Osteoarthritis is a painful disorder characterized by degeneration of articular cartilage, resulting in restrictions on the range of motion and gait disturbances. Osteoarthritis is one of the most common diseases among musculoskeletal disorders and is expected to affect more than 10 million Japanese patients. Osteoarthritis of the hip, which is often secondary to developmental dysplasia of the hip and acetabular dysplasia, causes deterioration in the quality of life and impairs activities of daily living in middle-aged people. Non-steroidal anti-inflammatory drugs are sometimes ineffectual for chronic pain of the hip, in part because our understanding of the pathogenesis of hip pain is quite limited regarding sensory innervation and pain transmitting substances in the hip joint. Although total hip arthroplasty is effective in treating painful hips, the medical cost of this surgical approach is estimated to be well over hundreds of millions of dollars. Aseptic loosening and the need for revision surgery are the other drawbacks of total hip arthroplasty.
The cost to society of surgical treatment potentially could be sharply reduced with the development of new, more effective diagnostic tool for cartilage degeneration. GE discovery 750R is the latest Magnetic Resonance Imaging unit with the highest magnetic field of 3.0 Tesla. Althogh it can perform whole body imaging with fast and high quality, its effectiveness has not been investigated especially in hip disease. The purpose of this study is to clarify the quantitative evaluation of articular cartilage of the acetabulum and the femoral head using research pack 3.0 ( cube T1 rho, ultra short TE, T2 mapping and so on).
