The invention consists of disc replacement implant for the lumbar spine designed for insertion into the disc space via a posterior approach. The implant can be stabilized in the disc space by connection to the vertebra or can be connected to dynamic spinal stabilization device consisting of interconnected bullets nested in a spring nested in a woven sleeve. By controlling the limits of elongation and compression the device prevents movement beyond normal physiological limits. In the midrange of movement flexibility is allowed. A method for using the dynamic spinal stabilization device is also provided.

A system and method for ameliorating spinal column anomalies, such as scoliosis, while accommodating growth of juvenile patients, which include pedicle screws and an extendable telescopic spinal rod of non-circular cross section. Each pedicle screw includes spinal rod engagement means of complementary shape to the spinal rod for allowing longitudinal movement of the spinal rod, while resisting axial rotation of the pedicle screw relative to the spinal rod. The spinal rod is thereby allowed to slide longitudinally as attached vertebrae move during growth, while movement in other directions is arrested to preserve a proper orientation of involved vertebrae and to maintain scoliotic correction in three dimensions.

Devices and methods for creating lumens in the articular process of the vertebra are provided. An embodiment of the invention can be a tool that can cut a curved lumen through the articular process. The tool can have a lumen-forming arm with a rotating drill contained within that can be powered by a drill motor. The lumen-forming arm can be axially translated to cut a path through the articular process. Methods of using the resulting lumens to anchor or stabilize facet joint prosthesis, and also altering the spacing and motion at the facet joints of the vertebral column, are provided.

A driver tool for a spinal implant having an implant body and an anchoring screw portion, and a nut member screwed onto a head portion of the implant body and having an upper wall formed with a tool engagement groov. The driver tool includes an elongated shaft, and a tubular tool end having substantially the same diameter as that of the nut member. The tubular tool end has an engaging segment engageable with the engagement groove formed on the upper wall of the nut member.

A computer program for spine mobility simulation is configured, if running on a computer, to cause the computer to perform the following steps: a) accessing bio-metric data which relate to the spine of a patient, the spine having at least one compromised spine segment; b) displaying a model of the spine of the patient comprising a plurality of vertebrae; c) enabling a user to change the position of at least one of the vertebrae of the spine model; d) computing the effects of the position change on the remaining vertebrae; e) displaying the spine model in a new configuration, thereby taking into account the position changed by the user in step c) and the position changes of the remaining vertebrae computed in step d).

High loft, low density nonwoven webs are produced by forming substantially continuous, spunbond, crimped, bicomponent fibers of A/B side by side morphology in an unheated fiber draw unit. The fibers are then heated and cooled in the absence of impeding forces to achieve maximum crimp in the z-direction and produce a web of lofted material. The resultant material is particularly suitable for use as an insulator. Particulates may be added to the webs if desired.

A cell reselection method by a user equipment (UE) receiving an MBMS service in a serving cell of a mobile communication system. The UE receives control data of the serving cell, including configuration information necessary for accessing MBMS control channels (MCCHs) of neighbor cells and control information necessary for accessing an MBMS data transport channel (MTCH) of the serving cell, over an MCCH of the serving cell, and stores the received control data, while the MBMS service is provided in the serving cell. If cell reselection to a target cell, which is one of the neighbor cells is determined, the UE moves to the target cell by utilizing configuration information stored for the target cell.

A vehicle with protection against the effects of an exploding land mine is provided, in which a military wheeled vehicle is provided with wheel axels and drives built into front and/or rear building blocks. The vehicle is divided into multiple building blocks, although a three block construction is desirable (i.e., a front building block, a rear building block, and a main building block). A residual mobility of a remaining portion of the vehicle is preserved, even though one of the front building block or the rear building block is separated from the main building block due to the explosive shock wave generated by driving over and detonating a land mine, because each of the front building block and the rear building block has a drive for rotating the wheel axel connected to the block.

A system and method for ameliorating spinal column anomalies, such as scoliosis, while accommodating growth of juvenile patients, includes pedicle screws and a spinal rod of non-circular cross section. Each pedicle screw includes spinal rod engagement mean for achieving a slide-only engagement between each segment of said spinal rod that is respectively engaged with the pedicle screw. Pedicle screws are thereby allowed to slide longitudinally along the spinal rod as attached vertebrae move during growth, while movement in other directions is arrested in order to preserve a proper orientation of involved vertebrae to maintain scoliotic correction in three dimensions.

The present invention provides wood adhesive binder compositions comprising a naturally occurring protein component, e.g. soy flour, and an oxazoline-functional group containing polymer or resin component, the two components in a solids weight ratio of from 60:40 to 98:2. As formulated, the compositions may comprise from 40 to 98 wt. % of the naturally occurring protein component, preferably, 50 wt. % or more. Preferably, the wood adhesive binder further comprises lignins or lignosulfonate. Where the wood adhesive binder compositions comprise lignins or lignosulfonates, they remain more fluid and workable at a higher pH such as, for example, 4.5 or more. Any of the compositions may be formulated with one or more in situ acid generator compound to insure more rapid cure on heating or pressing. The binder enables the provision of mechanically sound, low cost and biodegradable composites, such as, medium density fiberboard (MDF).

The present ergonomic computer chair relates to chairs for special purposes, and more particularly, to computer operator's chair which is ergonomically designed to prevention of orthopedic and cardiovascular diseases and creation of psychophysical comfort, especially as regards reduction of fatigability during long-lasting work with computer. The ergonomic computer chair includes a seat with a backrest and a pedestal with a support frame made in the circular arc form, a support ring installed on the support frame wherein said support ring can rotate around its axis. The backrest is made of a rigid part and an elastic part separated from one other by at least three elastic bladders connected to a compressor by air tubes having electric valves. The rigid part of the backrest is hinged to the seat, and the seat is hinged to a seat inclination drive and to a footrest. A mounting of the computer monitor and keyboard is made by means of a movable sector which is made as a arched pipe with centering bearings. The chair has electric drives to move the support ring along the support frame of the pedestal, to move the movable sector along the support ring, to move the monitor longitudinally and to control monitor's inclination. This makes it possible to change the user's body position within the space against the Earth's gravitational field vector during the entire time of the work with computer. The use of the proposed device reduces the probability of orthopedic diseases occurrence, creates comfort and increases efficiency of the computer user.
