The values of talonavicular angles in patients with pes planus.
Talonavicular angles of 42 patients with flatfeet were measured using their weightbearing and nonweight-bearing anteroposterior and lateral radiographs. These patients were divided into two subgroups depending on the presence of pain. The normal feet of 22 people were included in this study to establish the control group. It was observed that, at the weightbearing position, the talonavicular angle increases. The talonavicular angle decreases in pes planus on the lateral radiographs. In patients presenting painful flatfeet, the talonavicular angle significantly reduces in the nonweightbearing anteroposterior x ray. The reason for pain may be enlargement of the medial border of the navicular bone or the presence of an accessory navicular bone. Relief of pain was observed in four patients following removal of the accessory navicular bone.
