Before Pagliaro had a hip replacement, pain made it difficult to work. Maggie Starbard/NPR Every year more than a quarter of a million Americans have total hip replacement surgery. Its almost always a successful operation that frees patients from whats often described as disabling pain. But in recent years, theres been lots of discussion on the Internet about “anterior approach” hip replacement, a surgical technique thats different than the standard procedure. Its one that proponents say can lead to quicker recovery, three to four weeks compared to six to eight weeks for typical surgery. Some people have been willing to give it a try, even though theres no conclusive research showing its better than other approaches. Take the case of Mich
Hip Revision Surgery Total hip implant demonstrating socket, liner, ball and stemTotal hip replacement or total hip arthroplasty is a surgical procedure in which an artificial hip joint prosthesis is implanted to replace an arthritic or damaged joint. A hip replacement includes an artificial hip socket and femoral stem with an attached femoral head picture at right.Hip replacement surgery is very effective in relieving pain and improving patient function and quality of life. However, hip replacements may “wear out” or fail for other reasons, and occasionally require a “hip revision surgery.” In hip revision surgery, the worn out or failed prosthesis is replaced with a new hip implant.
Over the past two decades, the number of Americans having total hip replacements has more than doubled, to more than 300,000 a year. Though most patients eventually walk again without pain or the aid of a cane, recovery and rehabilitation can be rigorous, painful and lengthy. The surgery is extensive: As its name suggests, it involves removing the joint — the damaged bone and cartilage — and replacing it with prosthetic parts made of metal, plastic or ceramics. Typically, surgeons enter the joint from the rear, which requires cutting through muscle and cartilage. But with a relatively new procedure, surgeons enter from the front and only stretch the muscles aside, avoiding the cutting and minimizing pain and recovery time. According to those who use this anterior technique, the benefits are substantial.
There are a large number of hip implant devices on the market. Each manufacturer has different models but each style falls into one of four basic material categories:metal on plastic polyethylene or UHMWPEmetal on metal MoMceramic on plastic UHMWPEceramic on ceramic CoCThese category names reference the materials used for the implant bearings. The stem and ball fit into and articulate against the cup or acetabulum. Each component can be made of one of several materials.
In the next 5 to 10 years, orthopaedic surgeons can expect to see a jump in the number of patients who require implant revision surgery, according to Wayne G. Paprosky, MD, FACS, associate professor of orthopaedics at Rush University Medical Center. Although the number of individuals who receive total joint arthroplasty is skyrocketing, the increase in revisions isn’t tied just to population growth. Dr. Paprosky and other attendees of the 2007 AAOS/NIH Osteolysis and Implant Wear Research Symposium delved into the clinical reasons for joint revision surgery and explored issues such as the diagnosis and treatment of osteolysis, the challenges surgeons face during revision surgeries, and the continuing need for research into these complex subjects.
Hip replacement surgery hip arthroplasty has been touted by many experts as one of the most significant medical device innovations of the last 40 years. It has helped millions of people overcome painful arthritis, recover from hip fractures and improve their quality of life. However, hip implants do not come without risk or complications. A growing number of implant recipients have experienced implant failure and other severe complications associated with their hip replacement.
