探讨低场磁共振在膝关节隐性骨折诊断中的应用价值。
Objective to investigate the value of low field MR imaging in detecting occult fractures.
结论膝关节隐性骨折或外侧部隐性骨折作为ACL损伤的间接征象是可靠的。
Conclusion Occult fracture of the knee or of the lateral compartment of the knee is a reliable indirect sign associated with ACL tears.
胫骨外侧平台后缘和股骨外侧髁的“对吻骨挫伤”和胫骨髁间前区隐性骨折，提示ACL损伤。
The "kissing contusion"of occult fracture situated in the LFC and the PLTP, and occult fracture of the anterior intercondylar area are suggestive of ACL tear.
结果发现隐性骨折病灶110处，根据损伤累及的范围和程度，隐性骨折分为隐性皮质下骨折、隐性骨皮质骨折和隐性骨软骨骨折三型；
Results 110 lesions were found and were divided into 3 types: occult subcortical fracture, occult cortical fracture and occult osteochondral fracture according to the range and degree of injuries.
结论CT重建，立体显示膝关节骨损伤状况，能间接提示交叉韧带损伤，MRI则对韧带及关节软骨、半月板损伤及隐性骨折显示较佳。
Conclusion ct reconstruction can show knee joint trauma three-dimensionally which can refer to cross ligament trauma indirectly and MRI can show ligament, joint cartilage and meniscus more clearly.
