Bone fixation system and device

A method, comprising:

• forming a minimally invasive incision dorsal to a joint of a digit;
• inserting a preparation tool into the incision toward the joint until a flange member of the preparation tool abuts a surface of tissue proximate the joint;
• preparing bone surfaces at the joint with a cutting element of the preparation tool, the preparation tool including a shaft extending proximally relative to the flange member;
• removing the preparation tool;
• drilling a target hole in a first bone segment at the joint with a drill;
• positioning a first positioning element of a surgical instrument such that a second positioning element is aligned with a tip of the digit;
• adjusting the first positioning element;
• inserting a k-wire through a channel of the second positioning element, the tissue positioned between the first positioning element and the second positioning element, and a channel in the first positioning element;
• and
• implanting a bone anchor over the K-wire until a distal end of the bone anchor engages the bone, wherein the bone anchor is cannulated such that the bone anchor slides over the K-wire.

• drilling a target hole in a first bone segment at the joint with a drill;
• implanting a first bone anchor in the target hole until a head of the first bone anchor is positioned at a surface of the first bone segment and a shaft of the first bone anchor is anchored inside the first bone segment;
• placing a first positioning element at least partially around a skin surface of the digit;
• adjusting the first positioning element until alignment of a second positioning element of the surgical tool and the first bone anchor is attained;
• inserting a k-wire through a channel of the second positioning element, the tissue positioned between the first positioning element and the second positioning element, and a channel in the first positioning element;
• and
• implanting a second bone anchor over the K-wire until a distal end of the second bone anchor engages with at least the head of the first bone anchor, wherein the second bone anchor is cannulated such that the second bone anchor slides over the K-wire.
