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. 

Features and Benefits

The SYNERGY Hip System provides you a complete range of options to match your patients’ needs. The implants include solutions for: 

  • Cementless,
  • Cemented
  • Fracture management cases-CONQUEST FX

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: 

  • posterior proximal
  • anterior midway
  • posterior distal

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.

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

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:

  • Osteoarthritis
  • Avascular necrosis
  • Traumatic arthritis
  • Slipped capital epiphysis
  • Fused hip
  • Fracture of the pelvis
  • Diastrophic variant

Hip components are also indicated for inflammatory degenerative joint disease including:

  • Rheumatoid arthritis
  • Arthritis secondary to a variety of diseases and anomalies, and congenital dysplasia
  • Old, remote osteomyelitis with an extended drainage-free period, in which case, the patient should be warned of an above normal danger of infection postoperatively
  • Treatments of nonunion, femoral neck fracture and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques
  • Endoprosthesis
  • Femoral osteotomy, or Girdlestone resection; fracture-dislocation of the hip
  • Correction of deformity

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.
