The use of cement in partial hip replacements has been linked to a risk of death and heart failure in some patients, researchers from the National Patient Safety Agency have warned.
The experts said such occurrences were rare - but that the issue still warrants investigation.
They examined cases of acute patient deterioration associated with hip hemiarthroplasties with the use of cement to help hold the artificial hip joint in place.
Between 2005 and 2012 there were 62 reports of death or severe harm associated with the procedure in the NHS in England and Wales - one event for every 2,900 operations carried out, they found.
Writing in the journal BMJ Open, the researchers said: "There is a need for stronger evidence that weighs the risks and benefits of cement in hip hemiarthroplasty for fractured neck of femur."
