The use of Chronos is an advantageous alternative to bone harvesting.
It shortens operative time, overcomes the limitations in quantity and quality of available bone graft and avoids donor site morbidity.
Chronos is a synthetic cancellous bone graft substitute, which remodels into bone, is easy to use and has a clinical track record of twenty years.
Its synthetic origin provides unsurpassed safety.
Chronos consists of pure beta-tricalcium phosphate and has an excellent in vivo behavior.
Its strength is similar to that of cancellous bone, and its scaffold provides an ideal structure for osteoconductivity.
It is gradually resorbed and replaced by new bone, this remodelling process takes 6-18 months.
Chronos can be used in all spinal applications instead of cancellous bone graft: postero-lateral fusion, interbody fusion (as cage filling material), vertebrectomies (as filling material for vertebral implants).
Chronos has also indications for trauma and cranio-maxillofacial surgery.
