Leg machine may cut painkiller use after broken bone surgery

This study looks at whether using a continuous passive motion (CPM) machine—a device that gently moves the leg—can help control pain and reduce the need for strong painkillers after surgery for certain leg fractures. About 100 adults who have had surgery for a broken hip socket, thigh bone, or shin bone will be split into two groups: one that uses the CPM machine and one that does not. Researchers will track their pain scores and medication use during their hospital stay.
