Key Points

This study aims to evaluate how articulated rotary burs (ARBs) can improve access for bone resection procedures.
Conducted geometric modeling to assess the effect of distal articulation on cross-sectional area (CSA) in various positions.
Examined the implications for minimally invasive surgical techniques.
The ARB demonstrated a 601% increase in cross-sectional area (CSA) in articulated positions.
Improvements in geometric access suggest potential benefits for surgical settings, but further validation is needed.

Abstract

). Overall, the ARB demonstrated a 601% greater CSA.ConclusionIn this geometric modeling study, distal articulation increased accessible CSA across articulated positions. ARBs may expand geometric access in minimally invasive settings; however, translation to surgical performance (eg, resection rate, thermal effects, torque transmission, and safety) requires empirical validation.
