Abstract

As the osteoporotic patient population grows, various periprosthetic fractures that cannot be classified appropriately can occur around the femur after hip arthroplasty. We experienced two cases of periprosthetic insufficiency fractures at subtrochanteric area of the femurs around radiographically loose cemented femoral stems. The ages of the patients were 75 years and 83 years. Both patients could not recall any history of trauma before the onset of pain. Both were treated non-operatively. Both healed uneventfully and did not recur after two years of follow up. When the osteoporotic patient with cemented stem showed sudden hip or thigh pain without a history of trauma, great attention should be focused to find this lesion.

  Fig. 1 (A) Anteroposterior radiograph of right hip of patient 1 shows a thickened lateral cortex with a transverse uni-cortical fracture (arrow) at the subtrochanteric region. (B) The radiograph taken 8 months after the index symptom shows complete healing of previous fracture (arrow).

• 

  Fig. 2 (A) Anteroposterior radiograph of right hip of patient 2 shows marked thickening at lateral cortex with a transverse incomplete fracture (arrow) at the subtrochanteric region. (B) The radiograph taken 12 months after the index symptom shows complete healing of previous fracture (arrow).
