Osteonecrosis of the Femoral Head and Hip Arthritis in an Adolescent Following an Isolated Fracture of the Greater Trochanter: A Case Report and Review of the Literature.

To our knowledge, 19 other cases of isolated fractures of the greater trochanter in adolescents have been reported since 1905. All high-energy injuries (10 cases) progressed to osteonecrosis, independent of the intervention; none of the low-energy cases progressed to osteonecrosis. We advocate vigilance and early magnetic resonance imaging for these injuries to detect and treat osteonecrosis in its early stages.
