| 20100082071 | Composite Screw Having A Metallic Pin and a Polymeric Thread - A composite screw preferably made of a metallic pin embedded in a polymeric tubular structure having the outwardly facing threads, wherein the metallic pin comprises a screw head, an intermediate shaft and a screw tip, and the polymeric threaded tube is either molded onto the metallic shaft or the threaded is machined after molding a polymeric structure onto the shaft. | 04-01-2010 |
| 20100280558 | PEDICLE SCREW ASSEMBLY HAVING A RETRACTABLE SCREW TIP FOR FACILITATING THE SECUREMENT OF THE PEDICLE SCREW ASSEMBLY TO A SPINAL VERTEBRA - A pedicle screw assembly has a retractable screw tip that facilitates the securement of the pedicle screw assembly to a spinal vertebra in a minimally invasive fashion during an orthopedic surgical procedure. The pedicle screw assembly includes a body portion including a head and a shank. The shank includes an outer surface with a thread provided thereon, an end having a cutting tip provided thereon, and a bore extending inwardly from the end and having an internally threaded region provided therein. The pedicle screw assembly also includes a tip portion including a body having a cutting edge and a shank extending from the body. The shank has an externally threaded region provided thereon that cooperates with the internally threaded region of the bore to permit movement of the tip portion relative to the body portion between extended and retracted positions. | 11-04-2010 |

| 20120283790 | SELF GUIDING SURGICAL BONE FIXATION SCREW - A surgical bone fixation screw having a head, an end segment distally from the head and an intermediate shank having outwardly protruding screw threads. The improvement is a self guiding, threadless, elongated end segment having a smooth outer surface with no cutting edges, a length of at least 8 mm and preferably 15 mm and a bluntly rounded end with an outer contour that is smoothly blended to the shank. Most preferably, the bluntly rounded end is substantially a prolate hemispheroid. | 11-08-2012 |
| 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. | 12-05-2013 |
| 20140081340 | Apparatus And Method For Sternal Closure - The present disclosure provides a sternal closure fixation device. The fixation device includes a first sternum implant disposable within an interior cavity of a first half of a severed sternum such that the first implant contacts opposing anterior and posterior faces of the cavity. The fixation device additionally includes, a second sternum implant disposable within an interior cavity of a second half of a severed sternum such that the second implant contacts opposing anterior and posterior faces of the cavity. Furthermore, the fixation device includes a rigid fixation pin sized and structured to be disposed within an internal bore of the first implant and within an internal bore of the second implant, whereby when the first and second halves of the severed sternum are joined together, the first and second halves of the sternum are prevented from shear movement in any direction relative to each other. | 03-20-2014 |
