Modular Hip System Offers New Features

A new modular hip system offers innovative features, including optimal sizing of the joint implant to more accurately match the implant to a patient's anatomy.

The Emperion modular hip system is intended for primary and revision total hip arthroplasty, and uses a titanium press-fit stem. Innovative features of the implant include a circulotrapezoidal neck design that allows for a greater range of motion, a 50-micron hydroxyapatite layer applied onto the porous sintered-bead coating, and a bullet-tip shaped stem that reduces thigh pain and makes insertion of the device easier. The system feature easy-to-use, color-coded instrumentation to improve efficiency during the procedure.

Oxinium is based on a unique and advanced bearing product technology. It is created through a manufacturing process that enables zirconium alloy to absorb oxygen and transform to a ceramic on the surface, resulting in a material that incorporates the best features of ceramic and metal while avoiding the limitations associated with either material. The result is a revolutionary technology used in the production of components of knee and hip implants that exhibit superior performance characteristics due to the technology's hardness, low friction, and resistance to roughening and abrasion.

The Emperion hip system was developed by Smith and Nephew (Memphis, TN, USA). It is the only modular hip system that can be used with Smith & Nephew's proprietary Oxinium femoral heads.

"The Emperion system provides me with the versatility to reconstruct the hip joint in a simple, straight-forward manner, while still employing less invasive or tissue-preserving surgical techniques, said Dr. Bertrand Kaper of the Yavapai Medical Center (Prescott, Arizona, USA). "It takes the evolution of hip replacement surgery to the next level of clinical success.”
