A retrospective study involving thirty-six patients with thirty-seven ankle fusions was undertaken to assess the rate of fusion, the subjective and objective results, the residual subtalar and midtarsal movement, and the functional disability. Fusion occurred in thirty-one ankles (84 per cent). Twenty-four patients were reviewed, on average 7.5 years after fusion, and eighteen had good or excellent results; only four had been unable to return to their previous employment. The conclusion is that fusion is still a good treatment for the painful post-traumatic arthritis ankle, the resulting functional disability being minimal.
