A device for reconstructing a spinous process, the device comprising a main portion having at least a first engaging hole; one fixing bar transversely insertable into the engaging hole; and said main portion having at least one through-seat for inserting ligaments to be reconstructed. Other aspects are disclosed and claimed.

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.

Systems for distracting a facet joint and positioning a permanent implant in the joint are disclosed. The implants serve to retain a distracted position of the facet joint which is achieved with positioning of the leading end of a distraction tool in the facet joint and then distracting or enlarging the joint a desired amount. The permanent implant could be part of the distraction mechanism which can be separated from the delivery tool once the joint has been distracted or an auxiliary implant may be positioned before the distraction mechanism is removed from the distracted joint. The permanent implants can be solid, mechanical devices that may have fixation means thereon to hold them in place or injected fluids such as hydrogels or fluids confined within balloons.

An implantable device includes a barrel. The barrel has a first portion and a second portion. The implantable device includes a first plate having multiple projections extending from one side of the first plate, where the first plate is configured to movably couple to the first portion of the barrel. The implantable device includes a second plate having multiple projections extending from one side of the second plate, where the second plate is configured to movably couple to the second portion of the barrel. The barrel is configured to transition from a collapsed form having a first height to an expanded form having a second height, where the second height is greater than the first height.

An implant that can hold bone graft material, and receive support from adjacent tissues and structures. In one aspect, the implant has an attachment region to directly engage with adjacent tissues and structures. In another aspect, the implant is malleable and can be manipulated to conform to the adjacent tissues and structures.

Systems for the minimally invasive repair, stabilization and/or fixation of a fractured bone, such as a rib, are disclosed. The systems include one or more rods/support members that are designed to extend along a dimension of a bone being repaired and secure the fractured bone. The support members can be photodynamic and are formed using an expandable member that is filled with a light-sensitive liquid that is cured to form the rigid support member. Two or more clamps are used to secure the support member(s) to the rib or other bone. Minimally invasive surgical methods for securing the systems to a fractured bone are also disclosed.

An interspinous fusion device is described. The interspinous fusion device includes a spacer member and an anchor member. The spacer member has a ring with two or more anchor assemblies projecting laterally from substantially opposite sides of the spacer member ring. The spacer member further has a first zip lock flange and a second zip lock flange, each of the first and second zip lock flanges extends transversely from the spacer member ring wherein each of the first and second zip lock flanges each comprises a series of teeth protruding from it. The anchor member has a ring with two or more anchor assemblies projecting laterally from substantially opposite sides of the anchor member ring. The anchor member further has a barrel extending transversely from the anchor member ring. The barrel comprises a first column of recesses adapted to mate with the teeth of the first zip lock flange and a second column of recesses adapted to mate with the teeth of the second zip lock flange. The spacer member is adapted to slide over the barrel of the anchor member such that the series of teeth of the first zip lock flange mates with the recesses in the first column of recesses of the barrel, and the series of teeth of the second zip lock flange mates with the recesses in the second column of recesses of the barrel to secure the spacer member to the anchor member.

A surgical instrument system comprises surgical instruments for use with an implantable interspinous device having at least one pair of wings for securing the implantable device to a spinous process. The instrument system may include a surgical instrument for expanding or spreading the pair of wings to accommodate the spinous process. Further, a surgical instrument may be provided for crimping or compressing the pair of wings against the spinous process for secure attachment of the device to a vertebra. The surgical instruments may be configured similar to pliers and apply force to the pair of wings within a predetermined range so as to avoid damage, weakening or breakage of the pair of wings. The surgical instrument system may also include interspinous devices of differing sizes.

A spinal jack adapted for installation between first and second vertebral processes, including first and second inter-expandable jack halves arranged between retracted and expanded positions. Each of the jack halves further includes gripping portions adapted for engaging the vertebral processes. A geared mechanism provides for expanding or retracting the jack halves in order to establish a corrected adjusted orientation between the processes.

A spinal jack adapted for installation between first and second vertebral processes, including first and second inter-expandable jack halves arranged between retracted and expanded positions. Each of the jack halves further includes gripping portions adapted for engaging the vertebral processes. A worm gear mechanism provides for expanding or retracting the jack halves in order to establish a corrected adjusted orientation between the processes and includes each of stationary rotatable slave gears along with support stems with integrated worm gear interfaces for expanding the jack halves relative to each other.
