Area of Science:

  • Orthopedics
  • Radiology
  • Pathology

Context:

  • Osteonecrosis, or bone death, stems from varied causes.
  • Trauma, cortisone, hemoglobinopathies, and metabolic diseases are known associations.
  • Idiopathic osteonecrosis occurs without identifiable causes.

Purpose:

  • To review the causes, pathogenesis, and diagnostic advancements in osteonecrosis.
  • To highlight the role of Magnetic Resonance (MR) imaging in diagnosis and staging.

Summary:

  • Intraosseous vascularization is a common pathway for osteonecrosis.
  • Prognosis depends on patient age, necrosis location, and disease stage.
  • Modern imaging, particularly MR imaging, enhances early diagnosis and staging.

Impact:

  • Improved diagnostic accuracy through MR imaging.
  • Facilitates timely and adequate therapeutic interventions.
  • Enhances understanding of osteonecrosis pathogenesis and influencing factors.
