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 provides you a complete range of options to match your patients’ needs. The implants include solutions for:
Each of these options uses the same surgical technique and the same two trays of surgical instruments.
The SYNERGY Hip System gets initial stability through three-point fixation:
This fixation is demonstrated in the X-ray.
Synergy is a bonded system approach and can be used with or without cement. This versatile system allows you to use one set of instrumentation.
99.5% Survivorship after 10 years!!!!!

SYNERGY Hip System incorporates successful Smith & Nephew design features including unique neck geometry and dual progressive offsets.
The circulotrapezoidal neck and optimized 12/14 taper designs of SYNERGY stems provide increased range of motion (ROM) compared to other designs.
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.
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.
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:
The stem shape is based on the SPECTRON stem, which has a 20-year record of clinical success.

Hip components are indicated for individuals undergoing primary and revision surgery where other treatments or devices have failed in rehabilitating hips damaged as a result of trauma or noninflammatory degenerative joint disease (NIDJD) or any of its composite diagnoses of:
Hip components are also indicated for inflammatory degenerative joint disease including:
Both cemented and cementless femoral components have demonstrated long-term durability in the treatment of severe arthritic conditions of the hip. An algorithm has been developed that helps define which implant matches each patient’s needs. The algorithm takes into consideration patient age, bone stock, disease type and implant cost.
