|Date:07/01/2007 HEALTHWATCH Revolutionary surgery Hip resurfacing: Fewer risks, more benefits. ARTHRITIS of the hip joint is a common problem in India. It occurs due to damage to the joint from various conditions such as Osteoarthritis (wear and tear arthritis), avascular necrosis (death of the bone due to lack of blood supply), trauma or injury (previous hip fractures), infection, rheumatoid arthritis, ankylosing spondylitis and other diseases. It causes severe pain, stiffness, deformity, decreased mobility and severe disability. In India, hip joint arthritis affects even young people leading to disruption of family and social life, inability to work and difficulty in movement.Traditionally, Total Hip Replacement (THR) has been the only treatment for people suffering with hip arthritis for the past 40 years. The surgery is conducted|

Currently, there is little basis to decide between neutral and valgus placement.
We loaded 10 notched cadaveric femur pairs to failure; one side was implanted at 0[degrees] relative to the femoral neck and the other at 10[degrees] valgus. All 20 were dual-energy xray absorptiometry-scanned. Failure load correlated with bone mineral density.
Valgus placement increased the fracture load by an average of 28% over neutral for specimens with normal bone mineral density but had no effect on fracture
The word Arthritis is defined in the dictionary as “inflammation of the joint or joints.” Inflammation is usually in the synovium. The amount of cartilage damage and inflammation varies with the type and stage of arthritis. Normally pain is caused by inflammation in the early stages of arthritis. The cartilage becomes worn away in the later stages of arthritis and the pain often comes from the bone on bone condition when the cartilage is gone. Normally this is the time when there are very few options left to relieve the pain, except a hip replacement.
Osteoarthritis mainly damages the joint cartilage, but there is often some inflammation as well. It does not affect the internal organs. The cause of hip osteoarthritis is not … Read the rest
