Abstract

Objective: To evaluation of the results of surgical reconstruction of thumb amputation by toes transfer. Subject and method: 42 cases of thumb amputee underwent toe transfer surgery, in which 39 cases transferred the second toe and 3 cases transferred the big toe. The implementation period was from March 2010 to December 2021. The follow-up time average is 26 months (from 12 to 39 months). Results: The average age is 24.7 (17-58 years old), and the male/female ratio is 39/3. According to the scale, The average score of hand function from Michigan: Patient satisfaction is 75.3%, and finger function 79.3%, activities of daily living is 84.1%. The survival rate of the moving finger is 42/42. Thumb key pinch is 70.6%, 2-point (tip) pinch 82.8%, three jaw (palmar) pinch 79.2% and grip force is 80.1% compared to the good hand. The average point for distinguishing the sense of 2 static points is 15,1mm. The results were close to 12/42 cases of flexor tendon adhesions that needed to be released. 3/42 cases of thromboembolic complications were detected timely and re-connected arteries and veins. The second toe part does not affect the function of many places to take the toe. There are 9/39 cases of pain on the soles of the feet, the part that takes the big toe to transfer has 2/3 cases of slight imbalance in the bearing point. Aesthetically, the relative transition of the thumb to replace the thumb is slightly larger than the healthy hand and the second toe to replace the thumb is slightly smaller than the healthy hand. Conclusion: Toe transfer surgery restores the thumb with good functional results, restores motor function and gives patients confidence in daily life.
