MRI MANIFESTATIONS OF EPIPHYSEAL INJURY OF KNEE JOINT IN ADOLESCENT

Objective To describe the MRI manifestation of epiphyseal injury in knee of teenagers and its value in the diagnosis of this condition. Methods The MRI of 18 teenagers with epiphyseal injury in knee were analyzed retrospectively. Results Distal femoral epiphysis injury was found in seven cases,according to Salter-Harris classification,there were three cases of SalterⅡ,and four of SalterⅢ;proximal tibial epiphysis injury in 10 cases,of which,three cases of SalterⅡ,and five of Salter Ⅲ;and two of Salter Ⅳ;one with avulsion fracture of patella belonged to SalterⅢ.Fracture lines and bone marrow edema were seen on MRI of all 18 patients;epiphyseal plate widening seen in 17;periosteal elevation or disruption observed in 11;ligament or meniscus injury appeared in 15;and nine with articular cavity hydrops.On plain film radiography of the 18 patients,the fracture lines were showed only in five cases,the fractures of the rest 13 were confirmed by MRI. Conclusion There are typical signs on MRI of teenagers with epiphyseal injury.MRI may help to discover this type of nondisplaced injury,and also conducive to diagnosis of damage of muscles and soft tissues.
