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.

Geared cam expandable interbody implant and method of implanting same

Embodiments of the present disclosure include in-situ formed or in-situ-manufactured expandable cages, expandable implants, and additive-manufacturing systems for printing spinal implants in-situ, and methods for printing the same. Some embodiments may include a robotic subsystem including scanning and imaging equipment configured to scan a patient's anatomy. Some embodiments may further include an armature having a dispensing component configured to dispense at least one printing material and a controller. The controller may be configured to control the scanning and imaging equipment to determine a target alignment of a patient's spine, and develop in-situ-forming instructions including an in-situ relocation plan. In some embodiments, the in-situ-forming instructions may be based on the target alignment of the patient's spine and an interbody access space which may only partially provide access to a disc space between adjacent vertebra of the patients spine. The controller may execute the in-situ-forming instructions to form an interbody cage.

In-situ additive expandable implants

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.

Expandable spinal implant system and method of using same

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.

Surgical instrument and method

Systems and methods for setting an implant are provided. A robotic arm may automatically orient a screw head to a predetermined orientation relative to a pedicle screw. The screw head may be pivotably coupled to the pedicle screw. The robotic arm may lock the screw head in the predetermined position.

An expandable implant may include a superior endplate and an inferior endplate hingedly coupled together. 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. The implant may further include a proximal plate having a superior engagement surface and an inferior engagement surface. At least one shim may be disposed within the at least one tracks of the superior endplate and interior endplate, and the at least one shim may define an angle of inclination between the superior endplate and interior endplate. The at least one shim may be insert between the superior and inferior endplates to effectuate expansion and angulation. In various embodiments, the superior endplate may be supported by the superior engagement surface and the inferior endplate may be supported by inferior engagement surface.

Interbody implant with adjusting shims

A rhomboid shaped spinal implant may include a proximal surface that extends from a first lower end to a first upper end thereof a first distance, and a distal surface that extends from a second lower end to a second upper end thereof a second distance. The implant may include a superior surface that extends from the first upper end of the proximal surface to the second upper end of the distal surface a third distance, and an inferior surface that extends from the first lower end of the proximal surface to the second lower end of the distal surface a fourth distance. In various embodiments, the first distance is greater than the second distance, and the third distance is less than the fourth distance. In some embodiments, at least one bone screw aperture defines a trajectory extending in a direction substantially perpendicular to the superior and/or inferior surface.

Rhomboid shaped implants

A telescoping access cannula comprising: an outer tube; an inner tube carried by the outer tube, the inner tube being coaxial with the outer tube and longitudinally movable relative to the outer tube; and a rotatable member carried by the outer tube and connected to the inner tube, wherein rotation of the rotatable member causes longitudinal movement of the inner tube relative to the outer tube.

Method and apparatus for accessing the interior of a hip joint, including the provision and use of a novel telescoping access cannula and a novel telescoping obturator

An interbody spinal implant including a body portion having a superior side, an inferior side and a lateral side connecting the superior side and the inferior side, at least one of the superior side or the inferior side comprises a bone contacting surface operable to be coupled to an anatomical structure of a patient; and a plurality of uniform features formed in the bone contacting surface, wherein each uniform feature of the plurality of uniform features comprise a planar peak or a round peak and are dimensioned to increase a surface area of the bone contacting surface to promote bone growth.
