Summary
This study describes fatigue fractures in young males, often misdiagnosed as bone sarcoma. Imaging findings help differentiate these tibial fractures from malignant tumors.
Area of Science:
- Orthopedics
- Radiology
- Sports Medicine
Background:
- Fatigue fractures of the proximal tibia can present with symptoms mimicking bone sarcoma.
- Accurate diagnosis is crucial for appropriate patient management and treatment.
Purpose of the Study:
- To describe the clinical and radiological features of fatigue fractures along the soleal line of the proximal tibia.
- To differentiate these fractures from malignant bone tumors.
Main Methods:
- Review of clinical and radiological findings in nine patients with proximal tibial fatigue fractures.
- Analysis of plain radiography, bone scan, and computed tomography (CT) findings.
- Comparison with features of bone sarcoma.
Main Results:
- Nine male patients, mostly under 18, presented with tibial fatigue fractures.
- Radiography showed periosteal reaction and cortical thickening.
- Bone scan revealed increased uptake, and CT demonstrated perifracture edema without a soft-tissue mass.
- Fractures were best visualized on CT cortical window settings.
Conclusions:
- Fatigue fractures of the proximal tibia have distinct radiological features.
- Distinguishing these fractures from sarcoma is possible through careful evaluation of imaging characteristics.
