Alterations occur in the radiological appearance of the soft tissues after injury to the elbow joint. These are due to displacement of the intra-articular fat pads by capsular distension when an effusion is present. A prospective study of 89 consecutive elbow injuries was undertaken in an attempt to assess the usefulness and reliability of these changes in the diagnosis of minor elbow injuries and the assessment of their clinical progress. In 61 elbows (69 per cent) there was no radiological evidence of an effusion and no evidence of bony injury. All quickly returned to normal. In 28 elbows (31 per cent) radiological evidence of an effusion was present. Twenty-three (80 per cent) of these were also found to have a fracture in, or adjacent to the elbow joint. In 9 elbows the fracture could not be seen on the initial radiographs. Because of the presence of an effusion, repeat radiographs were taken and a fracture discovered. The presence of an effusion was associated with an increase in the time required for full recovery.
肘关节受伤后，软组织的放射学表现会发生改变。这是由于存在积液时，关节囊扩张导致关节内脂肪垫移位所致。对89例连续的肘部损伤进行了一项前瞻性研究，旨在评估这些变化在诊断轻度肘部损伤及其临床进展评估中的有用性和可靠性。61例肘部（69%）没有积液的放射学证据，也没有骨损伤的证据。所有患者均迅速恢复正常。28例肘部（31%）有积液的放射学证据。其中23例（80%）还被发现肘关节内或其附近有骨折。9例肘部在最初的X线片上未见骨折。由于存在积液，进行了重复X线检查并发现了骨折。积液的存在与完全恢复所需时间的增加有关。
