Ultrasonography of anterosuperior calcaneal process fracture: report of 2 cases.
OBJECTIVE
The purpose of this series is to describe the ultrasonographic findings of anterosuperior calcaneal process (ASCP) fracture.


METHODS
Two patients with ASCP fractures were examined with ultrasonography. Both of them had pain over the lateral aspect of the ankle 10 to 13 months after an injury. Initial radiographs had shown no evidence of bone fracture or bone avulsion.


RESULTS
In both cases, ultrasonography revealed the presence of a bone fragment adjacent to the ASCP suggestive of a misdiagnosed fracture. The latter was confirmed by radiographs. In 1 case, a hypoechoic thickening of the calcaneocuboid component of the bifurcate ligament was also identified on ultrasonographic scans.


CONCLUSIONS
Ultrasonography is potentially valuable in detecting clinically or radiographically occult ASCP fractures.
