Diagnosis failure led to the recurrence of an intra-articular osteoid osteoma at the talus neck after arthroscopic excision.

Juxta-articular localization is not exceptional for an osteoid osteoma of the ankle. Arthroscopic treatment has been recently proposed. A case of recurrence of an osteoid osteoma at the talar neck is reported after arthroscopic resection performed following a diagnosis failure.

Evaluation of rotator cuff tendon tears: comparison of multidetector CT arthrography and 1.5-T MR arthrography.

Purpose: To compare the diagnostic performance of multidetector computed tomographic (CT) arthrography and 1.5-T magnetic resonance (MR) arthrography in the evaluation of rotator cuff lesions, with arthroscopic correlation.

Materials And Methods: This study was approved by the institutional ethical committee, and informed consent was obtained from all patients.
