| 20110295325 | Bone Plate - A bone plate includes an upper surface, a bone contacting surface, and at least one hole extending through the upper and bone contacting surfaces. The bone plate defines a longitudinal axis. The at least one hole defines a central axis and is elongated in a direction substantially aligned with the longitudinal axis. The hole may include a threaded portion and a non-threaded portion, and the threaded portion may extend through an angle of between about 190° and about 280° with respect to the central axis. | 12-01-2011 |
| 20110295326 | Bone Plate with Pre-Assembled Drill Guide Tips - Removable drill guide tips are pre-assembled into threaded holes of a bone plate. The tips may be used with an extension to together function as a conventional drill guide. After drilling, the extension or another tool is used to remove the tips from the plate. According to another use, the tip is used as a guide for a drill bit without any additional extension and then removed with a tool. | 12-01-2011 |
| 20090318979 | Locking Plate Benders - A system for contouring a locking plate includes a locking plate and at least one bender. The locking plate includes a plurality of threaded screw holes connected to one another by one or more ribs. The at least one bender includes a threaded tip configured to threadably engage one or more of the plurality of threaded screw holes and a shoulder operable to transmit mechanical force to the locking plate once the threaded tip is threadably engaged with one of the plurality of threaded screw holes. | 12-24-2009 |
| 20080288000 | Cervical plate locking mechanism and associated surgical method - The cervical plate locking mechanism of the present invention is elegant in its design and effective in its performance, and utilizes a plate with holes that each incorporate a locking lip structure and locking screws that each incorporate a head portion having petal structures that are outwardly biased prior to insertion via an internally-disposed c-ring or the like. Advantageously, the lead-in torque of each of the locking screws is less than the lead-out torque of each of the locking screws. Thus, reverse threading or backing out is prevented. | 11-20-2008 |
| 20080234749 | BONE PLATE PROVIDING THREADED LOCKING HEAD SCREW CAPTURE - The present invention relates to orthopedic bone plates, and, more particularly, to orthopedic bone plates having screw receiving apertures formed therein. In one embodiment, the bone plate includes an aperture defined by an interior wall having a threaded portion and a non-threaded portion. In one exemplary embodiment, the threaded portion and the non-threaded portion are configured to engage the head of a bone screw. In another exemplary embodiment, the non-threaded portion of the interior wall is cylindrical and the threaded portion of the interior wall is conical. In another exemplary embodiment, both the non-threaded portion and the threaded portion of the interior wall are conical. In each of these embodiments, a bone screw having a threaded head may be used. In one exemplary embodiment, the head of the bone screw is self-tapping. In another exemplary embodiment, the head of the bone screw is conical. | 09-25-2008 |
| 20080234752 | Surgical plate puller devices and methods for use with surgical bone screw/plate systems - A plate puller device can include a head portion and extension rod portion. The device enables the fastener receiving member to be pulled against a bone surface before a head section of the fastener is advanced within the fastener receiving member into a locked position. The head portion can be positioned between the head section of the fastener and a surface of the fastener receiving member not adjacent to the bone surface. Also, a plate puller device can include a screwdriver, a grasper portion and a grasper sleeve. The grasper portion and grasper sleeve can be threadingly mated wherein rotation of the grasper sleeve forces a head portion of the grasper portion to grip the head section of the fastener to prevent the head section from advancing within the fastener receiving member. | 09-25-2008 |
| 20080234751 | Anterior vertebral plate with closed thread screw - Provided is a novel system that includes a low profile anterior vertebral body plate and closed thread screws for the fixation and stabilization of the cervical spine, the closed thread screw having an integral novel screw locking mechanism of an uppermost closed thread having a flat pitch, which engages and attaches the plate so as to lock the screw into the plate until an intentional, simultaneous combination of outward pulling force and counter-clockwise torque is applied to release the closed thread screw from the plate. Also provided is a method of stabilizing cervical vertebrae using the disclosed system. | 09-25-2008 |
| 20080234750 | Anterior vertebral plate with taper lock screw - Provided is a novel system that includes a low profile anterior vertebral body plate and taper lock screws for the fixation and stabilization of the cervical spine, the anterior vertebral plate having a novel screw locking mechanism attached to the screw during the manufacturing thereof and providing a taper lock fit with the anterior vertebral plate. Also provided is a method of stabilizing cervical vertebrae using the disclosed device. | 09-25-2008 |
| 20090275990 | ANTERIOR CERVICAL PLATE WITH LOCKING MECHANISM - An anterior cervical plating system is disclosed that includes an anterior cervical plate with a locking mechanism feature, bone screws, and a locking element. The bone screws fasten the anterior cervical plate to the spinal vertebrae and locking elements are inserted into a housing to prevent withdrawal of the bone screws from the vertebrae. The anterior cervical plate has at least one pair of adjacent bone screw holes, with the housing mounted perpendicularly between adjacent bone screw holes. When the bone screws are fully inserted into the vertebrae through the anterior cervical plate, the locking element prevents the retraction of the bone screws from the vertebrae. The elastically-deformable locking element holds the bone screws inside the screw holes. | 11-05-2009 |
| 20120310289 | FLEXIBLE PLATE FIXATION OF BONE FRACTURES - Embodiments provide methods, apparatuses, and systems for fixation of a fractured bone with a bone plate. In various embodiments, the systems and plates provide elastic suspension of the receiving holes relative to an osteosynthesis plate. This elastic suspension can promote load distribution between the screws that connect a bone segment to the plate, thereby reducing stress risers and load shielding effect. In addition, stress at the screw holes, and within the construct as a whole, is reduced by incorporation of these elastic elements in the plate. Additionally, in some embodiments where fracture healing by callus formation is desired, elastic suspension of the receiving holes relative to the osteosynthesis plate can enable small, controlled amounts of relative motion between bone fragments connected by the plate. This relative motion can promote fracture healing by callus formation. | 12-06-2012 |
| 20110166607 | Bone Plate With Pre-Assembled Drill Guide Tips - Removable drill guide tips are pre-assembled into threaded holes of a bone plate. The tips may be used with an extension to together function as a conventional drill guide. After drilling, the extension or another tool is used to remove the tips from the plate. According to another use, the tip is used as a guide for a drill bit without any additional extension and then removed with a tool. | 07-07-2011 |
| 20120059425 | Locking Element for a Polyaxial Bone Anchor, Bone Plate Assembly and Tool - A locking element is configured to be used with a polyaxial bone anchor, and is substantially cylindrical with a bottom side facing a head of the bone anchor, a top side opposite to the bottom side, and a surface portion with an external thread. The locking element has a first recess at the bottom side for accommodating at least a portion of the head, and a second recess at the top side for engagement with a driver. The second recess is located outside the center of the top side. The head has a portion with a largest diameter, and a first level L | 03-08-2012 |
