Case Discussion

The patient presented to the emergency department at the time of injury but the fracture was not demonstrated on the x-ray or the subsequent CT (even in retrospect a definite fracture line was not seen). An MRI was not performed. Repeat x-rays four weeks after the initial injury show the fracture clearly - the patient proceeded to ORIF.
