Patient Data

Age: 35 years
Gender: Male

XR of the pelvis & Rt hip

There is no evidence of a recent cortical defect or fracture in the pelvis or right hip. 

A focal hyperostosis can be seen at the lateral aspect of the ischiopubic junction on the right.

Case Discussion

A focal hyperostosis can be seen at the lateral aspect of the ischiopubic branch on the right. This is the zone of insertion of the adductor muscles of the upper leg. Given the patients history of a 'muscle tear', the diagnosis of an old healed avulsion injury can be made.
