Abstract

A femoral neck stress fracture in child is rare, particularly in bilateral case. It is easy to miss initially or may be misdiagnosed. The authors experienced a case of bilateral femoral neck stress fracture in a 10-year-old boy with bilateral hip. The patient was successfully healed by conservative treatment. We report this rare case with a review of the literature. A femoral neck stress fracture should be included in the differential diagnosis in children who present with sustained hip or groin pain.

Figure

• 

  Fig. 1 Radiographs were obtained at 4 weeks from the start of pain. (A) Antero-posterior radiographs of the hip joint showed sclerotic line along the left femoral neck (arrowhead). (B) Close-up of right femoral neck showed inferomedial cortical interruption which was typically seen in compression type of fracture by Devas classification (arrow).

• 

  Fig. 2 (A) Stress fracture of the left femoral neck indicated low signal intensity in T1-weighted image. (B) T2-weighted image showed fracture line along the left femoral neck and interruption of cortex at inferomedial portion of the right femoral neck. (C) Sagittal T2-weighted image of the right femoral neck.

• 

  Fig. 3 (A) Radiograph, 6 weeks after the onset of pain, showed callus formation along the bilateral femoral neck. (B) After 10 weeks from the initial pain, radiograph demonstrate nearly complete bony union bilaterally.

• 

  Fig. 4 Radiographs obtained 4 months (A) and 12 months (B) after the initial pain developed.
