Abstract
Multi-directional drilling of a bone to create a perforation of bone cortex. The disclosure presents methods of using a drill having a measurement system to advance a drill bit through a bone with detection of penetration or eruption of the leading edge of the drill bit through the exterior of the cortex layer of the bone. In this regard, operation of the drill may be controlled to limit soft tissue damage adjacent to the distal side of the bone. The drill bit may be at least partially retracted through a first bore, repositioned, and one or more additional bores may be created, all while monitoring for penetration of the leading edge of the drill bit relative to the cortical layer. In turn, a perforated distal side of the cortical layer of the bone may be created that creates a desired weakness in the bone, which may be useful in various operations including when performing a corticotomy or the like.
