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…

Precision Rhinoplasty Using Virtual Surgical Planning and Departmentally-Manufactured, 3D-Printed, Sterilizable, Patient-Specific Anatomic Models. SG Maliha, JM Bekisz, HA Liss, L Witek, PG Coelho, RL Flores.

Date: August 2018. Source: Plastic and Reconstructive Surgery, Volume 6, Issue 8S, pp 87–88. Goals and Purpose: Rhinoplasty relies on clear patient communication and precise execution of a three-dimensional (3D) plan to achieve optimal results.1 3D printing is becoming more popularized in the medical field as an aid to technical planning, patient communication, and the…

Craniomaxillofacial Reconstruction Based on 3D Modeling. GT Grant.

Date: June 2018. Source: Digital Technologies in Craniomaxillofacial Surgery, pp 55-65. Abstract: Current treatment planning and reconstruction of craniofacial trauma has been advanced greatly due to the increase in the use of software to convert medical image files in the form of Digital Imaging and Communications in Medicine (DICOM) to 3D reconstructions and ultimately files…

Patient-specific 3D Models Providing a 21st Century Approach to Reconstructive Surgery. H Liss, SG Maliha, L Witek et al.

Date: April 2018. Source: Society For Biomaterials 2018 Annual Conference and Exposition, Atlanta, GA, USA. Statement of Purpose: Through the implementation of 3D- printed models in the operating room, plastic surgeons are able to visualize and reconstruct key anatomical features for patients seeking an autogenous ear reconstruction or rhinoplasty. The 3D-printed constructs are sterilizable patient-specific,…

3D Modelling of Facial Skin Surface for 3D Printing. Emma Ekberg.

Date: December 2017. Source: Master’s Thesis 2017:EX056, CHALMERS UNIVERSITY OF TECHNOLOGY. Abstract:One of the major global health problems today is burns, with an estimate of 256000 deaths each year caused by fires [1]. For more severe burns the probability of infections increases and here the golden standard is to use autologous skin grafts. However, the…

Analysis Methods of the Variation of Facial Size and Shape Based on 3d Face Scan Images. W. Lee, L Goto, J.F.M. Molenbroek, R.H.M. Goossens.

Date: October 2017. Source: Proceedings of the Human Factors and Ergonomics Society Annual Meeting. Volume: 61 issue: 1, page(s): 1409-1413. Abstract: 3D scan images have been successfully applied in ergonomic product design. Features of human body parts (e.g., landmarks, measurements, curvatures, surfaces, volumes) extracted from 3D body scan images can be used to analyze variations…

Patient-Specific 3D Models for Autogenous Ear Reconstruction. KS Khouri; HA Liss; JM Bekisz; PG Coelho; RL Flores; L Witek.

Date: September 2017. Source: Plastic and Reconstructive Surgery. 5(9S):174–175, DOI: 10.1097/01.GOX.0000526416.08852.96. Introduction: Autogenous ear reconstruction remains one of the most technically challenging procedures in plastic surgery. Current standards of practice entail tracing the unaffected contralateral ear and using this two-dimensional outline as a surgical model. We present the effectiveness and feasibility of sterilizable, patient-specific and…

Concurrent surface electromyography and force myography classification during times of prosthetic socket shift and user fatigue. J Sanford, R Patterson, DO Popa.

Date: August 2017. Source: Journal of Rehabilitation and Assistive Technologies Engineering. Objective: Surface electromyography has been a long-standing source of signals for control of powered prosthetic devices. By contrast, force myography is a more recent alternative to surface electromyography that has the potential to enhance reliability and avoid operational challenges of surface electromyography during use.…
