BonOs® R NF & BonOs® R NF Genta

BonOs® R NF is a fast-setting acrylic resin for use in bone surgery.

BonOs® R NF Genta contains the antibiotic gentamicin sulfate that protects the implant and the surrounding tissue from colonization with pathogens that are sensitive to gentamicin. BonOs® R NF and BonOs® R NF Genta cement powders contain insoluble zirconium dioxide as X-ray contrast medium.

Description

Properties
  • High viscosity bone cements for cemented joint arthroplasty
  • Long working and fast setting time
  • Ideal for vacuum and hand mixing
  • Prechilling for additional working time possible
  • Reliable prosthesis fixation and high fatigue strength
  • Contains zirconium dioxide for X-ray contrast
  • Controlled release of the antibiotic
Optimal Monitoring of Results

Zirconium dioxide is added to BonOs® R NF and BonOs® R NF Genta to guarantee optimal X-ray visualization. The surgeon can at any time assess the distribution of the cement in the bone and around the implant on the X-ray image and thus assure an optimal outcome of the procedure.

Composition

The composition of BonOs® R NF and BonOs® R NF Genta is based on Charnley’s principle of using PMMA bone cements in artificial joint replacements, which was established as the gold standard 50 years ago. In accordance with Charnley’s principles, OSARTIS bone cements contain only the necessary raw materials.

Well-established Processes in the Operating Room

BonOs® R NF and BonOs® R NF Genta rely on established procedures in the operating room and on well-known and safe processes of mixing and application. After mixing, only a short waiting time is required before the highly viscous cement is no longer sticky. Application can start immediately after this short waiting period.

Depending on the user’s needs, the cement can be mixed by hand or in a vacuum mixing system. Vacuum mixing can be done with pre-chilled bone cement.

At 21°C the surgeon has a comfortable 6 minutes after mixing by hand or 4.5 minutes after using a vacuum mixing system to introduce the cement into the bone and position the implant. The application time can be prolonged by prechilling the cement.

Reliable Bone Fixation

The mechanical properties of BonOs® R NF and BonOs® R NF Genta guarantee reliable bone anchorage of the prosthesis.

Reproducible Release of the Antibiotic

BonOs® R NF Genta contains the established antibiotic gentamicin sulfate.

The local application of gentamicin is gentle on the patient.

BonOs® R NF Genta releases the established antibiotic gentamicin in a proven way, over a prolonged period and in effective, reproducible concentrations.
