Background: This study was designed to evaluate characters of the rotator cuff tear (RCT) recognized after primary shoulder dislocation in patients older than 40. Methods: From 2008 to 2019, patients who visited two hospitals after dislocation were retrospectively reviewed. Inclusion criteria were patients over 40 who had dislocation, with magnetic resonance imaging (MRI) undergone. Exclusion criteria were patients who lost to follow-up, combined with any proximal humerus fracture, brachial plexus injury, and previous operation or dislocation history in the ipsilateral shoulder. Also patients who had only bankart or bony bakart lesion in MRI were excluded. We evaluated RCTs that were recognized by MRI after the primary shoulder dislocation with regard to tear size, degree, involved tendons, fatty degeneration, the age when the first dislocation occurred, and the duration until the MRI was evaluated after the dislocation. Results: Fifty-five RCTs were included. According to age groups, the tear size was increased in coronal and sagittal direction, the number of involved tendons was increased, and the degree of fatty degeneration was advanced in infraspinatus muscle. Thirty-two cases (58.2%) conducted MRI after 3 weeks from the first shoulder dislocation event. This group showed that the retraction size of the coronal plane was increased significantly and the fatty accumulation of the supraspinatus muscle had progressed significantly. Conclusions: Age is also a strong factor to affect the feature of RCT after the shoulder dislocation in patients over 40. And the delay of the MRI may deteriorate the degree of tear size and fatty degeneration.

목적 : 고식적 견관절 MRI 검사에 사각시상면 영상 추가 시 극상건 파열의 진단적 정확도가 증가하는지 관절경 수술 소견을 대비표준으로 삼아 알아보고자 하였다. 대상 및 방법 : 2011년 1월부터 2012년 12월까지 본원에서 견관절 MRI 검사를 하고 관절경 수술을 받은 121명의 환자를 대상으로 하였다. 두 명의 영상의학과 의사가 독립적으로 관상사면과 시상사면 영상을 이용하여 극상건 파열을 평가하고 4주후 사각시상면 영상을 추가하여 다시 판독하였다. 관절경 수술을 대비표준으로 이용하였다. 건 파열 진단의 민감도와 특이도는 McNemar test로 비교하였고 관찰자 간, 기술 간 일치도는 카파계수로 평가하였다. 결과 : 사각시상면 추가 시 고식적 견관절 MRI만 이용하였을 때 보다 극상건 전층 파열 진단의 민감도가 증가하였고, 부분 파열 진단의 민감도, 특이도, 정확도 모두 증가하였지만 통계학적으로 유의한 차이는 없었다. 관찰자간 일치도는 사각시상면을 추가하거나 하지 않았을 때 모두 높은 일치도를 보였다. 영상 소견과 관절경 수술 소견은 사각시상면 추가 시와 추가하지 않았을 때 모두 중등도의 일치도를 보였다. 결론 : 극상건의 전층 및 부분 파열 평가를 위해 고식적 MRI에 사각시상면 영상을 추가 시 기존의 영상면 만으로 평가하였을 때와 진단적 정확도에 의미 있는 차이는 없었다.

Purpose: The purpose of the present study was to evaluate the diagnostic efficacy of CT arthrography (CTA) in the assessment of various shoulder pathologies, compared with MR arthrography (MRA) and MRI with arthroscopic correlation. Materials and Methods: CTA in 84 patients, MRA in 70 patients, and MRI in 27 patients were obtained. A radiologist interpreted each image for 5 pathologies: Bankart, SLAP, Hill-Sachs lesion, full-thickness, and partial-thickness rotator cuff tear. Detailed arthroscopic reports were compared with CTA, MRA, and MRI. The sensitivity, specificity, predictive values, and accuracy were calculated. The agreement between each diagnostic modality and arthroscopy was calculated. Diagnostic efficacy was assessed by the areas under the receiver operating characteristic (ROC) curves. Results: The diagnostic values of all three imaging groups were comparable to each other for Bankart, SLAP, Hills-Sachs, and full-thickness cuff tear lesions, but those of CTA were lower than MRI and MRA for partial-thickness cuff tears. The areas under the ROC curves for CTA, MRA, and MRI were not significantly different for all pathologies, except for partial-thickness cuff tears. Conclusion: CTA was equally competent to MRA or MRI in demonstrating Bankart, Hill-Sachs lesions, SLAP, and full thickness rotator cuff tears but not as efficient in diagnosing partial thickness rotator cuff tears.

