Gowers' sign in discitis in childhood.

Three cases of discitis in early childhood presented with acute refusal to walk or change in gait pattern without neurologic deficits. In all three, a Gowers' sign was observed, although none had muscular weakness. The diagnosis of discitis was confirmed by the characteristic radiographic findings on survey lumbosacral films and/or by a hot spot at the L3 level on technetium bone scan.
