The present invention generally relates to methods and devices for treatment of spinal deformity, and in particular to the utilization of at least one implant to either maintain the position of at least one vertebra of a patient to prevent increase in abnormal spinal curvature, to slow progression of abnormal curvature, or to impose at least one corrective displacement and/or rotation on at least one vertebra of a patient so as to incrementally correct abnormal spinal curvature.

Spinal correction surgical techniques and methodologies for correction of scoliosis using non fusion anterior scoliosis correction, including soft tissue releases, unique correction techniques such as de-rotation, and unique single and dual anchor screw/cord applications.

An anchoring device (40) for anchoring one or more sub-laminar bands or tapes (60a, 60b) to a pedicle screw (30), the device (40) comprising: a first portion (41) configured for attachment to at least a base portion (32 L) of a head portion (32) of the pedicle screw (32); and at least one second portion (46a, 46b) for anchoring thereto a or a respective sub-laminar band or tape (60a, 60b); wherein the first portion (41) includes first interengagement means (42Na, 42 Nb) for interengagement with corresponding notches or recesses (32Na, 32 Nb) in the head portion (32) of the pedicle screw (32) to effect the said attachment of the first portion (41) of the anchoring device (40) thereto.

A spinal construct comprises a first member configured for attachment to a first portion of vertebral tissue that defines a longitudinal axis. A second member is configured for attachment to a second portion of the vertebral tissue such that the second portion is axially movable relative to the second member and sagittal movement of the second member relative to the second portion is resisted and/or prevented. Systems and methods are disclosed.

A pivotal bone anchor assembly includes a shank with a head and an anchor portion, and a receiver with a channel for receiving a rod and a lower portion of an axial bore for receiving the shank head, with the axial bore including a stop structure and a downwardly-facing surface beneath a helically wound thread. The assembly also includes an insert having an upwardly-facing seat, a lower surface for engaging the shank head, a side structure for engaging the stop structure, and an upwardly-facing surface positioned radially outward from the upwardly-facing seat, with the insert being installed into the axial bore in a first angular position. Subsequent rotation of the insert within the axial bore moves the upwardly-facing surface under the downwardly-facing surface to inhibit upward movement of the insert within the axial bore, with further rotation being inhibited by the side structure coming into engagement with the stop structure.

A spinal fixation construct for aligning vertebral bodies includes a bone screw, a spinal rod, a flexible member, and a fixation member. The spinal rod is disposed within a saddle portion of a housing of the bone screw, and includes an elongated body having a first end and a second end. The spinal rod is formed from a first material having a first modulus of elasticity. The flexible member is coupled to the spinal rod, and includes an elongated body having a first end portion and a second end portion. The flexible member is formed from a second material having a second modulus of elasticity that is different from the first modulus of elasticity. The fixation member includes a threaded body portion and a head portion defining a hole therethrough. A portion of the flexible member extends through the hole of the head portion.

A spinal management system includes a stabilizing member adapted to extend substantially longitudinally along a target region of a spine tending to exhibit a defective curvature and a set of stabilizing anchors adapted for fixation to vertebrae and to receive the stabilizing member to secure the stabilizing member against substantial transverse translation relative to the vertebrae. The system also includes a first correction anchor adapted for fixation to a vertebra, a second correction anchor adapted for fixation to a vertebra, and a connection between the stabilizing member and the first correction anchor and between the first and second correction anchors adapted such that when the connection is tensioned a compressive force is selectively exerted between the first and second correction anchors.

A method of inserting a spinal stabilization system into a patient generally comprises inserting a first positioning tool through a first location on a patient's skin and along a path generally toward a first vertebral anchor, coupling an end of the first positioning tool to the first vertebral anchor, positioning at least a portion of a delivery device over a connecting element, and inserting the delivery device and the connecting element through the patient's skin at the first location and along at least a portion of the first positioning tool. The first positioning tool is configured to facilitate directing the delivery device and connecting element generally toward a second vertebral anchor within the patient's body.

One or more sutures can be used in spinal applications to hold an intradiscal device in place between two vertebrae or repair a defect in the soft tissue of the spine, such as the annulus fibrosis or the dura. Tension can also be applied to the sutures to stabilize a spinal segment having an intradiscal device to prevent or minimize excessive spinal extension, lateral bending, and axial rotation of the spinal segment. Anchors are placed in two adjacent vertebrae and sutures are passed through each anchor. The sutures can be passed through portions of the intradiscal device. Alternatively, the sutures can be passed through a mesh patch which is held against the vertebrae to hold the intradiscal device in place. Tension is applied to the first and second ends of the sutures and the sutures are welded together. The sutures can be welded in a cross-braced arrangement minimize or prevent extension, lateral bending, and rotation of the spinal segment. For example, the sutures can be welded in a diagonal pattern, a horizontal pattern, a vertical pattern or any combination thereof across the adjacent vertebrae.
