case_images: His right hand injuries included predominantly full-thickness burns to the thumb, index, and long fingers, a dysvascular thumb beyond the interphalangeal joint (IP) and blast injuries causing segmental loss of the flexor digitorum superficialis (FDS) and flexor digitorum profundus (FDP) of the index finger (Figures 1 and 2).

case_images: Due to a complex social situation and poor function of the long finger flexors and extensors, the decision was made to transpose the long finger as a fixed/stable 'post' to the thumb position (Figures 6 and 7).

case_images: Using a sagittal saw the right long finger was transected through the proximal phalanx close to the MP joint and part of the remaining metacarpal removed as a ray resection to deepen the webspace and improve prehension (Figure 9).
