1. A clamp device for use in a bone fixation procedure comprising:
a first arm including a handle at one end opposite a clamping end, and a first elongated slot in between the two ends of the first arm, the first elongated slot extends through the first arm in a direction of elongation and opens toward the clamping end of the first arm;
a second arm including a handle at one end opposite a clamping end, and a second elongated slot in between the two ends of the second arm, the second elongated slot extends through the second arm in a direction of elongation and opens toward the clamping end of the second arm;
a cannula block including a body portion having a channel extending through the body portion, a post extending from the body portion, and a cap at an end of the post; and
a rotary cannula including a body portion having a cannulation along the body portion's long axis, wherein the rotary cannula is configured to be positioned through the channel of the cannula block,
wherein each of the first arm, the second arm, the cannula block, and the rotary cannula are distinct, separate components that are configured to allow the clamp device to be repeatedly assembled and disassembled into the clamp device's distinct, separate components,
wherein in an operate configuration, the post of the cannula block is positioned within the first and second elongated slots, which allows the first and second arms to rotate about the post to move the clamping ends away from and towards each other to clamp a bone to maintain a position of the clamp device relative to the bone,
wherein the body portion of the cannula block includes a tab within the channel, wherein the body portion of the rotary cannula includes a flat surface and a groove extending around the rotary cannula' s body portion and terminating at the flat surface, and wherein the tab is configured to translate within the groove when rotating the rotary cannula within the cannula block,
wherein the cannula block and the rotary cannula are configured to allow the rotary cannula to only be axially translated through the channel of the cannula block when the tab is oriented with the flat surface, and
wherein the cannula block and the rotary cannula are configured such that the rotary cannula is locked to the cannula block, such that the rotary cannula is prevented from translating along the long axis of the rotary cannula' s body portion, upon rotating the rotary cannula so that the tab is positioned within the groove.
