Osteopetrosis (Albers-Schonberg's disease, Marble bones, and chalk bones) is a rare genetic disorder in which the bony structure throughout the body becomes dense and brittle. Because of the fragility of the pathologic bone, fractures are common and insufficient development of the bone marrow, optic atrophy, deafness, and facial paralysis can be developed to complications. We report a case of 35-year-old female with the autosomal dominant form of osteopetrosis combined with subtrochanteric fracture of femur that underwent surgical treatment.
