An automated and/or motorized spatial frame including a control unit and a plurality of motorized struts is disclosed. The control unit being configured as a controller for exchanging data with an external computing system, exchanging data with the plurality of motorized struts, and delivering power to the motorized struts. Thus arranged, the control unit may be configured as a fully integrated power supply and controller for powering and controlling the motorized struts. In some embodiments, the control unit includes a plurality of PCB modules, each positioned within the spaces or pockets formed between adjacent tabs on a ring of the frame. The PCB modules being detachably coupled to the ring. In some embodiments, the PCB modules may be detachably coupled to the ring via interconnecting male and female connectors. Alternatively, the PCB modules may be detachably coupled to the ring via a plurality of brackets.

The present technology relates generally to ring fixators and associated systems and methods. In some embodiments, for example, a ring fixator assembly comprises a ring configured to surround a fractured bone, a retention device disposed at a first position on the ring, and a tensioner clamp disposed at a second position on the ring. A wire extends between the retention device and the tensioner clamp. The tensioner clamp includes a first screw configured to secure the wire in position with respect to the tensioner clamp and a second screw configured to apply additional tension to the wire.

An adjustment compliance device and systems and methods for use with an external fixator are disclosed. The adjustment compliance device can be attached to a strut of an external fixator and may include at least one indicator element to indicate adjustment parameters for an active step of an adjustment process for the external fixator. The adjustment parameters may include an active strut and/or a direction of adjustment for the strut. The adjustment compliance device may receive the adjustment parameters from a user device. The at least one indicator element may include a light element operative to emit light in a color corresponding to the active strut. The at least one indicator element may include a light element configured to indicate a direction of rotation of the active strut. As a result, a patient can more effectively comply with an adjustment prescription, thereby improving the likelihood of successful bone alignment.

Logic may determine how to reduce bone segments. Logic may communicate one or more images to display with at least two bone segments. Logic may identify a first reduction point and a third point on a first bone segment and identify a second reduction point and a fourth point on the second bone segment. Logic may identify a fifth point on the first bone segment and a sixth point on the second bone segment. Logic may also divide the one or more images along a line or plane between the bone segments, bring the second reduction point and the associated image segment to the first reduction point, align the line or plane of the second bone segment with a line or plane of the first bone segment. Furthermore, logic may adjust alignment and record the movement of the image segments or compare original and final positions, to determine deformity parameters.

A method of generating a correction plan for correcting a deformed bone includes inputting to a computer system a first image of the deformed bone in a first plane and inputting to the computer system a second image of the deformed bone in a second plane. Image processing techniques are employed to identify a plurality of anatomical landmarks of the deformed bone in the first image. The first image of the deformed bone is displayed on a display device. A graphical of the deformed bone is autonomously generated and graphically overlaid on the first image of the deformed bone on the display device, the graphical template including a plurality of lines, each line connected at each end to a landmark point corresponding to one of the anatomical landmarks. A model of the deformed bone may be autonomously generated based on the graphical template.

A freely-connectable three-strut parallel orthopedic external fixator including two fixation rings and three struts, connecting holes are circumferentially and uniformly distributed on the ring surfaces of each fixation ring, each strut is provided with two driving translational pairs, a revolute pair and a spherical pair. Two fixation rings are respectively fixedly connected with the bone segments of the fracture site by using medical metal bone pins; adjusting the driving translational pairs of the six struts can achieve six DoF relative movement of the two fixation rings, thereby achieving fracture reduction. The external fixator of the present invention realizes free connection between the two fixation rings, which facilitates fixator installment; number of struts is less than the existing external fixators.

An external fixator utilized in orthopedic surgeries such as the repair of segmental fractures, correction of congenital or development deformities, and limb lengthening. The external fixator is comprised of half rings that utilize connectors to form full rings, threaded rods that fit into rod holes, channel slots, wires that pass through bone and soft tissue, and fixation bolts that can be positioned with minimal effort by a surgeon, minimal pain to a patient, and minimal risk of infection.
