A nail assembly for use in trauma surgery is provided. The nail assembly includes an intramedullary shaft including a first transverse passage and a second transverse passage in the shaft. The, first transverse passage and the second transverse passage do not contact each other on the shaft. The nail assembly also includes a first shaft extending through the first transverse passage in the intramedullary shaft and a second shaft extending through the second transverse passage in the intramedullary shaft. The second shaft includes an engagement feature configured to bring the second shaft into contact with the first shaft. The engagement feature may be in the form of a lateral mechanical feature that provides simultaneous unilateral coupled motion of the first shaft with the second shaft through the transverse passages in the intramedullary shaft.
