Interparietal bone (Os Incae) in craniosynostosis. The squamous portion of the occipital bone consisting of the interparietal part is sometimes divided by a transverse suture in the position of the highest nuchal line and is called as Os Inca. The interparietal portion may remain separated from the supraocciptal by a suture; it is then called the interparietal or Inca bone [2]. The squamous part of occipital bone consists of two parts, supraoccipital and interparietal. The interparietal bone, Os Incae, is formed in a persistent mendosal suture. @article{871457f79b544cbe931bd698336e191e. We report 11 children with craniosynostosis in the presence of an interparietal bone, five from Children's Hospital at Montefiore and six children from Children's Hospital Boston. Wu, J. K., Goodrich, J. T., Amadi, C. C., Miller, T., Mulliken, J. The “one-element interparietal” is interpreted as the fusion of all four elements (two medial and two lateral interparietal elements) into one median bone. These Inca bones may give a false appearance of fracture on Roentgenographs. Many variations of interparietal bone have been reported by many investigators. June K. Wu, James T. Goodrich, Chiemezie C. Amadi, Todd Miller, John B. Mulliken, Alan L. Shanske, Research output: Contribution to journal › Article › peer-review.

Medical definition of interparietal bone: a median triangular bone lying at the junction of the parietal and occipital bones and rarely present in humans but conspicuous in various lower mammals —called also interparietal. In one study of 500 adult Indian skulls (Singh, et al.) Occurrence of Inca bones is rare as compared to other inter sutural bones such as wormian bones. The true incidence of an interparietal bone in patients with craniosynostosis or craniofacial anomalies is not known; nor are there recognized sequelae of an interparietal bone (bathrocephaly). The Inca bone is one of the Wormian bones. After the formation of the second interparietal bones, more-over, one or more additional centres for the pre-interparietal bone appearat the region of the lambda, forming a triangular region (Matsumura et al. The true incidence of an interparietal bone in patients with craniosynostosis or craniofacial anomalies is not known; nor are there recognized sequelae of an interparietal bone (bathrocephaly). Looking for interparietal bone? It is homologous to the postparietal bones of other animals. It looks like a multiangular insertion. Description An interparietal bone (os interparietale or Inca bone) is a dermal bone situated between the parietal and supraoccipital. This suture is a normal variant in the human skull, well‐known in anatomy and radiology textbooks. os Incae laterale sinistrum, most probably was formed through a faulty fusion between the left lateral part of the secondary interparietal pair of centres [16] or left lateral nucleus of the second pair [31] and the remaining interparietal. Wu, June K. ; Goodrich, James T. ; Amadi, Chiemezie C. ; Miller, Todd ; Mulliken, John B. ; Shanske, Alan L. /. It is common and a normal variant.

Hypotheses regarding mechanisms that may contribute to the formation of an interparietal bone are discussed. The interparietal bones fuse with the parietal bones in marsupials and sirenia (sea cows). It corresponds to the upper portion of the squama of the occipital bone that lies superior to the highest nuchal line and is completely fused to the supraoccipital. title = "Interparietal bone (Os Incae) in craniosynostosis". Interparietal bone is formed due to failure of fusion of these centres and/or their nuclei with each other. The interparietal forms more of a shelf in non-human primates and earlier hominids (Srivastava, 1992). AB - The interparietal bone, Os Incae, is formed in a persistent mendosal suture.
