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: 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: 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 walking simulator includes: a lower-limb prosthetic device having at least a foot portion, a tibial element, and an ankle articular center suitable to connect the foot portion to the tibial element; a base structure, an arm coupled to the base structure via a coupler that allows the arm to rotate or pivot about a substantially horizontal axis of rotation, wherein the arm includes a fastener for constraining the prosthetic device to the arm so that it extends substantially parallel to the arm; a substantially horizontal base positioned under the prosthetic device, wherein the base includes a top portion suitable to receive in abutment a sole of the foot portion of the prosthetic device; a first actuator associated with the arm for creating a pivoting or oscillating rotary motion of the arm about the axis of rotation and for controlling the leg angle of the prosthetic device constrained to the arm.

Abstract: A prosthetic ankle-foot device, in particular of the biomimetic type, includes: a tibia element; a talus element movably connected to the tibia element through a first talocrural joint having a first hinge joint; a calcaneus element movably connected to the talus element through a second subtalar joint having a second hinge joint; a medial metatarsal element movably connected to the calcaneus element through a third medial midtarsal joint, the third joint having a third hinge joint; a lateral metatarsal element movably connected to the calcaneus element through a fourth lateral midtarsal joint, the fourth joint having a fourth hinge joint; a medial phalanx element movably connected to the medial metatarsal element through a fifth medial metatarsophalangeal joint, the fifth joint having a fifth hinge joint; a lateral phalanx element movably connected to the lateral metatarsal element through a sixth lateral metatarsophalangeal joint, the sixth joint having a sixth hinge joint; an elastic actuation element havi
