Spinal fixation systems including a member, a first attachment portion, a second attachment portion, and an intermediate portion. The first attachment portion is attached at a superior end of the member and includes a first opening. The second attachment portion is attached at an inferior end of the member and includes a second opening. The intermediate portion connects the first and second attachment portions. The spinal fixation systems may also include a relief in at least one of the first opening and the second opening. The systems may also include a third attachment portion with a third opening and an intermediate portion with a first and a second elastic mechanism. The first elastic mechanism connects the first and third attachment portions and the second elastic mechanism connects the third and second attachment portions. Surgical methods for inserting the spinal fixation systems in a patient are also disclosed.

A segmented rod assembly for aligning a spine having 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 slidingly secured to a first vertebra of the spine, a second segment arranged to be fixedly secured to a second vertebra of the spine, and a third segment arranged between the first and second segments to be connected to a third vertebra of the spine, a tensioning member arranged within the plurality of segments, the tensioning member having a first end secured to the first segment and a second end.

Embodiments herein are generally directed to extendable rods for use in orthopedic assemblies. In some embodiments, these implants may be used in conjunction with procedures to treat spinal deformities, including, but not limited to, early onset scoliosis.

A spinal distraction system including a bearing connector fastened to a fixated rod and a sliding rod, wherein the sliding rod includes a spring and a stop ring is disclosed. A method of distracting vertebrae is also disclosed.

A self-actuating growing rod systems for the correction of orthopedic deformities. The system comprises at least one static rod, at least one growth rod, at least one sealing component, at least one fluid reservoir, at least one injection port and at least one pressure compensating mechanism which is adapted to cause net elongation of the growth rod. The system of the present disclosure is implanted onto the bony anatomy after bringing the deformed bony anatomy to the expected position. The system of the present disclosure is then surgically implanted onto the corrected bony anatomy. As growth occurs, the system of the present disclosure distracts; thereby enabling growth and maintaining the deformity correction.

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 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 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 segmented rod assembly for aligning a spine having 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 slidingly secured to a first vertebra of the spine, a second segment arranged to be fixedly secured to a second vertebra of the spine, and a third segment arranged between the first and second segments to be connected to a third vertebra of the spine, a tensioning member arranged within the plurality of segments, the tensioning member having a first end secured to the first segment and a second end.
