Bilateral Slipped Capital Femoral Epiphysis - A Rare Presentation of Primary Hypothyroidism

Slipped capital femoral epiphysis (SCFE) typically affects adolescents, characterized by the displacement of the femoral head from the neck at the hip joint.SCFE is uncommon beyond 15-17 years of age, as the proximal femoral physis typically closes by this time in boys.However, endocrine disorders like hypothyroidism, which delay physeal closure, can result in SCFE in adults.Primary hypothyroidism, characterized by insufficient thyroid hormone production, has other systemic effects with SCFE being unrecognized and a rare presentation.This case report aims to present a rare occurrence of bilateral SCFE in the context of primary hypothyroidism.We present the case of a 19-year-old boy who initially presented with symptoms of bilateral hip pain and limited mobility.Diagnostic evaluation revealed concurrent primary hypothyroidism, confirmed through thyroid function tests.Subsequent imaging confirmed the presence of bilateral slipped capital femoral epiphysis.The patient received appropriate thyroid hormone replacement and is planned for surgical intervention for SCFE.This case highlights the importance of considering underlying endocrine disorders, such as primary hypothyroidism, in the differential diagnosis of atypical presentations of SCFE.Further research is needed to understand the exact pathophysiological mechanisms by which primary hypothyroidism causes bilateral SCFE.
