Logic may provide a deformity analysis to create a treatment plan for external fixators. Logic may further perform additional refinements to the treatment plan to improve the patient experience. Logic may further include pre-operative osteotomy to select an osteotomy and to provide real-time updates to a post-operative image based on changes to an osteotomy line, orientation, and/or rotation point. Logic may facilitate movement of one or two portions of a medical image to determine an alignment of bone segments in the portions of the medical image. Logic may generate deformity parameters based on a combination of translations and/or rotations of the movement to align the portions. Logic may create a treatment plan including a prescription for an external fixator based on deformity parameters.

Methods and arrangements for external fixators

A kit and corresponding methods of use are disclosed. In use, the kit includes a plurality of articulating clamps for coupling to one of the rings of an external fixation system. In use, the clamps include a body portion having a stem arranged and configured to be received within an opening formed in one of the rings. The clamp further including a clamp assembly for engaging a rod spanning the first and second rings. Thus arranged, the clamp may be directly coupled to one of the rings and the rod, the clamp enabling the position of the ring to be adjusted relative to the rod. As such, the clamps may enable, inter alia, a hexapod external fixation system to be converted into a static frame, a static frame to be constructed in a more efficient manner, and/or creation of an enlarged visualization or working window.

Conversion kit for an external fixation system

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.

Device for indicating an active component of an adjustable medical apparatus

Embodiments of the invention include an external fixation system that includes at least one external fixation strut that is both acutely adjustable and precisely adjustable and related methods of adjustment. Acute adjustment may be accomplished using one or more mobile jaws that may be engaged with or disengage from a threaded rod of each external fixation strut. Precise adjustment of each external fixation strut may be accomplished after releasing a lock biased toward a locked position. When each external fixation strut's lock is released, a portion of each of the precise adjustment mechanism of each external fixation strut may be activated to increase and decrease the length of each of the at least one external fixation struts.

A reconfigurable bone adjustment device () includes a first member () configured for attachment to a first bone fragment, a second member () configured for attachment to a second bone fragment and a reconfiguration assembly () configured to move the second member relative to the first member. The reconfiguration assembly includes a drive mechanism () and a threaded rod () operatively coupled to the drive mechanism so that rotation of the drive mechanism rotates the threaded rod. The reconfiguration assembly operates to reduces stresses, forces, bending moments and/or eccentric moments on a junction and/or by configuring the junction in a manner whereby one of more of the forces, is isolated away from the junction.

Implantable bone adjustment devices

An intramedullary bone transport nail configured for axial bone segment transport by an externally applied magnetic field includes a nail body defining an internal chamber; locking portions for locking respective ends of the nail body in first and second bone fragments of a long bone, respectively; and a transport carriage assembly that is arranged in an axially movable manner within the internal chamber of the nail body and has an aperture for accommodating a transport bone segment screw for fixing a middle bone segment of the long bone to the bone transport carriage. The nail body defines an elongated longitudinal opening to allow axial motion of the transport bone segment screw as the transport carriage assembly moves axially by rotation of a threaded rod affixed to a magnetic driver. Rotation of the threaded rod is achieved by application of torque to the magnetic driver by a rotating external magnetic field.

Bone transport nail

A reconfigurable bone adjustment device includes a first member configured for attachment to a first bone fragment, a second member configured for attachment to a second bone fragment, the second member including an elongated slot formed therein; a drive mechanism configured to move the second member relative to the first member; a threaded block fixedly coupled to the first member, the threaded block positioned within the elongated slot; and a threaded rod having a proximal end operatively coupled to the drive mechanism, an intermediate portion threadably coupled to the threaded block, and a distal end operatively coupled to the second member so that rotation of the drive mechanism rotates the threaded rod and moves the second member relative to the first member. The second member being adapted and configured to provide increased strength so that the device can withstand increased patient weight bearing.
