Abstract: The spinal implant described in the present disclosure utilizes an augmented expanding system to build the desired height spacer in-situ without the need for mechanically expanding devices. An expanding spacer system includes a plurality of implant components configured to mate with each other in the intervertebral disc space and a positioning system used to insert each of the plurality of implant components. Each implant component has a smaller dimension and a larger dimension. The positioning system is used to insert the first component into the disc space with the smaller dimension parallel to the spinal axis, and the positioning system is then used to rotate the first implant component to distract the disc space. Additional implant components are added and rotated to further distract the disc space until a desired height is reached.

The clamp lock is pivotally coupled to the distal portion of the body. The clamp lock is pivotable between secured and unsecured configurations. The tensioning assembly translatable in a direction parallel to the longitudinal axis between proximal and distal position. The tensioning assembly configured to draw a flexible band to tension the flexible band about a bony element.

Abstract: Devices, systems and methods for minimally open orthopedic spine surgery are disclosed. A first flexible screw-based retractor is designed to be coupled to each pedicle screw inserted into adjacent vertebral bodies. A retractor system is provided in which a first retractor blade is mounted to one of the screws and a second movable retractor blade is moved away from the first blade, in a medial direction, to create a working channel through which the disc space may be accessed for passing instruments and implants. Light may be incorporated into the device to illuminate the surgical field. One or all of the retractor blades may be made of a sterilizable plastic or metal and be disposable or reusable.

A cross-coupler may be coupled to each lateral rod, and a longitudinal rod may run along the spine and be coupled to the lateral rods by the cross-couplers. The assembly may be used to correct spinal deformities by manipulating the pedicle screws or cross-couplers to rotate about the lateral rods or the longitudinal rod.

Abstract: In one embodiment, the present disclosure relates to a system that includes a plate holder and an awl. The plate holder has a first end and a second end with an engagement feature at the second end that is engageable with a bone plate. The awl is releasably engaged to the plate holder and includes a locking mechanism adjustable from a first setting to a second setting and a tip. When the locking mechanism is in the first setting, the awl is fixed relative to the plate holder and the tip is disposed within the plate holder. When the locking mechanism is in the second setting, the awl is axially translatable relative to the plate holder such that the tip of the awl extends out of the second end of the plate holder.

Abstract: Disclosed are systems and methods for rapid generation of simulations of a patient's spinal morphology that enable pre-operative viewing of a patient's condition and to assist surgeons in determining the best corrective procedure and with any of the selection, augmentation or manufacture of spinal devices based on the patient specific simulated condition. The simulation is generated by morphing a generic spine model with a three-dimensional curve representation of the patient's particular spinal morphology derived from existing images of the patient's condition. Other anatomical structures in the patient's skeletal system are likewise simulated by morphing a generic normal skeletal model, as applicable, particularly those skeletal entities that are connected directly or indirectly to the spinal column.

Abstract: A spinal fixation device is provided including a modular head assembly and a bone screw. The modular head assembly includes a housing, an anvil, an insert, and a snap ring. The housing defines a proximal surface and an opposite, distal surface, and the proximal and distal surfaces define a throughbore therethrough. The anvil is configured to be slidably received within a portion of the throughbore. The insert defines a proximal surface and an opposite, distal surface, and the distal surface defines a first counterbore therein that terminates at a first annular surface. The first annular surface defines a second counterbore that terminates at a second annular surface. The snap ring is configured to be disposed within the first counterbore of the insert when in a first configuration, and within the second counterbore of the insert when in a second configuration.

Abstract: A driving instrument for adjusting a spinal implant includes an outer shaft having a distal end configured to actuate a proximal adjustment assembly of a spinal implant, and an inner shaft having a distal end configured to actuate a distal adjustment assembly of the spinal implant. The inner shaft is disposed within the outer shaft, with a proximal end of the inner shaft extending proximally from the outer shaft. The proximal end is configured to be rotated such that rotation of the inner shaft results in simultaneous rotation of the inner and outer shafts, with rotation of the outer shaft ceasing at a first value of resistance associated with the proximal adjustment assembly and rotation of the inner shaft ceasing at a second value of resistance associated with the distal adjustment assembly such that cessation of rotation of the inner shaft is independent from cessation of rotation of the outer shaft.
