title: [Insufficiency fracture of the sacrum].
abstract: Three cases of insufficiency fracture of the sacrum are reported. Cortical disruption and linear sclerosis with or without linear fracture line at the upper sacral segment parallel to the sacroiliac joint are characteristic. Bone scintigram is suitable for screening, but plain radiographic and CT findings are diagnostic. Insufficiency fracture of the sacrum should not be confused with other conditions, such as metastatic disease.
