Different People Who are getting Stryker HipsAdverse Local Tissue Reaction in Hip Revision Surgery Patients

A recent research study completed by H. John Cooper and his associates revealed that individuals between the ages of 43 to 77 were at risk for developing metal poisoning and significant on-set pain after a revision surgery involving metal hip replacement devices. The study is entitled, “Adverse Local Tissue Reaction Arising from Corrosion at the Femoral Neck-Body Junction in a Dual-Taper Stem with a Cobalt-Chromium Modular Neck” and has been published by the Journal of Bone and Joint Surgery.

The study shows that immediately following the corrosion of metal hip replacement devices, patients reported experiencing chronic pain for a total of 8.6 months before receiving a diagnosis and revision surgery. When the revision surgery was finally performed, the pain did not stop for patients who underwent the invasive procedure. Instead, some patients suffered from worsened conditions, such as additional fractures, during or after a surgery. Other patients had hips that required an extensive trochanteric osteotomy procedure to remove a hip implant. The results of the research study also indicated increased levels of cobalt, chromium, and titanium in men and women between the ages of 43 and 77 who had received revision surgeries after the corrosion of their metal hip replacement devices. These increased metal levels indicate that patients may already be experiencing forms of metal poisoning.

Pain Following Revision Surgeries with Hip Replacement Devices

Out of all 12 patients involved in the research study, every patient suffered from localized pain in the groin area following his or her revision surgery. A 61-year-old female patient also reported other symptoms, including limping, weakness and swelling. Three other female patients between the ages of 43 and 46 also reported a limp in addition to the groin pain that they suffered in following a revision surgery with a metal hip replacement device.

Experience of Pain in Male Patients

The male patients involved in this research study were between the ages of 63 and 65. These male patients suffered from pain in the groin area, and one male patient also reported experiencing pain in the trochanteric area. The average male patient endured chronic pain for a total of 14.3 months before receiving his revision surgery. In addition, one male patient indicated an extremely high level of cobalt in his bloodstream at a level of 8.9 which compared to the average mean of 6.0. This indicates that corrosion may have caused a severe form of metal poisoning in this male patient.

Experience of Pain in Female Patients

The female patients involved in this research study were between the ages of 61 and 77. On average, female patients reported the experience of pain in other areas of the body in addition to the groin area. The female patients reported the experience of pain in the thigh and buttock area as a result of corrosion of metal hip replacement devices. One 77-year-old female patient experienced pain in the groin, buttock and thigh area for a total of 23 months before her revision surgery was ever completed. Another female patient experienced pain in the groin area, in addition to weakness and swelling, for a total of 20.7 months before her revision surgery was completed.

What the Numbers Mean for People With Existing Stryker Hips

The research study shows that both elderly and middle-aged patients are at risk for suffering from chronic pain before a revision surgery to correct corrosion due to Stryker hip replacement devices. Patients as young as 43 suffered from severe pain for many months prior to their revision surgeries, as indicated by the results of the study. If any patient has suffered from chronic pain and the high costs associated with receiving a revision surgery for a metal hip replacement, he or she can get in touch with a Stryker recall lawyer for additional help. An attorney with experience litigating hip recall cases can help metal hip replacement patients understand their legal rights before and after a Stryker hip revision surgery is completed.
