Stryker Orthopedics issued a recall letter on August 19, 2016 for one of its hip implant heads. Stryker sent a letter to medical professionals advising them that the LFIT V40 femoral head was involved in a higher than expected series of product failures. These recalled hip implant components were manufactured between 2001 and 2011. No products were removed from the shelves because they had all either been implant or expired.
The manufacturer has not given much information about the recall circumstances but did state that their had been instances of the femoral stems not fitting the heads. Stryker has had problems with its femoral stem and head junction in the past.
The V40 femoral head is used with several different types of Stryker stems including the Accolade stem. I have personally handled over 100 cases involving defective hip replacement systems. The most recent cases involved metal-on-metal hip replacement systems manufactured and distributed by Stryker, DePuy, Zimmer, Wright, and Smith & Nephew. The typical cases involve metallosis leached from the joints between the femoral head and stem. When there is micromotion between the stem and the head, the metal becomes scratched from the movement and corrosion takes place. This corrosion allows metal particles to leach into the hip compartment. These metal particles cause a condition called metallosis where the positively charged metal ions damage the tissue in the hip compartment. The tissue damage progresses to necrosis or death of the tissue and causes pain and inflammation. Frequently, MRI films will show fluid in the joint. Blood tests are usually ordered to check for high chromium or cobalt levels. Once the metallosis process starts the only cure is surgery to redo the hip. These surgeries are called revision surgeries.
The V40 heads were used in the following Stryker products:Accolade TMZF, Hfx, Citation, LASST, Accolade II, Anato, Secur-Fit Advanced, and LSP76. If you or someone close to you has had or needs a revision surgery as a result of a defective Stryker hip replacement system with the LFIT V40 femoral head, please contact Phoenix Arizona mass tort product liability lawyer Steve Leshner for a free consultation.
