Abstract: The present invention provides a subtalar implant as well as methods of use thereof for the purpose of correcting podiatric disorders such as various types of flat foot conditions relating to the subtalar joint. The subtalar implant is capable of threaded engagement with a positioning element used to position and manipulate the implant during surgical implantation in the sinus tarsi of the foot. The implant is cannulated to receive a guide rod to facilitate final positioning of the implant. Once implanted, the subtalar implant provides anatomical fit with the subtalar joint anatomical structure without the need for indentations to receive osseous tissue growth to anchor the subtalar implant.

Abstract: The present invention provides a cannulated hemi-implant with a base and a threaded stem for fixing the stem of the implant within a medullary canal of a phalanx or other bone in the foot. The implant includes a tri-part head capable of both cutting bone and self-threading, with bone forming the medullary canal of a phalanx of a human foot. The present invention also provides a hand tool which engages and rotates the implant within the medullary canal of the phalanx. The present invention further provides a method of surgically implanting the implant in the medullary canal of the phalanx or other bone.
