The EMPERION Modular Hip System metal-on-metal hip joint replacement device is utilized in primary and revision surgeries of patients afflicted with damaged hips. It is manufactured by Smith & Nephew Inc. of Memphis, Tennessee, and initially approved by the U.S. Food and Drug Administration (FDA) in November, 2004.
The device, designed to be implanted without cement, may be used in primary or revision hip replacement cases where the rehabilitation of hips damaged by fracture, a noninflammatory degenerative or inflammatory joint disease, or trauma has proven unsuccessful.
The EMPERION Modular Hip System has a modular stem made from a titanium alloy (Ti-6Al-4V). Its neck is circulotrapezoidal in shape. Cylindrical and polished, the sleeves of the EMPERION Modular Hip System are coated with a porous hydroxyapatite surface material.
Smith & Nephew states that this particular stem configuration and construction reduces stress-shielding and micromotion.
