A spinal distraction system, according to one aspect, includes an adjustable spinal distraction rod comprising first and second members, the adjustable spinal distraction rod configured for non-invasive elongation of the first and second members. The system includes an anchor rod configured for mounting to a bone of a subject, the anchor rod having one or more spring-biased tabs disposed at one end thereof, and a connector having first end and a second end, the first end having a receiving cup configured for detachable mounting on the anchor rod, wherein the one or more spring-biased tabs are configured to engage with an inner surface of the receiving cup, the connector having a second end operatively coupled to an end of a first member and wherein the second member is configured for mounting to a second bone of a subject.

A dynamic longitudinal connecting member assembly includes an anchor member having an integral or otherwise fixed elongate core of circular or non-circular cross-section. The core is pre-tensioned and extends through at least one elastic spacer and at least one outer sleeve. The anchor member and the outer sleeve each attach to at least one bone anchor. In operation, the core is held in tension by the spacer.

A segmented rod assembly for aligning a spine including a plurality of vertebrae, including a rod, including a plurality of segments, the plurality of segments having at least a first segment arranged to be connected to a first vertebra of the spine, the first segment including a first body and at least one tang extending from the first body, and a second segment arranged to be connected to a second vertebra of the spine, the second segment including a second body and at least one channel arranged in the second body, wherein the at least tang is operatively arranged to engage the at least one channel, and at least one tensioning member arranged within the plurality of segments, the at least one tensioning member having a first end secured to the first segment and a second end.

An implantable growing rod assembly adapted to be secured along a length of a spine for treating deformities of the spine. The assembly includes a housing, a fixed rod extending along a longitudinal axis away from the housing, and an expansion rod extendible from the housing along the longitudinal axis. A driver assembly is fixed to the housing and adapted to translate the expansion rod along the longitudinal axis.

A rod system, in particular, for the spine, includes a first rod, a second rod, and a connector for connecting the first rod and the second rod. The connector includes a main body defining a first rod seat configured to hold the first rod in a fixed manner and a second rod seat configured to accommodate a second rod, and a fixation member and a closure member that are interchangeably mountable to the main body. When the fixation member is mounted to the main body, the fixation member is engageable with the portion of the second rod to hold the second rod in a fixed manner relative to the main bod, while when the closure member is mounted to the main body, the closure member is configured to hold the second rod to the main body in a slidable manner.

A dynamic longitudinal connecting member assembly includes an anchor member having an integral or otherwise fixed elongate core of circular or non-circular cross-section. The core is pre-tensioned and extends through at least one elastic spacer and at least one outer sleeve. The anchor member and the outer sleeve each attach to at least one bone anchor. In operation, the core is held in tension by the spacer.

A rod system, in particular, for the spine, includes a first rod, a second rod, and a connector for connecting the first rod and the second rod. The connector includes a main body defining a first rod seat configured to hold the first rod in a fixed manner and a second rod seat configured to accommodate a second rod, and a fixation member and a closure member that are interchangeably mountable to the main body. When the fixation member is mounted to the main body, the fixation member is engageable with the portion of the second rod to hold the second rod in a fixed manner relative to the main bod, while when the closure member is mounted to the main body, the closure member is configured to hold the second rod to the main body in a slidable manner.

A soft dynamic stabilization assembly includes a core, typically in the form of a tensioned cord, at least one pair of bone anchors, a spacer surrounding the core located between the bone anchors, typically, at least one elastic bumper and at least one fixing or blocking member. The core is slidable with respect to at least one of the bone anchors and cooperating spacer.

A spinal stabilization device that can be used to non-invasively correct spacing and curvature between at least two vertebral structures. The spinal stabilization device includes two telescoping tubes wherein ends of the two tubes can have pedicle screws that can be fastened to two or more vertebral bones. The overall length of the spinal stabilization device can be adjusted by moving the inner tube within the outer tube. Both the outer tube and the inner tube have multiple holes for receiving fasteners, wherein a fastener can be inserted through a hole in the outer tube into a hole in the inner tube for interlocking the inner tube and outer tube. The extension of the fastener into the holes and retraction from the holes can be controlled non-invasively from an external source. When the fastener is disengaged, the inner tube and the outer tube can freely move relative to each other, and the positions of the two or more vertebral bones can be non-invasively adjusted by subjecting a person to predefined movements and body posture. Upon achieving the desired positions, the fastener can be engaged to interlock the inner tube and the outer tube.

A rod system, in particular, for the spine, includes a first rod, a second rod, and a connector for connecting the first rod and the second rod. The connector includes a main body defining a first rod seat configured to hold the first rod in a fixed manner and a second rod seat configured to accommodate a second rod, and a fixation member and a closure member that are interchangeably mountable to the main body. When the fixation member is mounted to the main body, the fixation member is engageable with the portion of the second rod to hold the second rod in a fixed manner relative to the main bod, while when the closure member is mounted to the main body, the closure member is configured to hold the second rod to the main body in a slidable manner.
