Ankle fusion: a retrospective review

The results of ankle fusion were reviewed in 26 patients who underwent 32 arthrodesis procedures. Posttraumatic degenerative arthritis was the most common indication for fusion (54%). Crossed cancellous screws were the primary method employed (43%), with an external fixator being used in 22% of cases. The overall union rate was 81%, with both crossed cancellous screws and external fixation attaining the best results (86%). Nonunion and infection were the most frequent complications. Progression of subtalar arthritis was demonstrated in 29% of patients postoperatively. Seventy-eight percent of patients graded extremity appearance as excellent or good, with the majority being able to return to work.
