Total hip replacement patients are disposed to develop stroke during the first few weeks after the operation, a research in Denmark says. The outcome advises that older people should weigh the advantages of hip replacement compared to the threat of stroke, research says.

Not just stroke but also the complications from hip implant devices used like that of Stryker hip replacement recall. There were reported cases of metallosis, swelling, and pain from metal-on-metal hip implant users. I came across stryker-hip-replacement-recall.com and learned many things about this hip implant device.

The researchers compared more than 66,000 people in Denmark who had total hip replacement to approximately 200,000 people who did not have the surgery. The mean age of those who was part of the study was 72, white, and female.

The hip replacement patients had a 4.4-fold increased risk of hemorrhagic stroke (bleeding in the brain) in the two weeks after surgery, compared to people in the overall population. Also, they will most likely to have an ischemic stroke (from blocked blood flow to the brain) with a 4.7-fold enlarged risk.

The likelihood of ischemic stroke stayed for six weeks after hip replacement and the probability for hemorrhagic stroke lingered higher for almost 12 weeks, according to the study published online by the journal Stroke on November 6, 2012.

The prospect of having a stroke decreased after that time and reverberated to the standard after a year, said Frank de Vries, an assistant professor of pharmacoepidemiology at Utrecht University in the Netherlands.

It was also found out that the drug aspirin reduced the risk of stroke in hip replacement patients by almost 70 percent. Other drugs are ineffective.

Annually, there are about one million hip replacements performed globally, 300,000 of it are done in the United States. The researchers advised that it is significant to assess the risk of stroke in the weeks after the hip operation.

“There is an increasing tendency to decrease the length of hospital stay because of improved therapy and because of strategies to reduce costs and mobilize patients as soon as possible,” as expressed by de Vries in a news release.”It makes sense to evaluate the risk of stroke two weeks after surgery,” he concluded.
