Cleidocephaly

Cleidocephaly is a rare skeletal dysplasia characterized by underdeveloped or absent clavicles. The term originates from the Greek words "kleis" (collarbone) and "kephale" (head). Individuals with cleidocephaly may have unusually mobile or narrow shoulders, which can sometimes meet in the front of the chest. This condition is often discovered incidentally on X-rays due to the absence or significant hypoplasia of the clavicles.

In some cases, cleidocephaly can be associated with other skeletal abnormalities, though it is not always accompanied by significant health problems. The degree of clavicular involvement can vary, ranging from mild underdevelopment to complete absence. The genetic basis for cleidocephaly is not fully understood, and it can occur as an isolated finding or as part of a syndrome.

Diagnosis is typically made through radiographic imaging. Treatment, if necessary, focuses on managing any functional limitations or cosmetic concerns related to the shoulder structure. However, many individuals with cleidocephaly experience no functional impairment and live normal lives without requiring specific medical intervention. The prognosis for cleidocephaly is generally good, with no significant impact on lifespan or overall health in most instances.
