LATERAL INSERTION SPINAL IMPLANT
The present disclosure relates to a spinal implant. The spinal implant may be used for lateral insertion into an intervertebral disc space. For example, the spinal implant may include a spacer body to which a plate is fixed. The intervertebral spacer body may include a pair of opposite sides having a pyramid-shaped teeth to fuse to bone. The plate defines at least one upper and lower borehole that each receives a screw. Each screw attaches the plate to a vertebral body between which the intervertebral spacer body is inserted. The boreholes may include locking threads that are adapted to lock the screws into place by engaging complementary locking threads of head of the screw.
Tissue Integration Devices And Methods Of Making The Same
One aspect of the present disclosure relates to a tissue integration device. The tissue integration device can be produced by forming a polymer mixture into a shape. The polymer mixture can include a polymer resin and a growth-promoting medium. Next, at least one polymer forming the polymer resin can be oriented in at least one direction. The shaped polymeric material can then be formed into the tissue integration device.
MEDIAL TWIST ANCHOR
Disclosed are devices, methods and/or systems for securing tissue to bone, including a suture anchor implant having a body with an internal cavity and one or more helical cutting flutes positioned on an external surface of the body which direct at least a portion of the cut bony material into the internal cavity as the body is rotated into bone.
Patient-specific bridging plates
Disclosed herein are a bone plating system and a method for utilizing the same. The bone plating system may include first and second bone plates in contact with respective first and second bones, a cross-connector, a cutting guide and a targeter device. The cross-connector may have a first end and an opposite second extending along a longitudinal axis from the first bone plate to the second bone plate. The cutting guide may have an elongate body placed on one of the first or second bones. The targeter device may have a drill guide to align the cross-connector with the first and second bone plates. A method for fixing the bone plating system to the first and second bone may include using the targeter device.
Bone Screw Fixation System
A bone screw fixation system includes a bone screw body having a screw head at one end of the screw and a screw tip at an opposite end of the screw, the screw head having an internal complex geometric shaped drive and internal threads within the screw head; and a screw inserter compatible with the screw head and having a complex geometric shaped drive configured to matingly engage the internal complex geometric shaped drive of the screw head and a threaded tip configured to thread into the internal threads of the screw head.
BONE IMPLANT AND METHOD OF CONTROLLING THE BONE IMPLANT
The combination of: a) an implant having a body with a leading end and a trailing end and external threads extending around a lengthwise axis, the body having an axial through passage and configured to be directed into a bone passage whereby upon turning the body in a first direction around the lengthwise axis, the external threads engage a surface bounding the bone passage and cause the implant to be advanced in an assembly direction into an operative position; and b) a removal tool with a first component that is configured to be engaged with the body with the implant in the operative position in such a manner that the body will follow movement of the first component as the first component is: a) turned in a direction opposite to the first direction; and b) drawn in a direction oppositely to the assembly direction to thereby allow the implant to be separated from the bone.
BONE SCREW
A bone screw includes a shank having a longitudinal axis, a tip configured to be inserted first into bone, a core, and a thread with a plurality of turns winding in a helix around at least part of the core to engage bone. The thread has a lower flank and an upper flank, wherein for a first section of the thread, the upper and lower flanks form a first angle for at least one full turn, and wherein for a second section of the thread, the upper and lower flanks form a second angle for at least one full turn that is greater than the first angle. An outer diameter of the second section adjacent to the first section is at least as wide as an outer diameter of the first section adjacent to the second section.
Bone screw and method of using same
A bone screw and method of using the same for immobilizing a joint, the bone screw including a screw head, an elongate shaft having a threaded outer wall and a helically-shaped slot extending through the outer wall and longitudinally along the shaft. The slot extends longitudinally along a middle section of the threaded outer wall, terminating short of the proximal and distal ends of the shaft, or the slot extends through the distal end and/or to the proximal end of the shaft immediately adjacent to the screw head. The slot includes a cutting edge that is arranged to engage bone when the screw advances therethrough for cutting away a portion of the bone. A reservoir is located within the elongate shaft for collecting bone that is cut away or removed by the cutting edge.
PIVOTAL BONE ANCHOR ASSEMBLY WITH NON-PIVOTING, NON-ROTATABLE RETAINER
A pivotal bone anchor assembly includes a shank having a shank head with a partial spherical shape at a proximal end and an anchor portion opposite the shank head for fixation to the bone of a patient. The assembly also includes a receiver having an upper portion defining a channel for receiving an elongate rod and a base defining a cavity in communication with the channel and with a bottom surface of the receiver through a distal opening. The assembly further includes a retainer positionable into non-rotatable and non-pivotal engagement with an inner surface of the cavity prior to the shank head being received within the cavity, with the retainer having a central opening configured to receive and capture the shank head within the cavity while allowing for pivotal motion between the shank and the receiver in at least one plane, and with a lower portion of the retainer extending below the bottom surface of the receiver.
CLAW-SHAPED PEDICLE SCREW FASTENER FOR OSTEOPOROSIS
The disclosure discloses a claw-shaped pedicle screw fastener for osteoporosis, including an inner screw plug and an outer screw; the outer screw includes an outer nut and an outer screw stem, a through hole is defined in and penetrates through the outer nut and the outer screw stem, the outer screw stem has a thread segment, a claw-shaped segment, and a conical segment that are provided on outside of the outer screw stem; the claw-shaped segment is made of deformable metal; the inner screw plug includes an inner nut and an inner screw stem, the inner screw stem is inserted into the through hole, and the inner screw stem is threadedly connected to the first inner thread and the second inner thread; the inner screw stem and the second inner thread are reverse thread screws relative to each other.
