Hand Function After Fingers Amputation

Abstract

Replantation is the reattachment of a part that has been completely amputated. In developing a treatment plan for multiplex injuries of the hand, the surgeon must keep in mind the seven basic functions of the hand: precision pinch, opposition pinch, key pinch, chuck grip, hook grip, span grasp, and power grasp. Depending on the severity of injury, some of these functions may not be restored. The Aim is to evaluate hand function after fingers amputation. Materials and methods: 21 years old men injured his right hand with comber of wool. The hand was multiplex injured: it were amputations of I-V fingers, dorsal hand site skin defect, soft tissue defects, extensor tendons of fingers defects, metacarpal bones fractures and defects. The first and fifth fingers were replantated. The rotating flap and skin graft were placed into the defect of dorsal site of hand. Results: Fingers were examined after 9 months after replantation. It was observed that the patient did not have difficulty in performing daily activities such as buttoning, use of forks, spoons and handwriting, and had a considerably improved pinching crucial for functional independence losses of active range of motion of the metacarpophalangeal and interphalangeal joints were within the rage of 10 to 30 degrees in both hands. In the assessment of sensation, static and dynamic two-point discrimination test results were 6.3 mm of thumb and 4.1 mm of fifth finger respectively. Conclusions: With loss of the three central digits, the small finger effectively assumes 50% of hand function.
