A custom-designed finger prosthesis replaces a portion or all of an absent finger. If the patient has movement in the remaining portion of the finger, the prosthesis will restore the function of the finger. This type of prosthesis is attached by suction or adhesive. The prosthesis will protect the sensitive tip of the finger from trauma and extreme temperatures. It will allow the patient to type or use a computer keyboard correctly and without discomfort. It also serves as a great psychological benefit in the rehabilitation of the patient.
