In direct skeletal attachment (DSA) of limb prostheses, a construct is implanted into an amputee's residuum bone and protrudes out of the residuum's skin. This technology represents an alternative to traditional suspension of prostheses via various socket systems, with clear indications when the sockets cannot be properly fitted. Contemporary DSA was invented in the 1990s, and several implant systems have been introduced since then. The current review is intended to compare the design features of implants for DSA whose use in humans or in animal studies has been reported in the literature.
在肢体假肢的直接骨骼附着(DSA)中,将一种结构植入截肢者的残肢骨中,并从残肢的皮肤中伸出。这项技术代表了通过各种套接系统来悬挂假肢的传统方法的替代方案,在套接系统无法正确适配时具有明确的适应症。现代的 DSA 技术是在 20 世纪 90 年代发明的,此后已经引入了几种植入系统。本综述旨在比较文献中报道的在人体或动物研究中使用的 DSA 植入物的设计特点。
