Embodiment Construction

[0052] The following description will explain the embodiments of the invention, beginning with a device used for treating deteriorating or damaged bones in the medial column of a human foot, and concluding with the method for treating deteriorating or damaged bones in the medial column of a human foot. Both the first and second figures are skeletal outlines of a human foot, depicting the device therein and the resulting orientation of the bones by using the method specified below.

[0053]FIG. 1 is a top down view of a right human foot, depicting the bones therein and an implant or intramedullary nail 10 running through the mid-foot region. The implant or intramedullary nail 10 runs through the medullary canal of first metatarsal 7, medial cuneiform 3, navicular 2, and talus bone 1. The talus bone 1 makes up the lower part of the ankle joint where the proximal end 11 of the implant or intramedullary nail 10 is attached with at least one fastener (or locking screw, with two depicted in...
