Seven adults with painful effusions of the knee were examined for occult fractures using pluridirectional tomography in the coronal and lateral planes. Six patients (ages 50-82 years) were osteopenic and gave histories ranging from none to mild trauma; one 26-year-old man was not osteopenic and had severe trauma. In all cases, routine radiographs were interpreted as negative, but tomography demonstrated a fracture. Five fractures were subchondral. Bone scans in 2 patients were positive. The authors conclude that osteopenic patients with a painful effusion of the knee should be considered to have an occult fracture. While bone scans may be helpful, tomography is recommended as the procedure of choice to define the location and extent of the fracture.
对7例膝关节疼痛性积液的成年人进行了冠状面和侧面多向断层扫描以检查隐匿性骨折。6例患者（年龄50 - 82岁）存在骨质减少，受伤史从无到轻度外伤不等；1例26岁男性无骨质减少，有严重外伤史。所有病例中，常规X线片解读为阴性，但断层扫描显示有骨折。5处骨折为软骨下骨折。2例患者的骨扫描呈阳性。作者得出结论，膝关节疼痛性积液的骨质减少患者应被视为存在隐匿性骨折。虽然骨扫描可能有帮助，但推荐使用断层扫描作为确定骨折位置和范围的首选检查方法。
