Wormian bones are those bones which found in the cranium having no regular relation to their normal ossification centres. They may be deceived for a fracture skull. The present study was conducted to evaluate the percentage of skulls where wormian bones were present, b anatomical distribution of wormian bones, side specific distribution of wormian bones, and range of observed wormian bones. Materials and Methods: The present study was conducted in the Department of Forensic Medicine in Government Medical College of Southern Haryana over a period of one year from January 2019 to December 2019. A total number of 130 cases brought for postmortem examination were studied. 86 male and 44 female dead bodies were studied. Location of wormian bones along the coronal, sagittal and lambdoid suture on ectocranial surface was noted. Results: The overall incidence of wormian bones was 20.78%. 19 wormian bones (14.62%) were observed in males and 8 (6.15%) in females. Wormian bones were most commonly located in lambdoid suture that is in 19 (14.62%) cases. Out of 19 wormian bones observed around lambdoid suture, 11 (57.90%) were found on left half of the skull and 3 (15.79%) were on right half of the skull. Conclusion: Knowledge of wormian bones is clinically important for forensic experts, neurosurgeons and radiologists because many a time's wormian bones may be misinterpreted for fractures in head injuries. The knowledge of wormian bones may help the doctors in their daily practice in timely diagnosis and management of diseases or fractures in relation to the wormian bones.

“…The Indian population is quite varied and it is no surprise that the reported sutural bone incidence from the Indian population is quite varied too. William F. Masih [16] , from his study in Rajasthan, reported a incidence of 4.7%. On the other hand, Muralimanju BV et al, [17] who also studied dry skulls from the Indian population, reported a incidence of 73.1%.…”

Background: Sutural bones are supranumary bones occurring along the sutures and completely surrounded by sutures of the skull. Their number, morphology and location in skull vary in skulls. The knowledge of these bones is imperative in surgery, medicolegal cases involving child abuse or fracture of skulls and for anthropologic identification of human populations. This study was undertaken to examine incidence and pattern of distribution of sutural bones in dry skulls from Eastern India and compare the findings with similar studies across the world.Materials and Method: 180 dry crania were identified as male or female skulls and studied for the incidence and pattern of distribution of sutural bones. Also the Cephalic Index was measured for finding its correlation with the number of sutural bones appearing in a skull.Results: 124 skulls were identified as male and 56 as female skulls. Overall incidence of sutural bone occurrence was found to be 72.28% which was essentially similar across sexes. The most common sites for sutural bones, in descending order of occurrence, were found to be parieto-occipital suture, asterion, pterion and lambda. Bregma was the least common site where no sutural bone was encountered. A highly statistically significant finding was in regard to laterality of sutural bone occurrence. Sutural bones occurring along coronal, parietotemporal, parieto-mastoid, occipito-mastoid sutures and pterion exhibited more than 80% tendency towards unilateral occurrence while those occurring at asterion exhibited around 70% tendency towards unilateral occurrence. All these findings, although displayed variable degree of sexual dimorphism, were statistically insignificant for variation among sexes. No correlation between the number of sutural bones with cephalic index was found. Conclusion:The findings of this study are in agreement with the findings of many similar suitably powered studies across the world.

“…This may be the reason that the reported sutural bone incidence from study of dry crania is quite varied too. For example, William F. Masih [15], from his study of dry crania, reported an incidence of 4.7% while Muralimanju BV et al, [16] who also studied dry skulls reported the incidence to be 73.1%. Therefore, to compare our results with the study on dry crania would be meaningless.…”

Background: Sutural bones are supranumary bones occurring along the sutures and completely surrounded by sutures of the skull. Their number, morphology and location vary in skulls. The knowledge of these bones is imperative in surgery, medicolegal cases involving child abuse or fracture of skulls and for anthropologic identification of human populations. The studies on sutural bones have traditionally been based on the studies of dry calvaria which are unreliable for the homogeneity of the population studied. Hence, this pilot study was undertaken to evaluate the feasibility of 3D volume rendering of CT scan data for study of sutural bones.Method: 3D volume rendering from 64-slice CT scan data from 64 patients was studied for incidence and location of occurrence of sutural bones.Results: Overall incidence of sutural bone occurrence was found to be 29.69%. The most common sites for sutural bones, in descending order of occurrence, were found to be parieto-occipital suture, asterion, and lambda. Conclusion:Sutural bone studies in concurrent populations such as this one are rare. The incidence of sutural bones in this study is similar to what another study on concurrent populations has reported. However, location of occurrence of sutural bones observed in this study was similar to all other sutural bone studies including those on dry skulls pointing to probable universality of this statistic. This preliminary study establishes the use of 3D volume rendering of CT scan data to be a valid means to acquire sutural bone data.

Incidence of Wormian Bone in Human Skulls in Rajasthan

Abstract: Wormian bones are formations associated with insufficient growth at suture closure and are regarded as epigenetic and hypostatic traits. There exists racial variation in its incidence. AIM: To find the incidence of wormian bone and compare with other study.
