title: Design and fabrication of a finger prosthesis based on a new method of suspension.
abstract: OBJECTIVE
  Finger amputation is one of the most common types of amputation. Prosthesis with adequate suspension, user-friendly design, and an aesthetic appearance can be effective in the rehabilitation of these patients. The aim of this technical note was to propose a technique for fabrication of finger prosthesis with a new suspension approach for such patients.
  
  
  METHODS
  To design and accurately fabricate the socket of finger prosthesis, the socket was reduced by 2 mm less than the original value, and a central tunnel with 4 mm width and depth with length matching the distance between the end of the stump and the nail section was provided, so that the silicone material extended to the stump to provide appreciable suspension.
  
  
  CONCLUSIONS
  This study demonstrated the design and fabrication of a silicone finger prosthesis. It also showed silicone finger prosthesis with acceptable suspension, a user-friendly and light design, and a cosmetic appearance constructed for a patient with finger amputation.
  
  
  CONCLUSIONS
  Patients with finger amputation usually use prostheses with a simple suspension technique, but evidence suggests that the residuum of these patients experience atrophy and subsequently loss of appropriate suspension. Therefore, this study was required to provide an alternative suspension method in patients with finger amputations.
