Hip disease can effect a variety of people from all age groups, media reports say, quoting medical research. A distressed hip joint may cause degeneration of the bone and cartilage, which leads top pain and restrictions in movement, a Reuters report says. Osteoarthritis, rheumatoid arthritis, avascular necrosis, congenital dysplasia, and Legg-Calve-Perthes disease are some of the most common hip diseases that may lead to a hip replacement surgery. On a similar note, the British Medical Journal (BMJ) published an article regarding the poor pre-market testing of metal-on-metal hip replacement devices before being used by patients. The DePuy submitted a response to the BMJ metal-on-metal hip article. The need for total hip replacement surgery is prompted either by severe injury to the hip joint.
Osteoarthritis, one of the most common forms of arthritis in the United States affecting millions of people, causes disintegration of the cartilage that surrounds joints, causing stiffness and pain. Roughly half of all total hip replacement surgeries done every year are from osteoarthritis bone degeneration. Eventually, the loss of the cartilage leads to direct bone contact causing chips and loss of bone material. There are many reasons for osteoarthritis, age being among the top causes.
Rheumatoid arthritis is an autoimmune disease, which means that the immune system attacks healthy joint tissue for an unknown reason.
Avascular necrosis (AVN), also known as osteonecrosis, is a disease entity which commonly involves the hip joint. The end result of this disease can lead to collapse and complete deterioration of the head of the femur, commonly referred to as the ball of the hip joint.
Congenital dysplasia of the hip joint is a condition that results in the deformation, and possible chronic dislocation of the hip joint. The hip joint becomes deformed, leading to an unstable joint. Congenital dysplasia starts at birth, but is an ongoing process, most detectable in adults.
Rather similar to avascular necrosis, Legg-Calve-Perthes disease results in the cut of the blood flow to the bone. This causes deformity and degeneration in the tip of the femur.
A slipped capital femoral epiphysis takes place when the tip of the hip falls off the growth plate causing it to not fit in the hip socket correctly. In cases of slipped epiphsys, the patient usually requires replacement of the hip joint, correcting the deformities.
Over the years hip replacement has made major advances. Patients who used to experience hip disease or injury in the past were forced to live with the pain and discomfort. Total hip replacement surgery, as well as many other surgical and non-surgical alternatives, are able to restore function and mobility to hip joints, enhancing the quality of life for patients. However, doctors and patients should be informed that defective hip devices exist, like the recalled DePuy hip replacement products.
