The purpose of this study is to define the anatomy of the metacarpophalangeal and interphalangeal joints of the thumb and fingers with images obtained using an 11.7T MR scanner. Commonly encountered pathologic lesions involving these joints will be depicted with clinical protocols at 1.5 and 3.0T, emphasizing diagnostic criteria.

The anatomy and structure of the thumb and fingers will be profiled using high resolution MR imaging at 11.7T in human cadaveric donors. Commonly encountered pathologic lesions will then be demonstrated and characterized, reviewing diagnostic criteria and pertinent grading systems. Lesions will include commonly encountered injuries such as collateral ligament injuries, pseudo-Stener lesions, sagittal band injuries, central slip extensor tendon tears, pulley lesions, and Boutonniere and pseudo-Boutonniere deformities.

Review of the complex anatomic structures of the thumb and fingers with high resolution imaging will further ameliorate the radiologist’s understanding of pathologic lesions and injury involving those joints.
