The cause is usually a developmental abnormality arising in the early prenatal period, typically failure of obliteration of the second, third, and fourth branchial cleft, i.e. failure of fusion of the second branchial arches and epicardial ridge in lower part of the neck. Branchial cleft cysts account for almost 20% of neck masses in children. [1]
As a result of having congenital Klippel-Feil syndrome, the spinal anatomy of the individual will present abnormal fusion of any two of the seven cervical bones in the neck. [13] This is considered to be an anomaly of cervical bones. [14] It affects the functioning of cervical spinal nerves (C1 - C8) because of compression on the spinal cord.
A neck mass or neck lump is an ambiguous mass found in the neck area. There are many different possible causes, [1] including head and neck cancer [2] and congenital conditions like branchial anomalies and thyroglossal duct cysts. [3]
A common sign is a neck growth. It may be found at birth, or discovered later in an infant after an upper respiratory tract infection. [8] Cystic hygromas can grow very large and may affect breathing and swallowing. Some symptoms may include a mass or lump in the mouth, neck, cheek, or tongue. It feels like a large, fluid-filled sac.
A Jefferson fracture is a bone fracture of the anterior and posterior arches of the C1 vertebra, [1] though it may also appear as a three- or two-part fracture. The fracture may result from an axial load on the back of the head or hyperextension of the neck (e.g. caused by diving), causing a posterior break, and may be accompanied by a break in other parts of the cervical spine.
Retrocollis is the extension of the neck (head tilts back) and uses the following muscles for movement: bilateral splenius, bilateral upper trapezius, bilateral deep posterior paravertebrals. This is the "chin-in-the-air" version. A combination of these head positions is common; many patients experience turning and tilting actions of the head. [10]
These anomalies are observed in about 3.5 percent of people, and it is usually bilateral but can be unilateral or incomplete (ipsilateral or contralateral rudimentary facets) as well. Although sacralization may be a cause of low back pain , it is asymptomatic in many cases (especially bilateral type).
Radioulnar synostosis is a rare condition where there is an abnormal connection between the radius and ulna bones of the forearm. [1] This can be present at birth (), when it is a result of a failure of the bones to form separately, or following an injury (post-traumatic).
