Abstract: Methods for growing spinal implants in situ using a surgical additive-manufacturing system. In one aspect, the method includes positioning a dispenser at least partially within an interbody space, between a first patient vertebra and a second patient vertebra. The method includes maneuvering the dispensing component within the space to deposit printing material forming an interbody implant part, positioning the dispensing component adjacent the vertebrae, and maneuvering the dispenser adjacent the vertebrae to deposit printing material on an exterior surface of each vertebrae and in contact with the interbody implant part forming an extrabody implant part connected to the interbody implant part and vertebrae, yielding the spinal implant grown in situ connecting the first vertebra to the second vertebra. The extrabody part can be printed around anchors affixed to the vertebrae, and the anchors may be printed in the process.

Abstract: A surgical instrument includes at least one blade defining a longitudinal axis and includes a distal member. An actuator is engageable with the member to rotate the member relative to the longitudinal axis to space tissue adjacent a surgical site. Surgical systems, constructs, implants, and methods are disclosed.

Abstract: A build-plate with integrally-formed spinal implant constructs and a method used in forming spinal implant constructs on the build plate and machining the spinal implant constructs formed on the build plate to manufacture spinal implants is provided. The spinal implant constructs can be formed via additive manufacturing processes by adding material to an upper surface of the build plate, and then the spinal implant constructs can be subjected to subtractive manufacturing processes to form the spinal implants.

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. Spikes, pivotally mounted on the yoke, pivot outward as the implant expands, to a fully-deployed position into engagement with surfaces of adjacent vertebral bodies. The engagement between the deployed spikes and the vertebral bodies prevents inadvertent backout of the expanded implant.

Abstract: A device for mixing and dispensing bone material is provided. The device comprises a tubular member having an interior surface configured to receive bone material and a fluid to mix the bone material disposed within the tubular member. The tubular member is flexible and has a proximal opening configured to slidably receive a plunger, and a distal opening configured to dispense a mixed bone material from the interior surface of the tubular member. The plunger is less flexible than the tubular member. Methods of mixing and dispensing bone material are also provided.
