| 20100211118 | BONE SCREW AND METHOD OF MANUFACTURING SAME - The invention relates to a self-tapping bone screw, in particular for use as a compression screw or a locking screw for an implant. The bone screw has screw shank, which has a front tip, a cutting region, an intermediate region and a rear head region. In a transition region comprising mutually adjoining parts of the cutting region and the intermediate region the root diameter of the screw shank in the cutting region is greater than the root diameter of the screw shank in the intermediate region, and the outside diameter of the screw shank is constant. | 08-19-2010 |
| 20110040339 | SURGICAL SCREW AND METHOD OF PERFORMING LIGAMENT RECONSTRUCTION USING SAID SCREW - This invention relates to a system and a method for affixing soft tissue to bones. The system for fixing soft tissue within a bone tunnel comprising a first fixation member having a proximal end and a distal end and a bore extending from said proximal end to said distal end, said first fixation member is adapted for insertion against a first portion of a soft tissue positioned within a bone tunnel, a second portion of said soft tissue emerging from said bone tunnel; a second fixation member adapted to engage said bore of said first fixation member, having means for restraining disengagement therewith and a proximal end; and a third fixation member adapted to engage said second portion of said soft tissue, having means for coupling onto said proximal end of said second fixation member and restraining disengagement therewith. | 02-17-2011 |
| 20110125197 | Limiting radial preloads in securing an orthopedic fastener - An orthopedic fastener rated to be received into a corresponding bone specimen. The corresponding bone specimen has (1) an overall outer thickness from near cortex to far cortex in a predetermined rated range of outer bone thicknesses, and (2) a predetermined bone hole preparation including an entry portion in the near cortex. The entry portion has a predetermined minimum entry diameter. The fastener provides a tapered portion. When the fastener is operably secured into the far cortex of a bone thickness for which it is rated to be received, the tapered portion of the fastener contacts the entry portion in the near cortex so as to impart no more than about 0.2 mm of radial preload into the bone surrounding the entry portion. | 05-26-2011 |
| 20110125198 | Engaging predetermined radial preloads in securing an orthopedic fastener - An orthopedic fastener rated to be received into a corresponding bone specimen. The corresponding bone specimen has a predetermined bone hole preparation including a tapered female threaded section. Threads on the tapered female threaded section have a pre-selected thread profile. The fastener itself comprises a male tapered threaded portion. Threads on the male tapered threaded portion are rated to mate, according to the pre-selected thread profile, with corresponding threads on the tapered female threaded section. The pre-selected thread profile has a predetermined thread geometry. The thread geometry is predetermined so that, when the male tapered threaded portion on the fastener is fully engaged in the tapered female threaded section on the bone hole preparation, a predetermined further tightening of the fastener imparts a corresponding predetermined radial preload on bone tissue surrounding the tapered female threaded section. | 05-26-2011 |
| 20110125199 | Tapered Threaded Orthopedic Fastener Engaging Predetermined Radial Preloads - An orthopedic fastener rated to be received into a corresponding bone specimen. The corresponding bone specimen has an overall outer thickness from near cortex to far cortex. Preferably, but optionally, the corresponding bone specimen also has a predetermined bone hole preparation which includes a pilot hole through the near cortex and into the far cortex. The fastener itself comprises a plurality of cutting flutes on one end. The cutting flutes transition into a tapered male threaded portion. The tapered male threaded portion provides a plurality of self-tapping threads. The self-tapping threads taper from a minimum thread crest diameter D | 05-26-2011 |
| 20110137354 | BONE SCREW - A bone screw includes a tubular body including a wall having a bone thread in at least a portion of an outer portion of the wall, an open first end and an open second end. A plurality of cutting teeth is provided at the open first end. An engagement structure is provided at the second end for engagement with a screwing-in tool. The wall in the vicinity of the plurality of cutting teeth is thicker in a radial direction than the wall adjacent to the plurality of cutting teeth. | 06-09-2011 |
| 20130296952 | SELF TAPPING INSERT - A fixation component for a bone-supporting component of a bone implant, comprising a body including a core, and a head portion. A distal end of the component comprises an insert formed of a hard material, which covers a portion of the distal end, and acts a thread cutting tool. In some embodiments, the insert comprises a planar portion abutting against a material of the fixation component. In some embodiments, the fixation component is a screw, and the insert covers at least a portion of a cutting edge of the screw. | 11-07-2013 |
| 20130338722 | COMPRESSION BONE SCREW - A compression bone screw ( | 12-19-2013 |
| 20140012335 | BONE SCREW AND METHOD OF MANUFACTURING SAME - Disclosed is a self-tapping bone screw, in particular for use as a compression screw or a locking screw for an implant. The bone screw has screw shank, which has a front tip, a cutting region, an intermediate region, and a rear head region. In a transition region including mutually adjoining parts of the cutting region and the intermediate region, the root diameter of the screw shank in the cutting region is greater than the root diameter of the screw shank in the intermediate region, and the outside diameter of the screw shank is constant. | 01-09-2014 |
| 20140058460 | Orthopedic fastener device - An orthopedic structure includes a method for making a threaded fastener with thread geometry and leading edge geometry which provides greater precision during installation. Specifically, thread pitch and tooth profiles are independently variable. A leading portion of the fastener advances bone shards forward of the forward of the fastener to reduce insertion torque and prevent the shards from residing in the upstream tooth profile for better retention. | 02-27-2014 |
| 20140094859 | Medical fastener - A dual-start fastener is disclosed having two threads helically wound about its shaft. The thread tooth profile (in section) constitutes substantially parallel upper and lower facets on each thread flank. A first thread has a crest diameter greater than a second thread. A distal end of the fastener includes self-tapping cutters formed on the threads which force shards of bone to advance into shallow troughs adjacent the cutters for subsequent resorption by adjacent osseous tissue. | 04-03-2014 |
| 20140155943 | BONE IMPLANT - The present invention relates to a bone implant device, comprising a body having a first part and an opposite second part, the first part and an opposite second part defining a longitudinal axis, the first part including an external thread extending from a cylindrical part to the distal end of the body, the external thread comprising a first thread part having a first radius measured from the longitudinal axis and a second thread part having a second radius measured from the longitudinal axis. The first radius is larger than the second radius, the first thread part is a cutting part, and the second thread part is a contact surface. The first part may include one or more cavities for storing bone fragments while the bone implant is in use. | 06-05-2014 |
