1. A system for mounting a retractor tube comprising:
- an awl including an elongate body that extends between proximal and distal ends, the proximal end supporting a handle, the distal end having a bone engaging tip adapted to secure the awl to a vertebral body;
a first dilator having proximal and distal ends, the first dilator defining a longitudinal axis that extends between the proximal and distal ends of the first dilator, and a first longitudinal bore that extends through the first dilator, the first longitudinal bore adapted to receive the awl;
a retractor tube having a tubular body that extends between proximal and distal ends, the tubular body having an inner surface and an outer surface, the inner surface defining a second longitudinal bore that extends through the tubular body, the outer surface defining a plurality of channels; and
a plurality of pins adapted to be received within the plurality of channels of the retractor tube to enable the plurality of pins to secure the retractor tube to a vertebral body, the plurality of pins configured to anchor in a vertebral body.

Abstract
A system for mounting a retractor tube to a spine without a guidewire is disclosed. The system includes an awl, a first dilator configured to be advanced over the awl, a retractor tube configured to be advanced over the first dilator, wherein an outer surface of the retractor tube defines a plurality of channels, and a plurality of pins adapted to be received within the plurality of channels, wherein the plurality of pins secure the retractor tube to the at least one vertebral body of the spine. A method for selectively mounting a retractor tube to a spine without a guidewire is also disclosed.

13. A system for mounting a retractor tube comprising:
-
an awl including an elongate body that extends between proximal and distal ends, the proximal end supporting a handle, the distal end having a bone engaging tip adapted to secure the awl to bone; a first dilator having proximal and distal ends, the first dilator defining a longitudinal axis that extends between the proximal and distal ends of the first dilator, and a first longitudinal bore that extends through the first dilator, the first longitudinal bore adapted to receive the awl; a retractor tube having a tubular body that extends between proximal and distal ends, the tubular body having an inner surface and an outer surface, the inner surface defining a second longitudinal bore that extends through the tubular body, the outer surface defining a channel; and a pin adapted to be received within the channel of the retractor tube to enable the pin to secure the retractor tube to bone, the pin defining a shank extending between a head at aroximal portion thereof and a threaded distal portion configured to threadably engage bone.
