  • Publication number: 20220110638
    Abstract: Device and method for reaming bone. In exemplary embodiments, the device may comprise a shaft configured to be rotated about a long axis thereof. The device also may comprise a plurality of cutting members connected to a distal end region of the shaft, rotationally offset from one another about the long axis, and forming a portion of an expandable cutting head. The device further may comprise an inner member configured to be moved with respect to the shaft to change a diameter of the cutting head. In exemplary methods, the device may be utilized to ream a medullary cavity while being pushed or pulled along the medullary cavity.

  • Publication number: 20220079636
    Abstract: Devices and methods for stabilizing bone. An exemplary device may comprise a plate, an arm, and a buttress member. The plate may define one or more apertures configured to receive one or more fasteners that secure the plate onto a first bone region. The arm may project from an edge of the plate. The buttress member may be connected pivotably to an end of the arm. The buttress member may be configured to be pivoted by contact with a second bone region to conform an orientation of the buttress member to the second bone region, and may apply compression to, and/or support, the second bone region.

  • Publication number: 20210259709
    Abstract: Bone harvesting system including methods and devices for obtaining and/or removing osseous debris from a bone using an auger having a flexible, helical fin projecting from a shaft. In an exemplary method, a leading end region of the auger is placed into a reamed portion of a bone's medullary cavity via an entry site extending into the bone. Osseous debris is driven toward the entry site with the auger. At least a portion of the osseous debris that has passed through the entry site is collected outside the bone. In some embodiments, the leading end region of the auger is deformed by contact between the helical fin and a wall of the medullary cavity, to conform the helical fin in the leading end region to a portion of the medullary cavity.

  • Publication number: 20200352729
    Abstract: System, including apparatus and methods, for ankle fusion using a device for separating a first bone and a second bone of an ankle region. In some embodiments, the device may comprise an expandable spacer including first and second bone-contacting surface regions facing away from one another and configured to be abutted with the first and second bones, respectively. A distance between the first and second bone-contacting surface regions may be adjustable to change the separation of the first and second bones. The first bone-contacting surface region may correspond to a portion of a sphere and may be configured to be disposed at least partially in a concavity formed surgically in the first bone. The expandable spacer offers improved control over the length of the lower limb and the orientation of the foot during ankle fusion surgery.

  • Publication number: 20200345398
    Abstract: Systems and methods for fixing bone using an intramedullary nail locked to an encircling anchor including a bushing and a locking member. An exemplary system may include any combination of the nail, one or more bushings, one or more locking members, an instrument to guide installation of the bushing, at least one drill, and a driver that attaches to the bushing. The instrument may define a guide axis and be configured to be coupled to a bone such that the guide axis extends across the bone. The instrument may be used to guide a drill, the bushing, and/or the locking member along the guide axis into the bone. The nail may be configured to be placed along the medullary canal of the bone such that the nail extends through the bushing, and the locking member may be configured to lock the nail to the bushing.

  • Patent number: 10117685
    Abstract: System, including methods and devices, for bone fixation with a pin and a collar. In exemplary embodiments, the system may comprise a pin configured to be inserted into a bone, and a deformable collar to retain the pin in the bone. The collar may be configured to be operatively disposed on the pin such that the collar extends more than halfway and less than completely around the pin. The pin and the collar may have complementary surface features that discourage sliding of the collar along a long axis of the pin. In some embodiments, the collar may be configured to be operatively disposed on the pin at a plurality of discrete, alternative axial positions along the long axis of the pin. The pin may be cut to a desired length.

  • Patent number: 10080596
    Abstract: System, including methods and apparatus, for hip fixation with load-controlled dynamization. In exemplary embodiments, the system may comprise a fixation element, such as a screw, configured to be placed into a proximal femur of a subject, with a leading end of the fixation element anchored in a head of the proximal femur. The system also may comprise a stop member configured to be connected (e.g., via a nail or plate) to the proximal femur. The system further may comprise a deformable member configured to be irreversibly deformed by compressive force exerted on at least a portion of the deformable member by the fixation element and the stop member in response to a load applied to the proximal femur by the subject, such that the fixation element and the stop member move relative to one another parallel to a long axis of the fixation element.
