In addition, electrical stimulation may improve the fusion rate in patients undergoing both instrumented and non-instrumented surgeries. However, scientific data are inadequate to determine the magnitude of benefit associated with electrical stimulation in patients considered at average risk for fusion failure.
Most innovative: Legendary U.S. Marine sniper Carlos Hathcock made a 2,000-yard shot in 1967 during the Vietnam War with a .50-caliber Browning machine gun fitted with a scope mount of Mr Hathcock's own design. It was a record that stood for 35 years.
