Collagen 2A Type B Induction after 3D Bioprinting Chondrocytes In Situ into Osteoarthritic Chondral Tibial Lesion. B Gatenholm, C Lindahl, M Brittberg, S Simonsson.

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…

Do commonly available round facemasks fit near-term and term infants? Haase B, Badinska AM, Koos B, et al.

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…

Comparative Analysis of Three-Dimensional Nasal Shape of Casts from Patients With Unilateral Cleft Lip and Palate Treated at Two Institutions Following Rotation Advancement Only (Iowa) or Nasoalveolar Molding and Rotation Advancement in Conjunction With Primary Rhinoplasty (New York). B Hosseinian, MS Rubin et al.

Date: November 2018. Source: Cleft Palate-Craniofacial Journal, Volume 55, issue 10, pp 1350-1357. Objective: To compare 3-dimensional nasal symmetry in patients with UCLP who had either rotation advancement alone or nasoalveolar molding (NAM) followed by rotation advancement in conjunction with primary nasal repair. Methods: Nasal casts of 23 patients with UCLP from 2 institutions were…

Regression of cephalic index following endoscopic repair of sagittal synostosis. NA Pickersgill, GB Skolnick, SD Naidoo, MD Smyth, KB Patel.

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…

Applications and limitations of using patient-specific 3D printed molds in autologous breast reconstruction. S Hummelink, AC Verhulst, TJJ Maal, DJO Ulrich.

Date: October 2018. Source: European Journal of Plastic Surgery, Volume 41, Issue 5, pp 571–576. Background: Over the last years, several techniques have been proposed to improve the outcome of autologous breast reconstruction procedures. One of these innovations describes patient-specific, three-dimensional (3D) printed breast molds for intraoperative use based on 3D stereophotogrammetry. In this article,…

Effect of surrogate design on the measured stiffness of snowboarding wrist protectors. C Adams, D James, T Senior, T Allen, N Hamilton.

Date: September 2018. Source: Sports Engineering, Volume 21, Issue 3, pp 217–225. Abstract: In snowboarding, the wrist is the most common injury site, as snowboarders often put their arms out to cushion a fall. This can result in a compressive load through the carpals coupled with wrist hyperextension, leading to ligament sprains or carpal and…

Development of three-dimensional facial expression models using morphing methods for fabricating facial prostheses. A Matsuoka, F Yoshioka, S Ozawa, J Takebe.

Date: September 2018. Source: Journal of Prosthodontic Research. Purpose: It is essential to fabricate a best-fit three-dimensional (3D) facial prosthesis model capable of facial expressions. In order for the facial prosthesis to remain in position, especially around marginal areas subject to movement, a new method of making 3D facial expression models using time-series data allowing…

Assessing calvarial vault constriction associated with helmet therapy in deformational plagiocephaly. EC Peterson, KB Patel, GB Skolnick, KD Pfeifauf, KN Davidson, MD Smyth, SD Naidoo.

Date: Aug 2018. Source: Journal of Neurosurgery: Pediatrics. Volume 22: Issue 2: pp 113-221. Objective: Deformational plagiocephaly and/or brachycephaly (DPB) is a cranial flattening frequently treated in pediatric craniofacial centers. The standard of care for DPB involves patient positioning or helmet therapy. Orthotic therapy successfully reduces cranial asymmetry, but there is concern over whether the…
