Sutural bones (Wormian bones) are small accessory bones that develop within the cranial sutures, particularly the lambdoid suture, from additional ossification centres. They are present in approximately 50 to 60 percent of normal individuals with fewer than 10 bones and are numerous (10 or more) in conditions associated with abnormal skull ossification including osteogenesis imperfecta, hypothyroidism, cleidocranial dysostosis, and Menkes kinky hair disease.
Numerous Wormian bones (10 or more) in an infant skull radiograph should prompt investigation for osteogenesis imperfecta (blue sclerae, easy fractures), hypothyroidism, or other metabolic bone conditions. In the forensic context, Wormian bones are a skeletal marker that can persist through decomposition and be used for ancestry determination in skeletal analysis.
