Prosthetic rehabilitation of 2 missing digits using a customized ring attachment–supported device: A detailed case report

Traumatic finger amputations are common upper-limb injuries, often resulting from accidents involving machinery, workplace incidents, motor vehicle collisions, or sports-related injuries. Epidemiological studies suggest that traumatic finger amputations constitute 3% of emergencies treated in hand clinics, with 40% of cases resulting from workplace accidents. These injuries can range in severity, sometimes requiring partial or full amputation of the affected digits. The loss of 1 or more fingers has profound functional and psychological impacts on patients, affecting hand dexterity, grip strength, and quality of life. Recent advances in prosthetic rehabilitation have enabled customized solutions that address both aesthetic and functional demands. Although myoelectric and surgically integrated prosthetic options offer advanced functionality, their cost complexity, infrastructure requirements often limit accessibility, particularly in low-resource setting. Passive silicone finger prosthesis remains a widely accepted alternative for restoring appearance and providing limited functional assistance. This case report describes the prosthetic rehabilitation of a young male with complete absence of the ring (D4) and little (D5) fingers using a customized silicone prosthesis retained by a dual-ring attachment-supported framework. The design aimed to achieve acceptable aesthetics, secure retention, reduced prosthesis weight, and limited functional support. The clinical outcome, patient's satisfaction, functional utility, and limitations of the prosthesis are discussed in comparison with existing passive, functional, and myoelectric options.
