Abstract: An intramedullary nail system is provided with at least one resilient, elongate nail body configured to extend axially along a medullary bone cavity, and at least one bone anchor. The bone anchor includes a distal bone engagement portion configured to secure the anchor to a bone, a proximal nail engagement portion configured to receive a portion of the nail body therethrough, and a tightening mechanism configured to move from a movable state in which the nail body may slide axially and rotate through the engagement portion and a fixed state in which the nail body is prevented from moving relative to the engagement portion. Methods of use and surgical kits are also provided.

Abstract: A system for applying a manipulative force to a target region of a spinal column during a surgical procedure is provided with at least four pedicle screws, at least four elongated levers configured to temporarily engage with the pedicle screws, a linking member configured to link at least two of the elongated levers in a axial direction such that they move in unison, and a cross-linking member configured to link at least two of the elongated levers in a transverse direction such that they move in unison. When the system is assembled, it permits an operator to move the at least four elongated levers in unison to simultaneously rotate the at least four pedicle screws about a spinal column roll axis. Related methods are also provided.

Abstract: A system and method for ameliorating spinal column anomalies, such as scoliosis, includes bone screws which are to be implanted in the pedicle region(s) of individual to-be-derotated vertebrae and in vertebrae to which balancing forces must be applied as the spinal column is derotated en mass to achieve an over-all correction of the condition. A pedicle screw cluster derotation tool simultaneously engages multiple pedicle screws and transmits rotative forces to multiple vertebrae to effect a whole-spine correction. Precontoured spinal rods are engaged post-derotation to secure the correction.

Abstract: A system and method for ameliorating spinal column anomalies, such as scoliosis, while accommodating growth of juvenile patients, which include pedicle screws and an extendable telescopic spinal rod of non-circular cross section. Each pedicle screw includes spinal rod engagement means of complementary shape to the spinal rod for allowing longitudinal movement of the spinal rod, while resisting axial rotation of the pedicle screw relative to the spinal rod. The spinal rod is thereby allowed to slide longitudinally as attached vertebrae move during growth, while movement in other directions is arrested to preserve a proper orientation of involved vertebrae and to maintain scoliotic correction in three dimensions.

Abstract: A system and method for ameliorating spinal column anomalies, such as scoliosis, while accommodating growth of juvenile patients, includes pedicle screws and a spinal rod of non-circular cross section. Each pedicle screw includes spinal rod engagement mean for achieving a slide-only engagement between each segment of said spinal rod that is respectively engaged with the pedicle screw. Pedicle screws are thereby allowed to slide longitudinally along the spinal rod as attached vertebrae move during growth, while movement in other directions is arrested in order to preserve a proper orientation of involved vertebrae to maintain scoliotic correction in three dimensions.
