Internal compression arthrodesis of the ankle.

Eight patients with disabling tibiotalar arthritis (one patient with a supramalleolar nonunion) were treated by arthrodesis. The procedure in all of these patients consisted of internal compression obtained by bone plates and the application of a bilateral tension device. A bilateral surgical approach was used. No bone grafting was required. This study compares two groups immobilized for ten and three weeks, respectively. In both groups, the procedure invariably produced union with excellent cosmesis, few complications, and good function.
