The posterior part of the calcaneal tuberosity had displaced moderately, but healing of the fracture (arrows) was evident twelve weeks later.



There is no abnormal finding on this radiograph of the calcaneus made twenty-four weeks after total knee arthroplasty and five days after the onset of symptoms.



The sclerotic line (arrows) had become apparent two weeks later.



There is only a slight sclerotic line (arrows) in the calcaneus on this radiograph made seven weeks after total knee arthroplasty and one week after the onset of symptoms.



The sclerotic line (arrows) had become more apparent three weeks later.



There are no abnormal findings of the calcaneus on the radiograph made eleven weeks after total knee arthroplasty and five days after the onset of symptom.



A sclerotic line (arrows) had become apparent in the calcaneal tuberosity two weeks later.



A sclerotic line (arrows) traverses the long axis of the calcaneal tuberosity at seventeen weeks after total hip arthroplasty and five weeks after the onset of symptoms.



T1-weighted magnetic resonance imaging clearly demonstrates a linear zone of low signal intensity (arrows), which indicated a fracture line, and a broader, poorly defined area of signal

intensity alteration in the bone marrow.
