A spinal implant includes an intermediate portion and a first portion extending in a transverse orientation from the intermediate portion. The first portion includes an inner surface connectable with vertebral tissue adjacent a lamina. A second portion is spaced from the first portion and extends in a transverse orientation from the intermediate portion. The second portion includes an inner surface connectable with vertebral tissue adjacent a lamina. At least one of the first portion and the second portion includes an outer surface having a mating element engageable with a mating element of a surgical instrument. Systems, surgical instruments and methods are disclosed.

Spinal implant system and methods of use

A spinal correction system comprises a first member configured for attachment to a first portion of vertebral tissue and a second member is configured for attachment to a second portion of the vertebral tissue spaced from the first portion. A third member has a non-flexible configuration relative to the first and second members and is configured for attachment to an apical portion of the vertebral tissue and along at least a portion of at least two vertebrae. The third member extends between a first end connected to the first member at a first transition configured for attachment to the first vertebral tissue and a second end connected to the second member at a second transition configured for attachment to the vertebral tissue. Methods of use are disclosed.

Spinal correction system and method

A medical implant device has in one embodiment a receiver member for receiving an elongated member, a crown member, an anchor member and a retaining member. An embodiment of the receiver member has an axial opening, a transverse channel, a chamber including at least one substantially flat wall, and a groove. An embodiment of the crown member has at least one substantially flat side. An embodiment of the anchor member has a head with at least one substantially flat surface that may be parallel to the anchor member's longitudinal axis, and an anchoring portion. An embodiment of the retaining member is a substantially flat clip. The crown member and anchor member are inserted into the chamber, and the retaining member is inserted into the groove beneath them. The anchor member may be pivoted substantially in one plane with respect to the receiver member until locked.

Adjustable bone anchor assembly

A fusionless correction system comprises a longitudinal element extending between a first end and second end. At least one fixation element is disposed with the longitudinal element and is configured for disposal in bone. A lock is disposed with the at least one fixation element and includes at least one bone penetrating projection. The lock is movable relative to the at least one fixation element between a first non-engaging configuration and a second engaging configuration such that the at least one bone penetrating projection extends beyond an outer surface of the at least one fixation element. Methods of use are disclosed.

This invention relates to interconnection assemblies for use with spinal fixation systems to treat spinal defects. The interconnection assemblies can include various spinal rod connecting members and interconnecting elements to secure the spinal rod connecting members to each other in variable orientations and lengths. The interconnection assemblies can be adjusted to minimize interference with the spinal column, bony processes, and associated neural, muscular, and ligament components of the spine all the while exhibiting a low profile. The interconnecting elements and related components can be provided as a completely assembled unit that does not inadvertently become disassembled prior to or during implantation.

Multi axial cross link connector system for spinal implants

Multi-axial, cross-link connector system for spinal implants

A bottom-loading multi-axial bone anchor apparatus is disclosed. The apparatus includes a receiver member, a crown member, a bone anchor and a retaining member. The receiver member defines an upper opening and a lower opening, which may form part of the same opening, a channel, and a groove. The crown member and bone anchor are loaded into the lower opening of the receiver member, and the retaining member fits around the bone anchor and into the groove in the receiver member. The bone anchor is capable of multi-axial positioning with respect to the receiver member. An elongated member is placed in the channel of the receiver member, contacting the crown member, and a compression member is applied via the upper opening. The compression member presses down on the elongated member, which presses down on the crown member and locks the bone anchor between the crown member and the retaining member.

Multi-axial bone screw assembly

A system for stabilization of the spinal column, including an elongate support member extending along an axis and a plurality of anchor members configured for anchoring to respective vertebrae. A first of the anchor members is engaged to the support member in a manner that substantially prevents axial movement of the support member relative to the first anchor member, and a second of the anchor members is engaged to the support member in a manner that allows substantially unconstrained axial movement of the support member relative to the second anchor member. In a further embodiment, a third of the anchor members is engaged to the support member in a manner that also allows substantially unconstrained axial movement of the support member relative to the third anchor member, with the second and third anchor members positioned on opposite sides of the first anchor member.

Systems, devices and methods for stabilization of the spinal column

An apparatus for use in orthopedic distraction or compression is disclosed. In the illustrated embodiments, two arms are provided that are connected by a rod or bar with a mechanism that enables the arms to be brought toward or away from each other. At the end of each arm, a tip for connecting to a bone implant is provided. The tips are pivotable with respect to the arms, and have an opening with a tab that allows insertion of an implant head having branches defining a channel. Once the tips are appropriately positioned, connected and locked to the bone implants, the mechanism can be operated to move the arms together in compression or apart in distraction.

Orthopedic instrument

A multi-axial bone fixation implant includes an elongated member, one or more bone anchor assemblies, and stabilizer members fitted within the elongated member. A bolt having a bone-threaded end and a machine-threaded end and an enlarged medial portion is also provided. The bolt is anchored into a bone, and its machine-threaded end passes through the elongated member and the stabilizer, and is engaged by a coupled washer and nut. The washer includes an oblong aperture, and the nut includes a projecting sleeve. The sleeve is inserted into the washer and expanded, and the washer retains the sleeve without impairing relative rotatability or translatability of the nut and washer. When locked by the nut and washer, the enlarged portion of the bolt is forced against the stabilizer, which locks against the elongated member. The elongated member can be fixed with respect to the anchor at an infinite number of multi-axial angles.
