摘要： A surgical instrument includes a first member having an inner surface and an outer surface. A second member has an inner surface and an outer surface. The outer surfaces are engageable with tissue adjacent a spine that defines a longitudinal axis. The members are relatively movable between a first configuration and a second configuration to space the tissue. In the first configuration, the members are disposable between a first position such that the inner surfaces define a substantially oval cavity that defines a major axis substantially aligned with the longitudinal axis and a second position such that the major axis is rotated relative to the longitudinal axis to space psoas tissue. Systems and methods are disclosed.

摘要： An expandable interbody implant adapted for insertion at least into a disc space, between two adjacent vertebrae of a spine. An upper member and a lower member are pivotally connected at least by a drive link. A bone graft storage portion packed with a selected volume of bone growth material. A translational wall is provided between the bone graft storage portion and a trailing end of the implant. An actuator engages the bone graft storage portion, pushing it forward into engagement with the drive link, which pivots upward, moving the upper member upward away from the lower member. Upward movement of the upper member raises the translational wall to a position to assist in retention of the selected volume bone graft material within the hollow portion of the bone graft storage portion. Upward rotation of the drive link brings a face thereof into contact with a front of the bone graft storage portion, thereby retaining near constant volume of the bone graft material.

摘要： A surgical implant and a method for the making the surgical implant is provided. The surgical implant includes various granules incorporated into an upper surface and a lower surface of a body portion thereof. The granules can be pressed into the upper surface and the lower surface via physical force using at least one mold portion. The physical force applied by the at least one mold portion can deform and/or extrude the upper surface and the lower surface to impregnate these surfaces with the granules. The granules can provide the implant with bioresorbable and/or mechanically-reinforced properties.

摘要： A spinal implant comprises an implant body extending between an anterior surface and a posterior surface and includes a first vertebral engaging surface and a second vertebral engaging surface. The implant body includes an inner surface that defines at least one cavity that is oriented to implant a fastener oblique relative to a lateral axis of a subject body and adjacent an intervertebral space of the subject body. At least one indicia is disposed with the implant body to facilitate orientation of the implant body with the subject body. Systems and methods are disclosed.

摘要： A spinal implant comprises an implant body extending between an anterior surface and a posterior surface, and including a first vertebral engaging surface and a second vertebral engaging surface. The implant body includes an inner surface that defines at least a first cavity and a second cavity. The cavities are oriented to implant fasteners in alignment with an oblique surgical pathway relative to a bilateral axis of a subject body and adjacent an anterior portion of an intervertebral space of the subject body. Systems and methods are disclosed.

摘要： 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.

摘要： A pivoting wedge expandable spinal implant. An upper portion and a lower portion are pivotally connected together. The implant, in a collapsed position, is inserted into a disc space. A driving screw engages and applies a force to a pushing portion, driving the pushing portion toward the implant's distal end. The pushing portion engages and drives a wedge toward the implant's distal end. The wedge pivots upward against an inner surface of the lower portion. The wedge continues to pivot along an inner surface of the upper portion, translating the force to the upper portion, pivoting and expanding the upper portion to an expanded position.
