1. A percutaneous targeting device comprising:
a body that is arc-shaped;
an extension including a first attachment hole and an attachment opening, the attachment opening including a second attachment hole and a third attachment hole, wherein no sidewalls are located between the second attachment hole and the third attachment hole, wherein the extension is moveable relative to the body, and a position of the extension is adjustable relative to the body to change an angle between a target pin and a first guide wire;
a targeting assembly including a target sleeve defining a target channel, the targeting assembly including a hook of a hook assembly that is configured to be inserted intramedullary into a proximal bone part of a metatarsal bone, and the metatarsal bone is split into the proximal bone part and a distal bone part;
the target pin receivable through the body and configured to be placed in the distal bone part of the metatarsal bone to reposition the distal bone part of the metatarsal bone, wherein the target pin is received through the target channel of the target sleeve of the targeting assembly,
wherein the first attachment hole is most distal to the target pin, and the attachment opening is proximal to the target pin,
wherein the targeting assembly is configured to hold the target pin in a fixed position relative to the targeting assembly, and
wherein the target sleeve is configured to allow for movement of the target pin within the targeting assembly;
the first guide wire inserted through the first attachment hole and configured to be inserted into the metatarsal bone;
a first cannulated fixation screw configured to be screwed into the metatarsal bone using the first guide wire;
a second guide wire inserted through one of the second attachment hole and the third attachment hole of the attachment opening depending on a desired distance between the first guide wire and the second guide wire; and
a second cannulated fixation screw configured to be screwed into the metatarsal bone using the second guide wire.
