The author presents a description of three geometric models to serve as a framework for establishing a numerical classification system of unlimited refinement for structural variations of the foot and foot types. Such a classification system may identify different forms (foot types) that may be closely aligned to complex movements of the foot (dynamic foot function). This may help in the diagnosis and treatment of biomechanical disabilities. Clinical evaluations are based on radiographic landmark data from weightbearing radiographs.
The authors report on a 3-year prospective program that included foot-health education and an initial assessment of foot problems in an older population. The program represents a cooperative effort by the Philadelphia Corporation for Aging and the Pennsylvania College of Podiatric Medicine to enhance the quality of life of older citizens. The results show that foot problems are prevalent among older patients. The program also refined a protocol that can be applied in other settings.
