An intervertebral implant may include an anterior plate forming a first monolithic structure defining a first end of the implant, and including at least two screw holes each configured to receive a bone screw; and a plurality of coils extending from the anterior plate about a periphery of the implant. The screw holes may be angled such that, when the implant is inserted between two adjacent vertebrae, bone screws are guided into the adjacent vertebrae.

Coiled implants and systems and methods of use thereof

An implant includes an anterior plate defining a first end of the implant and a posterior plate defining a second end of the implant opposite the first end of the implant. The implant also includes a central support portion extending between the anterior plate and the posterior plate. The implant further includes a side wall extending between the anterior plate and the posterior plate and defining a portion of the outside perimeter of the implant; a first exterior arced member disposed proximate the side wall and the posterior plate; and a first interior arced member is disposed proximate the central support member and the posterior plate. The exterior arced member and the interior arced member curve in a superior direction such that portions of the exterior and interior arced members form portions of a bone contacting superior surface of the implant.

A bone anchor () for attaching a rod () to a bone has an anchor member () for attachment to the bone and an anchor head () having a U-shaped opening for receiving the rod. The bone anchor also includes a locking cap () that has a main body () and a set screw (). Advantageously, in one embodiment the locking cap preferably is designed such that a single tool can be used to lock the locking cap in place on the anchor body preferably with a 90&#xb0; turn and preferably then drive the set screw to clamp the rod. The locking cap also preferably non-threadingly engages the anchor body. The anchor body preferably has an inclined surface on its top surface which elastically deflects extending tabs on the main body to secure the locking cap to the anchor body. A method of implantation and assembly of the bone anchor are also described.

Bone anchor with locking cap and method of spinal fixation

Implants, systems and methods of making and using thereof are described herein. The implants are formed from one or more coils, preferably a plurality of coils. Optionally the coils are included in a set or group of more than one coil. Optionally, the implant is symmetric about one or more planes. Typically an implant includes at least two coils (or sets or groups of coils) that are adjacent to each other intersect with each other at one or more intersection regions. Two or more coils may intersect at a plurality of intersection regions, optionally along an array of intersection regions, within the implant or on the outer side wall of the implant. Optionally, the implants include one or more plates to aid in fixation and/or insertion. The implants may be used in a variety of different spaces in the body that require bone growth.

An adjustable rod for spinal corrective surgery is provided that includes a first elongate member and a second elongate member, each having rod portions couplable to one or more bone connecting elements and expansion portions slidably moveable with respect to one another. A plurality of holes in each expansion portion are alignable with one another to choose the length of the adjustable rod and a locking element is inserted through a pair of aligned holes to couple the first and second elongate members and secure or fix the length of the expandable rod.

Adjustable rod assembly

A threaded bone anchor includes a plurality of recesses formed lengthwise along an exterior cylindrical surface for engagement with a driver instrument through which a user applies clockwise or counterclockwise torque for the insertion or removal of the bone anchor into and from bone. The bone anchor includes a cross-sectional geometry that minimizes the anchor's outer diameter, survives high insertion/removal torque without compromising the anchor's bending/shear strength, and allows a mating clamp to be attached to the entire non-threaded surface, including the recessed portion.

Spline drive for threaded post-type bone anchors

The present invention relates to a clamp, and, more particularly, to a clamp for securing the position of a bone anchor with respect to a longitudinal rod, preferably for use in the spine. The clamp may include a housing, a rod clamping assembly, and a bone anchor clamping assembly. The clamp preferably enables the longitudinal axis of the rod to be offset or laterally displaced from the longitudinal axis of the bone anchor. The rod clamping assembly and the bone anchor clamping assembly are preferably moveably coupled to the housing in order to provide increased flexibility to better accommodate the location and geometry of the longitudinal rod and to better accommodate bone positioning.

Clamps used for interconnecting a bone anchor to a rod

A surgical instrument for moving a clamp relative to a bone anchor to properly position and secure the clamp to the bone anchor. The surgical instrument including a housing, a socket assembly, a manipulating assembly, a gripping assembly and a reduction assembly.
