Researchers at New York University and NYU Langone Medical Center have created a novel way to enhance MRI by reducing interference from large macromolecules that can often obscure images generated by current chemical exchange saturation transfer (CEST) methods. http://medicalxpress.com/news/2013-04-method-cest-mri.html Medical research Mon, 29 Apr 2013 14:46:22 EST news286465554 Stems cells taken from just a few grams of body fat are a promising weapon against the crippling effects of osteoarthritis. http://medicalxpress.com/news/2013-04-stem-cells-arthritis.html Arthritis & Rheumatism Sun, 28 Apr 2013 18:50:01 EST news286392514 (Medical Xpress)—Either physical therapy or arthroscopic surgery can relieve pain and improve mobility in patients with a torn meniscus and arthritis in the knee, according to researchers from Washington University School of Medicine in St. Louis and six other centers. http://medicalxpress.com/news/2013-04-physical-therapy-good-surgery-knee.html Diseases, Conditions, Syndromes Fri, 12 Apr 2013 06:37:25 EST news284967439 (HealthDay)—Many U.S. subspecialty practices cannot accommodate patients with mobility impairment, according to a study published in the March 19 issue of the Annals of Internal Medicine. http://medicalxpress.com/news/2013-03-mobility-impaired-difficulty-accessing-docs.html Health Mon, 25 Mar 2013 12:30:04 EST news283430060 The cause of unexplained pain among metal-on-metal hip implant patients is more likely to be tissue damage than wear of the implant, Hospital for Special Surgery researchers have found. The study, performed by Dr. Danyal Nawabi, orthopedic surgery fellow, and research collaborators at HSS, will be reported at the upcoming annual meeting of the American Academy of Orthopaedic Surgeons, March 19-23, in Chicago. http://medicalxpress.com/news/2013-03-hip-implant-patients-unexplained-pain.html Surgery Wed, 20 Mar 2013 01:00:03 EST news282938974 Many middle age and older adults have disabling knee pain due to a tear in the meniscus, an important supporting structure in the knee that is often damaged in patients with underlying knee osteoarthritis. In the United States, more than 450,000 arthroscopic meniscal surgeries are performed each year to treat meniscal tears. However, there is little data available to clinicians who must decide with their patients whether it is best to treat tears with surgery or with physical therapy. Now, new research from Brigham and Women's Hospital (BWH), suggests that physical therapy (PT) may prove just as effective as surgery for some patients. These findings are presented at the annual meeting of the American Academy of Orthopedic Surgeons and simultaneously published online in the New England Journal of Medicine. http://medicalxpress.com/news/2013-03-surgery-option-meniscal-osteoarthritis.html Diseases, Conditions, Syndromes Tue, 19 Mar 2013 04:50:01 EST news282886586 (HealthDay)—Implementation of a quality improvement program correlates with a sustained reduction in unnecessary referrals for adolescent idiopathic scoliosis (AIS), according to a study published online Feb. 18 in Pediatrics. http://medicalxpress.com/news/2013-02-unnecessary-referrals-scoliosis-teens.html Pediatrics Tue, 19 Feb 2013 16:10:01 EST news280511246 (Medical Xpress)—We know high-fat, high-sugar foods cause obesity and promote heart disease, but most people don't realize that sugar and fat also contribute to conditions like osteoporosis by weakening bones. http://medicalxpress.com/news/2012-12-fruit-holiday-stocking-bones-strong.html Health Mon, 24 Dec 2012 06:40:01 EST news275551835 (Medical Xpress)—On the morning January 13th, 2013, 25,000 people will meet at the George R Brown convention center for the biggest one day sporting event in Houston.  Many of you will be running 26.2 miles for the first time.  "As more people attempt this wonderous feat, the risk for injury to someone in the field goes up," says Dr. Scott Rand, with the Methodist Center for Orthopedic Surgery. The volunteer medical staff does a great job of doing everything possible to ensure your safety, but you can go a long way towards helping yourself and making your run as safe, comfortable and enjoyable as possible if you follow a few simple tips.  http://medicalxpress.com/news/2012-12-safe-marathon.html Health Thu, 20 Dec 2012 08:03:44 EST news275213014 Female athletes, particularly those involved in high level college sports at the NCAA Division I level, are particularly prone to a trio of medical issues called the "female athlete triad." A new study conducted by sports medicine researchers at the Medical College of Wisconsin found there are some possible shortfalls in the methods used to screen these athletes for the triad, and that could put athletes at risk for lifelong health problems. http://medicalxpress.com/news/2012-06-female-college-athletes-screening-health.html Health Wed, 06 Jun 2012 12:55:33 EST news258206066 A study involving 27 orthopedic surgery residents suggests that surgical residents are often fatigued during their awake time, according to a report in the May issue of Archives of Surgery. http://medicalxpress.com/news/2012-05-surgical-residents-fatigued.html Surgery Mon, 21 May 2012 16:00:14 EST news256815656 The odds that someone undergoing spinal surgery at a particular hospital will have to be readmitted to the same hospital within 30 days is an important measure of the quality of care patients receive.

With the aging population in the western world, there are more patients undergoing orthopedic surgery than ever before. This makes understanding the risk of complications from orthopedic surgery exceedingly important. However, there is a lack of data investigating the incidence of thrombotic and bleeding complications in orthopedic surgery. http://medicalxpress.com/news/2011-08-patients-coronary-artery-disease.html Cardiology Tue, 30 Aug 2011 11:21:59 EST news233922097 A study published in the current issue of Cell Transplantation (20:5) investigating optimal routes for transplanting neural stem/progenitor cells (NS/PCs) in animal models of spinal cord injury (SCI) has demonstrated that intralesional (IL) injection conferred benefits over intravenous injection (IV) and intrathecal (IT) injection.

In a second HSS study, investigators say they have developed a tool to measure outcomes that they hope can be refined and used worldwide. Both studies will be presented at the International Symposium on Brachial Plexus Surgery, which will be held in Lisbon, Portugal, May 19-21. http://medicalxpress.com/news/2011-05-tool-outcomes-arm-surgery-devastating.html Other Fri, 20 May 2011 05:26:28 EST news225087966
