What is Hip Arthritis?

Hip arthritis is a condition usually associated with advancing age.  However, it may affect anyone at a young age, especially those who are overweight.  Treatments vary depending on the patient’s age and the severity of the condition.  From simple weight management for less serious cases to hip surgery for serious ones. Following medical advice is necessary; so does patient’s awareness of relevant issues on the disease. In hip surgery cases, for example, a recall was made last year by DePuy/Johnson & Johnson of its hip implant brand.  BBC Reports More Than 100 New DePuy Lawsuits in UK over the hip implant product.  It is always good to know not just your treatment options but the inherent and potential risks involved as well.

Hip arthritis is caused by a wear and tear of the cartilage in the hip joint.  The symptoms of hip arthritis may occur sporadically or may directly be affected by weather changes.

Hip Arthritis:  Its Symptoms and Causes

The first signs of the disease may occur in the morning as stiffness and discomfort in your hip section.  Common symptoms may also include pain or difficulty in such daily routines as walking, moving around, climbing stairs and others. The pain is usually felt in the groin, the buttocks or, sometimes, into the knee.   The hip joints are likely to stiffen and get inflamed further aggravating the pain and disability if left for granted.

Wear and tear, inflammation, infection and injury could lead to arthritis.

Treatment of Hip Arthritis

For osteoarthritis, the effects cannot be reversed but pain and disability can be reduced with proper treatment.  Moreover, it precludes the risks of surgery once it turns serious. Treatment may need certain modifications in one’s lifestyle to achieve recovery.

Initial treatment may include:
·         Weight management for overweight patients.
·         Hips must not be strained. Avoid unnecessary or vigorous activity that may strain the joint or muscle.
·         Pain relief treatments.
·         Low-impact aerobic exercises.  Swimming is good exercise as the water buoyancy supports the body weight.  Cycling is good for improving your strength and mobility.
·         Use of assistive devices such as cane or walker.
·         Enough sleep at night or morning naps.
·         Good nutrition.  Avoid food and drinks that trigger pain.

Surgical Treatment

Cedars-Sinai recommends osteotomy for the young and if the arthritis affects a small area only of the hip joint.  In this procedure, the arthritic bone is rotated away from the hip joint to relieve it from weight strain. This provides long-term pain relief while at the same time, the patient gets to retain his hip joint and is spared from the risks of an artificial one.  The disadvantages, however,  are longer rehabilitation and the probability of arthritis developing in the newly aligned hip.

A total hip replacement surgery or arthroplasty  may be recommended for advanced stages of hip arthritis.  The damaged cartilage is replaced with an artificial joint.  Post-operative rehabilitation follows to regain the flexibility and strength of the hip.  Walking is a good post-operative exercise.

With the controversy and lawsuits generated by the hip replacement recall, it is best to keep an open communication line with your surgeon and take initiative to know and understand your treatment options.  In the end, any treatment would only be as good as the commitment patients give to their full recovery.

Metal-on-Metal Hip Implants: A Closer Look

The metal-on-metal design on hip implants was first used by George McKee of Norwich England in 1953.  Following the loosening of components of the metal-on-polyethylene hip implant design, the abandoned metal-on-metal hip design was again considered.  Reportedly though, the US House of Representatives called for an investigation on metal-on-metal hip replacements.



Emerging concerns on the all-metal device began when the device gave a high failure rate.  One of the complications observed as metallosis or metal poisoning.  Symptoms associated with metallosis include soft tissue damage, inflammatory reactions, and bone loss.  Furthermore, patients may also go through hip swelling, trouble in walking and pain in the hip region.

 Grounds for investigation

According to the New York Times August 2011 issue, complaints regarding the metal-on-metal hip implants received by the US Food and Drug Administration were roughly 5,000.  The accumulated number was higher than the combined complaints of the past four years. Also published in the New York Times was the article on the dangers of metal-on-metal hip replacements entitled "Remedy Is Elusive as Metallic Hips Fail at a Fast Rate," which discussed how metal-on-metal hip implants shed debris, causing damage on the tissues around the device.  Also stated in the article, that warnings about the harm the implant may bring were given by researchers but these were not minded.

As stated in a range of reports that the Australia and United Kingdom joint registry detected a failure rate of more than 50% of the average rate of all-metal hip implants. In 2003, DePuy Orthopedics marketed the ASR XL Acetabular System and the ASR Hip Resurfacing System, with metal-on-metal hip designs. It was expected that the device will last for 15-20 years.However, recipients complain of defect-related complications within a few years after implantation.

 Materials of the implant

A metal-on-metal (MoM) implant is made out of metal--- from its ball, stem and to its shell.  Compared to the metal-on-plastic polyethylene plastic articulation, cobalt-chrome has much smaller debris particles and offers high wear resistance.  MoM hip implants are durable enough to last a long time and are suited for physically active and younger patients.

 Steps taken by authorities

The FDA is actively working in several areas to further assess the safety and effectiveness of metal-on-metal hip implants.  As an added measure, they have also asked the device manufacturers to conduct post-market surveillance studies on the all-metal hip systems. Device manufacturers, including DePuy Orthopedics, have ordered hip replacement recalls on their devices.  Patients and surgeons ought to have a closer look on the devices and report right away hip implant failure symptoms.
