    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.

  • Patent number: 8845654
    Abstract: A scaled head frame positioner and tabletop adapter are provided. The positioner may be employed for any neurosurgical procedure that requires fixed positioning of the stereotactic head frame or ring onto a patient's skull. The positioner employs a generally triangular shaped member with Velcro tapes fixed at each corner. The tapes have measurement markings, such as measurement tapes. The positioner supports the head frame with the tapes engaging means on the frame and fastened back to themselves, with markings indicating distances to adjust the position of the frame about the patient's head. Furthermore, the tabletop adapter clamps the patient with a stereotactic head frame onto a CT or treatment table. The tabletop adapter includes a generally U-shaped bracket secured to a support to be placed on the tabletop. The bracket is attachable to the head frame of the patient to hold his head in a desired position.

  • Publication number: 20140236153
    Abstract: The present disclosure relates to software used in planning the correction of bone deformities preoperatively or postoperatively, and in particular relates to virtually manipulating rings and struts of an external fixation frame in order to plan the steps for making a desired correction to two or more bone portions of a patient. The software can be used prior to surgery, allowing a user to virtually define a bone deformity, and virtually add and manipulate fixation rings and struts to the bone deformity. Based on the virtual manipulations, a correction plan can be generated that describes length adjustments that should be made to the plurality of model struts over a period of time to correct the bone deformity. The software can also be used after surgical fixation of the fixation frame and struts to the deformed bone.
