| Abstract: | Loss of a thumb accounts for 60% decrease of functional value of the hand, thus any attempt of it's reconstruction is a priority in the field of hand surgery. Optimal reconstructive solution for subtotal thumb amputations has not been settled. The results of partial pollicization of ring finger in 5 adult men is presented. Four patients sustained distal subtotal thumb amputation (MCP joint level), one total amputation. In three patients the distal phalange of the ring finger was transferred with the DIP joint, FDP tendon and a fragment of extensor tendon. An effective movement of a newly created thumb's IP joint was achieved in two patients. In one patient with a total thumb amputation the transfer was followed by a pollicization of the second metacarpal with remnants of proximal phalange. The postoperative course was uneventful in all of the patients. The sensitivity tested on the pulp of the transferred finger equalized to the preoperative value, the hand strength was not diminished. The cosmetic result was excellent. |
