METHOD FOR FINGER RESTORATION Russian patent published in 2015 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: at the first stage, the method involves forming dorsal and carpal vascular pedicles of the displaceable metacarpal and finger stump, performing a metacarpal osteotomy followed by the apparatus distraction of a distal fragment of the metacarpal. At the second stage, the formed segment with elongated vascular pedicles is displaced into the position of the missing finger with fixing the bone fragments. On completion of the distraction, the bone fragments of the metacarpal and finger stump are fixed with a brace in the position of maximum spreading with preserving the formed bone graft by the intramedullary insertion of the distal and proximal ends of the brace into the respective fragments of the metacarpal and the homonymous finger stump with the maximum traction of the distal fragment. Six month later, the brace is removed, and the bone graft is transected. The vascular pedicle segment is re-mobilised and dislocated together with the distal part of the formed vascular pedicle bone graft onto the recipient stump. That is followed by performing an osteosynthesis of the bone graft with the distal part of the bony frame of the stump.

EFFECT: method enables forming the finger of an adequate length with the minimum donor defect and prevents contractures by forming the adequate length of the distraction vascular pedicle bone graft.
