Abstract: A method for growing a channeled spinal implant in situ, using a surgical additive-manufacturing system having a dispensing component, and implants formed thereby. The method can include positioning the dispensing component at least partially within an interbody space, between a first patient vertebra and a second patient vertebra, and maneuvering, in an applying step, the dispensing component within the interbody space and depositing, by the dispensing component, printing material on or adjacent the first vertebra. The applying step includes maneuvering the dispensing component and applying the printing material selectively to form an outer surface of the implant having a channel opening and to form an interior of the implant having at least one elongate channel extending to the opening.

Abstract: A spinal implant includes an outer body extending along an axis between opposite first and second ends. The outer body defines a bore and a first thread. An inner shaft includes opposite first and second ends. The second end of the inner shaft is positioned in the bore. The inner shaft includes a second thread that mates with the first thread. The second thread includes a series of gear teeth. An end plate is coupled to the first end of the inner shaft. A driver includes a gear configured to engage the gear teeth such that rotation of the driver relative to the outer body rotates the inner shaft relative to the outer body to translate the inner shaft relative to the outer body along the longitudinal axis. Systems and methods are disclosed.

Abstract: A method for treating a spine comprises the steps of: inserting a surgical instrument into a tissue cavity, the surgical instrument including an image guide oriented relative to a sensor to communicate a signal representative of a position of the surgical instrument relative to the tissue cavity; displaying a selected configuration with a distal end of the surgical instrument in the tissue cavity; tracking movement of the selected configuration in the tissue cavity with a tracking device that communicates with a processor to generate data for display of the movement; and determining a volume of the tissue cavity based on the data.

Abstract: An expandable spinal implant includes a distal projection extending from only one side of the implant, ending in an anterior tip, the anterior portion and anterior tip defining an elongated distal end hook, which is wider than the proximal end. The distal end hook rotates around the spinal cord, aligning the implant with a desired pathway, then inserts into place in the disc space between the vertebrae. The elongated widened distal end hook provides a TLIF approach, distributes loads, provides anterior rim engagement, and creates lordosis.

Abstract: An expandable implant may include a superior endplate and an inferior endplate. The superior endplate may have at least one track extending in a proximal-to-distal direction and an inferior endplate may have at least one track extending in the proximal-to-distal direction. An adjusting shim may be disposed within the at least one track to adjust a spacing and angle of inclination of the implant. Some embodiments may include a plurality of tracks for adjusting a spacing and an angle of inclination between the superior endplate and the inferior endplate. Some embodiments may be configured to adjust an orientation of the implant relative to a disc space in both the sagittal plane and the coronal plane. Various embodiments disclosed herein may be used in an Anterior lumbar interbody fusion (ALIF), Transforaminal lumbar interbody fusion (TLIF), or a lateral Lumbar Interbody Fusion (LLIF) procedure, for example.

Abstract: A geared cam expandable spinal implant. Rotational motion of a rotating portion is translated into linear motion of a yoke, which moves geared cams at the distal end of the implant to mate with, and walk along, teeth of corresponding racks. The walking of the gear cam teeth along the rack teeth creates a regular rate of implant expansion, reduces initial excessive expansion force applied to the implant, and provides fine adjustment of the expansion rate and force.

Abstract: A surgical instrument comprises a member defining a longitudinal axis and being connectable with a spinal implant. A handle is connected with the member. An image guide is connected with the member for orientation relative to a sensor to communicate a signal representative of a position of the spinal implant. The image guide is rotatable about the axis relative to the member and is disposable in at least one fixed position with the member. Systems, implants, spinal constructs and methods are disclosed.

Abstract: Spinal implant trials are provided having various configurations and sizes that aid the selection of spinal implants having similar configurations and sizes. A surgeon during surgery can insert various configurations and sizes of the spinal implant trials into a disc space between two adjacent vertebral bodies of a patient to enable the selection of a spinal implant configured and sized to fit the patient's disc space. Fluoroscopic images can be used in aiding the selection of an appropriately configured and sized spinal implant corresponding to one of the spinal implant trials. The spinal implant trials include features that reveal on the fluoroscopic images whether the spinal implant trials are properly oriented and positioned in the disc space. As such, the selection of the configuration and size of the spinal implants can be made after it is determined that the spinal implant trials are properly oriented and positioned within the disc space.
