PALAMIX® cartridge vacuum mixing system for bone cement

Using modern cementing technique in arthroplasty is key to ensure long survival rates for endoprostheses and a low risk of revision.1, 2 One of its crucial success factors is a homogeneously mixed bone cement.3

Vacuum mixing improves bone cement homogeneity by reducing porosity and strengthens the bone cement prosthesis interface.4

Advantages of PALAMIX® at a glance:

PALAMIX cartridge vacuum mixing system for bone cement

  • various application options for flexibility in surgery
  • safety for staff and patients

Safety for Staff and Patients

PALAMIX filling funnel including a particle filter and PALAMIX vacuum hose with active charchoal filter

To ensure a high level of safety, PALAMIX® has a filling funnel with two separate sections for the bone cement components. A particle filter in the liquid chamber protects against small glass particles in the bone cement. It avoids injuries and preserves the cement’s mechanical quality.
Additionally, the PALAMIX® vacuum hose comes with an active charcoal filter that minimises Methyl Methacrylate fumes during mixing.5

Mixing and Collecting

PALAMIX - Mixing of componentes and collection of the bone cement is carried out under vacuum

With PALAMIX® the mixing of the components and the collection of the bone cement is carried out under vacuum. This not only facilitates mixing and saves preparation time before application, but also reduces porosity. 6

Applying and Pressurising

PALAMIX® provides various options for application and pressurisation of bone cement. Different nozzles are available for individual procedures and allow flexibility in surgery. With PALAMIX®, it is even possible to expel the mixed bone cement remaining in the nozzle, thereby minimising cement waste.

Pressurisation results in greater penetration of the bone, improved bone cement interface and increased fatigue strength of the cement.7
