Abstract: This application describes surgical instruments and implants for building a posterior fixation construct across one or more segments of the spinal column during a medialized posterior lumbar interbody fusion (PLIF) procedure.

Abstract: A plaster collar assembly having a first ring, a second ring secured to the first ring, and a mechanism arranged at an outer periphery of at least one of the rings for axially displacing the first and second rings during rotation of the secured rings relative to each other.

Abstract: A recessed lighting fixture includes a frame having an aperture and at least one mount and a reflector including at least one torsion spring configured to be received in the mount when the reflector is mounted to the frame. A recessed lighting fixture also includes a frame and a reflector. The frame includes an aperture and a pair of mounts separated around a circumference of the aperture in a first direction that differs from a distance in a second direction (i.e., by an angle of other than 180°). The reflector includes a pair of torsion springs separated around a circumference of the reflector in the same way. The reflector is designed to be received in the mount when the reflector is mounted to the frame. The aperture may be a noncircular opening. A junction box that can be used with a recessed lighting fixture includes a retaining spring and a plate having at least one edge having a slot cut into the edge. The retaining spring is mounted on the plate and includes a retaining portion and an outer edge.

Abstract: A recessed light fixture for a ceiling includes a trim ring, a pivot ring mounted on the trim ring for rotation about a vertical axis, and an enclosure portion rotatable about a horizontal axis intersecting the vertical axis. The enclosure portion includes upper and lower enclosures. The upper enclosure carries a lamp socket in horizontal offset relationship to the vertical and horizontal axes. The lamp socket defines a longitudinal axis which coincides with a center axis of a downwardly open circular mouth of the lower enclosure. The lower enclosure intersects the upper enclosure to form therewith a circular waist. Each of the upper and lower enclosures have a cross-sectional area increasing in size in a respective direction away from the waist. A center axis of the waist intersects the center axis of the mouth at an oblique angle.
