A spinal pedicle screw system includes distractions rods and has the ability to be distracted after the screws are inserted into the pedicle and maintain polyaxial motion via polyaxial joints.

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.

A non-intrusive bone anchor for attachment to vertebral laminar processes with a main body which has a lower fixed jaw; a connecting portion to said lower fixed jaw, a bore hole providing basis for an axis from one side of said connecting portion to the other, and a threaded two ring clamp where each ring has an inner threaded surface with a threaded axis; An externally threaded shaft with a first and second end, where said first end has an internal torquing indent and a portion adjacent thereto for a locking mechanism to engage the outer portion of the clamping ring and said first end has a fixation protuberance. An upper jaw that cooperates with said externally threaded shaft and engages bone between said upper jaw and said lower fizzed jaw forming a diagonal across a clamped bone body; and an inter-anchor connector comprising an axis with a first connector end and a second connector end where said first connector end has a rod portion and said second end has a tulip rod fixer portion.

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. Examples of the implantable growing rod assembly include a smart growing system, and an autonomous growing rod system.

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.

A bone fixation system where an alignment rod is engaged by pedicle screws. The alignment rod has sections of buttress thread. Each pedicle screw has a threaded shaft that supports a slotted receptacle. A set screw threads into the slotted receptacle. A locking plate is interposed between the set screw and the alignment rod. The locking plate contains protrusions that engage the sections of buttress thread on the alignment rod. The threaded shaft of the pedicle screw has an upper section and a lower section. A threaded connecting rod interconnects the sections. The upper section, lower section and threaded connecting rod all have external threads of the same thread pitch.

Active compression devices, methods of assembly and methods of use are disclosed. A bone fixation device may include a first member, a second member shaped to engage the first member, and at least one deformable member. A bone fusion device including a female member with a proximal and distal end, a male member with a proximal and distal end, and at least one elastic element positioned between the female member and the male member. A bone plating device including a first member, a second member shaped to engage the first member, and at least one deformable member positioned between the first member and the second member. Methods of assembling and using the bone fixation devices, bone fusion devices, and bone plating devices are also disclosed.

A crosslink is provided for securing orthopedic implants, such as facet joint replacement implants, together. The crosslink has a pair of implant coupling components, a pair of rod coupling components, a rod, and a pair of fasteners. Each facet joint implant may include a semicylindrical interface received in a resilient member of the corresponding implant coupling component to permit relative cephalad/caudal adjustment between the crosslink and the implants. The resilient members grip the semicylindrical interface of the implant to enable at least temporary attachment of the implant coupling components to the implants independently of the rod. Clocking features on the semicylindrical interfaces and on the interfacing areas of the implant coupling components and rod coupling components may limit assembly of the crosslink to discrete relative orientations and prevent play after assembly. The fasteners secure the rod coupling components to the rod at the desired positions along the rod.
