From its release in 2008, ACTIFUSE Bone Graft Substitute set a new standard for improved bone healing. Backed by 10 years of clinical experience and level 2 clinical evidence showing successful bone fusion results at 12 months.1,2

Accelerated Bone Growth

The unique ACTIFUSE formula has the ideal silicon content demonstrated to be optimal for bone formation in an animal model.3* With 80% porosity designed to mimic cancellous bone, ACTIFUSE is osteoconductive, osteostimulative, and provides accelerated bone growth.4,5

*Preclinical data. Results may not correlate to performance in humans.

Additional Product Benefits

Innovative Delivery and Ease-of-Use

ACTIFUSE bone graft substitute offers accelerated bone growth in many ready-to-use, prepackaged delivery options. ACTIFUSE is designed for precise placement into small bony voids through open and less invasive approaches.6

Solutions for Minimally Invasive Surgery

ACTIFUSE MIS provides for controlled delivery of ACTIFUSE Bone Graft Substitute in minimally invasive procedures in spine and general orthopedic applications.6

Distinctive and Versatile Handling

ACTIFUSE ABX and ACTIFUSE Shape support the surgeon’s technique by allowing for precise handling and implantation.2,7


  • Bone graft substitutes are intended to be used in place of corticocancellous, or cancellous allograft or autograft bone.
  • The mechanical environment for such uses experience either low load requirements or compression.
  • Typical surgical applications for bone graft substitutes are: Small void filling, e.g. after removal of a small bone tumour or following bone fracture reduction or in osteotomies.
  • Spinal fusion, where a cage or screw fixation device is used to relieve the graft site from physiological loads.
  • It is not intended to be used in place of cortical strut allograft bone where high tensile, torsion and/or bending strength are required. The products are used by surgeons in place of allograft bone (bone from humans stored in bone banks).

Risks and Warnings

  • The risks with ACTIFUSE (e.g., infection, graft loosening, nonunion, delayed union, repeat surgery) are the same as those for allograft bone. However, with ACTIFUSE there is no risk of disease transmission.
  • ACTIFUSE should not be used where it could be subject to tension, torsion, compression, shear, or bending. A conventional implant (e.g., screw, rod) can protect the graft from such loading actions.
  • ACTIFUSE should not be used in volumetrically unconstrained sites (so the graft material cannot move or escape).
  • Do not overfill or attempt to pressurize the bony defect site, as this may lead to extrusion of the product beyond the site of its intended application and damage to the surrounding tissues or may lead to fat embolization or embolization of the product into the blood stream.
  • Additional mixing containers and stirrers must be sterilized before use.
  • ACTIFUSE should be used with caution in pediatric cases harboring large juvenile bone cysts. Isolated cases of transient postoperative fever and inflammatory reaction, in the absence of infection, have been reported from clinical experience with extremely large cysts. This side effect had no negative impact on the therapeutic outcome.
  • The safety and effectiveness of the ACTIFUSE bone graft substitutes has not been studied in children under 8 and thus is not known.


  • Impaction grafting for failed total hip or knee arthroplasty.
  • Direct loading of graft material, i.e. in the absence of conventional implants, such as screws and rods.
  • Infection.
  • Inability to cover or deliberate non-coverage of graft site using soft tissue.
  • Avascular or compromised vascular network sites.
  • Patient metabolism may compromise bony regeneration.
  • Avoid use in patients where in the surgeon’s opinion patient lifestyle, compliance and/or physical attributes would compromise clinical outcome.
  • Medication which could slow bone healing.
