Purpose of the study was to analyze the supraspinatus outlet image of sagittal MRI in rotator cuff disease. We analyzed the sagittal views of the shoulder MRI of 78 cases without cuff tear. The cases were divided into 51 cases of rotator cuff disease group and 27 cases of control group. Six parameters of acromial tilt, coracoacromial ligament angle, length and height of coracoacromial triangle, length of acromial side of the baseline and distance of intrusion of the humeral head were compared for each group. The distance of intrusion of the humeral head was the most significantly different one, 0.52cm for rotator cuff disease group and 0.15cm for control group. Intrusion of the humeral head to the supraspinatus outlet space from the bottom may be a contributing factor developing rotator cuff disease. The intrusion may precede to tearing of the rotator cuff.

To evaluation of patients who have shoulder impingement syndrome is by diagnostic radiography. Shoulder impingement is a problem which occurs in young, active individuals as well as older individuals. In fact, the pain is probably caused by repetitive stress placed on the shoulder joint either through recreational activities of your occupation. Impingement series approach to radiographic examination of the shoulder is take five projections. First anteroposterior oblique projection. Second standard anteroposterior projection. Third superoinferior axial projection. Fourth supraspinatus outlet projection offers a view of the outlet of the supraspinatus tendon unit as it passes under the coraacromial arch. Fifth anteroposterior $30^{\circ}$ caudal projection will adequately demonstrate the anterior acromial spur or ossification in the coraacromial ligament and more reliable to demonstrate spurring of the anterior acromion than supraspinatus outlet projection. This decreased the need for additional radiographic veiws, reduces the patient's exposure to x - ray radiation and decreases use of film. This can lower the cost of the evaluation and improve patient satisfaction.

Background: The presence of an acromial spur implies a rotator cuff disorder due to impingement between the acromial spur and the rotator cuff. The purpose of the study was to observe acromial spurs using ultrasonography and to compare measurements between plain radiographs and sonograms. Methods: We retrospectively enrolled 51 consecutive patients with acromial spurs, which were interpreted on preoperative plain radiographs (supraspinatus outlet view and 30° caudal tilt) and preoperative sonograms. The ultrasonography transducer was held vertically and continuously moved laterally, which corresponded to the long axis of the long head of the biceps. The distance from the most distal margin of the original acromion to the most projected point of the acromial spur was measured. Results: No significant difference was found between the plain radiograph and ultrasonography measurements (p=0.186). A moderate to strong correlation was detected between the ultrasonography and supraspinatus outlet-view measurements (r=0.776, p=0.000). Conclusions: Anteriorly projected acromial spurs were well-visualized by ultrasonography. No discrepancy in acromial spur length was detected between the use of plain radiography (supraspinatus outlet view and 30° caudal-tilt view) and ultrasonography. The correlation coefficients between the plain radiography and ultrasonography measurements exceeded 0.7.

Purpose: To evaluate a usefulness of the simple radiograph in the patients with chronic shoulder pain 50 years and older. Material and method: 1152 patients with chronic shoulder pain and 100 asymptomatic individuals were involved in this study. All patients were 50 years and older. We excluded patients who had a history of fracture or dislocation. Radiographic interpretation was performed on a shoulder AP view, an axillary view and a supraspinatus outlet view. For statistical analysis, a chi-square test was performed. A p value of <0.05 was considered statistically significant. Results: Abnormal radiologic findings were identified in 369(32%) out of 1152 patients with a shoulder pain: greater tuberosity sclerosis, acromial sclerosis, subacromial osteophytes are common abnormal radiologic findings. A rotator cuff tear or impingement syndrome was identified on a final diagnosis in 61(85.2%) out of the 76 patients with radiologic abnormalities in both greater tuberosity and acromion (p<0.05). Abnormal radiologic findings were identified in 18% of the asymptomatic individuals. Conclusion: Simple radiographic analysis is an important primary diagnostic tool in patients (50 years and old) with chronic shoulder pain.

목적: 단순 방사선 사진상에서 견봉 및 상완골 대결절의 퇴행성 변화의 정도와 회전근 개 파열의 크기 사이의 연관성을 알아보고자 하였다. 대상 및 방법: 견관절의 자기 공명 영상을 시행한 퇴행성 회전근 개 파열 실험군 234예와 회전근 개 파열이 없는 대조군 284예 등 총 518예를 대상으로 하였다. 견관절 방사선 단순 촬영에서 퇴행성 변화의 정도를 관절와-상완 관절의 퇴행성 변화를 제외한 견봉과 대결절에서 골극의 길이와 형태의 변형에 따라 분류하였고, 자기 공명 영상에서 회전근 개의 파열의 정도 및 전층 파열의 크기를 분류하였다. 회전근 개의 파열의 정도와 크기에 따른 견봉 및 상완골 대결절의 퇴행성 변화 정도와의 연관성에 대해 알아 보았다. 결과: 견관절 단순 방사선 사진에서 보이는 견봉 및 상완골 대결절의 퇴행성 변화에 따른 MRI상 회전근 개 파열의 정도는 유의한 차이를 보였고(p<0.001), 견봉 및 상완골 대결절의 단순 방사선상 퇴행성 변화가 증가할수록 회전근 개 파열의 크기가 커지는 경향이 있었으며(p<0.001), 부분층 파열 보다 전층 파열 가능성이 높은 것으로 나타났다(p<0.001). 또한 고령 및 여자에서 회전근 개의 파열이 더 심하다는 결과를 얻었다(p<0.001, p<0.001). 결론: 퇴행성 회전근 개 파열 환자에서 견관절의 단순 방사선 사진상 견봉 및 상완골 대결절의 퇴행성 변화가 심할수록 회전근 개 파열의 크기가 더 크고, 나이와 성별도 관련 인자 중 하나로 사료된다.
