New aspects of the hand finger reconstruction by distraction technique
Abstract
Purpose. To develop a new technology for transferring the pre-existing blood-supplied refused osteocutaneous structures of bone segments pre-formed by distraction technique for finger reconstruction.
Materials and Methods. A new technology presented in order to reconstruct fingers of the hand for its injury consequences which consists in transferring the hand refused segments on distracted pedicles. The technique has been used for treatment of 64 patients with 84 fingers reconstructed. Full-length finger transferred in three cases (3.7%), finger stump – in 33 cases (40.7%), and metacarpal stump – in 45 cases (55.6%). Long-term results of treatment studied by clinical, X-ray, biomechanical, biophysical, and morphological methods. They estimated according to A.E. Belousov technique perfected by the authors.
Results. Excellent results obtained in 40.0% of patients, good ones – in 5.0%, satisfactory – in 47.5%, and unsatisfactory – in 7.5% of patients. The resistance of the transferred segment bone skeleton to resorption has been proved. The indications for the technique use have been determined depending on the hand defect type.
Conclusion. The approach developed allows to broaden the possibilities of finger reconstruction significantly due to local donor resources for the consequences of mechanical, gunshot, and thermal injury. Moreover, the technique allows to achieve qualitatively new results with minimal donor faults in patients with different types of the hand posttraumatic defects
