This article describes the steps involved in production of a computer teaching module on the radiographic diagnosis of arthritis. The module was part of a research project aimed at producing seven computer teaching modules. Several staff radiologists and residents were involved, as well as a consultant on medical education. A generic shell program was used as a frame for all seven modules. The author of each module then filled in the empty pages of the shell with the appropriate text and images, along with additional short program scripts. The module on the radiographic diagnosis of arthritis described and illustrated the basic radiographic signs of arthritis. Practice cases were also included, and interactive and hypermedia features were implemented. The modules were then evaluated by means of task list tests and interviews. The experience was judged to have been successful, although the amount of time spent by some authors was much more than expected.

This article reviews the numerous applications of ultrasound in the musculoskeletal system. Emphasis is made on the important and often under-utilized role of ultrasound in infections, vascular lesions, arthritis, and trauma.

A double-blind, prospective study of 45 patients with adhesive capsulitis of the shoulder compared the therapeutic efficacy of distensive and nondistensive arthrography in combination with the intra-articular injection of corticosteroids. After 1 and 3 months there was no significant difference between the two treatments in the degree of pain or of limitation of movement experienced by the patients. More than 80% of the patients who experienced pain at rest and nocturnal pain improved under both treatment regimens. Scapulohumeral mobility increased significantly but only partially within the first month of treatment. Articular capacity and the duration of symptoms before treatment were of no prognostic value.
