    摘要： 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.

    摘要： Interbody implants may be formed by a product by process in which a first metallic frame component having an interconnected superior endplate and an interconnected inferior endplate are formed. In some embodiments, the endplates are interconnected by flexible struts and in others they are interconnected by translating struts. In various embodiments, a polymeric body may be infilled between the superior endplate and inferior endplate by a molding process, e.g., an injection molding process or an overmolding process. In various embodiments, the metallic frame may have a first compressive stiffness, the polymeric body may have a second compressive stiffness, and the first compressive stiffness of the metallic frame may be about 20% to about 80% of the second stiffness of the body. In various embodiments, a sum of the first compressive stiffness of the metallic frame and the second stiffness of the body is about 33,500 N/mm to about 11,500 N/mm.

    摘要： An example expandable interbody device can include a structural body having an upper endplate and a lower endplate, where the endplates are shaped to nest tightly in a closed position. The device can include at least one wedge block and at least one linkage block arranged between the upper and lower endplates of the structural body. The device can include a drive screw threaded through the at least one wedge block and the at least one linkage block. The drive screw can be configured to rotate and drive the at least one wedge block to expand the upper and lower endplates of the structural body from the closed position to an intermediate position. Additionally, the drive screw can be further configured to rotate and drive the at least one linkage block to expand the upper and lower endplates of the structural body from the intermediate position to an open position.

    摘要： The present disclosure relates to an intervertebral fusion cage configured to be inserted between vertebral bodies in a lowest state and improving fixation by bone screws inserted through end plates. The intervertebral fusion cage of the present disclosure may replace intervertebral fusion cages having heights within a given range. Therefore, manufacturers may reduce the number of product groups and the amount of inventory. In addition, because the height of the intervertebral fusion cage of the present disclosure is linearly adjustable according to the distance between vertebral bodies of patients unlike conventional intervertebral fusion cages having heights preset at predetermined intervals, surgery may be performed at an optimal height according to the conditions of patients
