Abstract
Foramen Magnum is the largest foramen in the posterior cranial fossa. It is the transistion zone between spine and skull . It plays an important landmark because of its close relationship to key structures such as brain, spinal cord and vertebral arteries. The shape and size of (APD and TD) of foramen magnum is important parameter as many vital and vulnerable structures pass through it and could be compressed in FM achondrplasia, FM brain herniation and atlanto‐ occipital fusion. Thus the present study was conducted to know the variations in shape and size of FM in North Karnataka region. Forty five dry adult human skulls of unknown age and sex were examined in the Department of Anatomy, Mahadevappa Rampure Medical College, Kalaburagi. Shape, APD and TD of foramen magnum recorded. The measurements were carried out using vernier calipers. Data collected was statistically analysed. Majority of the foramen magnum were oval in shape 28 (62.22%), followed by round 11 (24.44%), tetragonal 3 (6.67%) and pentagonal 3(6.67%). Min APD was 31mm max38mm, Min TD‐25mm, max32mm, min FM index 1.03 and max 1.23. Mean+/‐SD of APD was 33.53mm+/‐2.36mm, Median APD‐33mm. Mean+/‐SD of TD was 29.13mm+/‐1.96mm, Median TD‐ 29mm. Mean+/‐SD of FM index was 1.15+/‐0.079 and Median index was 1.14. The present study will help posterior and lateral approaches to the craniovertebral junction by neurosurgeons and orthopaedician of this region. Prior morphometric knowledge helps to prevent inadvertent complications such as haemorrhage, atlantooccipital instability and injury to major structures passing through foramen magnum.
