Diagnosing Hip Implant Pseudotumors with MARS MRI

The symptoms related to defective metal-on-metal hip implants can be extremely overwhelming for some patients. For many individuals, the device that was supposed to restore their quality of life has instead resulted in pain and immobility. Several of the negative side effects of the metal-on-metal hip implants can be difficult to diagnose. Fortunately, there is now a test available to better monitor and diagnose pseudotumors, a serious condition that often occurs with metal-on-metal hip implants. This test, known as metal artifact reduction sequence magnetic resonance imaging, or MARS MRI, improves on traditional methods used in the past.

Metal-on-metal hip replacements manufactured by companies like Smith & Nephew, DePuy, and Zimmer can cause pseudotumors in some patients implanted with these devices. A pseudotumor is a soft-tissue mass formed when metal particles irritate the tissue around the hip. Symptoms of a pseudotumor can include pain around the hip, swelling around the foot and ankle, joint dislocation, and clicking of the hip implant. In the past, doctors used two methods to detect hip pseudotumors: conventional MRI’s and ultrasound scanning. Both these imaging tests present problems that limit their effectiveness in accurately diagnosing pseudotumors.  Conventional MRI’s often obscure soft tissue,  making a proper diagnosis by MRI difficult. Diagnosis by ultrasound scanning depends heavily on the interpretation of the doctor reading it, meaning that a pseudotumor can go undiagnosed if the scan is read incorrectly. The MARS MRI provides a solution to these problems.

A MARS MRI’s capacity to produce high resolution images provides an enhanced visualization of the soft tissues surrounding metal-on-metal hip implants. The technology used results in far less image distortion compared to other testing methods. This makes the MARS MRI the most accurate test to detect the formation of a pseudotumor. While a MARS MRI cannot prevent the development of a hip pseudotumor, it can help with early diagnosis and intervention. Knowing that metal on metal hip implants can cause pseudotumors, MARS MRI’s promote  better monitoring and represent an important diagnostic tool for patients implanted with these devices.  With a more exact image of the tissue around the hip implant, doctors can provide better advice to their patients about the need for a revision surgery.

Manufacturers of metal-on-metal hip implants ignored the serious risks and complications of pseudotumors caused by their defectively designed products. Our experienced lawyers fight for individuals who have been harmed by the negligence of the manufacturers of these dangerous devices. If you or a loved one has been injured or required revision surgery following a metal-on-metal hip implant or other defective hip device, the attorneys at the Yost Legal Group will investigate your potential claim and lawsuit.

Incompetent Cervix

An incompetent cervix, also called a cervical insufficiency, is a potentially serious condition of pregnancy that occurs when weak cervical tissue causes or contributes to premature birth or the loss of an otherwise healthy pregnancy. This type of condition has been described by experts as a “diagnostic dilemma”. Because an incompetent cervix can often be difficult to diagnose, physicians should be constantly on the alert for this condition.

If there is any suspicion of this condition, a health care provider could recommend preventive medication during pregnancy (progesterone supplementation), frequent ultrasounds and/or a procedure that surgically closes the cervix with strong sutures (cervical cerclage). Medical management of pre-term labor is also extremely important, including attempts to stop labor and, too, to provide corticosteroid injections if delivery becomes imminent (which “matures” premature fetal lungs, giving “preemies” a better chance to breathe successfully once born).

The causes of incompetent cervix vary and must be determined in a timely matter by medical professionals in order to select the proper method of treatment. If proper care is not taken, extreme premature birth can result, which increases risks of complications in the newborn, such as intraventricular brain bleeds and periventricular leukomalacia which can cause cerebral palsy.

The cost of care for a child with cerebral palsy, or any birth injury, is very high. If your child’s brain injury was caused by a complication of premature birth, including cervical incompetence, contact The Yost Legal Group today at 1-800-YOST-LAW (800-403-7259).

Metal-on-Metal Hip Implants and Metallosis

Metal poisoning occurs when toxic levels of metal build up in the body causing damage to tissues, bones, and the nervous system. One type of metal poisoning, called metallosis, can occur as a side effect of joint replacement surgery using metal components such as those in metal-on-metal hip implants. Medical device manufacturers like Smith & Nephew, Zimmer, DePuy, and Stryker began releasing metal-on-metal hip implants in 2006. Since that time, thousands of individuals have experienced the debilitating side effects of metallosis, caused by a product that was supposed to help restore their quality of life.

The risk of metallosis facing users of metal-on-metal hip implants arises due to two distinct aspects of the device: the material and the mechanics. Metal-on-metal hip implants are made primarily of two metals, cobalt and chromium. During everyday activities such as walking or bending over, the components of an implant rub against each other causing friction. This friction wears away microscopic particles of cobalt and chromium debris, which are then absorbed into the bloodstream and surrounding tissue. The metal debris can lead to a number of serious complications to the nervous system and organs, including cognitive impairment, heart failure, infection, and implant loosening. It may also cause damage to bone, tissue, and muscle, typically in the area surrounding the device.

If a patient experiences metallosis symptoms, a simple blood test can diagnose the condition. The results of the blood test will reveal the level of metal ions in the blood. Concentrations of cobalt in the blood higher than 1 microgram per liter signify metallosis, while concentrations of chromium higher than 5 micrograms per liter are also indicative of metal poisoning. Once the diagnosis has been confirmed, the most effective form of treatment is revision surgery. In most cases, a revision requires replacing the entire metal-on-metal device with a ceramic-on-metal or plastic-on-metal implant, and cleaning the affected area. This removes the source of the metal buildup and allows the levels of cobalt and chromium to decrease over time.
