EMPERION™
Modular Hip System
View list of all products
Based on a design philosophy with over 20 years of clinical success, the EMPERION™ Modular Hip System combines a proven design with modern technology. The result is the next step in hip evolution: a simpler, more versatile hip system that delivers enhanced performance.
The comprehensive implants of the EMPERION◊ Modular Hip System are designed to address the sizing needs of nearly any femur, thereby restoring the natural kinematics of the patient’s hip.
An effective implant for both primary and revision procedures
Addresses the proximal/distal mismatch
Offers infinite stem to sleeve version control
Comes in three stem lengths: primary, standard revision, long revision (bowed)
Two offset options for each primary length stem
Two calcar options for standard revision stems: neutral and +10
Three calcar options for long revision (bowed) stems: neutral, +10 and +20
Two sleeve lengths: 40mm and 60mm
Up to 16 different proximal sleeve options for each stem size
The EMPERION◊ system ushers in a new age of proven simplicity. By incorporating cutting-edge technology into the system’s design, the EMPERION◊ system delivers enhanced performance versus competitive systems.
Every EMPERION◊ sleeve uses POROUS PLUS™ HA coating with a 50 micron hydroxyapatite layer applied onto the porous sintered-bead coating. Studies have shown this to be the optimal HA coating thickness to ensure proper mechanical integrity and have optimal attachment strength.1,2 Furthermore, the EMPERION◊ system is the only system of this style that has this type of coating available.
Circulotrapezoidal neck provides maximum ROM with minimal impingement, thereby reducing the risk of dislocation and wear.. 3
The polished bullet tip of the stem reduces the magnitude and increases the distribution of pressure on the bone, resulting in easier stem insertion and possibly less thigh pain.4
