Patent number: 11857231Abstract: In one form, a bone compression device is provided having a shape-retentive bone plate with an initial, unflexed configuration and a flexed configuration. The bone plate may be shifted to the flexed configuration and secured to bones using bone screws of the bone compression device. Once the bone plate has been secured to the bones, the bone plate returns toward its unflexed configuration which compresses the bones.Type: GrantFiled: January 26, 2021Date of Patent: January 2, 2024Assignee: Pioneer Surgical Technology, Inc.Inventor: Matthew P. Gephart

Patent number: 11857232Abstract: A fracture fixation system includes a plate having a laterally extending bore passing therethrough and configured to receive a first wire when the plate is placed in contact with a bone. The plate has a recess for receiving and securing a first end of a first wire, and includes an entry hole and an exit hole to at opposite ends of a first bore to allow the first wire to pass through the plate. A screw is configured to capture said the wire in the first bore to maintain a desired tension on the first wire.Type: GrantFiled: February 19, 2021Date of Patent: January 2, 2024Assignee: MEDARTIS AGInventors: Lon S. Weiner, John R. Pepper, Stuart D. Katchis, Ryan Schlotterback

Patent number: 11857233Abstract: A bone screw comprises a shaft defining a longitudinal axis and a minor diameter. The shaft including a core having an angled surface relative to the axis. The angled surface extending from the minor diameter adjacent a proximal portion of the shaft to a distal portion of the shaft, and a wall disposed about the angled surface. The wall including at least one thread having an external thread form. In some embodiments, systems, spinal constructs, surgical instruments and methods are disclosed.Type: GrantFiled: December 7, 2021Date of Patent: January 2, 2024Assignee: Warsaw Orthopedic, Inc.Inventors: Dale A.

Patent number: 11857234Abstract: An orthopaedic bone stabilisation device includes an elongate and integrally formed body having a length extending between proximal and distal ends. The elongate body includes a first threaded section having a head at the proximal end, the head configured to interface with a driver, the threaded section having external threads extending along a length of the first threaded section. The first threaded section extends between the proximal end and a first location of the elongate body. The first threaded section tapers from the proximal end to the first location such that the outer thread diameter of the first section gradually decreases from the proximal end to the first location of the elongate body. The device further includes a second threaded section having external threads, a length, and a substantially uniform thread diameter, and extends between the distal end of the elongate body and a second location of the elongate body.Type: GrantFiled: December 10, 2020Date of Patent: January 2, 2024Assignee: FIELD ORTHOPAEDICS PTY LTDInventors: Shanthan Pather, Jarred Bairstow

Patent number: 11857235Abstract: A differential compression bone screw and a method are provided for compressing adjacent bone portions together to encourage bone fusion. The compression bone screw is comprised of a head portion and a shank. A center hole extends from the head portion to a distal end of the shank. A superior end of the head portion includes a shaped opening that receives a tool for driving the compression bone screw into a hole drilled in a patient's bone. An inferior end of the head portion includes barbs that engage with surrounding bone tissue. A smooth portion of the shank is disposed between proximal threads and distal threads that rotatably engage within the hole in the patient's bone. A thread pitch of the distal threads is greater than a thread pitch of the proximal threads, such that the compression bone screw comprises a differential pitch configured to compress the adjacent bone portions.Type: GrantFiled: May 13, 2021Date of Patent: January 2, 2024Assignee: In2Bones USA, LLCInventors: Kevin E. Varner, Keith A. Heier, Travis W. Hanson, Casey M. Chambers, Rebecca Hawkins Wahl
