Arthroereisis of the Subtalar Joint: An Uncommon Complication and Literature Review

Arthroereisis is an operation to prevent abnormal pronation in the subtalar joint in children and adults with symptomatic flexible flatfeet. In the present report, we describe an uncommon late complication of a former variation of this procedure, namely the case of an adult male who experienced migration of a xenogeneic bone graft that had been implanted 55 years earlier. A thorough review of the existing data was also undertaken to better understand the complications of this procedure.
