Objective To investigate the clinical value of CT in early diagnosis of bony Bankart lesion. Methods There were 26 emergency cases with a history of single osseous Bankart lesion in our hospital. They were not only taken the AP, axial and transthoracic X-ray,but also CT examination( slice thickness:3 mm) . The imaging diagnosis was independently determined by a radiologist and an orthopedist. Results There were only 11 cases with shoulder dislocation and without bony lesion among the AP and transthoracic X-ray examination of 26 cases, while CT examina-tion found all cases with bony lesion in various extent. Conclusions Bankart lesion can′t be diagnosed only by X-ray examination due to anatomical relation and size of fracture fragments, CT examination has more important value in early diagnosis of bony Bankart lesion.%目的：探讨CT在肩关节骨性Bankart损伤中早期诊断的应用价值。方法急诊收治26例单肩骨性Bankart损伤患者,除采用X线正位、轴位、穿胸位检查外,再予以CT检查,扫描层厚3 mm,并由1位影像科医师及1位骨科医师独立读片。结果26例患者中,X线正位及穿胸位片仅发现11例存在关节脱位,并未发现骨性损伤；而CT检查发现26例患者均出现不同程度的骨性损伤。结论 Bankart损伤由于其解剖位置、骨折片大小而导致单纯X线检查无法确诊,CT检查在骨性Bankart损伤的早期具有更好的辅助诊断作用。
