Abstract: An implant insertion assembly including an insertion handle extending from a proximal end to a distal end, the distal end including a recessed portion, an outer wall of the recessed portion having a first shape about a perimeter thereof and including an engagement mechanism. The implant insertion assembly also includes an implant extending from a distal end to a proximal end including an opening configured to receive the recessed portion of the insertion handle, the opening having a second shape configured to mechanically interlock with the outer wall of the recessed portion when the recessed portion is inserted therein to transmit torque from the insertion handle to the implant, the proximal end including a receiving structure in a wall thereof, the receiving structure being positioned and oriented to receive the engagement mechanism to removably lock the insertion handle to the implant in the axial direction.

Abstract: In one embodiment, an intramedullary nail has a body that includes proximal and distal ends and an inner surface that defines at least one locking hole that extends into an outer surface of the body so as to receive a bone anchor to lock the nail in a medullary canal of a bone. The body has a first biocompatible material that defines at least a portion of the outer surface. The nail has a second material that is different from, and at least partially encapsulated in, the first material. The second material can produce at least one of an electrical current and a magnetic field, and is supported by the nail body such that a position of the at least one bone-anchor locking hole can be detected based on the at least one of the electrical current and the magnetic field.

Abstract: Intramedullary fixation assemblies (4, 8) and intramedullary fixation devices (1, 24) can be used in orthopaedic surgery for the fixation of bone fractures. Also disclosed is an insertion device (30) for inserting an intramedullary fixation device, and a method of fixing a bone fracture. The fixation devices are preferably for addressing fractures of the distal radius, and are preferably styloid nails. The styloid nails preferably have a head portion that can accept up to three bone screws; one of the bone screws is designed to extend across a fracture line between a proximal and a distal bone fragment while the other bone screws are designed to be retained in the distal bone fragment.

Abstract: A bone fixation plate comprises a plate body extending from a first end configured for placement over a shaft of a bone to a second end configured and dimensioned for placement over an epiphysis of the bone, an outer diameter of the plate body increasing from the first end to the second end to substantially conform to dimensions of the bone. An opening extends through the plate from a first surface which faces away from the bone when mounted thereonto to a second surface which faces the bone when in the desired orientation, the opening being positioned so that, when mounted over the bone, a fracture of the bone is visible therethrough to aid in alignment of the bone plate. First and second holes extend through the plate, each of the first and second holes being structured to lockingly engage a threaded head of a bone fixation device inserted thereinto.

Abstract: Implants and methods for osteopathic augmentation and repositioning of vertebrae may comprise a chain having one or more beads or bodies configured for insertion into a vertebral body. The one or more bodies may be expandable. As the chain is inserted into the vertebral body, it may fill a central portion thereof and can push against the inner sides of the endplates of the vertebral body, thereby providing structural support and tending to restore the vertebral body to its original height. The one or more bodies may have a first configuration dimensioned to pass through a catheter or other introducer, and may expand to a second, larger configuration after insertion into the bone in order to secure the chain within the bone.

Abstract: Apparatuses and methods of treating a collapsed vertebra may include inserting cannulae into the damaged vertebral body and one or more adjacent vertebral bodies and repositioning the one or more adjacent vertebral bodies by manipulating one or more of the cannulae. Before or after repositioning the vertebral bodies, the method may further include passing through the cannula and into the damaged vertebra a disruption tool for fracturing the damaged vertebral body. Once the cortical bone is broken or otherwise disrupted, the height of the damaged vertebral body may be restored, for example by removing the disruption tool and inserting through the cannula another tool, implant, device and/or material to restore the height of the vertebral body and to restore normal spinal curvature in the affected area. Bone cement, bone chips, demineralized bone or other grafting material or filler may be added with or without an implanted device to augment the damaged vertebral body.

Abstract: The invention relates to a trochanter stabilizing device (40), especially for fixing bone fragments in the region of the hip joint (11) or for fixing the greater trochanter (12), including A) bone stabilizing means (1) consisting of a central plate (2) with at least one fixing perforation (13) for receiving a bone fixing means (20); B) a longitude bone plate (30) with a bushing (31) arranged at an angle for receiving a fixing element (50) which can be introduced into the region of the hip joint (11) fixed thereto, whereby C) at least three peripheral arms (4) originate from the central plate (2), whereby D) each peripheral arm (4) is provided with at least one hole (5) for receiving a bone fixing means (20).

Abstract: Implants and methods for bone treatment, preferably minimally invasive treatment, including repositioning of vertebrae may comprise insertion of a bobbin having a wire, string, thread or band, coiled around the bobbin. During coiling, the diameter of the bobbing/band complex may increase. Such increase in diameter can push against the inner side of the endplates of the vertebral body, and augment the vertebral body to its original height. The implant may also take the form of a coiled sleeve which when inserted into the vertebral body is uncoiled. The force of the uncoiling sleeve pushes against the inner side of the endplates of the vertebral body, restoring the vertebral body to its original height.

Abstract: Implants and methods for minimally invasive augmentation and repositioning of vertebrae may comprise one or more expandable members, e.g., stents, implants, surrounding a balloon-tipped catheter or other expansion device, inserted into a vertebral body or other bone. Expansion of the expandable member within the vertebral body or other bone may reposition the fractured bone to a desired height and augment the bone to maintain the desired height. A bone cement or other filler can be added to further augment and stabilize the vertebral body or other bone.
