title: Multimodality treatment of a complex series of parallel pathologies in a 16-year-old male that ultimately leads to bilateral hip arthroplasty surgery: A case report.
abstract: BACKGROUND
  Femoral head osteonecrosis is associated with significant sequelae for the patient in the long-term. A combination of factors are thought to contribute to the pathophysiology behind this debilitating disease process.
  
  
  METHODS
  We report on a 16-year-old adolescent male requiring staged bilateral hybrid hip arthroplasty within 3years of diagnosis of acute lymphoblastic leukaemia that ran a complicated course of multimodality treatment.
  
  
  CONCLUSIONS
  The case examines the literature on femoral head osteonecrosis in this population cohort and the challenge for the orthopaedic surgeon in the management of this increasingly prevalent condition.
  
  
  CONCLUSIONS
  In a young population cohort, it is important to have arthroplasty surgery as part of the management armamentarium, especially when coupled with complex pathology.
