Traumatic shoulder injuries that result in a patient visit to the ER often contain a secondary injury that can cause pain and discomfort in that part of the body after the primary injury has healed. By focusing on the primary injury, radiologists sometimes miss the secondary injury, which can compromise treatment effectiveness. Trainees in the Brigham and Women’s Hospital Radiology Residency Program developed new protocols aimed at drawing ER radiologists’ attention to the potential presence of secondary shoulder injuries. Better identification of these injuries could lead to improved patient outcomes.
This study demonstrates an important and clinically relevant finding, adding support to the theory that early surgical reconstruction of partially injured ACLs is beneficial for protecting the intact bundle and menisci and promotes patients resuming a normal life. The results of the current study indicate that as the time between partial injury of the ACL and surgery increases, the risk of secondary loosening of the intact bundles and associated lesions increased gradually; therefore, the ruptured band of the ACL should be reconstructed early, which may not result in arthrofibrosis.
The reason women are more prone to knee injuries than men may go beyond differences in muscular and skeletal structure, according to researchers from Oregon State University.
“There are some muscular and skeletal differences between men and women, but that doesn’t explain differences in injury rates as much as you might think,” study author Samuel T. Johnson stated in an Oregon State University news release. “No one has really studied the role of the nervous system the way we have in explaining these differences, specifically the way sensory information is processed and integrated with motor function in the spinal cord.”
“We’re finding differences in nervous system processing,” Johnson stated. “The causes for those differences are unclear, but it may be due to either a biological difference, such as hormones, or a cultural difference such as different exercise and training patterns.”
“Hip arthroscopy is an evolving science,” Charles A. Bush-Joseph, MD, of Midwest Orthopaedics at Rush in Chicago, told Orthopedics Today. “We are clearly better able to more accurately diagnose hip and groin conditions. Industry is catching up. There has been dramatic innovation in the equipment surgeons use to perform these types of procedures, making them more reliable and reproducible.”
French researchers have confirmed that high-impact sport, such as jogging or soccer, increases the risk of total hip arthroplasty mechanical failure, according to a study published in Clinical Orthopaedics and Related Research.
“Since participation in sport is now a reality for a significant number of total hip arthroplasty (THA) patients, surgeons may need to adapt their choices of bearing surfaces in implants to accommodate this growing trend,” the authors wrote.
Most conventional carpal tunnel treatments focus solely on the wrist. This approach is, of course, designed to attempt to reduce symptoms of hand pain, numbness and/or weakness. However, the true cause is rarely sought after, hence, these treatments are often times worthless and, in the case of surgery, can actually make matters worse.
There are many factors that will often contribute to median nerve inflammation, which is primarily responsible for the symptoms seen with carpal tunnel syndrome. It can actually be due to problems or dysfunctions in the structures in and around the neck, the shoulder, the elbow, the wrist and/or hand. This is yet another case of a specific painful condition actually caused by something called a kinetic chain disorder pattern. A fancy name for dysfunctional movement issues anywhere along a chain. In this case the chain being the neck, shoulder, elbow, wrist and hand.
Laser Therapy is an FDA cleared modality that reduces inflammation and ultimately results in pain reduction. Laser Therapy is effective in treating acute pain, chronic conditions and post-op pain.
Laser therapy treatment is safe, painless and fast. Deep Tissue Laser Therapy treatments are administered in 5 to 10 minutes. Typically patients see results after 3 to 5 treatment sessions. Deep Tissue Laser Therapy utilizes your body’s own healing powers by stimulating celluar activity. Despite fast treatment times, laser therapy treatments initiate a healing process that continues to actively reduce inflammation for up 24 hours after treatment.
LiteCure Medical is the preferred brand of professional athletic trainers and is a clinically proven modality. LiteCure Medical is the leader in scientific research and education.
In the study, obese women who exercised while using the AvaCore Rapid Thermal Exchange (RTX palm cooling device) improved their exercise tolerance and cardiovascular fitness.
The cooling devices cooled the palms of the hand and circulating blood, thus pulling heat off the body.
The researchers explain that although the genetic makeup is not altered, DNA molecules change structurally and chemically when a person exercises. An example of this is the DNA gaining more or losing parts of methyl groups that are found on sequences of DNA families.
During the study, DNA within skeletal muscle was taken from people who had just experienced a round of exercise. The DNA showed less methyl groups than it had before the person’s work out. The changes were found in the areas of DNA which work as stopping places for a certain kind of enzymes, called transcription factors. These enzymes are very important in terms of muscles and exercise.
“Although trampolines can be fun for both kids and adults, they pose a high risk for injuries, especially when two or more people jump at one time. Orthopedic surgeons recommended that trampolines not be used in home environments or in outdoor playgrounds because of the high risk of injuries from this activity.”
The AAOS has created an audio public service message as well as a position statement regarding trampoline safety in order to prevent injuries sustained from trampolines, rather than treat them.
