The presented clinical case demonstrates the advantages of one-stage replacement of the metacarpal defect (in osteoblastoclastoma) with the involvement of the distal articular head with the help of bone-articular avascular auto-transplant of the third metatarsal bone. The use of bone-articular avascular graft of the third metatarsal bone allowed almost perfectly compensate for the defect of the metacarpal bone. Optimal functional and aesthetic results with complete restoration of the lost anatomy were obtained. The duration of the operation was 1 hour 45 minutes.
