BonOs® R NF & BonOs® R NF Genta

BonOs® R NF and BonOs® R NF Genta are bone cements for use in artificial joint replacement.

BonOs® R NF and BonOs® R NF Genta are fast-setting acrylic bone cements 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.

Properties

The mechanical properties of BonOs® R NF and BonOs® R NF Genta guarantee reliable bone anchorage of the prosthesis.
The composition of BonOs® R NF and BonOs® R NF Genta is based on Charnley’s principles 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.

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.
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.

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.

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.

EASYMIX® uno

EASYMIX® uno mixing system is a sterile disposable vacuum mixing system for the secure mixing of bone cement.

The vacuum mixing and cementing technique reduces the porosity of the cement. Reduced porosity leads to a considerable increase of strength of the cement.

Properties

EASYMIX® uno is comfortable to handle. Just a few secure steps provide excellent mixing results. The use of EASYMIX® uno in combination with PMMA bone cements relies on established procedures in the operating room and on well-known and safe processes of mixing and application.

Mixing with the EASYMIX® uno vacuum mixing system reduces the porosity of the cement. Studies indicate that reduced cement porosity lowers the risk of subsequent revisions resulting from aseptic loosening. 1) 2)

The reduced porosity of the cement leads to an increase of the fatigue and bending strength of the cement. The usage of EASYMIX® uno vacuum mixing system improves the cementing results and therefore the stability of the connection of prosthesis and host bone.2)

EASYMIX® uno is suitable for retrograde filling.

Compositions

The EASYMIX® mixing system consists of the EASYMIX® vacuum pump, the EASYMIX® cement injector and the EASYMIX® uno cartridge sets.

C~plug®

C~plug® is a resorbable distal cement restrictor that seals the intramedullary cavity and improves cement grouting to the implant surface for better implant fixation.

A distal plug inhibits the cement penetration into cancellous bone and improves the cement’s molding into the implant surface.

Properties

The C~plug® resorbs within approximately four weeks and does not need to be removed in potential future revisions. Furthermore the C~plug® is distinguished by its increased contact surface, accurate positioning and reduced distal pressure.

Modern cementing techniques allow the creation of an optimal cement mantle within the femoral canal. Using the C~plug® reduces the risk of a revision.

BonOs® Inject

BonOs® Inject is a PMMA bone cement that is specifically adapted for spine surgery.

The cement is suitable for the fixation and filling of symptomatic vertebral compression fractures, vertebral tumors and vertebral hemangioma as well as for the augmentation of pedicle screws* where bone quality is poor, e.g. in patients with osteoporosis or degenerative or neoplastic changes.

Properties

BonOs® Inject is a radiopaque, injectable bone cement, characterized by its optimal combination of a short mixing period, a long working time and excellent mechanical properties.

During the mixing phase, the powder and liquid components of BonOs® Inject quickly mix together into a homogenous, ductile paste. After a short waiting period, the cement reaches an ideal viscosity for application. During the application phase BonOs® Inject is injected with a suitable viscosity which reduces the risk of cement leakage.

The unique cement formulation guarantees an optimized long application time, minimizing time pressure during application.

The viscosity of BonOs® Inject allows it to be used in combination with standard mixing and application systems for use of PMMA bone cements for spinal applications.

BonOs® Inject contains the radiopacifier zirconium dioxide (ZrO2), which allows a safe application and a good visibility of the bone cement under x-ray.

Vertebroplasty Accessories

For the application of the PMMA bone cement into the vertebral body during a vertebroplasty procedure several accessories are used e.g. injection systems/syringes. After mixing of the PMMA bone cement components the PMMA bone cement is transferred out of the mixing system into injection systems or syringes. After filling of the injection systems/syringes the PMMA bone cement is injected over cannulas into the vertebral body to be treated. The PMMA bone cement will be hard in just minutes – see handling chart of the PMMA bone cement.

Vertebroplasty is little stressful and elderly patients can be treated outpatient with local anesthesia. The treatment of several vertebral bodies is possible with one surgical procedure.

OSARTIS offers the following articles for use in vertebroplasty:

PerOssal®

PerOssal® is a synthetic, biodegradable and osteoconductive bone substitute material for restoration and filling of bone defects.

The unique microporous structure ensures uniform uptake of liquid substances (such as antibiotics) and their controlled sustained release [1].

The complete resorbability and simultaneous formation of new bone makes explantation of the material unnecessary [2, 3].

Nanocrystalline / porous

  • Promotes natural bone growth.
  • Suitable for increasing volume with autologous cancellous bone transplantation [4].
  • Suitable as carrier material for aqueous solutions (e.g. antibiotics [1, 5]).*

Custom loadable

  • Targeted highly effective antibiotic protection of the bone substitute material and the surrounding tissue according to the individual antibiogram with minimum systemic side effects.*

Protracted

  • Controlled long-term protection (10 days) from colonization of the bone replacement material with sensitive bacterial pathogens [6].*

*The use of the bone substitute PerOssal® as carrier for pharmaceuticals falls within the responsibility of the treating physician. The contraindications of the applied antibiotic have to be considered.
