SYNERGY

Hip System with options that include: Porous, HA, HA on Porous, and Cemented

Overview


SynergyHipSystem_Overview
SYNERGY One system for Stability, Biomechanical Restoration, and Clinical Results
With over 500,000 stems successfully implanted since 1997, SYNERGY Hip System has been one of the fastest growing hips in orthopaedics.

Why? Because SYNERGY is a complete system, with state-of-the-art options, that utilizes simple, efficient instrumentation.

The SYNERGY Hip System gets initial stability through three-point fixation: 
• posterior proximal
• anterior midway
• posterior distal

Design and Technology


Design and Technology

Sophisticated design
SYNERGY Hip System incorporates successful Smith & Nephew design features including unique neck geometry and dual progressive offsets.

• Standard and high offset designs
• Threaded driving platform with an elliptical slot
• Improved neck geometry
• Recommended head/neck ratio
• No unnecessary anteversion
• Optimized 12/14 taper


Superior range of motion
The circulotrapezoidal neck and optimized 12/14 taper designs of SYNERGY stems provide increased range of motion (ROM) compared to other designs.

Surgical simplicity
All of the stems in the SYNERGY system (cemented and cementless) use the same 2 trays of instrumentation. The simple ream-and-broach system provides operating room efficiency: ream to a 14, broach to a 14, implant a 14 stem.
• Locking broach handles
• Few trial necks required
• A variety of trial heads
• Rigid stem inserter
• Easy-to-use anteversion handle

Cementless Stems
The cementless line of SYNERGY stems is manufactured from a titanium alloy, Ti 6Al-4V

1. Porous
The sintered-bead ROUGHCOAT™ Porous Coating is manufactured from commercially
pure titanium

2. HA
SYNERGY HA is a press-fit stem with the proximal one-third sprayed with 50 microns of almost 100% pure HA over a grit-blasted surface.

3. Porous Plus HA
SYNERGY Porous Plus HA Cementless Stem uses the same technology as the SYNERGY Porous Stem. HA is applied to the porous coating using the same specifications as the HA stem.


Cemented Stems
SYNERGY Cemented Stem offers many of the advantages of the cementless system, along with special benefits due to its unique design. SYNERGY Cemented Stem is made of forged cobalt chrome with a satin surface finish. Features of the cemented stem include:

• Cement mantle
• Distal groove stability
• Ramp and collar pressurization
