This study believes 3D printed templates usage increases time efficiency, improves the match of skin flaps in donor and recipient arms, and allows us to control the amount of skin surplus without skin flap tip necrosis. In these procedures where time is of the essence, this team believes pre-operative planning is imperative for its success.

Date: February 2020. Source: CARTILAGE. https://doi.org/10.1177/1947603520903788 Objective: Large cartilage defects and osteoarthritis (OA) cause cartilage loss and remain a therapeutic challenge. Three-dimensional (3D) bioprinting with autologous cells using a computer-aided design (CAD) model generated from 3D imaging has the potential to reconstruct patient-specific features that match an articular joint lesion. Design: To scan a human…

Date: September 2019 (ONLINE) Source: Archives of Disease in Childhood – Fetal and Neonatal Edition, doi: 10.1136/archdischild-2019-317531. Objective: With inappropriately large facemasks, it is more difficult to create a seal on the face, potentially leading to ineffective ventilation during neonatal stabilisation. We investigated whether commonly available round facemasks are of appropriate size by measuring facial…

Date: October 2018. Source: Journal of Neurosurgery: Pediatrics [Online Before Print]. Objective: Metrics used to quantify preoperative severity and postoperative outcomes for patients with sagittal synostosis include cephalic index (CI), the well-known standard, and the recently described adjusted cephalic index (aCI), which accounts for altered euryon location. This study tracks the time course of these…
