Unique AVA Skull Pin Technology Benefits
significantly less slippage
In preclinical testing, the AVA Skull Pin Technology reduced slippage by 51% compared to standard skull pin systems.1
1Preclinical testing on mixed-gender cadaveric specimens, aged 63–102 years, showed for our novel pinning system 51% reduced slippage at 347 N (clinically relevant loads & procedures including simulated trepanation) and 35% reduced slippage at 520 N (1.5-fold safety margin above clinical loads).
Potential preservation of Navigational accuracy
In preclinical head phantom testing in bifrontal craniotomy, the AVA Skull Pin Technology reduced tracker displacement by 44% during loading compared to standard configurations, potentially preserving navigational accuracy in systems without continuous cranial position monitoring.
