True or false: Focal periphyseal oedema zone relates to mechanical strain placed on the physis during physeal closure.
True. FOPE zone are identified in adolescents around the time of expected skeletal age of maturation and likely relates to the early stages of physiologic physeal fusion.
True or false: Physeal closure starts peripherally and proceeds centrally increasing the susceptibility of the central area to trauma.
False: Physeal closure starts centrally and proceeds peripherally. The central portion of the physis has increased susceptibility to trauma, which is believed to be due to decreased elasticity of the central physis relative to the periphery during the early closure of the central physis . This decreased elasticity could also potentially predispose the central physis to increased stress during physeal closure.
True or false: Focal periphyseal oedema zone is always associated with trauma in the affected region.
False: Clinically, patients may present with pain, with or without a history of acute injury.
True or False: Plain radiograph may be helpful in the diagnosis of a FOPE zone.
False: Plain films are unremarkable. These are best seen on MRI.
True or False: Focal periphyseal oedema always results in pain of the affected region.
False: May be asymptomatic.
There is a centrally located area of hypointense signal on T1W which showed marrow oedema signal intensity radiating outward from the physis into the distal femoral metaphysis on fluid sensitive sequences. Finding consistent with focal periphyseal oedema zone
Minimal joint effusion is seen.
