Massive bilateral tarsal ankylosis and surgical correction: a case report.

Tarsal ankylosis is described as a feature of advanced juvenile or rheumatoid arthritis. Ankylosis involving more then one tarsal segment is uncommon. Incidental reports of massive tarsal ankylosis have been described in a case of juvenile spondyloarthropathy, a case of familial tarsal ankylosis, and, more recently, it was discovered in a prehistoric skeleton dating back to the Iron Age. We describe a rare case of bilateral massive tarsal ankylosis, and the surgical intervention used to treat the condition, in a 21-year-old female with no other features of any known forms of arthritis and no family history of the condition.
