Ball and socket ankle joint

Dr Vincent Tatco and Dr Henry Knipe et al.

A ball and socket ankle joint is a variant affecting the ankle where there is a rounded or spherical configuration to the talar dome with the corresponding concavity of the tibial plafond. The distal fibula may or may not be involved.


The etiology has been debated with two theories proposed:

  • congenital
  • acquired in early childhood (by age 5) secondary to osseous tarsal coalition
