Features & Benefits

chronOS® Bone Graft Substitute contains calcium and phosphorus, two of the main mineral constituents of bone. During the healing process, it is resorbed and replaced by bone between 6 – 18 months.

chronOS® Bone Graft Substitute

  • Available as granules and preformed shapes
  • Provides the ideal pore size (100 – 500 µm) and porosity (60 – 70%) for bony ingrowth
  • Can be perfused with the patient’s own blood or bone marrow
  • Can be used alone or mixed with autograft for large volume defects
  • Fully synthetic – no risk of disease transmission
  • Reduces operation time and morbidity associated with iliac crest harvests, which may lead to a shorter hospital stay and therapy
