Abstract
An orthopedic driver is provided that includes an elongate tubular body and an indicator assembly. The indicator assembly has a housing that has at least one opening and a visual indicator disposed in the at least one opening. The visual indicator is configured to be coupled with a guide pin such that lateral movement of the elongate tubular body relative to the guide pin causes the visual indicator to move between a flush or recessed configuration within the housing and an extended configuration. In the extended configuration, the visual indicator extends outward of an outer surface of the housing. The flush or recessed configuration corresponds to alignment of the guide pin relative to the elongate tubular body and the extended configuration corresponds to misalignment of the guide pin relative to the elongate tubular body.
