Effect of screw number on reconstruction plating.
Recently sacrificed bovine ribs and a hydraulic press were used to evaluate the effect that the number of screws has upon reconstruction plating. Reconstructed segments were subjected to five trials each for one, two, three, four, five, six, seven, and eight screws with increasing weights until failure. Increasing the number of screws increased the amount of weight resisted up to four screws per segment after which no additional benefits were realized (P < .001).
