Continuity mistake: When Ethan Hawke and Uma Thurman are escaping form the party, the sleeve of Ethan's suit is ripped under the armpits when he hits the cop but in a few seconds you see his sleeve completely fixed. (01:11:40)
Continuity mistake: Irene's hair changes in the first scene. When arriving at Gattaca, it's a side part low hairstyle. When she's at her workstation, it's pulled straight back into a high bun. A few minutes later, when she's speaking with Vincent as they watch a rocket launch through the skylight, it's back to the initial style, a low French twist. (00:04:39 - 00:05:30)
Continuity mistake: Irene's hair changes in her final scene. She's wearing a tighter doughnut-shaped bun at Gattaca, when she's picked up by Anton to visit Jerome's home. When they reach the house, her hair is done quite differently, in a much larger and looser bun. (01:18:11 - 01:25:19)
Answer: The leg bones are fractured completely across, at a location between the rings of the device. Thereafter, while the bones are knitting back together, the device is periodically adjusted to drag the bones away from each other a fraction of an inch. The bones continue to grow toward each other to close the gap, gradually lengthening. It is an astoundingly painful way to add height.
