Medical Implant Devices Skate Through Review Process, Studies Claim

Posted 30 Sep 2014 by Drugs.com

MONDAY, Sept. 29, 2014 – Every day, people receive medical implants – artificial valves, hip replacements, surgical mesh and the like – that may not have been rigorously tested before or after their approval by the U.S. Food and Drug Administration, two new studies contend. The studies – conducted by prominent nonprofit groups and published online Sept. 29 in JAMA Internal Medicine – lay the blame for inadequate medical device testing on lax oversight by the FDA. Manufacturers didn't submit any scientific evidence on the safety or effectiveness of 42 out of a sample of 50 new implants in their applications to the FDA, according to a review conducted by the nonprofit National Center for Health Research. The FDA cleared the implants for use in humans. "If you are a doctor who wants to know what the scientific evidence is that this device is safe and effective, there is no publicly ... Read more

Anesthesia Type May Affect Recovery From Hip Fracture Repair

Posted 24 Jun 2014 by Drugs.com

TUESDAY, June 24, 2014 – Hip fracture surgery patients who are given regional anesthesia have a slightly lower risk of death and a slightly shorter hospital stay than those who receive general anesthesia, a new study shows. Regional anesthesia involves delivery of anesthesia directly to the affected part of the body without putting the patient "to sleep." Researchers analyzed data from nearly 57,000 patients over age 50 who had hip fracture surgery in New York State between 2004 and 2011. Of those patients, 28 percent had regional anesthesia and 72 percent had general anesthesia. The death rate after 30 days was 5.3 percent for regional anesthesia patients and 5.4 percent for general anesthesia patients, which is not statistically significant. The average length of hospital stay was six days for regional anesthesia patients and 6.3 days for general anesthesia patients. The findings ... Read more

Weight Loss May Boost Success of Joint-Replacement Surgery

Posted 18 Mar 2014 by Drugs.com

TUESDAY, March 18, 2014 – Losing or gaining weight after joint-replacement surgery affects the ultimate success of the operation, according to a new study. Patients who lost weight after knee-replacement surgery had much better results in terms of pain, function and activity levels than those who maintained or gained weight, the researchers found. But in both knee- and hip-replacement patients, weight gain was associated with poorer outcomes, according to the study, which was presented at this month's annual meeting of the American Academy of Orthopaedic Surgeons in New Orleans. "Based on our findings, as physicians, we should convey to our patients the importance of maintaining good health and an appropriate weight, and we should help them in any way we can to achieve this goal," said Dr. Geoffrey Westrich, senior investigator and director of research in adult reconstruction and joint ...

New Knees, Hips May Also Help the Heart

Posted 11 Mar 2014 by Drugs.com

TUESDAY, March 11, 2014 – A knee or hip joint replacement may provide a surprising benefit: better heart health. In a study of 2,200 people older than 55 with arthritis, researchers found that the odds of a serious heart problem or death were 37 percent lower in people who had a knee or hip replacement compared to those who didn't have such surgery. "Arthritis is associated with an increased risk of cardiovascular disease and cardiovascular death. It is possible that arthroplasty can reduce these risks," said lead study author Dr. Bheeshma Ravi, a physician in the division of orthopedic surgery at the University of Toronto. Total joint arthroplasty is the medical name of the surgery to replace a hip or knee joint. Patients in the study had osteoarthritis, the type of arthritis associated with normal wear and tear on the joints. While the study found a link between having joint ... Read more

Hip Replacement Safe for Patients in Their 90s, Study Finds

Posted 11 Mar 2014 by Drugs.com

TUESDAY, March 11, 2014 – As the population ages, more and more older people might need to have their hip joints replaced. But how old is too old to undergo the surgery? According to a new study, patients in their 90s who need total hip replacement can have results comparable to younger patients. "Our data show that [older] patients have the ability to do better than we expected," said lead researcher Dr. Alexander Miric, an orthopedic surgeon at Kaiser Permanente, in Los Angeles. Over a 10-year period, Miric and his colleagues compared the results of hip replacement surgery in 183 patients who were aged 90 and above to the results of more than 43,000 other total hip replacement surgeries performed on younger patients. "Being in your 90s need not disqualify you from having a hip replacement surgery," Miric said. He is scheduled to present the findings Tuesday at the annual meeting of ... Read more

