Various techniques were evaluated to determine the best method for reducing small bowel involvement in pelvic irradiation. Fourteen patients receiving radiation in pelvic area were enrolled for this study. Five sets of small bowel images were obtained. Patients were positioned on a simulation couch with full bladder in prone and supine positions and 2 sets of images were taken. Then they were asked to empty their bladder and 2 sets of images were taken in prone and supine positions. A belly board device (BBD) was placed and one set of images was obtained. Using a software, the area of small bowel inside treatment field was contoured, measured, and analyzed. In both full and empty bladder cases, small bowel area reduction was observed in prone position as compared to supine position. Especially statistically significant reduction is noted in lateral film. An average decreases of 13% in PA and 26% in lateral direction were noted with bladder distention as compared to empty bladder. With the use of BBD for empty bladder, a significant reduction of 62.8+/-27.1% and 63.1+/-32.9% in PA and lateral directions were observed as compared to without BBD in prone position, respectively. In conclusion, the best sparing of small bowel concerning the area included in the treatment fields was achieved with BBD in prone position with empty bladder. However, further reduction is expected if the bladder was filled fully because the analysed data with empty vs full bladder study shows increased sparing of small bowel with distended bladder.

The purpose of this study is to evaluate the morphologic findings of the labrum and capsuloligamentous structures in the normal and unstable shoulders and to compare the effectiveness of double contrast arthrographic findings which were taken with supine and prone position. We reviewed the computerized tomographic arthrogram in 9 cases of normal shoulder and l3 cases of shoulder instability. We evaluated the shape of the labrum, the attachment of anterior capsule and the amount of capsular laxity. Capsular laxity was compared each others in normal, the unidirectional instability and the multidirectional instability. Among these materials, we simultaneously performed CT arthrogram with supine and prone position and evaluated which is more reliable and accurate. Scapular inclination was ahout 25 degrees in the supine position and ahout 60 degrees in the prone position. Normal glenoid labrum varied in size and shape, so its lack of a classic appearance might not indicate a labral tear. Variations existed in the anterior capsular attachment onto the glenoid. The anterior capsule was used to attach far away from the glenoid rim. but it might not indicate an anterior instability. With the prone position, the labral lesion took more excellent visualization due to the contrast coating on the glenoid labrum in both anterior and posterior. Anterior capsular expansion was seen well with prone position in anterior instability. In summary, for proper interpretation of the instability, awareness of the morphologic variations of the labrum and capsuloligamentous structure is important. CT double contrast arthrography with prone position has made a significant contribution to improving and easing the documentation of variety of anatomic abnormalities. Now we recommend the prone position in CT arthrogram for imaging glenoid labrum pathology in shoulder instability.

The posterolateral approaches to the spine is an effective method for the neural decompression and the spinal stabilization. This procedure has an advantages of an one-stage posterolateral decompression-stabilization. We have experienced 8 patients with burst fracture in the thoracolumbar junction. A three-quater prone position was used for patient positioning. No patient showed neurologic deterioration after surgery. Patient positioning and the operative approach are described and illustrated.

PURPOSE: Authors designed a customized Small Bowel Displacement System (SBDS) to displace the small bowel from the pelvic radiation fields and minimize treatment-related bowel morbidities. METHODS AND MATERIALS: From August 1995 to May 1996, 55 consecutive patients who received pelvic radiation therapy with the SBDS were included in this study. The SBDS consists of a customized styrofoam compression device which can displace the small bowel from the radiation fields and an individualized immobilization abdominal board for easy daily setup in prone position. After opacifying the small bowel with Barium , the patients were laid prone and posterior-anterior (PA) and lateral (LAT) simulation films were taken with and without the SBDS. The areas of the small bowel included in the radiation fields with and without the SBDS were compared. RESULTS: Using the SBDS, the mean small bowel area was reduced by 59% on PA and 51% on LAT films (P=0.0001). In six patients (6/55, 11%), it was possible that no small bowel was included within the treatment fields. The mean upward displacement of the most caudal small bowel was 4.8 cm using the SBDS. Only 15% (8/55) of patients treated with the SBDS manifested diarrhea requiring medication. CONCLUSION: The SBDS is a novel method that can be used to displace the small bowel away from the treatment portal effectively and reduce the radiation therapy morbidities. Compliance with setup is excellent when the SBDS is used.
