RESUMO
Hip fractures are uncommon in childhood and adolescence. A high-energy injury is the most common cause. Low-energy trauma may result in a pathological hip fracture or stress fracture of the femoral neck, on the grounds of a preexisting skeletal disease, a tumor, or a tumor-like lesion. Surgical or conservative treatment may be provided based on underlying disease and/or age, Delbet and/or Colona classification, and displacement of the fracture. We present a case series of 13 children with pathological hip fracture. Mean age of patients was 7 years, and average follow-up was 3 years. There were types I and II, 3 type III, and 10 type IV fractures according to Delbet/Colona classification. Patients were treated conservatively, by open reduction and internal fixation or by minimally invasive surgery. In 11 children (84.5%), the outcome was satisfactory; one child (7.75%) presented with nonunion and refracture after minimally invasive surgery, and another (7.75%) presented with refracture after conservative treatment. Both patients were treated with open reduction and internal fixation. Pathological hip fractures are rare in children and should be treated properly. Surgical treatment with open reduction, internal fixation, and bone grafting is preferred in displaced fractures. In nondisplaced fractures, the choice between conservative and surgical treatment should be based on Delbet/Colona classification and patient profile.
