20130325072 | INTERCHANGEABLE ORTHOPEDIC BLADE - An interchangeable orthopedic blade that includes an internal portion and an external portion. The internal portion threads onto either a pre-installed K-wire or a pre-installed screw so as to more accurately place the interchangeable orthopedic blade in, without excessive damage to, the bone when repairing a fracture in the bone, and ultimately providing absolute stable fixation by the interchangeable orthopedic blade holding the fracture in its anatomic position and resisting applied forces while healing, to thereby provide a stable anatomic restoration and eliminate a need for revision surgery due to failure of fixation or malunion. The internal portion is received in the external portion, and rotates relative to the external portion, but has the external portion move non-rotatably axially with the internal portion into the bone as the internal portion threads onto either the pre-installed K-wire or the pre-installed screw. | 2013-12-05 |
20130325073 | Bone Anchors, Kits, and Methods for Securing Portions of Bone - Embodiments of apparatuses, kits, and methods for securing portions of bone (e.g., for an osteotomy). | 2013-12-05 |
20130325074 | ORTHOPEDIC DEVICES WITH A LOCKING MECHANISM - Disclosed embodiments relate to an orthopedic device including a plate and a single-step self-locking mechanism. The plate includes one or more tapered apertures and a slot defined in a top surface of the plate, the slot extending from each aperture. The locking mechanism is slidably seated in the slot and is operable to be positioned in a first position along the slot where a portion of the locking mechanism extends over the aperture or positioned in a second position along the slot where the portion of the locking mechanism is fully retracted from the aperture. | 2013-12-05 |
20130325075 | Polyaxial bone screw assembly - A polyaxial bone screw assembly includes a shank body having an upper head portion with a mating segment and a first partial spherical surface, a retainer structure being mateable with the mating segment of the upper head portion, the retainer structure having a second partial spherical surface such that when mated, the first and second partial spherical surfaces form a spherical ball member, a receiver defining an open channel and having a base with a seating surface partially defining a cavity with a shaped wall, the open channel communicating with the cavity, the cavity communicating with an exterior of the base through an opening sized and shaped to receive the shank upper head portion therethrough, and a bushing sized and shaped to fit within open channel and cavity and lock in recesses on interior of receiver. | 2013-12-05 |
20130325076 | LOWER EXTREMITY FUSION DEVICES AND METHODS - A fusion implant and fusion members for fusing target fusion bones of a lower extremity. The fusion implant including internally threaded apertures of a first thread lead, and fusion members including threading of the first thread lead and threading of a second thread lead that is less than the first thread lead. The fusion implant and a targeting instrument being configured to couple to one another in a predefined orientation. The predetermined orientation resulting in alignment of aspects of the fusion implant with aspects of the targeting instrument. The targeting instrument providing both distraction and compression to the joint between the target fusion bones. A guide instrument for preparing one of the target fusion bones for fusion thereof. A surgical method for applying compression to the joint between the target fusion bones to facilitate fusion thereof utilizing a fusion implant, fusion members, a targeting instrument and a guide instrument. | 2013-12-05 |
20130325077 | DISTAL INTERPHALANGEAL FUSION METHOD AND DEVICE - A system, including methods, apparatus and kits for connecting bones and/or bone portions using a multi-part bone connector with one or more rotating joints is disclosed. A flexible bone fusion apparatus is provided having an anchor and a compressor, each of which engages with a coupler to provide axial and/or linear rotation of the apparatus. Alternatively, a compressor and an anchor may directly join with each other at a shared interface. Tools for installing and compressing the apparatus are provided. Also provided is a method for fusing two bones or bone portions to create a non-linear post-fusion orientation. A further aspect of the disclosure is a method for maintaining thread synchronization of a bone fusion apparatus having a discontinuous thread. | 2013-12-05 |
