Abifid ribis acongenital abnormalityof therib cageand associated muscles and nerves which occurs in about 1.2% of humans. Bifid ribs occur in up to 8.4% ofSamoans.[1]Thesternalend of the rib is cleaved into two. It is usuallyunilateral.[2]
Bifid ribs are usuallyasymptomatic,and are often discovered incidentally bychest X-ray.Effects of this neuroskeletal anomaly can includerespiratorydifficulties,neurologicaldifficulties, limitations, and limited energy from the stress of needing to compensate for theneurophysiologicaldifficulties. An unstable bifid rib may lead toslipping rib syndrome.[3]
Another association is withodontogenic keratocystsof the jaw, which may behave aggressively and have a high propensity to recur when treated with simple enucleation and curettage. When seen together, the patient is likely to havenevoid basal-cell carcinoma syndrome(Gorlin-Goltz syndrome).
