Arcos® Modular Femoral Revision System

1000x1000_insetimage_Hips_Arcos

Zimmer Biomet’s Arcos® Modular Femoral Revision System meets the demands of complex hip revision surgery by offering surgeons and OR staff the ability to customise both the hip implant and its corresponding instruments. Three proximal and 5 distal geometry options provide surgeons 117 proximal/distal combinations and multiple auxiliary fixation options for various femoral defects. This allows surgeons and OR staff the surgical control, customisation options, and reproducibility to efficiently address both patient and practice needs.

The features of the Arcos Modular Femoral Revision System include:

  • Three proximal body options:
    • Cone
    • Broach
    • Calcar
  • Five distal stem options:
    • STSTM (Splined Tapered Stem)
    • Slotted
    • Bullet-tip
    • Interlocking
    • ETO (Extended Trochanteric Osteotomy)
  • Multiple surgical technique options
    • Ream-over
    • Sterile field
    • In-femur
  • 1 simple, easy to use instrumentation platform
  • Standard and high offset options reproduce various patient anatomies without lengthening the leg
  • Consistent sizing (1mm increments) for increased OR efficiency and accurate matching of the patient’s femur
  • Roller-hardened taper junction technology for greater fatigue strength and 3 times more strength in cantilever beam testing than non-roller hardened tapers1
  • PPS® coating allows for initial scratch-fit stability and biologic fixation2-9
  • Flexibility of titanium allows for stress transfer to preserve cortical density10

Product Features

Providing Options for Intra-operative Flexibility

In femoral revisions, it is necessary to address metaphyseal and diaphyseal deficiencies independently. With 3 proximal bodies and five distal stems, which all work together regardless of size, a surgeon is able to address deficiencies in both regions of the femur independent of each other. This compatibility allows for a surgeon to change stems intra-operatively if encountered with something different from their pre-operative planning. The availability of standard and high offset proximal body offerings are additional tools that allow the surgeon intra-operative flexibility to address patient needs as they arise.

 

Bolt and Claw Auxiliary Option

The Arcos Modular Femoral Revision System has the ability to use auxiliary implants to reattach the trochanteric fragment directly to the implant. By reattaching the trochanteric fragment in this fashion, the soft tissue and bony fragment are stabilised and provide an additional level of stability.

 

Streamlined Instrumentation

Designed with common proximal implant and instrument geometries, the Arcos Platform design allows for intra-operative revision efficiency by reducing the number of instrument cases required to a number comparable to a primary hip surgery.

Technology

  • PPS® Porous Plasma Spray

Instrumentation should not limit surgeons’ implant selection or preferred surgical technique. Zimmer Biomet’s Arcos® Modular Femoral Revision System is designed to provide the option to use any implant combination with the surgical technique that is required to address each patient’s needs.

Designed with common proximal implant and instrument geometries, the Arcos platform design allows for intraoperative revision efficiency by reducing the number of instrument cases required to a number comparable to a primary hip surgery.
