A bone transport device may include a first support member, a second support member, a plurality of first rods, a cable, and a plurality of actuator assemblies. The cable may be configured to be received through a first bone segment. The bone transport device may further include a second rod that is configured to extend through the first bone segment such that the cable abuts a portion of the second rod within the first bone segment. The plurality of actuator assemblies may be attached to the first support member or the second support member. Each of the plurality of actuator assemblies may include a body, a spool, and an actuator. The actuator may be configured to rotate the spool to wind the cable onto the spool and translate a second bone segment with respect to the first support member and the second support member.

Cable bone transport device

An strut assembly extends along a strut axis and comprises a strut body, an actuator, and a locking assembly. The strut body includes a rod and a sleeve. The rod is translatable relative to the sleeve along the strut axis. The actuator is linearly engaged with the sleeve such that linear movement of the actuator causes linear movement of the sleeve. The locking assembly includes a lock member configured to transition between a locked position in which the lock member engages both the sleeve and the actuator such that rotation between the sleeve and the actuator is substantially prevented, and an unlocked position in which the lock member is spaced apart from the sleeve such that the actuator is substantially free to rotate about the sleeve.

Locking system and method

A computer-implemented method for producing a treatment plan to control manipulation of a fixation apparatus including a first element and a second ring and struts to correct an anatomical structure deformity of first and second anatomical structure segments, including: receiving, using one or more graphical user interfaces of a computing system, configuration information associated with the fixation apparatus, the configuration information comprising one or more geometric characteristics of one or more elements of the fixation apparatus and ring deformation information; receiving, by the computing system, images of the fixation apparatus and the first and the second anatomical structure segments attached thereto; determining, by the computing system, based on the configuration information and the received images, positions and orientations of the first and the second anatomical structure segments in three-dimensional space relative to the fixation apparatus; determining the hole locations of the first element based upon the deformation information; determining, by the computing system, manipulations to the fixation apparatus for correction of the anatomical structure deformity, the manipulations comprising adjustments to the struts based upon the determined hole location of the first element; and providing, by the computing system, to one or more users, indications of the manipulations to the fixation apparatus.

Perspective frame matching process for deformed fixation rings

Female polyaxial joints for connecting a strut to a support frame of an external fixation device are described having a ball socket and a ball member. The ball member includes a spherical portion and a ball member shaft extending from the spherical portion. At least one aperture is positioned on the ball member and traverses through at least a portion of the ball member shaft. An internal surface of the ball member shaft may be threaded and configured to receive a threaded connector.

Female polyaxial joint and method of using same

A plurality of three-dimensional fixator graphical representations may include graphical indications of a strut swap range. A plurality of replaced strut graphical representations may change from a first rendering state in a swap start fixator graphical representation to a second rendering state in a swap end fixator graphical representation. A plurality of replacement graphical representations may change from the second rendering state in the swap start fixator graphical representation to the first rendering state in the swap end fixator graphical representation. In some examples, the plurality of replaced strut graphical representations may gradually fade out from a swap start stage to a swap end stage, and the plurality of replacement strut graphical representations may gradually fade in from a swap start stage to a swap end stage. Additionally, a treatment plan including at least one interfamily strut swap may be generated for manipulating a fixator to correct a deformity.

Orthopedic fixation strut swapping

A system for inserting an anchor member into bone includes a receiving member and an anchor member receivable within the receiving member. The receiving member is elongate along a longitudinal axis and has a proximal end and a distal end spaced from the proximal end along the longitudinal axis. The receiving member has an internal surface that defines a transmission element. The anchor member includes an engagement element configured to rotatably engage the transmission element such that the transmission element is configured to drive the anchor member in a distal direction relative to the transmission element so as to rotatably decouple the engagement element from the transmission element. The distal direction extends from the proximal end to the distal end of the receiving member and is parallel with the longitudinal axis.

Orthopedic break-off screws, tools for inserting such screws, and related systems and methods

A polyaxial external fixation strut including a strut member and a first ball joint coupled to an end portion of the strut member. The first ball joint includes a first ball joint body and a first ball member. The first ball member is rotatably coupled to the first ball joint body to allow for variable angle adjustable positioning of the first ball member within the first ball joint body. The first ball joint additionally includes a friction member. The friction member is configured to create friction between the first ball member and the first ball joint body.
