Paragraph Number

49

Many spinal implants, implant systems, fixation devices, and/or assemblies include deployment of one or more fixation devices, such as bone anchors or bone screws, within a pedicle of the vertebra. Such fixation devices are referred to herein as pedicle screws. It is desirable that pedicle screws be deployed coaxial with a longitudinal axis of the pedicle. Unfortunately, pedicles within a single vertebra can have different sizes, diameters, and orientations relative to other landmarks of the vertebra. Furthermore, pedicles of different vertebra can have different sizes, diameters, and orientations relative to each other and relative to other vertebra.
