When to Have A Hip Revision Surgery?

What if hip implants fail? This might be one of the questions that patients may have overlooked before going to their first hip replacement surgery. It is important to recognize the outcome of the operation and the probabilities that will occur along with the healing process because it might be a lifetime responsibility of an individual to manage changes to his condition. Usually when hip replacement implants do fail, a revision surgery is needed to remove the old implants and replace them with new components.

In hip replacement surgery, notwithstanding a high success rate, still the, complications do exist. An infection may occur when the doctor neglects its obligation to provide care of the replaced joint. However, if the doctor managed to do his therapeutic care, the infection may still happen brought about by wear and tear of the implanted hip device and this might happen during the course of time. Loosen specs of the implant will create new problems such as instability led by further fractures in the joint and the surrounding area that may affect individual’s daily living activities.

What are the signs and symptoms when one must be prompted to seek hip revision surgery?

The most usual complain of patients are pain and inflammation. It might be indications of either loosen implant, wear or infection in the joints. Now that would be very uncomfortable and tragic to anyone.


How it is treated?


Early diagnostic exams must be encouraged. Professionals have enhanced tools for implant failure. Through x-rays, MRI, CT scans, and other imaging modalities, will help determine the location and the degree of affected areas needed to be examined. With those imaging devices and with the aid of a polymer-based system it can help identify the inflammation that is brought about by wear debris. This mechanism may detect bone loss at its early stage. Together with this tool, an effective anti-inflammatory drug that could serve like a hot spot to polymeric system giving a way to treat swelling and prevent bone loss in early stage of wear.

Moreover, a therapeutic measurement at an early stage will lengthen the lifespan of the implant. The patients should take a closer look at their activity level- neither strenuous nor extreme works, diet or weight management is also observed and any other health risks should be avoided so that complications may be evaded.

Metal Poisoning Resulting from Metal Hip Implants on the Rise, Media Reports

The ban against metal-on-metal hip replacement implants has been extensively demanded by many medical experts, based on the reports by The Guardian. According to the report, there has been primary proof linking MoM hip implants to high failure rates, especially in women.

Recently, there are a considerable number of studies which are conducted to investigate the safety of some types of MoM hip implants, believing that these types of implants may break down faster than implants fashioned from plastic and ceramic parts.

There is a very unique aspect to metal-on-metal hip implants that has been found unsafe to hip implant patients. In the light of recent hip implant recalls, surgeons have come forward to expose high failure rates in many large diaphragm metal-on-metal implants, and the significant damage they cause by way of metal wear debris.

It has been discovered that metal debris causes damage on soft tissues and in and around the hip joint. Various studies have found that it may effect on directly killing the tissues and stimulating an inflammatory process. The tissues surrounding the metal hip have been observed to develop pseudo-tumors in most recipients of large metal-on-metal hip implants.

Benign tumors, which are by-product of pus and scar tissues, are the result when the body is unable to identify the foreign object implanted in the body. The body’s reaction to exposure to metals is known as metallosis.

The inflammatory method affects the body’s immune response by infiltrating the T-lymphocytes, or T-cells, that boost the body’s hypersensitivity response. The magnitude of health apprehensions heightened during this time about cobalt and chromium implants. Cobalt has been known to cause cardiomyopathy, hypothyroidism, and both cobalt and chromium may possibly contribute to neurotoxic outcomes, as well as carcinogenesis, or cancer.

On July 2012, the Rejuvenate and ABG II modular systems have been freely retracted by Stryker.As was stated by Stryker Orthopaedics, there is a possibility of fretting and corrosion where some fragments of these modular Stryker hip alternates meet.

When Stryker Orthopaedics sent out its initial communications on this issue, it specified that revision surgery rates were less than one percent. The data was used by May 28, 2012, however, it is not used already. Rather, Stryker labels the complication rate as particularly low. Although this is intended to sound reassuring, it also tells us they are likely uncertain about the actual failure rate.

Determining whether to have a hip replacement procedure? Better weigh the risks and benefits of it first, to save yourself from further injury.
