“The team also prespecified an exploratory tissue-concentration benchmark of 16 micrograms per gram, numerically four times the epidemiological cutoff value of 4 micrograms per milliliter for Staphylococcus aureus in the EUCAST database. Because the reference value is a fluid concentration while tissue measurements are expressed per gram of tissue, the researchers stressed that the benchmark should be regarded as an”

Compared with intravenous administration, the 750 milligram intraosseous regimen produced fat concentrations 9 to 13 times higher, synovial concentrations 4 to 8 times higher, and bone concentrations 9 to 41 times higher, with the 1,500 milligram intraosseous dose producing even higher tissue levels.

- Surgical robotics — News discoverySignalIntraosseous Cefuroxime Outperforms IV Dosing in Robotic Knee Surgery Trial
A randomized controlled trial found that injecting cefuroxime directly into bone before robotic-assisted total knee replacement results in significantly higher tissue concentrations of the antibiotic compared to intravenous administration. The study, published in Arthroplasty, showed that a 750 mg intraosseous dose achieved nearly as high tissue concentrations as a 1,500 mg dose while maintaining lower systemic levels. The results suggest that intraosseous administration may be more effective for prophylactic antibiotic delivery in robotic knee surgery.
