摘要： An expandable rod system includes a first rod portion having an internal cavity, a second rod portion sealingly positioned within the internal cavity of the first rod portion and moveable in a first axial direction relative to the first rod portion, and an osmotic chamber for receiving an osmotic agent to facilitate movement of the second rod portion to expand the rod system. The rod system includes a lock assembly engageable with the second rod portion to prevent the second rod portion from moving in a second axial direction. The lock assembly includes a tapered ramped portion and a bearing member that is moveable within the tapered ramped portion such that when compression forces are imparted on the second rod portion, the bearing member becomes wedged in the tapered ramped portion.

摘要： In one embodiment, an expander set includes a first and second expander. The first expander includes an outer surface having a first engagement feature and a groove and the second expander includes an inside surface having a second engagement feature adapted to engage with the first engagement feature. The inside surface of the second expander is shaped to correspond to a portion of the outer surface of the first expander. Additionally, the groove on the outer surface of the first expander is sized and shaped to accommodate a rod of a retraction system such that when the first expander is advanced within the retraction system, the rod remains within the groove. When the first and second expanders are engaged with one another, they define an oblong cross-section.

摘要： In one embodiment, a system (20, 30) includes a retractor (100, 100A, 1113) with a plurality of rods (120, 120A-1-124A-1, 180, 220, 320, 420, 1111A-E) that are cylindrical over part of their length, a light source (230, 330), and a fiber optic cable (229, 329), where at least one rod includes a body with an opening (122, 182, 222, 322) therein. The opening extends from an upper surface (122A, 181B, 222A, 322A) of the rod, through an interior of the rod, and then to a side surface (122B, 182D, 222B, 322B) of the rod located between ends of the rod. The opening is sized so that at least a single monofilament fiber optic cable is disposable therethrough. The system is adapted so that any number of rods may include a fiber optic cable disposed therein and so that the cable may be easily removed or inserted from the rod during use of the retractor.

摘要： A percutaneous spinal cross link system for interconnecting a spinal fusion construct on one side of the longitudinal axis of the spine with a spinal fusion construct on the other side of the longitudinal axis may include a cross bar connected at each end by a respective connector to a respective spinal fusion rod of each of the spinal fusion constructs. The connector may include a rod receiving portion adapted to receive one of the spinal fusion rods and a cross bar receiving portion adapted to receive the cross bar in an orientation generally perpendicular to the spinal fusion rod. A cannula defined by two spaced apart blades may be connected to the connector for defining a minimally invasive pathway through body tissue for introduction of the cross bar to the connector. Other tools for use with the system are also disclosed.

摘要： Disclosed herein is a spinal implant with a solid frame and a porous inner layer. The implant may have a cavity defined by the porous inner layer. The solid frame may have one or more ribs extending from a medial wall to a lateral wall. The thickness of the porous layer may vary relative the thickness of the solid frame at various locations. An inserter to place a spinal implant and a method to perform same are also disclosed.

摘要： In one embodiment, a surgical rigid arm (100, 150, 200, 900) includes a first portion (102, 152, 202, 902), a second portion (103, 153, 203, 903) and a central portion (105, 154, 205, 906), where the central portion is extends between the first and second portions. A first end of the first portion and a second end of the second portion are each attached to a peripheral side (14) of a surgical bed (10, 30) such that the first portion and the second portion extend from the surgical bed in a first direction. The central portion extends substantially horizontally and is positioned over the surgical bed, the central portion being connected to the surgical instrument such that a load from the surgical instrument is distributed across the central portion to the first portion and second portion to provide rigid support for the surgical instrument.

摘要： In one embodiment, an assembly includes a retractor (30, 730, 930) and at least one cylindrical rod (102, 402, 502, 702, 802, 902) attached to the retractor. The rod has a fixed length portion (108, 406, 508, 708, 808, 908) and a spring portion (104, 404, 504, 718, 832, 905). The spring portion of the rod has a longitudinal dimension that changes as a function of loading on the rod. When the rod is in contact with a solid surface such as a bone, it maintains contact with such surface even while changing shape due to loading on the rod. When the assembly includes multiple rods attached to the retractor, both spring-based rods and other types of rods may be used in combination.

摘要： A bone plate having at least one screw hole adapted to receive a bone screw, a blocker having a blocking end for blocking a bone screw from further backout of bone the blocker being predisposed in a blocking position wherein the blocking end at least partially overlaps a portion of the screw hole, the blocker being moveable from the blocking position by contact with the bone screw during insertion of the bone screw into the screw hole, and a blocker fixation element having an open orientation at which the blocker can move from the blocking position and a closed orientation preventing substantial movement of the blocker from the blocking position. The blocker fixation element cannot be moved to the closed orientation unless the screw head passes the blocker, thereby revealing that the blocker fixation element is in position to prevent substantial movement of the blocker.
