title: Pseudohypoparathyroidism as a rare cause of bilateral slipped capital femoral epiphysis.
abstract: Slipped capital femoral epiphysis (SCFE) is a disorder of adolescent age. Presentation of SCFE earlier than the expected age range should prompt the clinician to consider the presence of an underlying endocrinopathy. Early recognition and aggressive management of the predisposing endocrine disorder is crucial to prevent treatment failure and associated morbidity. We report the clinical presentation and treatment of an 8-year-old girl with bilateral slipped capital femoral epiphysis. The unusual age, persistent hypocalcemia, and associated distal femoral physeal deformities prompted further evaluations, which led to the diagnosis of pseudohypoparathyroidism type 1b. PHP type 1b is an extremely rare cause of SCFE and only a few cases have been reported. A delay in diagnosis in such case is not uncommon.
