作者对由MRI发现的25例急性前十字韧带(ACL)撕裂的病人的X线平片作了回顾性评价,用以观察有关的骨损伤。具有下列MR征象者诊断为急性ACL撕裂:ACL前缘波浪状外形及ACL崩裂、ACL束的局限或弥慢性高信号、以及髁间切迹软组织水肿。所有MR图象均由0.5T设备获得。研究组是25例(25个膝部)符合规定标准的病人,年龄17岁～46岁(平均28岁)。男16例,女9例。ACL损伤到MR和X线平片检查之间的平均时间为17天(0
The authors retrospectively evaluated radiographs of 25 patients with tearing anterior cruciate ligament (ACL) tears by MRI to observe the associated bone lesions. Patients with the following MR signs were diagnosed with acute ACL tears: wavy ACL shape and ACL-cracking, ACL-confined or amethyroidism, and intercondylar notch soft tissue edema. All MR images are acquired by a 0.5T device. The study group consisted of 25 patients (25 knees) who met the prescribed criteria and were 17 to 46 years (mean, 28 years). 16 males and 9 females. The mean time between ACL injury and MR and plain radiography was 17 days (0
