$Bisphosphonates may raise risk of atypical femur fracture$

Bisphosphonates may raise risk of atypical femur fracture

There is growing evidence that supports an association between atypical fractures of the femur- a rare break of the thigh bone, typically without trauma - and the use of bisphosphonates, drugs proven to enhance bone density and reduce fracture incidence caused by osteoporosis.

Patients should limit sporting activities to maintain hip prosthesis

In hip resurfacing the femoral ball in the hip joint is not removed, but instead is trimmed and capped with a smooth metal covering. Young and active patients with arthritis often choose hip resurfacing over total hip replacement to minimize the risk of hip dislocation, and to preserve the bone for a revision surgery should the primary resurfacing fail. However, the long-term effects of sports on a resurfaced hip were unknown.

First comprehensive look at how metal-on-metal total hip replacements fail in patients

A study by Hospital for Special Surgery researchers has provided the first comprehensive look at just how metal-on-metal total hip replacements are failing in patients around the country.

Injuries in overweight and obese children more often from 'low-energy' impact

Obese children are 74 percent more likely to sustain a fracture of the growth plate, the softer end of the bone where growth occurs. A new study presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), involved 224 children visiting a Maryland hospital with a fracture.

New Spine iPad app to be unveiled at AAOS annual meeting

The top-cited, most trusted peer reviewed journal in spinal deformity and dysfunction is now available in a new mobile edition with the launch of Spine for the iPad.

$OATS procedure superior to microfracture in repairing cartilage defects$

OATS procedure superior to microfracture in repairing cartilage defects

A new study has demonstrated that a procedure wherein healthy cartilage is transplanted to fix an area of damaged cartilage (osteoarticular cartilage transplantation or OATS procedure) is superior to the standard of care for repairing cartilage defects. It is thought that fixing such lesions may ultimately help to prevent the onset of osteoarthritis, and get athletic individuals back to sporting activities reliably.

Exercise can reduce pain, improve physical function in individuals with OA

The benefits of exercise in minimizing pain and improving mobility for individuals living with osteoarthritis has been well documented.

Elevated risk of PE occurs within first 7 days after total joint replacement surgery

The elevated risk of pulmonary embolism (PE) - a blood clot that travels from the leg to the lungs - following total joint replacement (TJR) surgery has been well established, yet little is known about the natural course and timing of this potentially fatal condition.

Low-energy handguns can contribute to infection and compartment syndrome

Gunshot injuries are typically categorized as low- or high-energy based on the weapon's missile velocity and mass. Typically, low energy injuries are treated with simple wound care, with or without antibiotics, regardless of the presence of a fracture. In contrast, high energy injuries are treated more aggressively.

Study determines prevalence of vitamin D deficiency among post menopausal women with DRF

Wrist fractures, also called distal radius fractures (DRF), are among the most common osteoporosis-related fractures occurring on average 15 years earlier than hip fractures. As vitamin D deficiency has recently been linked with muscle weakness, increased fall risks, and bone fractures, investigators sought to determine the prevalence of vitamin D deficiency among post menopausal women with DRF.

Telephone support can improve outcomes in high-risk TKR patients

Poor emotional health and morbid obesity are associated with less functional gain following total knee replacement (TKR) surgery. In the new study, "Can Telephone Support During Post-TKR Rehabilitation Improve Post-op Function: A Randomized Controlled Trial," presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), approximately 180 patients were categorized by gender, body mass index (BMI) and emotional health.

$Female soccer players more likely to suffer stress fracture or ligament injury$

Female soccer players more likely to suffer stress fracture or ligament injury

In the U.S., there are nearly three million youth soccer players, and half of them are female. New research presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) found that despite reporting appropriate body perception and attitudes toward eating, elite youth soccer athletes (club level or higher) face an increased risk for delayed or irregular menstruation.

Changes in economy affect orthopedic trauma volume

Previous studies have found that human behavior during a recession is remarkably different than that during a bullish economy. For example, people tend to spend more time focused on working and less time engaging in leisure and recreation activities, resulting in fewer motor vehicle and other accidents.

Study highlights benefits of TKR in elderly patients with osteoarthritis

New research presented at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) highlights the benefits of total knee replacement (TKR) in elderly patients with osteoarthritis, including a lower probability of heart failure and mortality.

Anticoagulation drugs can prevent PE, DVT after total joint replacement

Following a total joint replacement, anticoagulation (blood thinning) drugs can prevent Deep Vein Thrombosis (DVT), a blood clot deep within the extremities, or a pulmonary embolism (PE), a complication that causes a blood clot to move to the lungs.

Study finds 77% of trauma patients with vitamin D deficiency

New research presented at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) found that 77 percent of trauma patients had deficient or insufficient levels of vitamin D.

NYU Langone experts to present at American Academy of Orthopaedic Surgeons annual meeting

Experts from the Department of Orthopaedic Surgery at NYU Langone Medical Center will present their latest research and clinical findings on diseases of the muscle, tendon, bone and joint at the annual meeting of the American Academy of Orthopaedic Surgeons (AAOS), February 7-11 in San Francisco, California.

Study may explain why women have higher rate of ACL injuries than men

Much orthopaedic research has been devoted to determining why women are far more susceptible to knee ligament injuries than men. According to a new study, the answer may lie in geometry - the length and shape of a patient's knee bone - more than gender.

AJRR selects Remedy Informatics to build national hip and knee replacement registry

The American Joint Replacement Registry (AJRR) has selected Remedy Informatics, the leading provider of registries for Life Science, to build a registry to collect data on all primary and revision total joint replacement procedures in the United States. Representatives from AJRR and Remedy Informatics will unveil the new registry at the American Association of Orthopaedic Surgeons (AAOS) Annual Meeting in San Francisco, Feb. 7 – Feb. 11.
