales? Motley Fool contributor Dan Carroll and health care analyst Max Macaluso discuss what you need to know below.
