Thumb Reconstruction in Transposition of Residual Index Finger in Severely Burned Hand

Objective To suggest an improved method of thumb reconstruction by means of resiual index finger transposition in the severely burned hand. This method can prevent circulatory disturbance and swelling of the reconstructed thumb which takes place frequently under the regular method. Methods Keeping the radial-sided soft tissues intact, the residual index finger to be transposed was severed from the 2nd metacarpal bone of the middle finger by an incision over the web between the two fingers. Results Sixteen remained index fingers in 15 patients were transposed to the thumb position. No circulatory crisis or swelling of the reconstructed thumb swelling took place. Conclusion This is an easy and safe method for thumb reconstruction in the severely burned hand.
