Abstract
The basiocciput of 265 Indian adult human skulls was examined for prec ondylar tubercles, which are single or paired osseous formations anter ior to the occipital condyles and foramen magnum. Of the 14% of skulls displaying these tubercles unilaterally or bilaterally, 5.3% demonstr ated ridges, 4.9% showed spines and 3.8% exhibited processes. Sexual d imorphism was evident with female skulls showing a higher incidence (8 .7%) compared with male skulls (5.3%). The corresponding atlas vertebr ae were normal. These craniovertebral anomalies may have clinical rele vance for lesions at the foramen magnum.
