Fatigue fractures are secondary to excessive, unusual, repeated mechanicalstress, occurring on healthy bone. Bone scintigraphy (BS) with 99mTc-HMDP is anexcellent means of diagnosis. We report a case of stress fracture of thecalcaneus with scintigraphic diagnosis, in a marathon runner. Patient andMethods: He is a 40-year-old athlete in overtraining with right calcaneal painon running, intense at first, moderate in the middle and then persistent afterexercise. The interrogation found no trauma to the right foot and the x-ray ofthe foot was without abnormality. The so 3 phases were performed following an injectionof 564 MBq of 99mTc-HMDP, with a SPECT gamma camera. Results: Bone scintigraphyfound in the early phase, hyper-perfusion and hyper-fixation of the rightcalcaneal region compared to its left counterpart and in the bone phasepersistence of focal hyperfixation opposite the right calcaneus. Thisscintigraphic aspect of the right calcaneus in a overtrained marathon runner,in a painful context and in front of a normal X-ray, made us evoke a fractureof fatigue. A complementary CT scan performed two days after the BS was withoutabnormality. Conclusion: Fatigue fractures are micro-fractures generally notnoticed on radiography and CT. BS due to its high sensitivity is an excellentor the best tool for the early diagnosis of stress fractures.
