Abstract

A non-traumatic, incomplete insufficiency fracture commonly involves the lateral side of the femoral cortex; whereas a non-traumatic, incomplete stress fracture commonly involves the medial side of the femoral cortex. Here, we describe a case of a 66-year-old woman with a two-month history of bilateral thigh pain without trauma or medication usage who was diagnosed with bilateral subtrochanteric insufficiency fractures involving the medial side of the femoral cortex.

Figure

  • Fig. 1 (A) AP and (B) lateral plain radiographs of both femurs show no bony abnormalities.

  • Fig. 2 Bone scan shows increased uptake in the medial subtrochanteric areas of both femurs.

  • Fig. 3 T2-weighted signal intensity (A) coronal and (B, C) axial MR images of both femurs show increased signaling of the medial subtrochanteric area of the marrow. Linear low signal intensities are seen at just below the lesser trochanter in left femur and 2 cm below the lesser trochanter in right femur.

  • Fig. 4 After 3 months, (A) AP and (B) lateral plain radiographs of both femurs show no interval change.
