          Abstract

          Elbow derangements are common. Clinical examination is supplemented by magnetic resonance imaging (MRI) for optimal diagnostic assessment of such disorders. 3-dimensional (3D) imaging is feasible on newer MR scanners in acceptable acquisition times. Isotropic high-resolution 3D MRI affords multiplanar reconstructions and aids in diagnostic evaluation of elbow disorders and pre-/post-surgical assessments. The article details technical considerations of 3D elbow MRI and discusses its role in diagnostic evaluation of elbow disorders with relevant comparisons to 2D MRI and emphasizes as to how such advanced imaging assists in pre- and post-surgical assessments of tendon and ligament derangements.

          Tennis elbow. The surgical treatment of lateral epicondylitis.

          Of the 1,213 clinical cases of lateral tennis elbow seen during the time period from December 19, 1971, to October 31, 1977, eighty-eight elbows in eighty-two patients had operative treatment. The lesion that was consistently identified at surgery was immature fibroblastic and vascular infiltration of the origin of the extensor carpi radialis brevis. A specific surgical technique was employed, including exposure of the extensor carpi radialis brevis, excision of the identified lesion, and repair. The results at follow-up were rated as excellent in sixty-six elbows, good in nine, fair in eleven, and failed in two. There was an over-all improvement rate of 97.7 per cent, and 85.2 per cent of the patients returned to full activity including rigorous sports.

            Epicondylitis: pathogenesis, imaging, and treatment.

            Epicondylitis commonly affects the elbow medially or laterally, typically in the 4th or 5th decade of life and without predilection with regard to sex. Epicondylitis is an inflammatory process that may be more accurately described as tendinosis. In the lateral epicondylar region, this process affects the common extensor tendon; in the medial epicondylar region, the common flexor tendon is affected. The condition is widely believed to originate from repetitive overuse with resultant microtearing and progressive degeneration due to an immature reparative response. Advances in understanding of the anatomy and pathophysiology of epicondylitis have shaped current treatment practices. Conservative measures are undertaken initially, because symptoms in most patients improve with time and rest. Those who fail to respond to conservative therapy are considered for surgical treatment. When surgery is contemplated, magnetic resonance imaging or ultrasonography is useful for evaluating the extent of disease, detecting associated pathologic processes, excluding other primary sources of elbow pain, and planning the surgical approach. Familiarity with the normal anatomy, the pathophysiology of epicondylitis and its mimics, and diagnostic imaging techniques and findings allows more accurate diagnosis and helps establish an appropriate treatment plan.

              Nerve entrapment syndromes of the elbow, forearm, and wrist.

              Nerve entrapment syndromes usually have typical clinical presentations and findings on physical examination. Imaging can be used to evaluate a structural cause of the entrapment, such as a mass or enlarged muscle or to show secondary findings that confirm the diagnosis, such as nerve swelling or muscle edema or atrophy. This article will review entrapment syndromes of the elbow, forearm, and wrist.
