A simple technique for shoulder arthrography.

PURPOSE: To present a systematic approach to teaching a technique for arthrography of the shoulder. Using an adhesive marker-plate with radiopaque coordinates, precise sites for puncture can be identified and the need for fluoroscopic guidance obviated. MATERIAL AND METHODS: Forty-six glenohumeral arthrograms were performed in 45 patients; in 1 case involving examination of both shoulders. The stages of the technique are described in detail, as are the fundamental aspects of achieving an effective glenohumeral injection. Pain intensity was measured in all patients using a verbal description scale. RESULTS: Shoulder arthrography was successful in all cases. Average time taken for the procedure was 7 min, with no difference in the respective times required by an experienced radiologist and a resident. The procedure was well tolerated by most patients, with slight discomfort being observed in a very few cases. CONCLUSION: The arthrographic technique used in this study is simple, safe, rapid, and reproducible, and has the advantage of precise localization of the site for puncture without need for fluoroscopic guidance. The procedure described in this study can be of help in teaching residents and can reduce the learning curve for radiologists with no experience in arthrographic methods. It also reduces the time of exposure to fluoroscopy.

A new system for localization of nonpalpable breast lesions with adhesive marker plate.

The objective of this article is to present a new method of preoperative localization of nonpalpable breast lesions by means of an adhesive marker plate that makes an anteroposterior approach to the thoracic wall possible. Between January 2000 and September 2002, 41 consecutive mammographic localizations were performed with the adhesive marker plate. In most cases (n = 34) the lesions were microcalcifications. The mean age of the patients was 54.7 years. The device used consists of a square plate made of highly flexible plastic with an adhesive film on the back for firm attachment to the area of the breast surface corresponding to the approximate location of the lesion. This plate contains a network of holes and a system of radiopaque coordinates. The technique for its use is described step by step. All 41 lesions were localized: to within 5 mm or by transfixation of the lesion in 95.1% of cases (39/41) and to within 1 cm in the remaining 2 cases. Surgical excision of the breast lesions was carried out successfully in all cases, and in 56% (23/41) it was possible to use a periareolar incision. Histological findings revealed 24 benign and 17 malignant lesions. This new technique permits the localization of nonpalpable breast lesions accurately, simply, and with very little discomfort to the patient. The anteroposterior approach simplifies the surgeon's task in the management of these lesions.
