Patients who go through total hip replacement seriously increased their risk for stroke in the first few weeks after surgery, according to a new study in Denmark. The effect of the study denotes that people should think twice before undertaking a hip replacement because of the risk of getting a stroke alongside the advantages that the operation might do.


Stroke is only one among the many complications that you may experience, there are other harmful effects from the hip implants used, just for instance, Stryker Rejuvenate Modular hip recall. Metal poisoning, inflammation, and pain were just among the complaints of the metal-on-metal recipients. The online site, offers helpful articles about this device.


The study was comprised of almost 66,000 people who had total hip replacement and who were compared to nearly 200,000 individuals who did not have the surgical procedure.The average age of the people in the study was 72, and mostly, female and white.


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. They also had a nearly 4.7-fold increased risk of ischemic stroke (from blocked blood flow to the brain) during that time, the study authors found.


The chance of ischemic stroke persisted higher for six weeks after the operation while in the case of hemorrhagic stroke it will dwell for 12 weeks, as stated by the journal Stroke on November 6, 2012.


After that time, the feasibility for stroke to happen will decline and resumed to normal after one year, as reported by Frank de Vries, an assistant professor of pharmacoepidemiology at Utrecht University in the Netherlands.


The researchers also learned that aspirin lessened hip replacement patients’ probability of getting a stroke at 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 said it was essential to measure the risk of stroke in the weeks after hip replacement surgery.


“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.
