A variable angle spinal fixation system is disclosed.

The first and second panels variably define an angle between these two panels.

This first component is phase-adjusted by a variable angle θ to a predetermined phase angle φ, and stored.

The system (30) includes two bone screws (32), a fixed angle screw (50) and a variable angle screw (60).

The bone fixation element (100) may be a variable angle locking screw.

The variable angle clamp 100 defines a bore 116 configured to receive the Schantz screw 45.

The adjustable flange (202) is configured to be positioned at a variable angle with respect to the body (28).

Disclosed herein is a variable angle elbow for connection of water supply hoses.

The angle between these polygons can be adjusted within a significant range (from 0 to 180 degrees).

In one exemplary embodiment, the spinal plating system includes a fixed angle bone screw and a variable angle bone screw.

The variable angel elbow of the present invention includes a first elbow part (11) having a linear, tubular shape.

Arrangements are also described for forming a variable angle coupling and also for forming a torque divider.

Variable angle locking bone screws can engage the bone plate at a selectable angle within a range of angles relative to the bone plate.

The size of the wedge can be adjusted over a variable angle as measured through an arc of the wedge.

One or more variable-angle reference beams are used to write simultaneously one or more holographic pixels.
