Abstract: Systems, methods, and devices for transverse bone transport. A transverse bone transport system may include a template for measuring and cutting a segment of the bone and a distractor for moving the segment. The template may include a plate including an opening configured to fit a pin sleeve. A channel may extend from the opening in the plate to a side of the plate. The distractor may include a first beam, a second beam, and an actuator including a knob configured to rotate in a first direction to increase a distance between the first beam and the second beam and in a second direction to decrease a distance between the first beam and the second beam.

Abstract: The present disclosure relates to a programmable wrench for automatically adjusting the length of external fixation struts, the programmable wrench comprising: a mechanical connector meant to releasably engage with the external fixation strut thus enabling transmission of at least an adjustment torque from the programmable wrench to the external fixation strut; and an electrical connector meant to releasably connect with the external fixation thus enabling at least a data transmission from the external fixation strut to the programmable wrench. The mechanical connector and the electrical connector may be integrated in a common port and may be jointly engaged and disengaged with the external fixation strut.

Abstract: A tool for adjusting an external fixation strut includes a first connecting portion adapted to perform data communication with the external fixation strut via a connecting portion, and a controller which includes command instructions. Based on the command instructions, the controller is configured to download prescription data including instructions for performing an adjustment of the external fixation strut of the patient, after the tool has been coupled with the external fixation strut, recognize a coupling state with the external fixation strut. Once the coupling is complete and data with the external fixation strut have been exchanged, wait for a date and/or time in which the prescribed adjustment is to be applied based on the prescription data. A related external fixation strut and a related medical assembly are also disclosed.

Abstract: The present disclosure relates to an external fixation strut that includes an elongated body comprising at least a first shaft and a second shaft moveable with respect to each other to modify the length of said elongated body, and a sensor integrated in the external fixation strut and adapted to perform at least a measurement which is indicative of the length of the elongated body. The sensor may communicate with a programmable tool for lengthening/shortening the external fixation strut through a data port which is engageable by said programmable tool.

Abstract: A programmable tool operable to adjust an external fixation strut includes an output shaft, a motor operable to rotate said output shaft, aa first coupling portion solidly attached to said output shaft and adapted to releasably engage with a corresponding second coupling portion of the rotatable adjustment mechanism, thus enabling torque transmission from the motor to the rotatable adjustment mechanism; a controller configured for driving said motor according to a prescription comprising instructions for adjusting the external fixation strut; and a first connecting portion in electrical communication with said controller and adapted to electrically connect with a second connecting portion of the rotatable adjustment mechanism when the first coupling portion is engaged with the second coupling portion, thus enabling data transmission from the external fixation strut to the controller.

Abstract: A 3-D model of a body part is created by using an object comprising markers, fixation members, and struts. The method involves first and second roentgenograms of the body part and the object disposed between an x-ray source and an x-ray imager. It then determines first and second sets of distances between projections of the markers or the struts, and determines first and second 3-D positions of the x-ray source and of the object with respect to the x-ray imager using predetermined distances between the markers or struts and the first and second sets of distances between their projections. The method then aligns the first and second 3-D object projections in a 3-D reference frame using the 3-D positions of the markers or struts with respect to the x-ray imager in the two orientations. The method creates the 3-D model of the object based on the 3-D object projections.

Abstract: Modeling an object in 3-D space may be accomplished various embodiments disclosed herein. An exemplary method of creating a 3-D model includes receiving roentgenograms of an object and at least one reference marker. In some embodiments, the roentgenograms may each include an image of at least one object marker. The exemplary method may further include determining 3-D positions of the x-ray source using the images of the at least one reference marker. The location of the 3-D positions of the x-ray source may allow a 3-D model of the imaged object to be created.
