The long axis of the talus is angled plantarward in relation to the first metatarsal, consistent with pes planus. The long axis of the talus intersects that of the first metatarsal.Д«. An angle greater than 4 degrees convex upward is considered a pes cavus( 10, 11).ДЄ. An angle that is greater than 4В° convex downward is considered pes planus (Fig b) with an angle of 15В° - 30В° considered moderate, and greater than 30В° severe ( 8, 9). In the normal weight-bearing foot, the midline axis of the talus is in line with the midline axis of the first metatarsal. Collapse may occur at the talonavicular joint, naviculo-cuneiform, or cuneiform-metatarsal joints. This line is used as a measurement of collapse of the longitudinal arch. This is an angle formed between the long axis of the talus and first metatarsal on a weight-bearing lateral view (Fig a). Probably the most familiar line to radiologists, and a more direct measurement of pes planus, or collapse of the longitudinal arch, is the talar-1st metatarsal angle (Meary's angle)(3). Radiographic Measurements (List of All Measurements) This variability in presentation underscores the need to take into account all available information, both clinical and radiographic, when evaluating foot alignment abnormalities. Thus, it is important to be able to recognize early radiographic signs. There is a functional relationship between the structure of the arch of the foot.

In addition, the onset of flatfoot deformity is often insidious. Flat feet (also called pes planus or fallen arches) is a postural deformity in which the arches of the foot collapse, with the entire sole of the foot coming into complete or near-complete contact with the ground. some cases with extensive radiographic deformities may be asymptomatic whereas other cases of mild deformity may be significantly symptomatic. The severity of flatfoot deformity on radiographs does not correlate well with symptoms, i.e. Thus, although the inciting factor leading to the development of flatfoot is not well understood, it is clear that injury to both dynamic and static structures in the foot are responsible for the deformity we call flatfoot.

Mosby Multimedia, 1995)ДЄlthough the etiology of symptomatic adult flatfoot is still debated, most agree that it is produced by abnormal repetetive loading on the medial column, which leads to attenuation or dysfunction of the ligamentous and tendinous stabilizers of the medial column, resulting in the bony deformities seen both clinically and radiographically.
