Abstract: A subtalar arthroereisis screw may have a head and a body with a distal tip, a shank extending from the head to the distal tip, and a screw thread extending along the shank. The shank may have a leading end proximate the distal tip and a trailing end proximate the head. The screw thread may be continuously variable between a first pitch relatively closer to the trailing end, and a second pitch, larger than the first pitch, relatively closer to the leading end. The head may have a receiving end that is connectable to a tool to facilitate rotation of the head with the tool during implantation of the subtalar arthroereisis screw. The screw thread may taper continuously from a first major diameter at the trailing end, to a second major diameter, smaller than the first major diameter, and may have a plurality of notches distributed along its length.

Abstract: An apparatus and method for external anteversion correction of an intact bone may include a first arcuate segment, a second arcuate segment rotatably coupled to the first arcuate segment, a first pin extending from the first arcuate segment to a proximal segment of the intact bone, a second pin extending from the second arcuate segment to a distal segment of the intact bone, and a control mechanism attached to the first and second arcuate segments. The control mechanism may rotate the first arcuate segment relative to the second arcuate segment to exert torsional force on the intact bone between the proximal and distal segments of the intact bone, thereby externally reducing anteversion of the intact bone.

Abstract: A communication method for hearing impaired communication comprising: providing a speech training device to a hearing impaired user, the speech training device configured to teach the hearing impaired user how to determine non-speech sounds. The method further includes providing a haptic output device to a hearing impaired user where the haptic output device is configured to be relasably coupled to the hearing impaired user. The haptic output device receives, a sound input signal comprising a non-speech sound and provides the haptic output signal to an actuator which is in electrical communication with the haptic output device. The actuator actuates in response to the haptic output signal and provides a haptic sensation to the hearing impaired user.

Abstract: A communication method includes providing a speech training device configured to teach a hearing impaired user how to understand spoken language. The method further includes providing a haptic output device to a hearing impaired user, the haptic output device coupled to the hearing impaired user. The haptic output device receives a speech input from a non-hearing impaired person, the speech input directed to the hearing impaired user, and the haptic output device provides a haptic sensation to the hearing impaired user. The communication method also teaches a hearing-impaired person how to speak, and can teach a non-hearing impaired user to speak a foreign language. The communication method includes comparing speech of a user to a model speech, providing feedback to the user regarding the comparison, and repeating until the speech of the user matches the model speech.
