20150374418 | Flexible Spinal Driver or Drill With A Malleable Core, and/or Fixed Core Radius - The improvement is a spinal instrument (preferably, a bone screw driver) having a flexible shaft comprising a plurality of interlocking segments carried on a malleable core rod. The flexible shaft allows a screwdriver handle to be perfectly in-line with the cage inserter if desired, while still taking advantage of the tactile feel and torque transmission of the flex segment in its bent position. Accordingly, a surgeon can limit the amount of retraction and keep the driver handle close to the inserter without having to overcome the forces of the flexible segments' natural straight configuration. | 12-31-2015 |
20160022325 | ORTHOPEDIC PLATE BLOCKING ASSEMBLY - In an exemplary embodiment, the present invention provides an orthopedic plate blocking assembly that can be used for the fixation or fastening of an orthopedic plate to bone tissue. In particular, the present invention, in one embodiment, provides an orthopedic plate having a plurality of cavities where each cavity is configured and dimensioned to receive a bone anchoring member. The orthopedic plate further provides a blocking mechanism having a plurality of blocking members that block the bone anchoring members to prevent the bone anchoring members from “backing out” of cavities once the bone anchoring members are finally seated in the cavities. | 01-28-2016 |
20160074079 | OSTEOTOMY DEVICE, IN PARTICULAR FOR PERFORMING EXTREME SCARF OSTEOTOMY IN THE TREATMENT OF SEVERE HALLUX VALGUS - An extreme movement osteotomy device includes an attachment plate suitable for being locked to the cortical substance of the bone to be treated, having a first proximal portion suitable for being attached to the inner cortical substance of the metatarsal diaphysis of the bone, a distal portion suitable for being attached to the outer cortical substance, next to the epiphysis of the metatarsus, and a central portion connecting the proximal and distal portions, each one of the proximal and distal portions of the plate being provided with at least one hole and orthopaedic screws to pass therethrough; and a proximal intramedullary support system having a shank with a foam tip extending from the end of the proximal portion of the plate. | 03-17-2016 |
20160074081 | Bone Plating System - The present invention relates to a bone plating system and method for fracture fixation of bone. The bone plating system includes a bone plate, at least one locking screw, and at least one non-locking screw. The bone plate has locking holes with threads and non-locking holes. The locking screws have a shaft with a thread for engaging bone and a head with a thread configured and dimensioned to mate with the thread of the locking holes. The non-locking screws have a thread for engaging bone and a non-threaded head. Both the locking and non-locking screws remain seated in their respective holes for substantially as long as the bone plate is implanted. The non-locking screws compress the bone plate against the bone and hold fracture reduction while the locking screws are secured to the plate at a fixed angular relationship. The mixed fixation achieved by this bone plating system and method is particularly useful for treatment of per-articular fractures. | 03-17-2016 |
20160089191 | BONE PLATE LOCKING MECHANISM - A bone plate locking mechanism and methods for utilizing same are disclosed. A bone plate in accordance with the present invention includes a bone screw hole having a plurality of first lips and a plurality of second lips. The first lips are closer to the upper surface than the second lips and the first and second lips are offset around the bone screw hole. | 03-31-2016 |

20220133373 | ENHANCED ORTHOPEDIC SCREW - A subtalar arthroereisis screw may have a head and a body with a distal tip, a shank extending from the head to the distal tip, and a screw thread extending along the shank. The shank may have a leading end proximate the distal tip and a trailing end proximate the head. The screw thread may be continuously variable between a first pitch relatively closer to the trailing end, and a second pitch, larger than the first pitch, relatively closer to the leading end. The head may have a receiving end that is connectable to a tool to facilitate rotation of the head with the tool during implantation of the subtalar arthroereisis screw. The screw thread may taper continuously from a first major diameter at the trailing end, to a second major diameter, smaller than the first major diameter, and may have a plurality of notches distributed along its length. | 05-05-2022 |
