DePuy Recall Draws Attention to Risks of Metal Hip

Хадес — Mon, 03 Jan 2011 17:11:45 GMT

Rehabilitation right after a hip replacement is generally straightforward but it can be critical to be conscious of the priorities at each stage on the operation and recovery to the very best outcome. Due to the fact an osteoarthritic hip is painful this has a series of knock-on effects. A painful joint signifies the musculature which controls that joint are not able to work appropriately so tends to lose some of its strength and assistance with the joint. The joint may also become tight since the pure actions usually are not performed and also the man or woman may well adopt an abnormal gait which becomes an ingrained habit.

Pre-operative education and rehabilitation is essential so the person knows what they are trying to accomplish with their workout routines and gait practice. Range of motion and strengthening physical exercises can be provided along with gait correction. When the gait are unable to be effortlessly corrected by instruction, consideration need to be provided to applying a running aid. Either a stick or even a crutch might be used depending about the degree of service required, held inside opposite hand on the arthritic joint. If the affected individual walks using a excellent routine this is sufficient, but if they still walk poorly they might require two sticks or crutches to attain a reasonable gait routine.

Johnson & Johnson Hip Implant Recall

It’s been over two years since the FDA started getting complaints about the failure of a hip replacement implant manufactured by DePuy Orthopaedics, a division of Johnson & Johnson. Over 93,000 people worldwide have had hip implant surgery with these devices, and the FDA has had over 400 complaints about it since 2008. Apparently, the failure happens early after surgery and a second, painful surgery is then required.

The high early failure rate of these implants (called ASR implants) has been known of for some time. ASR implants are part of a category of implants called metal-on-metal implants that cause debris from wear, inflammation and sometimes even tissue damage.

This is one of many recalls of many of Johnson & Johnson’s best-selling products. The giant pharmaceutical company is clearly in trouble – if you can call any pharmaceutical company whose earnings are down “in trouble.” The fact is, Big Pharma cleans up on meds and products. Last year, DePuy Orthopaedics had sales of almost $5.4 billion – and it’s just a division of J&J! I wonder if when asked what they wanted to be when they grew up in class, the leaders of these giants said, “I want to be the CEO of a huge pharmaceutical company that sells defective products and dangerous medications, and make a fortune doing it.”

Conventional Total Hip Replacement (THR)

Conventional Total Hip Replacement (THR) is a very successful procedure for the treatment of arthritis of the hip, a condition causing considerable pain and loss of movement. The hip is a ball and socket joint, which allows the upper leg to move from side to side, back to front, and to rotate. The joint is made up of the head of the femur (the ball), which fits into the acetabulum (the socket). In the healthy hip, both the head of the femur and the acetabulum are covered with cartilage, a smooth surface which allows the joint to move freely.
