Abstract
Epiphysiolysis is a relatively common disease in the adolescent population (9-16 years); however, it is rare in the adult population. It is characterized by non-traumatic proximal femur slipping. When it occurs in this population it is associated with some disease that slows sexual development and physis closure, such as endocrine diseases or brain tumors. The aim of the present study is to report a case of epiphysiolysis in a 22-year-old patient with hypogonadotropic hypogonadism. There are only 63 cases reported in the world literature on epiphysiolysis in the adult population.
