On anteroposterior view of both feet, note in symptomatic left foot uncovering of talar head as navicular and remaining part of foot move laterally into abduction. Intermetatarsal spaces at their base appear slightly widened; metatarsal-tarsal articulations appear in fact better than in right asymptomatic foot as result of pronation of forefoot. A, Divergence of anteroposterior talocalcaneal angle (Kite angle) is present. B, Standing lateral view shows plantarflexion of talus (head of talus moves plantarward, medially, and distally), loss of normal calcaneal pitch (and concomitant tightening of Achilles tendon), secondary collapse of navicular-cuneiform articular surfaces, and overlapping of medial four metatarsals from pronation of forefoot in weight-bearing position. This patient had traumatic rupture of posterior tibial tendon many years previously while engaging in sports. C, Traumatic arthritic changes followed, and eventually triple arthrodesis was required.
