The strip craniectomy incisions were replicated across the segmented parietal bones. Areas across the calvarial were selected and constrained to represent the helmet placement after surgery. Skull growth was modelled and three variations of helmet therapy were investigated, where the timings of helmet removal alternated between 2, 5, and 8\u00a0months after surgery.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>The predicted outcomes suggest that the prolonging of helmet placement has perhaps a beneficial impact on the postoperative long-term morphology of the skull. No considerable difference was found on the pattern of contact pressure at the interface of growing intracranial volume and the skull between the considered helmeting durations.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Although the validation of these simulations could not be performed, these simulations showed that the duration of helmet therapy after endoscopically assisted strip craniectomy influenced the cephalic index at 36\u00a0months. Further studies require to validate these preliminary findings yet this study can lay the foundations for further studies to advance our fundamental understanding of mechanics of helmet therapy.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00381-022-05792-1","type":"journal-article","created":{"date-parts":[[2022,12,24]],"date-time":"2022-12-24T12:02:36Z","timestamp":1671883356000},"page":"989-996","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["A preliminary analysis of replicating the biomechanics of helmet therapy for sagittal craniosynostosis"],"prefix":"10.1007","volume":"39","author":[{"given":"Connor","family":"Cross","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans","family":"Delye","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roman H.","family":"Khonsari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mehran","family":"Moazen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,12,24]]},"reference":[{"key":"5792_CR1","doi-asserted-by":"publisher","first-page":"369","DOI":"10.1038\/ejhg.2010.235","volume":"19","author":"D Johnson","year":"2011","unstructured":"Johnson D, Wilkie AOM (2011) Craniosynostosis.
