Area of Science:

  • Orthopedics
  • Hematology
  • Pathology

Background:

  • Nontraumatic osteonecrosis is increasingly understood to stem from intravascular coagulation within the bone's microcirculation.
  • This coagulopathy, affecting capillaries and venous sinusoids, can lead to venous thrombosis and arterial occlusion.

Purpose of the Study:

  • To elucidate the underlying etiologic risk factors that activate the coagulopathy leading to nontraumatic osteonecrosis.
  • To provide a comprehensive overview of conditions triggering intravascular coagulation in this context.

Main Methods:

  • Literature review and synthesis of existing research on osteonecrosis and thrombophilia.
  • Analysis of etiological factors implicated in intravascular coagulation and their link to bone necrosis.

Main Results:

  • Intravascular coagulation is identified as the intermediary event causing nontraumatic osteonecrosis.
  • Numerous risk factors are identified, including familial thrombophilia, hyperlipemia, hypersensitivity reactions, infections, and tissue factor release.

Conclusions:

  • Nontraumatic osteonecrosis is a consequence of intravascular coagulation, always initiated by specific underlying risk factors.
  • Understanding these triggers is crucial for preventing and managing osteonecrosis.
