traumatized Index Finger pollicization for thumb reconstruction
Journal of Hand Surgery (European Volume), 2008Co-Authors: Cesar J Bravo, Todd Horton, Steven L Moran, Alexander Y ShinAbstract:Purpose When the Index Finger is injured or severed in conjunction with a traumatic amputation of the thumb, transfer of the injured Index Finger can restore the important function of the thumb. The purpose of this study is to evaluate the results of the transfer of an injured Index Finger for traumatic loss of the thumb. Methods Seven patients treated by pedicled transfer of a traumatized Index Finger after amputation to the ipsilateral thumb were reviewed retrospectively. Postoperative evaluations included thumb range of motion, opposition and pinch function, grasp and pinch strength, sensation, a pick-up test, and a patient-rated appearance of the thumb and hand. Vascular patency of the traumatized Index Finger and thumb was evaluated in each patient prior to thumb reconstruction. Results After an average of 4 years of follow-up for surviving patients, all had excellent postoperative function and satisfactory results. The period between injury and thumb reconstruction ranged from 5 months to 4 years. All patients were men with a mean age of 43 years. Amputation levels included the metacarpophalangeal joint in 2 patients, the first metacarpal in 2 patients, and the proximal phalanx in 3 patients. All transferred traumatic Index Fingers survived without complications. Conclusions Transfer of the injured Index Finger to the amputated thumb serves as an excellent adjunct for treatment of traumatic thumb amputations/crush injuries. Consistent results can be obtained while maintaining opposition and protective sensation after this procedure. However, technical demands are great, and initial injuries to the thumb and Index Finger ultimately determine the final outcomes. Type of study/level of evidence Therapeutic IV.

Index Finger rehabilitation/assistive device
2012 4th IEEE RAS & EMBS International Conference on Biomedical Robotics and Biomechatronics (BioRob), 2012Co-Authors: Andrea Polotto, Francesco Modulo, Fabio Flumian, Zhen Gang Xiao, Paolo Boscariol, Carlo MenonAbstract:In this paper, a novel exoskeleton for the Index Finger is introduced. Such a device is intended to be used for the rehabilitation of post-stroke patients. The target of the design is to produce a device with low weight and reduced space occupation, so that it can be worn without interfering with everyday use of the hand. The actuation is provided using low-cost lightweight miniature DC motors, and position feedback is obtained trough potentiometers. A working prototype has been built and tested. A closed-loop position control with friction compensation has been implemented and experimental results are presented and discussed.
