Abstract

Stress fractures occur when the loads applied to a bone exceed the mechanical resistance and fall into two groups. Fatigue fractures, in which abnormal mechanical stress is applied to a normal bone, and insufficiency fractures, in which fracture occurs when stress of normal activity is applied to a bone that has decreased elastic resistance. Femoral shaft insufficiency fractures are reported rarely in patients with postmenopausal osteoporosis. We report a case of repetitive insufficiency fractures of the femoral shaft in 70 year-old female with marked osteoporosis.

Keywords: Femoral shaft, Repetitive insufficiency fractures

Figures and Tables

Fig. 1

Femur anteroposterior (A) and lateral (B) radiographs shows 3 radiolucent lines of lateral femoral cortex with endosteal and periosteal new bone formation.

Fig. 2

Whole body radionuclide scan shows a focal uptake (dotted arrow) and two tiny transverse linear uptakes (linear arrows) of right femur shaft.

Fig. 3

CT scan of distal femoral shaft shows thickened lateral femoral cortex and endosteal new bone formation.
