What’s the problem with the DePuy LPS Diaphyseal Sleeve?

In some patients, the DePuy LPS Diaphyseal Sleeve breaks, or fractures, when the patient puts their full weight on the leg that contains the device and walks.

The U.S. Food and Drug Administration (FDA) says it has received a total of 10 reports about the DePuy LPS Diaphyseal Sleeve’s malfunctioning. They include six reports of the sleeve’s fracturing and four reports of its loosening, which may or may not be attributed to the same device design issue that causes fractures, the FDA says.
