Summary

Elderly patients with odontoid fractures, often type II, may not benefit from aggressive surgical union. Osteopenia and falls are common causes, with outcomes depending on neurological status.

Area of Science:

  • Orthopedic Surgery
  • Geriatric Medicine
  • Traumatology

Background:

  • Odontoid fractures are serious injuries, particularly in older adults.
  • Understanding fracture patterns and contributing factors in the elderly is crucial for effective management.

Purpose of the Study:

  • To analyze the characteristics and outcomes of odontoid fractures in patients over 60.
  • To evaluate the role of osteopenia and common injury mechanisms.
  • To assess the efficacy of surgical union and arthrodesis in this demographic.

Main Methods:

  • Retrospective review of 35 patients aged over 60 with odontoid fractures.
  • Analysis of fracture patterns (Anderson and D'Alonso classification), injury mechanisms, and displacement.
  • Assessment of primary union rates, spinal cord injury incidence, and long-term outcomes.

Main Results:

  • Type II odontoid fractures were most common (82%), often caused by domestic falls (53%).
  • Posterior displacement occurred in 88% of type II fractures; primary union was achieved in only 23%.
  • Older patients had a higher incidence of spinal cord injury; neurological status determined outcomes.

Conclusions:

  • Osteopenia is a likely contributing factor to odontoid fractures in the elderly.
  • Aggressive surgical attempts for primary union or arthrodesis in non-union may not be warranted for most elderly patients.
  • Management should prioritize neurological status and consider patient-specific factors over aggressive surgical intervention.
