A modification of the technique of Chuinard and Peterson for
distraction-compression arthrodesis of the ankle was used in twelve
patients, whose ages ranged from ten to seventy-one years. This modified
technique allows positioning that is better for function and it makes
fusion more certain. It also offers the advantages of the original
technique--that is, it preserves the potential for growth of the distal
tibial and fibular physes and it maintains the height of the malleolus and
foot. The duration of follow-up averaged four years and three months. The
preoperative diagnoses were degenerative arthritis, poliomyelitis, talipes
equinovarus, and myelodysplasia. Solid fusion was achieved in all patients,
although one patient needed reoperation before fusion was achieved. The
time to fusion averaged eleven months (range, three to sixteen months). The
functional result was good in all patients.
