A prosthetic limb aims to support its user by restoring missing functionality. The acceptance of a prosthesis is highly influenced by the timely fitting as the timeframe between amputation and prosthetic limb restoration is crucial. A “Golden Period”, the first month after the amputation, has been identified as the optimal time when an upper-limb prosthesis should be fitted to an amputee in order to maximise their chances for a fast and successful return to their daily life. Unfortunately, in most healthcare systems this time window is surpassed. Reasons for this inefficiency can be many, such as administrative hurdles or the many steps necessary in conventional socket fabrication, but the case is made ever more complex due to the fact that the design of each prosthetic socket has to be personally customized to fit an individual amputee. All the more the residual limb often changes its shape in the first weeks after the amputation. To better capitalize on the “Golden Period” and allow for early prosthetic training, we propose an adaptable and versatile temporary transradial socket design capable of multidimensional adjustments and easy user fitting for below elbow amputees. A bone structure inspired design is 3D printed and assembled as to host all relevant myoelectric prosthetic hand components in a wearable prototype. This prototype was evaluated in a monocentric, non-interventional explorative study with both experts and users. The investigation shows that the proposed design is able to appropriately accommodate its diameter and length to user needs. Moreover, according to the conducted survey, it is perceived as satisfactory with respect to both user needs and expectations of the experts. While promising, further improvements towards even more versatile and robust design are needed before wider clinical application.
