    摘要： An implantable spacer for placement between adjacent spinous processes in a spinal motion segment is provided. The spacer includes a body defining a longitudinal passageway. A first arm and a second arm are connected to the body. Each arm has a pair of extensions and a saddle defining a receiving portion configured for seating a spinous process of a scoliotic spine or a spine with misaligned spinous processes. Each arm has a proximal caming surface and is capable of rotation with respect to the body. An actuator assembly is disposed inside the longitudinal passageway and connected to the body. When advanced, a threaded shaft of the actuator assembly contacts the caming surfaces of arms to rotate them from an undeployed configuration to a deployed configuration. In the deployed configuration, the distracted adjacent spinous processes are seated in the superior and inferior arms of the spacer. Variations adapted for scoliotic curves are provided.

    摘要： A percutaneous and minimally invasive instrument for inserting an interspinous process spacer into a patient is disclosed. The insertion instrument includes a first assembly connected to a handle assembly. The first assembly includes an inner shaft located inside an outer shaft and configured for relative translational motion with respect to the outer shaft. The relative translational motion causes one of the outer or inner shafts to move with respect to the other and thereby deflect at least one prong formed on one of the inner or outer shafts wherein such deflection causes engagement with a juxtapositioned interspinous spacer. The instrument further includes a driving tool configured for removable insertion into a proximal end of a passageway of the instrument. The driving tool has a distal spacer engaging portion configured to engage that part of the spacer requiring activation for deployment of the spacer from at least one undeployed configuration to at least one deployed configuration and vice versa.

    摘要： An implantable spacer for placement between adjacent spinous processes in a spinal motion segment is provided. The spacer includes a body defining a longitudinal passageway. A first arm and a second arm are connected to the body. Each arm has a pair of extensions and a saddle defining a U-shaped configuration for seating a spinous process therein. An actuator assembly is disposed inside the longitudinal passageway and connected to the body. When advanced, the actuator assembly contacts camming surfaces of the arms to rotate them from an undeployed configuration to a deployed configuration. In the deployed configuration, the distracted adjacent spinous processes are seated in the U-shaped portion of the arms providing sufficient distraction to open the neural foramen. An insertion instrument is provided for implanting the interspinous process spacer. The system is configured for implantation through a small percutaneous incision employing minimally invasive techniques.

    摘要： A rod reduction instrument for position a rod relative to a seat of a bone anchor in a spinal implant system is provided. The instrument includes three concentric cannulas with circumferentially aligned rod receiving portions formed therein. One cannula is movable with respect to another to lock and unlock the seat of a bone anchor to the rod reduction instrument. The rod to be reduced is positioned inside at least one of the rod receiving portion. One cannula is moved with respect to another to lock the seat of the bone anchor to the rod reduction instrument. Once locked to the bone anchor, the remaining cannula is moved to reduce the distance between the rod and the seat within at least one of the rod receiving portions. The distance between the rod and the seat is reduced until the rod is position inside the seat. A secondary instrument is inserted through a central bore of the rod reduction instrument to introduce a cap and lock the cap to the seat securing the rod to the bone anchor.

    摘要： A dilator that facilitates implantation of an interspinous spacer is provided. The dilator includes a proximal portion and a tapered distal portion interconnected by an elongated body portion. The tapered distal portion is ideally suited for splitting ligamentous tissue for creating a posterior midline pathway through the supraspinous ligament as well as for distracting the adjacent spinous processes. Two oppositely located and longitudinally extending channels or grooves are formed in the outer surface of the dilator for stabilizing the dilator with respect to the spinous processes. An accompanying cannula together with the dilator form a system for the distraction of the adjacent spinous processes, stabilization of the spinous processes with respect to the system and creation of a working channel for the implantation of an interspinous spacer.

    摘要： An implantable spacer for placement between adjacent spinous processes in a spinal motion segment is provided. The spacer includes a body defining a longitudinal axis and passageway. A first arm and a second arm are connected to the body. Each arm has a pair of extensions and a saddle defining a U-shaped configuration for seating a spinous process therein. Each arm has a proximal caming surface and is capable of rotation with respect to the body. An actuator assembly is disposed inside the passageway and connected to the body. When advanced, a threaded shaft of the actuator assembly contacts the caming surfaces of arms to rotate them from an undeployed configuration to a deployed configuration. In the deployed configuration, the distracted adjacent spinous processes are seated in the U-shaped portion of the arms.
