A device includes a first arm and a second arm. The first arm includes a first arm body that extends from a first end to a second end and a guide. The guide is rotatably coupled to the second end of the first arm body and is configured to be coupled to a first bone. The second arm includes a second arm body extending from a first end to a second end and is coupled to the first arm body such that it is rotatable with respect to the first arm body. The second arm is configured to engage a second bone. In use, rotation of the second arm body with respect to the first arm body changes the distance between the first bone and the second bone and rotation of the guide with respect to the first arm body rotates the first bone.

An off-the-shelf oral splint that is operatively secured to the maxilla and mandible to assist in reduction and provide maintenance of reduction of maxillary and mandibular fractures in the edentulous or partially edentulous patient. The oral splint is fabricated into a plurality of standardized sizes. These sizes are determined by imaging a population of jaws, measuring dimensions thereof, manipulating (e.g., calculating the mean) these dimensions, and generating a size that is representative of a subset of that population. This can be done for all sizes that would represent individuals in that population. The splint itself is fabricated virtually by creating “U-shapes”, splitting them horizontally into halves, creating an evacuation channel, and generating a coupling mechanism to hold the halves together. The splint can then be printed or otherwise manufactured.

Various implementations include an external fixation device for posterior pelvic compression that allows a pin engaged into one iliac bone to be pivoted relative to the pin engaged into the other iliac bone, allowing compression of the iliac bones toward each other and the interposed sacrum and for the relative positions of the pins to be held fixed relative to each other after the compression is set. The pin to be pivoted is engaged into the iliac bone closest to the source of the injury. And, the pins and bars of the fixation device are anteriorly coupled together, which gives the patient greater transportability, as well as maintenance of reduction that will assist in the definitive surgical intervention.

A system for evaluating the evolution of a subject's bone structure, including an implantable medical device and a calculation module for computing a parameter representative of the bone structure. The implantable medical device has a distraction body and reflector(s). The distraction body distracts osteotomically separated bone section bodies and includes first/second blocks for implantation and attachment to first/second bone sections, the second bone section separated from the first bone section by an osteotomy, and an actuator for adjusting space between the first/second blocks, enabling distraction between the first/second bone sections. Each reflector reflects an electromagnetic signal and is embedded in a surrounding tissue when the distraction body is attached to the bone. The parameter is computed from the reflected signal, of an excitation signal including a frequency in the characteristic frequency range of each reflector, the reflected signal being representative of a dielectric constant of the surrounding tissue.

An extracorporeal bone compressing link and apparatus and method using same. Active devices that incorporate the extracorporeal bone compressing link can transport and compress bone through external means by acting on conventional bone fasteners including but not limited pins or wires that penetrate through the skin and fixate into bone.

An orthopedic bone tap is provided, including a rod comprising a proximal end, a medial portion, and a distal end. The orthopedic bone tap also includes a plurality of cutting threads on the distal end of the rod. The orthopedic bone tap also includes an axial compression member engaged with at least one of the proximal end and the medial portion of the rod. The axial compression member is adapted and configured to exert compression that draws a bone fragment engaged with the plurality of cutting threads distally and against another bone fragment.

An anatomical gripping system comprising: a binding comprising: a substantially rigid spine; a calf shell mounted to the substantially rigid spine; an anterior shell; and a clamping mechanism connecting the anterior shell to the calf shell; wherein the calf shell comprises a flexible portion configured to selectively engage the superior portion of the calcaneus bone of a patient; and further wherein when the clamping mechanism applies a force to the flexible portion of the calf shell, the flexible portion of the calf shell is drawn into engagement with the superior portion of the calcaneus bone of the patient.
