A system includes a first pedicle screw, a second pedicle screw, and an adjustable rod having an outer housing coupled to one of the first pedicle screw and the second pedicle screw, the outer housing having a threaded shaft secured to one end thereof extending along an interior portion thereof. The system further includes a hollow magnetic assembly disposed within the outer housing and having a magnetic element disposed therein, the hollow magnetic assembly having an internal threaded surface engaged with the threaded shaft, the magnetic assembly being coupled to the other of the first pedicle screw and the second pedicle screw, wherein the hollow magnetic assembly rotates in response to an externally applied magnetic field to thereby lengthen or shorten the distance between the first pedicle screw and the second pedicle screw.

A guiding device for fixing flexible blades of spinal implants, which includes a guide device for transfixing flexible blades (1) that constitute the platforms (13) and (14), which have a box-shaped side, where the set of flexible blades (3) crosses and slides, and the other side has a hole (16) for its fixation to the double intermediate connector (5), which bears a pedicle screw (7); said set of flexible blades (3) being formed by two blades (4), overlapped, provided with longitudinal openings (9), through which they are joined by means of a fixing device (11), which allow them to slide over each other.

A coupling device includes a receiving part having a head receiving portion for pivotably receiving a head of a bone anchor and a rod receiving portion defining a recess for receiving the rod, the rod receiving portion having an engagement structure for engaging a locking member to lock the rod in the recess and a first engagement surface different from the engagement structure for engaging an instrument, wherein the first engagement surface is formed away from radially outwardly facing regions of the rod receiving portion, and a locking ring positionable around the head receiving portion and having a second engagement surface for engaging the instrument. The locking ring can assume an insertion position where the head of the bone anchor is insertable into the head receiving portion, and a pre-locking position where the head is prevented from removal from the head receiving portion.

Methods of correcting a spinal deformity, including securing a first rod on a first side of a spine, securing an anchor on a second side of a spine, securing a lateral coupling between the rod and the anchor, translating and/or derotating the spine and securing a second rod on a second side of the spine to provide secondary stabilization to the spine.

A rib fixation plate is provided that is can have one or more locking rib hooks that can translate and rotate independently from one another. The one or more locking rib hooks translate and rotate when in an unlocked conformation and are secured from translation and rotation when in a locked conformation. The plate includes a first end and a second end opposite of the first end, the second end having a housing assembly configured to receive a rod. The rod can be secured to a vertebra with a pedicle screw.

A spinal pedicle screw system includes distractions rods and has the ability to be distracted after the screws are inserted into the pedicle and maintain polyaxial motion via polyaxial joints.

A rib fixation plate is provided that is can have one or more locking rib hooks that can translate and rotate independently from one another. The one or more locking rib hooks translate and rotate when in an unlocked conformation and are secured from translation and rotation when in a locked conformation. The plate includes a first end and a second end opposite of the first end, the second end having a housing assembly configured to receive a rod. The rod can be secured to a vertebra with a pedicle screw.

The low profile screw base comprises a screw base body and a positioning compression ring. An assembly hole penetrates longitudinally through the screw base body. A U-shaped slot for a connecting rod to pass through is provided on an upper portion of the screw base body. The inner wall of the screw base body on the opposite sides of the U-shaped slot is provided with internal threads. Snapping protrusions are formed on the inner wall of the screw base body on the opposite sides of the U-shaped slot below the internal threads. A lower ball socket matched with the round head of the ball screw is arranged in the assembly hole of the lower portion of the screw base body. The positioning compression ring used for compressing the round head is snap fitted above the lower ball socket and below the snapping protrusions (6).

Methods of correcting a spinal deformity, including securing a first rod on a first side of a spine, securing an anchor on a second side of a spine, securing a lateral coupling between the rod and the anchor, translating and derotating the spine to correct the spinal deformity by adjusting an effective length of the lateral coupling, and securing a second rod on a second side of the spine to provide secondary stabilization to the spine.

A vertebral column correction system for correcting a spinal deformity without fusing the joint segments is disclosed. The vertebral column correction system may have first and second vertebral anchors secured to first and second vertebrae. The vertebral column correction system may further comprise one or more intermediate vertebral anchors secured to vertebrae between the first and second vertebrae. A connection member may be disposed within a head portion of the vertebral anchors. At least a portion of the connection member may be a flexible member, such as a flexible cord, configured for tensioning between at least two vertebral anchors for providing a desired amount of tension to apply a correctional force to the spinal column. A spring member, or other tensioning member, may maintain the tension of the connection member.
