Current indications for single digit replantation.

The functional outcome of 67 successfully replanted single digits (excluding the thumb) involving 31 complete and 36 incomplete nonviable amputations was found to be strictly related to the level of the amputation. While the survival rate was higher in patients with incomplete nonviable amputations (89 percent), compared to those with complete amputations (81 percent), the ability of the patient to use their digit was almost uniform among both groups of patients. All except 2 of the 9 digits with complete amputations at the level of the proximal phalanx or at the proximal interphalangeal joint (PIP) resulted in limited motion (less than 20 degrees-30 degrees) at the PIP and distal interphalangeal (DIP) joints. Only 9 from the group of patients with incomplete nonviable amputations at the proximal phalanx exceeded flexion greater than 40 degrees at the PIP joint. From these results, we conclude that the indications for replantation of a single digit amputation should be as follows: 1) amputation distal to the insertion of the flexor digitorum sublimis; 2) ring injuries type II and IIIa; and 3) amputations at the level of or distal to the DIP joint.

Vascularised bone grafts in the treatment of long bone defects.

Reconstruction of large bony defects of long bones was performed using vascularised fibular grafts in four patients at the Department of Orthopaedic Surgery of the University of Ioannina Medical School. Indications for grafting procedures in this small series had been the loss of bone due to the extensive resection of avascular and necrotic bone from septic pseudoarthrosis in three patients and congenital pseudarthrosis secondary to neurofibromatosis in a child. Primary skeletal union with graft hypertrophy occurred in three of the patients. The fourth patient had an asymptomatic nonunion at the proximal end of the graft. The result in each patient was the presence of a well-aligned limb that had normal or nearly normal motion and acceptable length.
