title: Ultrasonography is a nonspecific method in the evaluation of joints.
abstract: Two cases of unilateral abnormal ultrasonographic findings in the hip joints are introduced. The correct diagnoses were detected by radiography after the failure of intra-articular glucocorticoid injections given as first aid. Ultrasonography (US) has poor specificity, since all phenomena causing effusion into the joint cavity may be detected as abnormal by US, and may include stress fractures and malignant myeloma, as we show here. In the case of an abnormal ultrasonographic finding in a joint, the recent radiological status should also be considered.
