Tarsal navicular position after complete soft-tissue clubfoot release.

The navicular position was evaluated (according to Simons' criteria) on anteroposterior and lateral roentgenograms of 45 clubfeet that were treated with complete soft-tissue release without internal fixation. The evaluation was performed an average of 28 months after surgery. Position of the navicular correlates well with the functional rating score system. Navicular position can be viewed as an indicator for clubfoot correction. Internal fixation of the talonavicular joint was correlated with favorable correction of deformity.
