For infants and small toddlers with congenital upper limb deficiencies, terminal devices mainly provide either cosmesis or functionality. We report a clinical note about fitting a child with a low-cost passive hand targeting both functionality and cosmesis.
An elastomeric, alloy-wire-reinforced hand was fabricated using additive manufacturing to allow independent positioning of the digits. A clinical pilot in-home evaluation was conducted on a child with upper limb loss.
The fabricated hand met the functional requirements but required a cover for cosmesis due to a poor surface finish associated with the fabrication technique. The participant child was comfortable using the prosthesis for various tasks. The parents were satisfied with the hand's function and cosmesis when covered with a cosmetic glove. This work demonstrated a new design and process that may in the future improve the utilization of prosthetic hands to promote early prosthesis use and a child's development.
Early prosthesis use is important for infants and toddlers. Additive manufacturing may enable the fabrication of custom passive prosthetic hands that provide both cosmesis and functionality.
对于患有先天性上肢缺损的婴幼儿，终端装置主要提供美容或功能。我们报告一份关于为一名儿童安装兼具功能与美容的低成本被动手的临床记录。
采用增材制造技术制作了一种弹性体、合金丝增强的手，使手指能够独立定位。对一名上肢缺失儿童进行了临床试点家庭评估。
制作的手满足功能要求，但由于制作技术导致表面光洁度差，需要一个套子来进行美容。参与的儿童使用该假肢进行各种任务时感到舒适。当戴上美容手套时，家长对该手的功能和美容效果感到满意。这项工作展示了一种新的设计和工艺，未来可能会提高假肢手的利用率，促进早期假肢使用和儿童发育。
早期使用假肢对婴幼儿很重要。增材制造可以制作出兼具美容和功能的定制被动假肢手。