Hormone Therapy May Cut Risk of Repeat Joint Replacement Surgery in Women

Posted 23 Jan 2014 by Drugs.com

THURSDAY, Jan. 23, 2014 – Women who start hormone replacement therapy after having had hip or knee replacement surgery may cut their risk of needing another procedure in the same joint by nearly 40 percent, a new study suggests. About 2 percent of those who have a hip or knee replacement need another surgery within three years. Most of these additional procedures are needed because of a complication known as osteolysis, which happens when tiny pieces of the implant seep into the tissue around the implant, causing inflammation that destroys the bone around the implant, the British researchers explained. "There is evidence that drugs like hormone replacement therapy, used usually to prevent osteoporosis and fractures, might have a beneficial effect on implant survival in patients undergoing knee or hip replacement," said lead researcher Dr. Nigel Arden, director of musculoskeletal ...

Death Rate After Hip, Knee Replacements Has Dropped Sharply: Study

Posted 10 Jan 2014 by Drugs.com

THURSDAY, Jan. 9, 2014 – The risk of death from hip- or knee-replacement surgery has dropped substantially in recent years, a large new study finds. Dutch researchers found that since the early 1990s, death rates have fallen by almost two-thirds among Danish adults having the procedures. The length of patients' hospital stays also dropped – from more than two weeks, on average, to about one week. The study did not dig into the reasons for the improvements, but it's likely that changes in post-surgical care have had a big impact, said lead researcher Arief Lalmohamed, of the Utrecht Institute of Pharmaceutical Sciences in the Netherlands. Those changes, he said, include new blood-thinning medications that help prevent patients from developing potentially dangerous blood clots after surgery. Clots can, in some cases, lead to a heart attack, stroke or pulmonary embolism (a blood clot in ... Read more

Complications More Common Than Thought for Type of Hip Surgery

Posted 25 Mar 2013 by Drugs.com

SATURDAY, March 23 – The complication rate for hip arthroscopy, a minimally invasive surgical procedure to repair damage to the inside of the joint, is higher than previously thought, a new study finds. The researchers said previous reports on complications were not comprehensive and did not include new surgical techniques, such as repair of the hip labrum. They suggested their findings could help doctors prevent complications associated with hip arthroscopy in the future. The new study analyzed information on nearly 600 hip arthroscopies that took place at three hospitals between January 2011 and April 2012. Patients, whose average age was about 32, included an equal number of men and women. Researchers took participants' individual diagnosis, demographic information and procedure into account. "The overall complication rate after hip arthroscopy was 7.2 percent, which is higher than ... Read more

Joint Replacement May Reinvigorate Sex Life

Posted 19 Mar 2013 by Drugs.com

TUESDAY, March 19 – Although most people get a total hip or knee replacement to decrease pain and move around more easily, a team of orthopedic surgeons has discovered an unexpected benefit: people enjoy sex more after surgery. A new study found that total hip or total knee replacement surgery improved self-reported sexual function in 90 percent of patients. Study author Dr. Jose Rodriguez, director of the Center for Joint Preservation and Reconstruction at Lenox Hill Hospital in New York City, created a survey to learn more about how sexual experience was affected by getting a new joint. He said he thought that if he brought up the topic by asking questions about sexuality, people would respond. And they did. "Most patients won't bring up the topic on their own," he said. Rodriguez said that many patients fear they'll damage the new joint if they have sex, but don't ask any questions ... Read more

Health Tip: Protect Your Hips From Arthritis Damage

Posted 11 Mar 2013 by Drugs.com

-- Osteoarthritis can strike the hip following years of wear and tear that causes damage to the joint. Protecting the hips from further stress can help reduce damage. The American Academy of Orthopaedic Surgeons lists these suggestions to help slow the progression of hip arthritis: Allow your hips to rest, and don't overuse the joints. Practice a physical-therapy regimen that includes gentle exercises such as swimming, cycling and water aerobics to maintain joint function and motion. Try taking nonsteroidal anti-inflammatory drugs. Make sure you get plenty of sleep every night. If you are overweight, lose weight. Consider using a cane to ease strain on the joint if your arthritis worsens. Read more

