The hand is associated with both form and function. The loss of a body part, such as a finger or a partial hand, has a profound psychological impact on the patient and significantly reduces their quality of life. A precisely fitting hand prosthesis or complex finger prosthesis can significantly improve function by restoring esthetics, normal length, and function to a great extent, as well as protecting the remnant sensitive stump (if lost due to amputation). Based on their functional capabilities, several types of hand prostheses can be designed, including passive, externally powered, hybrid, and bionic. An implant hand prosthesis is also an option, as it provides a more secure retentive fit. A passive prosthesis is purely cosmetic and does not offer any movement but can be used to stabilize or, at times, carry objects, which could mean a great deal to a person. Most patients prefer the simple glove-type prosthesis with a soft inner lining, primarily driven by affordability, which is held in place by various mechanical retentive means that aid in both function and cosmetic appearance. This article presents a case series of partial/complete hand prostheses. The uniqueness of this case series lies in the fact that various mechanical retentive methods are employed in each case type to achieve both function and appearance. The first case involves a complete hand prosthesis fabricated as a 'hollow' glove-type hand prosthesis, which aims to reduce the weight and, consequently, the cost of the prosthesis. The other case reports involve complex finger prosthesis cases with mechanical aids, such as finger rings and silicone linings, which provide improved comfort and acceptance. It also enables the colour matching of the dorsal and ventral surfaces separately, so that the prosthetic form, colouration, and texture are as indiscernible as possible from the surrounding tissues.
手与形态和功能都相关。身体某部分的缺失，比如一根手指或部分手部，会对患者产生深远的心理影响，并显著降低他们的生活质量。一个精确适配的手部假肢或复杂的手指假肢能够通过极大程度地恢复美观、正常长度和功能，以及保护残余的敏感残端（如果因截肢而缺失），从而显著改善功能。基于其功能能力，可以设计几种类型的手部假肢，包括被动式、外部动力式、混合式和仿生式。植入式手部假肢也是一种选择，因为它能提供更稳固的固定贴合。被动式假肢纯粹是装饰性的，不具备任何活动功能，但可用于稳定物品，有时也能搬运物品，这对患者意义重大。大多数患者更喜欢带有柔软内衬的简单手套式假肢，主要是因为其价格实惠，它通过各种机械固定方式固定在手上，有助于实现功能和美观。本文展示了一系列部分/全手假肢的案例。该案例系列的独特之处在于，每种案例类型都采用了各种机械固定方法来实现功能和外观。第一个案例是制作成“中空”手套式的全手假肢，其目的是减轻重量，进而降低假肢成本。其他案例报告涉及带有机械辅助装置的复杂手指假肢案例，如指环和硅胶内衬，这些装置能提高舒适度和接受度。它还能分别实现背侧和腹侧表面的颜色匹配，使假肢的形态、颜色和质地与周围组织尽可能难以区分。
