title: Femoral stress abnormalities: improved scintigraphic detection with frog-leg view.
abstract: To identify a better scintigraphic imaging technique for detecting proximal femoral stress abnormalities, 51 consecutive patients with hip pain and the clinical suspicion of stress injury underwent three-phase bone scanning with technetium-99m methylene diphosphonate. Delayed scanning included anterior and frog-leg views of the hips. Fifteen patients had focal stress abnormalities of the femoral neck or lesser trochanter; all were detected with the frog-leg view, but only seven were detected with the standard anterior view. Stress abnormalities involving the lesser trochanter were depicted especially well on the frog-leg view.
