Abstract		Background: Literature mostly describes the cosmetic role of prostheses for finger amputation. The impact on hand function has not been systematically explored. Objectives: Our aim was to describe the impact of silicone finger prostheses on hand function and gripping ability. Study design: Prospective descriptive cross-sectional study. Methods: We included 42 adult patients with partial or complete single- or multiple-digit amputation of one hand. We evaluated hand function of the injured hand without and with the prosthesis with the Southampton Hand Assessment Procedure, and grip power and tracking ability with a grip-force tracking system. Results: Southampton Hand Assessment Procedure grip index scores were slightly higher when using the prosthesis as compared to not using it (though not reaching the minimum real difference reported in the literature), except for lateral grip. Grip power was not significantly affected by prosthesis use for power grip and lateral grip and slightly diminished for tip grip. Tracking errors only differed with respect to the signal type but not with respect to using the prosthesis. Conclusion: A minimum improvement of hand function can be expected at best with silicone prostheses for finger amputation, accompanied by a slight decrease in tip grip power. Clinical relevance Based on our results, an evidence-based explanation can be given to patients after finger amputation regarding the functional benefits that can be expected from a silicone prosthesis.
