Abstract

Fixation for ankle arthrodesis often consists of compression screws. A technique using a mechanically sound configuration for stable fixation is presented. The spatial orientation of the screws is in the form of a tripod that provides circumferential compression across the fusion mass. The sequence of delivery of the hardware minimizes the likelihood of intraosseous screw collision. The strategic placement of the screws also prevents stress concentration that may lead to stress risers in the distal tibia.
