Abstract: Compression-distraction spinal fixation systems, and methods of performing compression-distraction spinal fixation, are provided that include screw-rod constructs having a ratcheting mechanism. Bone screws of the screw-rod constructs can have a pawl that engages ratchet teeth on the rod of the screw-rod construct. The bone screw can be ratcheted along the length of the rod to apply distractive or compressive forces.

Abstract: Medical devices and kits for dynamically stabilizing or preserving motion in a spine and limiting adjacent, non-adjacent, or isolated segment degeneration of the spine while providing a controlled, determinable range of motion at the treated site, as well as methods for surgical use of the system.

Abstract: A monolithic material including a first region having a first variability of strength and a second region joined to the first region, the second region having a second variability of strength, wherein the monolithic material has a variability of strength less than the first variability of strength of the first region and less than the second variability of strength of the second region.

Abstract: A monolithic orthopedic implant including a porous region having a form of interconnected porosity similar to cancellous bone to promote skeletal fixation by bone ingrowth, a transition region adjacent to and integrally joined to the porous region, the transition region having a form of interconnected porosity similar to subchondral bone, a substantially dense region integrally joined to the transition region and having a perimeter, and a surface on the substantially dense region, the surface having a finish adapted for articulation against native articular cartilage.

Abstract: A device for correction of a spinal deformity. In one embodiment, the device includes a cable having a first end portion, and an opposite, second end portion attachable to a vertebra, and means for adjusting the tension of the cable so as to impose a corrective displacement on the vertebra.

Abstract: An intervertebral disc prosthesis for placement between a first vertebra and a second vertebra adjacent to the first vertebra. In one embodiment, the intervertebral disc prosthesis includes a resilient member, a first support member and a second support member. The first support member and the second support member are housed into the resilient member that is arranged, in use, to be secured to the first vertebra and the second vertebra, respectively. The intervertebral disc prosthesis can generate a coupled motion in more than one possible direction responsive to a possible movement of at least one of the first vertebra and the second vertebra, among the resilient member, the first support member and the second support member.

Abstract: An intervertebral disc prosthesis that comprises a deformable flexure with an axial cavity, the axial cavity extending along the axis of the flexure, and a slit defined in the perimeter surface of the flexure to provide flexibility to the disc member, the slit having a slit thickness. The slit may be in the form of a coil to impart a spring-like appearance and function. The intervertebral disc prosthesis further comprises a lower disc support housed in the axial cavity and an upper disc support housed in the axial cavity; with the lower and upper disc supports communicating with one another to provide support to the disc. The lower or upper disc support may alternatively be incorporated into the flexure.

Abstract: A method is provided for treating diamond-like carbon (DLC) with a hot liquid and/or ion beam. This treatment can reduce the contact angle of the coating. In certain example embodiments, at least oxygen gas is used in an ion beam source(s) that generates the ion beam(s) used for the ion beam treatment.

Abstract: A substrate is coated with a layer(s) or coating(s) that includes, for example, amorphous carbon in a form of diamond-like carbon (DLC). The DLC is then ion beam treated and/or treated with a hot liquid and/or vapor (such as hot water) so as to cause the contact angle &thgr; thereof to decrease. In certain example embodiments, at least oxygen gas is used in an ion beam source(s) that generates the ion beam(s) used for the ion beam treatment.

Abstract: An implantable intervertebral disc prosthesis that comprises a disc member having an upper surface, a lower surface, and a perimeter surface. The disc includes an axis at least one slit defined in the perimeter surface; the slit being of sufficient depth and thickness to provide flexure. The slit terminates in a perimeter opening larger than the slit thickness. The perimeter opening (i.e., hole) acts as a pivot point and relieves stress. The disc prosthesis optionally comprises a cavity with an upper seat defined on the lower surface, a lower disc having an upper and lower surface and a lower seat defined on the upper surface, and a support ball. The support ball engages the seat on the upper disc and the seat on the lower disc.

Abstract: A clamp with helical coils or springs defining a cavity to receive and secure rod members. The clamp also comprises a connection and tightening device for constricting the first and second helical coils around the respective rod members. These clamps have multiple uses including use as a device for securing a bone. In such a case, this embodiment may comprise a first and second stabilization bar, a pin, a pin attachment device, and a clamp. In another embodiment of the present invention, a clamp comprises connectors with cavities to house the helical springs. The connection and tightening device secures and tightens the first and second connectors by causing the helical springs to constrict about the rod member.
