Abstract
A surgical instrument for correcting spinal deformities includes a tubular body adapted to receive a second instrument through the tubular body. The tubular body forms a transverse passage adapted to receive a longitudinal fixation element through the tubular body. The tubular body further includes first and second arms for connecting the surgical instrument to a vertebral anchor. The first and second arms include one or more anti-splaying features adapted to mate with anti-splaying features on the second instrument to prevent the first and second arms from splaying as the second instrument is inserted into the tubular body.
