Traumatic thumb amputation represents an extremely disabling entity, thus rendering its reconstruction a procedure of paramount importance. A case of a patient, who sustained a traumatic amputation of his left index finger at the metacarpophalangeal joint and of his left thumb in the middle of the proximal phalanx 4 months ago and was initially treated elsewhere, is described. For the thumb reconstruction, an osteocutaneous flap of the radial side of the 2nd metacarpal, which consisted of a 3, 5-cm bony segment with the overlying skin and its blood and nerve supply was used. The flap was transferred and fixed with a plate and screws to the palmar-medial side of the stump of the thumb, while the 1st web space was deepened by removing the rest of the second metacarpal, while a partial skin graft was used to cover a remaining gap. Thumb functionality was restored immediately postoperatively, and the overall result was satisfactory.
