Abstract
Despite intensive research and development of systems for restoration of sensory information, these have so far only been the subject of study protocols. A new noninvasive feedback system translates pressure loads on the forefoot and hindfoot into gait-synchronized vibrotactile stimulation of a defined skin area. To increase the authenticity, this treatment can be supplemented by a surgical procedure. Targeted sensory reinnervation (TSR) describes a microsurgical procedure in which a defined skin area on the amputated stump of the residual limb is first denervated and then reinnervated by a specific, transposed sensory nerve harvested from the amputated part of the limb. This creates a sensory interface at the residual stump. This article presents the clinical and orthopedic technical treatment pathway with this innovative vibrotactile feedback system and explains in detail the surgical procedure of TSR after amputation of the lower limb.
尽管对恢复感觉信息的系统进行了深入研究和开发，但迄今为止，这些系统还只是研究方案的主题。一种新的非侵入式反馈系统能将前足和后足的压力负荷转化为对特定皮肤区域的步态同步振动触觉刺激。为提高疗效，还可辅以外科手术。靶向感觉再支配（TSR）描述了一种显微外科手术，首先对残肢截肢残端上的特定皮肤区域进行去神经支配，然后通过从肢体截肢部位获取的特定移位感觉神经进行再支配。这样就在残肢残端形成了一个感觉界面。本文介绍了这种创新型振动触觉反馈系统的临床和矫形技术治疗途径，并详细解释了下肢截肢后 TSR 的手术过程。
