Postoperative Shoulder Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) and MR arthrography have proven invaluable for managing the postoperative shoulder, particularly in relation to the rotator cuff and labrum. MRI has proven to be an…
The Rotator Interval and Long Head Biceps Tendon: Anatomy, Function, Pathology, and Magnetic Resonance Imaging
The rotator interval is an anatomically defined triangular area located between the coracoid process, the superior aspect of the subscapularis, and the anterior aspect of the supraspinatus. It is widely…
Superior Labrum Anterior and Posterior Lesions and Microinstability
The glenohumeral joint provides the greatest range of motion of any joint in the human body. Over the past several decades, histologic studies, biomechanical studies, and improved arthroscopic techniques have…
The Rotator Cable: Magnetic Resonance Evaluation and Clinical Correlation
The rotator cable is an extension of the coracohumeral ligament coursing along the undersurface of the supraspinatus and infraspinatus tendons. The rotator cable is thought to play a role in…
The Throwing Shoulder: the Orthopedist Perspective
The extreme range of motion at the shoulder, high velocities and stresses, and repetitive nature of the throwing motion place the throwing athlete at risk for a wide range of…
Internal Impingement Syndromes
Internal causes of impingement are secondary to rotator cuff and capsular dysfunction and are categorized by the location of the impingement and the underlying pathophysiological or mechanical cause of the…
Magnetic Resonance Imaging of Rotator Cuff Disease and External Impingement
Magnetic resonance (MR) imaging plays a major role in helping to identify rotator cuff disease and in demonstrating the pathology associated with external impingement. Many surgeons rely on MR imaging…
Novel Anatomic Concepts in Magnetic Resonance Imaging of the Rotator Cuff Tendons and the Footprint
The anatomic and histologic descriptions of the rotator cuff tendons and footprints are continuously evolving, and new discoveries have led to novel concepts in our understanding of rotator cuff tendon…
Technical Update on Magnetic Resonance Imaging of the Shoulder
Improvement in both hardware and software has opened up new opportunities in magnetic resonance (MR) imaging of the shoulder. MR imaging at 3-T has become a reality, with the prospect…
Patterns of Perineural Tumor Spread in Head and Neck Cancer
Perineural tumor spread (PNS) is a mode of neoplastic spread whereby tumor cells use neural conduits to escape the borders of a primary tumor. MRI is generally favored over CT…
