Influence of the glenoid track and glenoid bone loss on the apprehension test for shoulder instability.

Background: The investigation of Hill-Sachs and bony Bankart lesions continues to evolve. Patients with large bone lesions can present with a positive apprehension test even at ranges below 45° of abduction and external rotation of the shoulder. Modern concepts, such as glenoid track and quantification of glenoid bone loss, have been increasingly applied to shoulder instability.

Pseudotumor in Large Diameter Head Metal-on-metal Total Hip Replacement.

The authors describe a case of a large diameter head metal-on-metal total hip replacement that evolved with an inflammatory pseudotumor formation. The diagnosis was established by magnetic resonance imaging (MRI) with suppression of the metal artifact. The treatment consisted on the resection of the abnormal tissue and on the revision to a ceramic on cross-linked polyethylene hip replacement.
