Review Question - QID 8514

Figures 55a and 55b are the radiographs of a 5-year-old boy 6 weeks after he was treated for a minimally displaced tibia fracture in a long-leg cast that was recently removed by his pediatrician. He has been afebrile and laboratory evaluation reveals a white blood cell count of 8.3 x10⁹/L (reference range, 4.5-11.0 x10⁹/L), C-reactive protein of < 0.5 (reference range, 0.08-3.1 mg/L), and erythrocyte sedimentation rate of 2 mm/h (reference range, 0-20 mm/h). In addition to axillary freckling, what physical examination finding is most likely to be present in this patient?
