Artificial knees also wear out after a period of time, so as the operations are increasingly done on younger Americans, many will live long enough to almost certainly need a second or even third knee replacement.

$Hip fracture patients should be screened for cervical myelopathy$

Hip fracture patients should be screened for cervical myelopathy

Hip fractures are a common cause of morbidity and mortality in elderly patients. Cervical myelopathy is a common neurological condition that can diminish balance and coordination. In new research presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), investigators screened 28 hip fracture patients and 35 hip replacement patients for cervical myelopathy. Eighteen percent (five) of the hip fracture patients did indeed have cervical myelopathy. None of the hip replacement patients tested positive for the condition.
