Assessment of anterior shoulder instability by CT arthrography

Computed tomography (CT) immediately after double-contrast shoulder arthrography was taken in twenty-two young male patients with anterior shoulder instability including recurrent dislocation and subluxation. This recently developed technique called CT arthrography can provide significant information about patients with glenohumeral instability which is difficult to obtain by conventional arthrography. Information about glenoid labrum pathology is useful for proper management of the shoulder with instability. Lesions identified in this study include anterior labral defects (attenuation, tear, displacement), anterior capsular distension and/or detachment, Hill-Sachs lesion, anterior glenoid rim compression fracture, and fracture of scapula. This article describes the method used in CT arthrography of the glenohumeral joint, reviews the normal cross-sectional anatomy, and emphasizes the importance of the application of CT arthrography in the shoulder disorder with instability. CT arthrography of the glenohumeral joint is easy to perform, is accurate, and has lower radiation dose than arthrotomography.

Chondroma of Soft Tissue: A Case Report / 대한정형외과학회잡지

A case of chondroma of soft tissue of right hand in 23-year old man was reported. The presenting symptom was a slow growing mass, causing mild tenderness. Radiologic examination revealed a well demarked and lobulated calcified mass, was located extraskeletally. Specimen exised from soft tisssue of the hypothenar area of the hand was 5×4×3.5cm sized mass, had gelatinous and gray-whitish appearance. On microscopical examination, the tumor was classified as a chondroma of soft tissue.
