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.

An implantable, modular spine stabilization system that allows for multi-level treatment of the spine by providing either rigid fixation or dynamic stabilization at different levels to be treated is provided. This modular spine stabilization system may be configured to span multiple spine levels, and have a curvature that closely matches the curvature of the spine over those multiple levels to be treated. Further, the modular spine stabilization system allows adjustment of the curvature of the overall system such that the system may be adapted for a patient for a customized fit. Instruments are also provided for the assembly and/or implantation of the modular spine stabilization system. The associated instruments may include instruments for adjusting the curvature of the system to the patient, and for implanting the curved system into the patient. The instruments may be configured for implantation of the system in a minimally invasive surgery.

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 distraction device for subcutaneous attachment to vertebrae for correcting curvature of a spine is provided. The distraction device includes a housing that includes a generally hollow interior, a drive system including a drive rod operatively supported in the hollow interior of the housing and a drive element coupled to the drive rod. The drive rod is rotatable within the housing about an axis of rotation and includes a first member a second member. The distraction device includes a first extension arm operatively coupled to the first end of the housing and a second extension arm operatively coupled to the second end of the housing. Rotation of the drive rod, induced by the drive element, causes the first extension arm to move into or out from the opening at the first end of the housing in a first movement direction and the second extension arm to move into or out from the opening at the second end of the housing in a second movement direction to vary a length of the distraction device.

An adjustable rod for spinal corrective surgery is provided that includes a first elongate member and a second elongate member, each having rod portions couplable to one or more bone connecting elements and expansion portions slidably moveable with respect to one another. A plurality of holes in each expansion portion are alignable with one another to choose the length of the adjustable rod and a locking element is inserted through a pair of aligned holes to couple the first and second elongate members and secure or fix the length of the expandable rod.

A method of adjusting a distance between a first surgical rod and a second surgical rod includes providing a surgical rod connector having a housing with first and second ends and a longitudinal passage extending between the first end and the second end. The method also includes positioning the first surgical rod in the first end and positioning the second surgical rod in the second end. The method further includes mounting an anchor mechanism to the surgical rod connector and applying a force on the anchor mechanism and a corresponding force on one of the first and second surgical rods to distract the first and second surgical rods relative to one another.

A spinal device including a variable-length member including a ratchet mechanism that has an operative configuration that allows a change in length of the variable-length member in one direction and prevents a change in length of the variable-length member in an opposite direction, wherein the variable-length member includes polyaxial-joint attachment members for attachment to bone, which permit pivoting movement of the attachment members about more than one pivoting axis, characterized by a force applicator operative to adjust or advance the ratchet mechanism.

A growth rod distraction system a domino having first and second bores provided therein. First and second spinal rods are respectively disposed within the first and second bores for movement relative to the domino. First and second spur gears are disposed within the domino and respectively cooperate with the first and second growth rods such that rotation of the spur gears causes axial movements of the growth rods relative to the domino. The spinal rods may be formed either from a flexible polymer material (such as a PEEK, carbon fiber PEEK, PEAK, or similar medical grade polymer material) or a hybrid combination of such flexible polymer material and a metallic material (such as nitinol or similar medical grade metallic material). The spinal rods can also be used for fusion or non-fusion surgery of the spine to stabilize two or more vertebrae.

A subcutaneous implantable device for aligning a spine having a plurality of vertebrae including a first brace assembly secured to a first vertebra of the spine, a second brace assembly secured to a second vertebra of the spine, a rod secured by the at least two brace assemblies, the rod arranged for limited sliding movement within the at least two brace assemblies, a gear mechanism attached to the rod, a control means attached to the gear mechanism, and a cable fixedly secured to a third vertebra of the spine by an anchor. The third vertebra is located between the first and second vertebrae, and the cable is arranged for pulling the third vertebra towards the rod. A subcutaneous implantable device for gradually lengthening a bone.

A spinal pedicle screw system having the ability to be distracted after the screws (26) are inserted into the pedicle and maintain motion via polyaxial joints (22).
