Early diagnosis of slipped capital femoral epiphysis on magnetic resonance imaging: A case report with review of literature

Slipped capital femoral epiphysis (SCFE) is a common hip condition occurring in adolescents, with a prevalence of 10 cases per 100,000 children. It usually affects younger age group from 10 to 17 years. The condition is usually found to be coexistent with various other conditions such as obesity, growth surges, and endocrine disorders such as hypothyroidism, growth hormone supplementation, hypogonadism, and pan-hypopituitarism. Patients present with limping and a poorly localized pain in the hip, groin, thigh, or knee. Diagnosis of the condition is often delayed due to its nonassociation with trauma and hence increases the chances of developing various complications such as avascular necrosis, chondrolysis and deformity. Majority of researches of SCFE are from Europe and North America, while studies in Asian populations are rare. Delay in diagnosis of SCFE is usually due to patients presenting with knee pain. Imaging can thus aid in early diagnosis and appropriate treatment of the disease, which in turn reduces incidence of deformity and disability in the affected children. Bilateral hip radiography - anteroposterior and frog′s-leg lateral views and magnetic resonance imaging (MRI) are the radiological techniques that help in early diagnosis. MRI detects early physeal changes of both preslip and SCFE even when radiographs and computed tomography are normal. MRI should be routinely used to diagnose early SCFE in preslip stage to avoid further complications
