“CarboJet lavage provides my patients with a much cleaner, drier bone bed allowing for better cement penetration and hence a better mechanical interface between bone and implant for secure long-term fixation.”

Cleaner is Better
Why Use CarboJet CO2 Compressed Gas Lavage to Clean Bone?
- Potential for Increased Cement Penetration Into the Bone Bed
- Reduced Opportunity for Micro-Emboli
A compressed CO2 gas jet is more effective at removing fluid and fluid-suspended debris from a porous matrix than a liquid cleaning jet. The liquid jet is useful for “washing” of gross debris, but is much less effective at removing fluid debris in the interstices of cancellous bone. The fluid jet works in a porous structure by incremental mixing, dilution and displacement. The compressed gas jet accomplishes fluid- debris removal by creating strong, fluctuating pressure gradients, displacing debris rapidly and more thoroughly. |

| Saline lavage is effective at removing gross debris, but fluid mixing in the interstices of bone prevents thorough cleaning. |

A compressed gas jet effectively displaces fluid and fluid- suspended debris, thereby cleaning and drying porous structures. |

The CarboJet CO2 Lavage System, in clinical use since 1993, has been used safely on thousands of joint replacement patients. Compressed CO2 gas has been employed as an insufflation medium in laprascopic procedures for many years and is readily available at all hospitals.
“I have made gas jet lavage with CarboJet the critical last step in bone preparation in all my cemented arthroplasty cases. The removal of additional marrow elements that could otherwise form embolic debris during cement pressurization is important to patient safety.”
