A bone plating system is provided that permits maintenance of a compression force while also accommodating bony subsidence, among other features. Methods of implantation are also provided that improve alignment and placement during implantation and avoid maneuvers that weaken the vertebral bodies. A modular distraction screw is placed during the initial stages of surgery when all relevant landmarks are still intact. After completion of the surgical bone work, a proximal end of the distraction screw is detached, leaving a protruding distal segment implanted in the centerline of the vertebral bodies above and below the newly fused disc space. A bone plate is guided into proper position relative to the upper and lower vertebra by attaching the bone plate to the protruding distal segments.

A Low Capacity Sodium Hypochlorite Generation (LCHG) system uses batching rather than the conventional continuous flow method in the production of sodium hypochlorite. Batching eliminates the need for metering pumps for brine and dilution water, as well as their associated controls and maintenance/servicing demands. Batching also precisely controls the ratio of brine to dilution water in the electrolyzer to produce a consistent strength sodium hypochlorite solution. Consequently, the LCHG system has fewer components, greater reliability and simpler maintenance than the continuous-flow on-site electrolytic chlorination systems.