Women at Greater Risk for Hip Implant Failure, Study Finds

Posted 18 Feb 2013 by Drugs.com

MONDAY, Feb. 18 – Overall, the vast majority of total hip replacement surgeries are successful, but according to the results of a new study, women are at greater risk than men for implant failure after this procedure. Researchers noted this was true even after taking other individual risk factors into account. They said their findings could help doctors better manage the anatomical differences between men and women. "The role of sex in relationship to implant failure after total hip [replacement] is important for patient management and device innovation," the study authors wrote in the report published online Feb. 18 in JAMA Internal Medicine. The researchers, led by Maria Inacio, of the Southern California Permanente Medical Group in San Diego, tracked more than 35,000 hip replacements that were performed at 46 different hospitals over an average follow-up period of three years.

Startling Differences in New-Hip Estimates: Study

Posted 11 Feb 2013 by Drugs.com

MONDAY, Feb.11 – Advance estimates for a standard hip replacement at a top-ranked U.S. hospital can run as low as $12,500 or surpass $105,000, if you can actually obtain a quote, a new study finds. Many hospitals can't – or won't – provide straightforward price quotes in advance of medical procedures, the researchers found. And when they do supply estimates, the costs see-saw widely, even between comparable facilities, they said. For instance, at general hospitals they found a nearly $115,000 differential for a new hip, with total fees from $11,100 to about $126,000. "On the quality front, there's actually a lot of data available," noted study co-author Dr. Peter Cram, an associate professor and director of the division of general medicine at the University of Iowa Carver College of Medicine in Iowa City.

Certain Arthritis Patients Fare Worse After Joint Replacement: Study

Posted 28 Nov 2012 by Drugs.com

WEDNESDAY, Nov. 28 – Patients with rheumatoid arthritis are more likely to suffer hip dislocation after hip replacement surgery than those with osteoarthritis, a new study says. In addition, rheumatoid arthritis patients have a higher infection risk after total knee replacement than osteoarthritis patients, the study authors found. Rheumatoid arthritis, which is felt throughout the whole body, is caused when a person's immune system attacks his or her own tissues. Osteoarthritis, which is usually felt only in the joints, is caused by wear and tear on the body. For the study, the investigators analyzed the findings of 40 studies published between January 1990 and December 2011. The studies included arthritis patients aged 18 or older who had hip or knee replacements. The findings are published in the Nov. 28 online edition of Arthritis & Rheumatism. "Joint arthroplasty is successful in ... Read more

Hip Surgery Increases Stroke Risk in Older Patients: Study

Posted 9 Nov 2012 by Drugs.com

FRIDAY, Nov. 9 – Patients who undergo total hip replacement are at greatly increased risk for stroke in the first few weeks after their surgery, a large new study says. The findings suggest that elderly people need to weigh the benefits of hip replacement against the risk of stroke, according to the researchers. The investigators compared more than 66,000 people in Denmark who had total hip replacement to nearly 200,000 people who did not have the procedure. The average age of the people in the study was 72. Most were 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 general 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 risk of ... Read more

Hip Resurfacing More Likely to Fail Than Hip Replacement: Study

Posted 2 Oct 2012 by Drugs.com

TUESDAY, Oct. 2 – Hip resurfacing fails in many patients and should not be used in women, according to a large new study. Often recommended to younger patients, hip resurfacing is similar to hip replacement except surgeons don't completely remove the femoral head (the rounded top section of the thighbone). A metal cap replaces the bone that has been removed. Hip resurfacing always has metal-on-metal bearings, while hip replacement uses different types of bearings, such as ceramic, metal or plastic. Researchers looked at data from more than 434,000 hip operations conducted in England and Wales over eight years. Of these, nearly 32,000 were hip resurfacings. They found that the use of smaller femoral head sizes was linked to higher failure rates and, for the most part, resurfacing implants failed more quickly than other bearing surfaces. The only exception was for men with a large ... Read more
