Vascularised bone graft applications in upper extremity problems.

ABSTRACT

Between 1990 and 1996, 16 cases of bone defects were treated by vascularised bone grafting by the authors. Free vascularised fibula was used in 10 cases and one free iliac crest graft was used for upper extremity bone defects. Four vascular pedicled first metacarpal bone and one radial styloid bone were used for scaphoid nonunion. Average follow-up was 26 months (6-78 months) and success rate was 94%. We recommend vascularised bone grafts in the upper extremity when there is risk of infection; the defect is greater than five centimeters when the forearm rotation is unlimited. The avascularity of the scaphoid pseudarthrosis must be verified radiologically or through magnetic resonance imaging. This technique should only be used when other reconstructive techniques are unlikely to succeed.