Objectives: There is no report on treatment of acute traumatic rotator cuff tear in Traditional Korean Medicine. We reported Traditional Korean Treatment for pain relief and better movement of acute traumatic rotator cuff tear. Methods: Shoulder MRI was used to confirm the diagnosis of tear of rotator cuff. The patient was treated with Traditional Korean Methods (Acupuncture, Herbal medicine, Pharmacopuncture) for 6 months. We evaluated the patient through VAS (Visual Analogue Scale), UCLA shoulder scale, ROM (Range of motion) and Shoulder MRI. Results: After 6 months of treatment, the patient's VAS was decreased whereas UCLA score and Shoulder ROM were increased. Rotator cuff tear was repaired on Shoulder MRI images. Conclusions: In acute traumatic rotator cuff tear, Korean Traditional Treatment is good method for pain relief and better movement.

자기공명 관절 조영술(Shoulder MR Arthrography)는 견관절(Shoulder joint) 의 복잡한 해부학적 구조에 관하여 정확한 영상평가를 진단하기 위해 시행 한다. 우리는 어께 상완골(Shoulder humerus) 의 다양한 position인 Neutral position, Internal rotation position, External rotation position 에 관하여 Shoulder joint의 해부학 적인 회전 변화가 견관절 자기공명(Shoulder MRI) 영상에 어떤 진단적 결과를 가져오는가에 대해 상호 비교 하였다. 또한 환자의 정확한 촬영자세 유지를 위해 촬영 보조기구를 만들었다. 이 보조기구는 Modeling 설계에 의해 우리가 직접 제작한 자기공명 견관절 조영술 보조 기구이다. 이 보조기구를 사용하여 촬영한 결과 다음과 같은 결론을 도출해 내었다. External rotation position 에 의한 Shoulder MRArthrography 검사가 Shoulder joint의 중요 해부학적 구조인 Biceps tendon, Supera-spiatus tendon, Sub-scapularis tendon, Labrum, Sub-acromial space 의 해부학적 평가에서 제일 적합하다는 진단적 평가를 얻었다.

Calcific tendinitis of the shoulder joint, also known as chemical furuncle of the shoulder, causes intense shoulder pain and usually occurs within 1-2 cm from the insertion of the rotator cuff. We experienced a rare case of calcific tendinitis in the posterosuperior labrum of the shoulder joint in a 39-year-old male patient who presented with severe pain and weakness in the right shoulder. Radiographs and magnetic resonance imaging (MRI) findings showed calcific tendinitis in the posterosuperior labrum of the shoulder joint. A 1-week attempt at conservative treatment failed, so the calcified deposit in the posterosuperior labrum was arthroscopically removed. The patient's symptoms were completely relieved, and satisfactory clinical outcomes were achieved. Postoperative follow-up X-ray and MRI showed no recurrence of calcific tendinitis.

Purpose: Urgent diagnosis and treatment of the septic arthritis is required. The purpose of this study is to review to correlate preoperative MRI findings with arthroscopic findings in septic arthritis of the glenohumeral joint. Materials and Methods: Eleven patients with acute septic arthritis of the glenohumeral joint were treated with combination of arthroscopic lavage, debridement, and systemic antibiotics. The arthroscopic staging of infection was made based on the modified criteria of $G\"{a}chter$ and five major findings of MRI were marked in each stage of septic shoulder. Results: Bone and cartilage erosion was the end stage finding and two patients with all five positive findings had failed with arthroscopic treatment. Reactive bone marrow edema was evident in the greater tuberosity. Joint effusion, synovial thickening and soft tissue edema were rather non-specific finding and presented in all stages of septic shoulder. Conclusion: Diffuse marrow edema with metaphyseal cyst formation in the preoperative MRI implied advanced stage of septic arthritis, which may fail with arthroscopic debridement.
