    Abstract: The embodiments provide provides devices, instruments, and associated methods for treating joint pain. A joint is evaluated using magnetic resonance imaging to detect any defects in the subchondral bone. For example, using T2-weighted MRI images, bone marrow lesions or edemas can be identified, and using T1-weighted MRI images, associated regions of sclerotic bone adjacent to the bone marrow lesion can be identified. The treatment method may involve introducing a bone void filler material at the site to address the bone marrow lesion or edema, and/or drilling and inserting an implant to address the sclerotic bone, bone marrow lesion or edema, and insufficiency or stress fractures. An access path is mapped to a location in the subchondral region where the insufficiency fracture resides. The access path attempts to preserve an articular surface of the joint. A reinforcing member that stabilizes the insufficiency fracture is then implanted via the access path.

  • Patent number: 8231629
    Abstract: The present invention relates to alignment systems and methods for detecting a distal hole of an intramedullary nail. A jig is attached to the proximal end of the nail and also mounted on the bone. The jig has an adjustable positioning head that includes a drill axis hole along with an alignment pin. The alignment pin includes reference marks that are visible in X-ray images and helps to align the positioning head drill axis with the distal hole of the intramedullary nail. A light source is insertable into the nail in order to shine light out of the distal hole to illuminate a spot on the bone surface as an alignment aid. Viewing optics are mountable on the positioning head for viewing the illuminated spot created by the light source in the intramedullary nail.

    Abstract: Improved methods and apparatuses for inserting pedicle screws in accordance with embodiments of the present invention include an image correction algorithm. In various embodiments, an original image of a region of interest of a patient including a pedicle is created with an X-ray emitter and an X-ray detector. Due to the X-ray emitter not being aligned orthogonal to the X-ray detector, the original image will be skewed.

  • Patent number: 8016835
    Abstract: A system for guiding an implant to an optimal placement within a patient includes a trajectory guide for guiding instruments along a selected trajectory and a trajectory fixation device for fixing the trajectory guide in a selected position. The trajectory guide defines a path configured to align with the selected trajectory. A movable support mounts the trajectory guide and selectively moves the trajectory guide to align the trajectory guide with the selected trajectory prior to fixing the trajectory guide in the selected position. The trajectory is aligned coarsely by hand, then the trajectory is aligned using a fine adjustment system. After fixing the trajectory guide, instruments can be inserted along the trajectory through the path defined by the trajectory guide.

  • Publication number: 20110130765
    Abstract: A novel coplanar X-ray guided method and device for insertion of distal locking screws in intramedullary bone nails. The device has coplanar holes, which allow insertion of protective sleeves. A drill and bone screws can be inserted through the protective sleeves. Radiopaque target markers in the aiming arm enable the easy positioning of an X-ray source such that an X-ray beam is coplanar with the aiming arm transverse holes. After the X-ray source is accurately oriented, a single X-ray snapshot is enough to assess the exact distortion of the implanted intramedullary nail. The X-ray beam need not be coaxial with the intramedullary nail holes. The aiming arm has a mobile portion and a fixed portion fastened to the nail, wherein said aiming arm can be adjusted, displacing the mobile portion over the fixed portion, to compensate for the distortion of the intramedullary nail after implantation.

  • Publication number: 20110077657
    Abstract: Apparatus and methods are provided for aligning a bone-penetration device with a nail-hole at a distal end of an implantable nail. A lateral x-ray image of a drill-guide and the distal end of the nail is generated by: orienting an x-ray source with respect to the drill-guide, using a coupling device; and generating a lateral x-ray image of the drill-guide and the distal end of the nail, while the x-ray source is oriented with respect to the drill-guide. It is determined that the drill-guide is aligned with the nail-hole by determining that, in the image: (a) a line corresponding to a longitudinal axis of the drill-guide, and (b) a line corresponding to a longitudinal axis of the distal end of the nail are substantially collinear. In response thereto, the bone-penetration device is aligned using the drill-guide.

  • Patent number: 7901410
    Abstract: An intramedullary nail and a targeting and/or nailing instrument includes a connector end which has an axially parallel projection which cooperates with an axially parallel recess on the hollow connection end of the nail. The engagement of the projection and recess fastens the nail under axial engagement on the connection end of the instrument in predefined rotational position on the instrument. A quick-fastener element engages in the connection end of the nail and has a first coupling element and the connection end of the nail has a second coupling element. The coupling elements are configured so that in a first rotational position relative to the axially parallel projection the instrument can be introduced into the connection end of the nail and in a second rotational position the coupling elements cooperate so that the nail is held axially fixedly on the instrument.

    Abstract: An alignment jig that creates a plurality of parallelograms may be used to align an external alignment line with an internal target path. The internal target path is within the patient's body and may be defined by two guide pin tips. The alignment jig may be created so that it creates the external alignment line to be co-linear with the internal target path or the external alignment line may be parallel to the internal target path by offset a distance from being co-linear. The external alignment line may be used in the provision of therapy such as the delivery of a screw to a precise location in the provision of therapy to a portion of the spine.

  • Patent number: 7643868
    Abstract: In order to establish an optimum position on the upper side of the tibia for the exit point of an anterior cruciate ligament replacement, it is proposed that, with the leg bent, the position of a number of points along the front edge of the notch is detected and in this way their position and progression on the femur are also determined, that, with the leg straight, the course of this front edge of the notch is projected onto a projection plane which is perpendicular to the longitudinal axis of the tibia in the region of the upper side of the tibia, and that, within the region enclosed by this projected curve, the exit point is selected such that it maintains at least a distance corresponding to the radius of the implant from the projected curve. Furthermore, an apparatus for carrying out such a method is proposed.
