1. The procedure described for reconstruction of a useful hand after loss of a central finger or the thumb has been carried out twenty-seven times with slight modification. Various tendon transplantations and grafts were frequently done at the same time. The method consists in transposing the adjacent finger and metacarpal into the defect, thus restoring the parallel alignment of the remaining fingers. In loss of the ring finger, the fifth metacarpal is transposed to the base of the fourth metacarpal. When the long finger is missing, the second metacarpal is transposed to the base of the third metacarpal.
2. The method described for reconstruction of the thumb after amputation consists in transposing the index finger to the first metacarpal, after shortening the index finger to the proper length; then rotating it to the proper position for opposition, and maintaining its blood and nerve supply and tendon control.
