Area of Science:

  • Anatomy
  • Surgical Anatomy
  • Craniometry

Background:

  • The occipital condyle connects the cranium and vertebral column.
  • Advancements in neuroimaging increase interest in craniovertebral surgery.
  • Accurate anatomical knowledge of the craniovertebral junction is vital for surgical success.

Purpose of the Study:

  • To conduct a morphometric analysis of the human occipital condyle.
  • To provide detailed anatomical data for craniovertebral junction surgery.

Main Methods:

  • Morphometric analysis of 27 parameters on 404 occipital condyles from 202 dry skulls.
  • Measurements included condyle dimensions, distances to the hypoglossal canal, and angles.
  • Classification of occipital condyle shapes into eight distinct types.

Main Results:

  • Occipital condyle dimensions: length (23.4 mm), width (10.6 mm), height (9.2 mm).
  • Intercondylar distances: anterior (21.0 mm), posterior (41.6 mm); sagittal angle: 59.3 degrees.
  • Eight distinct condyle shapes identified, with oval-like (Type 1) being most common (50%) and two-portioned (Type 7) most rare (0.8%).

Conclusions:

  • Occipital condyles exhibit significant variability in shape, size, and orientation.
  • Preoperative radiological assessment is essential for craniovertebral junction surgery.
  • Detailed morphometric data aids in planning and executing safer surgical interventions.
