Gilula's lines

Gilula carpal arcs.

Gilula's lines are three arcs drawn on an AP radiograph of the wrist used to assess the alignment of the carpal bones.^[1] They were first described by Louis A. Gilula in 1979.^[2]

Clinical use

There should be no step-off in the contour of the lines when drawn on a normal wrist.
