What causes ponticulus posticus?
The ponticulus posticus is a bony bridge in the first cervical vertebra between the lateral mass and the posterior arch. It results due to ossification of the posterior atlanto-occipital ligament of atlas and encloses the vertebral artery and the first cervical nerve root .
What is Posticus?
adj. 1. Located behind a part or toward the rear of a structure. 2. Relating to the caudal end of the body in quadrupeds or the back of the body in humans and other primates.
What is Pons Ponticus?
A complete posticus ponticus is one continuous bridge that extends from the posterior aspect of the lateral mass to the anterior aspect of the posterior tubercle. A partial posticus ponticus is one that does not extend fully from the posterior lateral mass to the posterior tubercle.
What is posterior Ponticulus?
Ponticulus Posticus means “little posterior bridge” in Latin. It is defined as an abnormal small bony bridge which is formed between the posterior portion of the superior articular process and the posterolateral portion of the superior margin of the posterior arch of the atlas .
Is KFS hereditary?
KFS may occur as an isolated abnormality (Klippel-Feil anomaly) or as a syndrome with associated anomalies. In many individuals with KFS, the condition appears to occur randomly for unknown reasons (sporadically). In other cases, KFS may be inherited as an autosomal dominant or autosomal recessive trait.
What is block vertebrae?
Block vertebra is a type of vertebral anomaly where there is a failure of separation of two or more adjacent vertebral bodies. It is an anatomic variant.
What is Harris ring cervical spine?
Ring of Harris is a ring-like structure resulting from projection of the lateral masses of C2 on its body. Assess bony outlines for continuity. A fracture can be seen as a step in the ring outline.
What is an arcuate foramen?
The arcuate foramen is an anatomic variant that is thought to arise from ossification of the posterior atlanto-occipital membrane. Owing to potential entrapment of the vertebral artery segment that traverses the foramen, vertebrobasilar ischemia may occur, and the person may experience vertigo, headache, or neck pain.
What is lordosis of the cervical spine?
What is Cervical Lordosis? Cervical Lordosis refers to the natural curve of the spine in the neck, known as the cervical spine. From top to bottom, a healthy spine forms an “S” shape, with a healthy cervical spine forming a gentle “C” at the top.
Is Klippel Feil a disability?
Klippel-Feil Syndrome, a rare birth disability.
Is Klippel-Feil syndrome life threatening?
When Klippel-Feil Syndrome Is Serious. Some cases of KFS can become serious and potentially life-threatening in a few different ways: Cervical myelopathy.
What is ponticulus posticus?
Ponticulus posticus in Latin means ‘little posterior bridge’. Other synonyms for ponticulus are arcuate foramen, kimerle anomaly, retroarticular foramen and retocondylar foramen.
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).
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.
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.
