A drill guide system is provided for forming a hole along a desired trajectory in the bone of a surgical patient. The drill guide system comprises a drill bit defining a drill bit axis and a drill guide comprising a frame having a proximal arm and a distal arm fixedly spaced apart. The drill guide further comprises a first guide portion extending from the proximal arm and including a first channel defining a first guide axis, and a pointer projecting proximally from the distal arm and aligned with the first guide axis. The drill bit is transversely insertable into the first channel into an operational position in which the drill bit is constrained to translate only along the first guide axis.
