How common is ponticulus posticus?
The prevalence of ponticulus posticus in the Northeast population was 22.5%. This study proposes a CT-based classification system for ponticulus posticus. The most common subtype was the CC subtype, complete bony arch on right and left sides comprising 25% of all patients with a ponticulus posticus.
Where is the arcuate foramen found?
In human anatomy, arcuate foramen, also known as ponticulus posticus (Latin for “little posterior bridge”) or Kimmerle’s anomaly, refers to a bony bridge on the atlas (C1 vertebra) that covers the groove for the vertebral artery.
What is high riding vertebral artery?
A high-riding vertebral artery (HRVA) is an intraosseous anomaly that narrows the trajectory for C2 pedicle screws. The prevalence of a HRVA is high in patients who need surgery at the craniovertebral junction, but reports about HRVAs in subaxial cervical spine disorders are limited.
What is a congenital block vertebra?
Block vertebra is a congenital failure of segmentation of somites. May be partial or complete involving anterior and/or posterior elements. May demonstrate a decreased anteroposterior vertebral body diameter. Usually asymptomatic.
What is foramen Arcuale?
OBJECTIVE The foramen arcuale (FA) is a bony bridge located over the vertebral artery on the posterior arch of the atlas. The presence of an FA can pose a risk during neurosurgery by providing a false impression of a broader posterior arch.
How do you fix Sacralization?
Treatment for Sacralization
- Lifestyle modifications to avoid or change activities that increase pain.
- Over the counter (OTC) pain medication, as directed.
- Physical therapy.
- Periodic treatment, such as steroid injections to reduce symptoms.
What is “ponticulus posticus?
Ponticulus posticus, also referred to as arcuate foramen or Kimmerle’s anomaly, is what it’s Latin name implies, “Ponticulus posticus,” a “little posterior bridge.” How did you develop this bony little bridge abnormality at the posterior of the atlas/C1 vertebra? In simplest terms, the little bony bridge is a petrified ligament.
Is the ponticulus posticus associated with chronic tension headaches and migraines?
The goal of this study was to substantiate whether the ponticulus posticus was the possible cause of chronic tension-type headaches and migraines. Complete Ponticulus Posticus – bilateral – both sides The researchers examined five hundred patients for the presence and type of ponticulus posticus.
What are the possible complications of ponticulus posticus failure?
Failure to detect ponticulus posticus can have grave complications during cervical spine surgical intervention, especially those requiring screw placement in lateral mass region of Atlas vertebra 1).
Can ponticulus posticus be missed on X-rays?
Ponticulus posticus can be missed on x-rays and even digital motion x-ray (DMX) and often it’s just discarded as kind of a normal variant. In our office, we see ponticulus posticus in some patients. For many of them, this is not a normal variant but the cause of many of their problem symptoms.
