    摘要: A system includes tubular members removably positionable over a passageway device connected to a connecting element attached to a vertebra. The tubular members may each include a sidewall having an opening positionable adjacent a proximal end of the passageway device when the tubular member is positioned over the passageway device. The tubular members include channels therein to receive respective blades of the passageway devices. One of the tubular members may be a counter torque tube, and another two of the tubular members may be a hinge shaft and a ball shaft, respectively, of a compression and distraction system. The blades of each passageway device may be integrally formed with a cage of the connecting element to form a monolithic blade-screw. The blades of the monolithic blade-screw may be constructed by affixing distal ends of non-threaded blade extensions to proximal ends of threaded reduction portions integrally connected to the cage.

    摘要: In one embodiment, the present disclosure relates to an instrument adapted for use in an anterior to psoas spinal access procedure. The instrument includes a body, a first arm and a second arm. A first rod extends from the first arm at an angle thereto while a second rod extends from the second arm at an angle thereto. Each of the first rod and the second rod include a length with a first portion and a second portion, the first portion having a convex surface perimeter and the second portion having a perimeter different from the first portion and being convex in part. In some embodiments, a kit includes the instrument and a blade adapted for use in conjunction with the instrument in an anterior to psoas spinal access procedure.

    摘要: A bone graft delivery system includes a bone graft injector and an access portal. The access portal may include a handle having a first arm pivotably connected to, and biased away from, a second arm. A ratchet including a pawl may extend from the second arm. A delivery tube may be configured to mate with the first arm and be configured to store a bone graft material therein. A plunger including a shaft and a plunger tip at the distal end thereof may be configured to move through the delivery tube. At least a portion of the shaft may include teeth, the pawl of the ratchet being configured to iteratively contact the teeth. A user may hold the access portal with a first hand and the bone graft injector with a second hand, iteratively squeezing the handle to iteratively eject amounts of bone graft material into a patient.

    摘要: A surgical instrument includes a cannulated body extending along an axis and having a first working end spaced along the axis from a second working end. The surgical instrument may be used with a fenestrated screw assembly, a delivery unit, and an alignment guide wire. The first working end of the surgical instrument is configured to transmit a force to a delivery unit in a direction about the axis and the second working end is configured to transmit a force to a delivery unit in a direction generally transverse to the axis. The first working end may be used to rotate the delivery unit to thereby removably attach the delivery unit to the fenestrated screw assembly. The surgical instrument may be repositioned to engage the second working end with the proximal end of the delivery unit to maintain the rotational position of the delivery unit.

    摘要: A system for percutaneous spinal fusion may include two spaced apart blades connected together by a coupling such that the blades define a percutaneous pathway from a skin incision to an implanted pedicle fastener. The coupling may be c-shaped and may have at least one flexible tab for engaging one or more holes along the length of the blades. If one of the blades becomes disconnected from the pedicle fastener, a supplemental access device may be provided comprising a tubular body having a channel therein for receiving the other of the blades. If both of the blades become disconnected, a supplemental access device may be provided comprising a gripping member received within a locking member. The gripping member may have two legs engageable with the pedicle fastener, and the locking member may move along the gripping member to prevent the legs from disengaging the pedicle fastener.
