Abstract: In one aspect, wireless strain gauges are described herein. In some embodiments, a wireless strain gauge comprises a radio frequency identification (RFID) tag and a nano-composite backplane coupled to the RFID tag, wherein the resonant frequency of the RFID tag antenna demonstrates an exponential dependence or substantially exponential dependence on the strain sensed by the strain gauge.

Abstract: This patent describes a device to replace the proximal femoral head and neck. The uniqueness of the device is in its proximal design which incorporates a transverse tension bar which prevents failure of the femoral neck portion of the device in tension. This design characteristic permits the use of thinner materials which more closely resemble the elastic nature of bone itself while at the same time endowing the prosthesis with strength and resistance to failure. The device is designed to have a long intramedullary portion which would load the femur throughout its length as well as a modular attachment on its distal end for the insertion of a future knee replacement.

Abstract: A pelvic fixation device which allows the three dimensional reduction of pelvic fractures, dislocations, or fracture dislocations. The device is adapted to attach to the anterior aspect of each hemipelvis. On one side it is devised to fixate the hemipelvis while on the other side it is adapted to provide a mechanism for distraction or compression and maintenance of this manipulative reduction force in three dimensions, especially in an anterior/posterior or vertical/inferior direction for a prolonged period of time. The device is adapted to be portable by its inclusion of a frame which can be placed beneath the patient or it can be applied in an operating room or emergency room and used as definitive or adjunctive treatment to other surgical procedures on the pelvic bone.
