Results
Ponticulus posticus was observed in 12.55% of the patients,
with a slight female (53.44%) predominance.
Incomplete bony outgrow was present in 51.72% of the cases.
The prevalence of incomplete ponticulus posticus was higher in female patients (63.33%).
When ossification was incomplete,
the defect was mostly found at the anterior margin (70%),
although incomplete ossification may be found at any point in the arch.
The rest of 48.27% of the patients had a complete arch,
with a male domination (57.14%).
Bilateral complete foramen was seen in 10.34% of the cases,
4 of them being female and 2 being male patients.
The highest incidence was in the group between 40 and 49 years (30.76%).
The youngest patient who presented ponticulus posticus was 9 years old and the oldest patients in our study was 78 years old.
There was a variation in size,
configuration and position of the bony arch.
Some of the patients presented an incomplete and sometimes difficult to recognize arch,
while other patients had a thick and amorphous bony outgrow.
The sulcus of the vertebral artery also varied widely.
