The Kallmann's syndrome is characterized by low plasma gonadotropin and gonadal steroid concentrations and appears to be due to a deficiency of the gonadotropin-releasing hormone, as was first described by Kallmann et al. in 1944. The hypogonadotrophic hypogonadism results in absent or incomplete pubertal development and may be associated with inherited abnormalities such as anosmia, cleft palate and lip, color blindness, craniofacial deformities, renal agenesis, neurosensory deafness and musculoskeletal deformities. The clinical association between slipped capital femoral epiphysis and endocrine disease is well known, but there were few cases that actually occur with human endocrine disorders. We experienced a case of the slipped capital femoral epiphysis associated with Kallmann's syndrome in a 18 years old female, which was treated successfully by using two ASNIS screws and a brief review of literature was made.
