Twenty-three patients with Salter 1 or 2 fractures of the distal tibia had follow-up with footprints to assess rotational deformities. Fourteen had external rotation deformity >+2 SD of the normal mean of 5° to 6°. Eight of the 14 had the finding of physeal widening of 2 mm or more. The widening was most commonly wedge-shaped and based anteriorly. The mean foot progression angle of the fractured sides was externally rotated 14°, and the mean foot progression angle of the uninjured sides was externally rotated 10°; both exceeded the normal mean. The fractured side mean was significantly more externally rotated than the uninjured side mean. Preexisting external rotation deformity may be a risk factor for these fractures. Closed reduction with long leg bent-knee casting is justified in more than half of these patients.
