Abstract: An adjustable length strut includes two joints, a threaded rod extending between the joints, and a tube adapted to receive the threaded rod. An actuation mechanism with gear teeth extending radially outward of the strut axis is rotatably fixed to the threaded rod. A protrusion may be coupled to an end of the threaded rod by a rotatable collar, with the protrusion extending through a slot in the tube to mark the length of the strut. A modular attachment member may be adapted to be couple to the first joint and include a worm gear adapted to engage gear teeth of the actuation mechanism. The modular attachment member may include a radiofrequency identity tag mechanism adapted to be read by a tag reader of a tool, the tool adapted to couple to the attachment member to rotate the worm gear to increase or decrease the effective length of the strut.

Abstract: An external fixation system includes first and second fixation members having first and second pluralities of mounting holes, respectively. The first and second plurality of holes are configured to receive first and second ends of a plurality of struts, each strut having a default or initial mounting position. A simulation of the correction may be performed with the struts in the default positions, but it may be determined that the correction is not achievable. Additional simulations of the correction may be performed with the ends of the struts in different mounting positions to determine if other mounting positions of the struts allow the correction to be completed. During the correction, if one of the struts reaches a maximum length, it may be disconnected and reconnected to a different mounting hole so that, after being reconnected, the strut may be further increased in length to continue the correction.

Abstract: Disclosed herein are strut attachments for external fixation frames. The strut attachments provide solutions for frame configurations in which it is not possible to attach a strut at its ends to corresponding rings. The strut attachments may be considered an outrigger type of mechanism that achieves more travel out of completely collapsed struts. The strut attachments, each having a pivot and a hinge joint, allow a strut to be attached on the level of a first ring and extend at least partially proximally or distally to a second ring depending on the frame of reference of the ring system. These strut attachments may be used when the fully collapsed length of the strut will not allow the rings to get any closer to one another than is needed or proscribed. In such cases, the strut attachments allow for even tighter ring to ring distance.
