Abstract


Introduction. Tarsal coalition is congenital bony, cartilaginous, or fibrous fusion between tarsal bones. The most specific clinical feature of these patients is limitation of tarsal joints mobility. Foot mobility is evaluated using a few clinical tests-tip-toe test, Jack test, and manual evaluation of passive foot inversion/eversion. However, these tests do not have high rates of sensitivity and specificity, and cannot be used to make differential diagnosis among the different types of coalitions.

Aims. To improve the clinical diagnosis of calcaneonavicular coalitions.

Materials and methods. We present a new clinical test-evaluation of calcaneonavicular segment mobility. To evaluate this test, we studied a group of 100 children (155 feet), which included those with talocalcaneal coalitions (22 patients/30 feet), calcaneonavicular coalitions (28 patients/45 feet), and those without tarsal coalitions (50 patients/80 feet).

Results. The sensitivity of the test was 95.6%, and specificity was 93.3%. This test had good reproducibility, as evidenced by the inter-rater reliability coefficient of 0.818.

Conclusions. The clinical test presented here can be used to identify patients with calcaneonavicular coalitions, which could not be identified using other clinical tests of foot mobility
